* glusterd: move new feature (tiering) enum op to the last of the arrayGaurav Kumar Garg2015-11-031-2/+5
| | | | | | | | | | | | | | | | | | | | Currently new feature tiering have GD_OP_DETACH_TIER and GD_OP_TIER_MIGRATE enum in the middle of the glusterd_op_ enum array. In multi nodes cluster when one of the node upgraded from lower version to higher version and upon executing command can end up in a mismatch in enum ops at the receiver ends causing command execution fail. Fix is to put every new feature glusterd operation enum code to last of the enum array.

* snapshot : copying nfs-ganesha export fileJiffin Tony Thottan2015-10-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While taking snapshot, the export file used by the volume should copy to snap directory. So that when restore of snapshot happens, the volume can retain all its configuration for exporting via nfs-ganesha. The export file is stored at "/etc/ganesha/export" in the following format "export.<volname>.conf" The fix handles given cases in the following manner : case a: The nfs-ganesha(global) is ON during snapshot and restore. i.) Volume was exported during snapshot. When we restore snapshot, then volume should be exported back with old configuration file. ii.) Volume was unexported during snapshot. When we restore snapshot, then volume should unexported again. case b: The nfs-ganesha is ON during snapshot and OFF during restore Volume was exported during snapshot. When we restore snapshot, the conf will be copied to corresponding location and if nfs-ganesha enabled again, then volume will be exported. For the clones, export conf file will created in /etc/ganesha/export and then export it via ganesha.

* snapshot: Fix snapshot clone postvalidateAvra Sengupta2015-10-201-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | In glusterd_snapshot_clone_postvalidate(), we were deleting snap object and snap vol, by looking up snapname. Hence, it was deleting the orignal snapshot from which the clone was being created Instead it should fetch the clonename, the respective clone vol, and its corresponding snap object, and delete them. Also glusterd_snap_remove(), needs to differentiate a clone snap object from a snaphsot snap object, as in case of a clone snap object, we don't have any persisted data in /var/run/gluster/snaps/ and hence is shouldn't try to delete anything there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is part one change to prevent data loss in a replicate volume on doing a replace-brick commit force operation. Problem: After doing replace-brick commit force, there is a chance that self heal happens from the replaced (sink) brick rather than the source brick leading to data loss. Solution: During the commit phase of replace brick, after old brick is brought down, create a temporary mount and perform setfattr operation (on virtual xattr) indicating AFR to mark the replaced brick as sink. As a part of this change replace-brick command is being changed to use mgmt_v3 framework rather than op-state-machine framework. Many thanks to Krishnan Parthasarathi for helping me out on this.

From these peers a volume(gluster_shared_storage) is created. Depending on the number of peers available the volume is either a replica 3 volume(if there are 3 connected peers), or a replica 2 volume(if there are 2 connected peers). "/var/run/gluster/ss_brick" serves as the brick path on each node for the shared storage volume. We also mount the shared storage at "/var/run/gluster/shared_storage" on all the nodes in the cluster as part of enabling this option. If there is only one node in the cluster, or only one node is up then the command will fail Once the volume is created, and mounted the maintainance of the volume like adding-bricks, removing bricks etc., is expected to be the onus of the user.

* dht: make lookup-unhashed=auto do something actually usefulJeff Darcy2015-05-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | The key concept here is to determine whether a directory is "clean" by comparing its last-known-good topology to the current one for the volume. These are stored as "commit hashes" on the directory and the volume root respectively. The volume's commit hash changes whenever a brick is added or removed, and a fix-layout is done. A directory's commit hash changes only when a full rebalance (not just fix-layout) is done on it. If all bricks are present and have a directory commit hash that matches the volume commit hash, then we can assume that every file is in its "proper" place. Therefore, if we look for a file in that proper place and don't find it, we can assume it's not on any other subvolume and *safely* skip the global (broadcast to all) lookup.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When ganesha.enable is set to on and features.ganesha is enabled, there are a few behaviour changes that should be seen in other volume operations. 1. ganesha.enable can be set to 'on' only when features.ganesha is set to 'enable' 2.When gluster vol is started, and if ganesha.enable key was set to 'on', it should automatically export the volume via NFS-Ganesha. 3.When ganesha.enable is set to 'on', and a volume is stopped, that volume should be unexported via NFS-Ganesha. 4. gluster vol reset <volname> If ganesha.enable was set to on, then unexport the volume via NFS-Ganesha. 5. gluster vol reset all If features.ganesha is set to enable, as part of reset all, set it to disable. This translates to teardown cluster. All the above problems are fixed by checking the global key and value, depending on the value, specific functions are called. And also, functions related to global commands are moved to cli-cmd-global.c Commit phase of features.ganesha enable/disable runs the ganesha-ha.sh setup/teardown respectively. Before the script begins, it is important that the NFS-Ganesha service starts on all the HA nodes. Having the start service commands in the commit phase could lead to problems. Moving the pre-requisite service start commands to the 'stage' phase.

