* glusterd/ afr: remove the readdir-failover option from rebalance processRavishankar N2015-06-221-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove the "replicate*.readdir-failover=off" xlator option from rebalance process' runner arguments because this is the default behaviour in afr-v2. i.e. reaaddir failover happens only if it is a new readdir (offset=0). 'Continuing'readdirs are always wound on the same child where the first readdir had happened and if that child is down, the readdir fails. The option cannot be removed from glusterd_volopt_map because there is a chance of ending up in peer rejected state in a heterogenous cluster (typical upgrade scenario) due to volinfo checksum mismatch. TODO:come up with some warning message to the user for such deprecated options if a volume set is attempted.

* dht: make lookup-unhashed=auto do something actually usefulJeff Darcy2015-05-091-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* glusterd: CLI commands to create and manage tiered volumes.Dan Lambright2015-03-191-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The liburcu data structes and APIs are a drop-in replacement for libglusterfs lists. All usages have been changed to keep the code consistent, and free from confusion. NOTE: glusterd_conf_t->xprt_list still uses the libglusterfs data structures and API, as it holds rpc_transport_t objects, which is not a part of glusterd and is not being changed in this patch. This change was developed on the git branch at [1].

* glusterd: Handle rpc_connect failure in the event handlerVijaikumar M2014-06-051-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently rpc_connect calls the notification function on failure in the same thread, glusterd notification holds the big_lock and hence big_lock is released before rpc_connect In snapshot creation, releasing the big-lock before completeing operation can cause problem like deadlock or memory corruption. Bricks are started as part of snapshot created operation. brick_start releases the big_lock when doing brick_connect and this might cause glusterd crash. There is a similar issue in bug# 1088355. Solution is let the event handler handle the failure than doing it in the rpc_connect.

* glusterd: Volume locks and transaction specific opinfosAvra Sengupta2014-02-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch we are replacing the existing cluster-wide lock taken on glusterds across the cluster, with volume locks which are also taken on glusterds across the cluster, but are volume specific. So with the volume locks we are able to perform more than one gluster operation at the same time, as long as the operations are being performed on different volumes. We maintain a global list of volume-locks (using a dict for a list) where the key is the volume name, and which saves the uuid of the originator glusterd. These locks are held and released per volume transaction. In order to acheive multiple gluster operations occuring at the same time, we also separate opinfos in the op-state-machine, as a part of this patch. To do so, we generate a unique transaction-id (uuid) per gluster transaction. An opinfo is then associated with this transaction id, which is used throughout the transaction. We maintain a run-time global list(using a dict) of transaction-ids, and their respective opinfos to achieve this.

The format for the new path of the defrag sockfile is 'DEFAULT_VAR_RUN_DIRECTORY/gluster-rebalance-<vol-id>.sock'. This was needed because the earlier location didn't have a fixed length and could exceed UNIX_PATH_MAX characters. This could lead to the rebalance process failing to start as the socket file could not be created. Also, for keeping backward compatiblity, glusterd_rebalance_rpc_create will try both the new and old sockfile locations when attempting reconnection.

* glusterd: big lock - a coarse-grained locking to prevent racesKrishnan Parthasarathi2013-04-121-3/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are primarily three lists that are part of glusterd process, that are concurrently accessed. Namely, priv->volumes, priv->peers and volinfo->bricks_list. Big-lock approach ----------------- WHAT IS IT? Big lock is a coarse-grained lock which protects all three lists, mentioned above, from racy access. HOW DOES IT WORK? At any given point in time, glusterd's thread(s) are in execution _iff_ there is a preceding, inbound network event. Of course, the sigwaiter thread and timer thread are exceptions. A network event is an external trigger to glusterd, via the epoll thread, in the form of POLLIN and POLLERR. As long as we take the big-lock at all such entry points and yield it when we are done, we are guaranteed that all the network events, accessing the global lists, are serialised. This amounts to holding the big lock at - all the handlers of all the actors in glusterd. (POLLIN) - all the cbks in glusterd. (POLLIN) - rpc_notify (DISCONNECT event), if we access/modify one of the three lists. (POLLERR) In the case of synctask'ized volume operations, we must remember that, if we held the big lock for the entire duration of the handler, we may block other non-synctask rpc actors from executing. For eg, volume-start would block in PMAP SIGNIN, if done incorrectly. To prevent this, we need to yield the big lock, when we yield the synctask, and reacquire on waking up of the synctask.

* cluster/dht: Add "afr.readdir-failover=off" option the rebalance processshishir gowda2012-12-161-0/+1
| | | | | | | | | | | | | | | | | By failing over readdir (default behaviour), rebalance could get duplicate files, as readdir would re-read from offset 0. Rebalance should not attempt to migrate these files again. Additionally, we need to handle these cases as failure in rebalance crawl. No test case provided, as we cannot determine the read child in afr.