* glusterd: Replace transaction peers listsKaushal M2015-04-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Transaction peer lists were used in GlusterD to peers belonging to a transaction. This was needed to prevent newly added peers performing partial transactions, which could be incorrect. This was accomplished by creating a seperate transaction peers list at the beginning of every transaction. A transaction peers list referenced the peerinfo data structures of the peers which were present at the beginning of the transaction. RCU protection of peerinfos referenced by the transaction peers list is a hard problem and difficult to do correctly. To have proper RCU protection of peerinfos, the transaction peers lists have been replaced by an alternative method to identify peers that belong to a transaction. The alternative method is to the global peers list along with generation numbers to identify peers that should belong to a transaction. This change introduces a global peer list generation number, and a generation number for each peerinfo object. Whenever a peerinfo object is created, the global generation number is bumped, and the peerinfos generation number is set to the bumped global generation. With the above changes, the algorithm to identify peers belonging to a transaction with RCU protection is as follows, - At the beginning of a transaction, the current global generation number is saved - To identify if a peers belonging to the transaction, - Start a RCU read critical section - For each peer in the global peers list, - If the peers generation number is not greater than the saved generation number, continue with the action on the peer - End the RCU read critical section The above algorithm guarantees that, - The peer list is not modified when a transaction is iterating through it - The transaction actions are only done on peers that were present when the transaction started But, as a transaction could iterate over the peers list multiple times, the algorithm cannot guarantee that same set of peers will be selected every time. A peer could get deleted between two iterations of the list within a transaction. This problem existed with transaction peers list as well, but unlike before now it will not lead to invalid memory access and potential crashes. This problem will be addressed seprately.

| | | | | | | | | | | | | | | | | | | On Linux systems we should use the libuuid from the distribution and not bundle and statically link the contrib/uuid/ bits. libglusterfs/src/compat-uuid.h has been introduced and should become an abstraction layer for different UUID APIs. Non-Linux operating systems should implement their compatibility layer there. Once all operating systems have an implementation in compat-uuid.h, we can remove contrib/uuid/ from the repository completely.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

It sits above posix and will be loaded on the 3rd (last) brick of every afr subvolume in a replica 3 configuration. It intercepts inode read/write operations: reads are unwound with ENOTCONN, inode writes are unwound with success without actually passing them down to posix.

* glusterd: CLI commands to create and manage tiered volumes.Dan Lambright2015-03-191-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A tiered volume is a normal volume with some number of new bricks representing "hot" storage. The "hot" bricks can be attached or detached dynamically to a normal volume. When this happens, a new graph is constructed. The root of the new graph is an instance of the tier translator. One subvolume of the tier translator leads to the old volume, and another leads to the new hot bricks. attach-tier <VOLNAME> [<replica> <COUNT>] <NEW-BRICK> ... [force] volume detach-tier <VOLNAME> [replica <COUNT>] <BRICK> ... <start|stop|status|commit|force> gluster volume rebalance <volume> tier start gluster volume rebalance <volume> tier stop gluster volume rebalance <volume> tier status The "tier start" CLI command starts a server side daemon. The daemon initiates file level migration based on caching policies. The daemon's status can be monitored and stopped. Note development on the "tier status" command is incomplete. It will be added in a subsequent patch. When the "hot" storage is detached, the tier translator is removed from the graph and the tiered volume reverts to its original state as described in the volume's info file.

* glusterd: Protect the peer list and peerinfos with RCU.Kaushal M2015-03-161-7/+4

Design patterns described in the Paul McKenney's RCU dissertation [1] (sections 5 and 6) have been used to convert existing non-RCU protected code to RCU protected code. Currently, we are only targetting guaranteeing the existence of the peerinfo objects, ie., we are only looking to protect deletes, not all updaters. We chose this, as protecting all updates is a much more complex task. The steps used to accomplish this are, 1. Remove all long lived direct references to peerinfo objects (apart from the peerinfo list). This includes references in glusterd_peerctx_t (RPC), glusterd_friend_sm_event_t (friend state machine) and others. This way no one has a reference to deleted peerinfo object. 2. Replace the direct references with indirect references, ie., use peer uuid and peer hostname as indirect references to the peerinfo object. Any reader or updater now uses the indirect references to get to the actual peerinfo object, using glusterd_peerinfo_find. Cases where a peerinfo cannot be found are handled gracefully. 3. The readers get and use the peerinfo object only within a RCU read critical section. This prevents the object from being deleted/freed when in actual use. 4. The deletion of a peerinfo object is done in a ordered manner (glusterd_peerinfo_destroy). The object is first removed from the peerinfo list using an atomic list remove, but the list head is not reset to allow existing list readers to complete correctly. We wait for readers to complete, before resetting the list head. This removes the object from the list completely. After this no new readers can get a reference to the object, and it can be freed.

Implementing glusterd_dump_priv function to export per-node glusterd information would be useful for debugging bugs. Once implemented, we could enhance sos-report to fetch this information. This would potentially reduce our time to root cause and data needed for debugability can be dumped gradually. Following is the main items of the dump list targeted in this patch : * Supported max/min op-version and current op-version * Information about peer list * Information about peer list involved while a transaction is going on (xaction_peers) * option dictionary in glusterd_conf_t * mgmt_v3_lock in glusterd_conf_t * List of connected clients * uuid of glusterd * A section of rpc related information like live connections and their statistics There are couple of issues which were found during implementation and testing phase: - xaction_peers of glusterd_conf_t was not initialized in init because of which traversing through this list head was crashing when there was no active transaction - gf_free was not setting the typestr to NULL if the the alloc count becomes 0 for a mem-type earlier allocated.

* glusterd: Move brick order check from cli to glusterd.ggarg2014-09-241-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the brick order check for replicate volumes on volume create and add-brick was done by the cli. This check would fail when a hostname wasn't resolvable and would question the user if it was ok to continue. If the user continued, glusterd would fail the command again as the hostname wouldn't be resolvable. This was unnecessary. This change, moves the check from cli into glusterd. The check is now performed during staging of volume create after the bricks have been resolved. This prevents the above condition from occurring. As a result of this change, the user will no longer be questioned and given an option to continue the operation when a bad brick order is given or the brick order check fails. In such a case, the user can use 'force' to bypass the check and allow the command to succeed.

* snapview-server: register a callback with glusterd to get notificationsRaghavendra Bhat2014-09-081-0/+3
| | | | | | | | | | | | | | | * As of now snapview-server is polling (sending rpc requests to glusterd) to get the latest list of snapshots at some regular time intervals (non configurable). Instead of that register a callback with glusterd so that glusterd sends notifications to snapd whenever a snapshot is created/deleted and snapview-server can configure itself.

* geo-rep/glusterd: API to check active geo-rep session for the volumeKotresh H R2014-08-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Requirement: Snapshot needs an API to fail the CLI if any geo-rep session is active for that volume. Solution: A function "gd_vol_is_geo_rep_active" is provided to check if any geo-rep session is active for that volume. An in memory dict called 'gsync_running_slaves' is maintained in 'volinfo' structure to keep track of active geo-rep session for the volume. The key 'slavenode::slavevol' with value 'running' is added whenever geo-rep is started/resumed into the dict and the same is removed if stopped/paused. So the 'count' in dict is used to decide whether the geo-rep is active or not for that volume. Also added "this->name" in gf_log in routines which this patch is touched.

* glusterd/snapshot: Inherit the mount options of a original brickVijaikumar M2014-08-031-0/+1
| | | | | | | | | | | | | | | | | | | | when creating snapshots When creating a snapshot a LVM is created at the backend and is mounted under /var/run/gluster/snaps/... However, this mount does not inherit the mount options for the original brick acting as the parent for the snap. If the snap is restored, this could lead to performance degredations, functional limitations, or in extreme scenarios even potential data loss.

This patch mainly does two things, 1. Extend the peerinfo object to store a list of addresses instead of a single hostname as it does now. This also includes changes to make the peer update behaviour of 'peer probe' to add to the list. 2. Improve glusterd_friend_find_by_hostname() to perform better matching of hostnames. glusterd_friend_find_by_hostname() now does and initial quick string compare against all the peer addresses known to glusterd, after which it tries a more thorough search using address resolution and matching the struc sockaddr's. The above two changes together improve the peer identification situation in glusterd a lot.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two new options have been added to the 'create' command of the cli interface: disperse [<count>] redundancy <count> Both are optional. A dispersed volume is created by specifying, at least, one of them. If 'disperse' is missing or it's present but '<count>' does not, the number of bricks enumerated in the command line is taken as the disperse count. If 'redundancy' is missing, the lowest optimal value is assumed. A configuration is considered optimal (for most workloads) when the disperse count - redundancy count is a power of 2. If the resulting redundancy is 1, the volume is created normally, but if it's greater than 1, a warning is shown to the user and he/she must answer yes/no to continue volume creation. If there isn't any optimal value for the given number of bricks, a warning is also shown and, if the user accepts, a redundancy of 1 is used. If 'redundancy' is specified and the resulting volume is not optimal, another warning is shown to the user. A distributed-disperse volume can be created using a number of bricks multiple of the disperse count.
