* performance/io-threads: Provide option to turn off least-priorityPranith Kumar K2012-07-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | RCA: In cases when self-heal is in progress, self-heal fops are starved because of least-priority. This affects other fops with conflicting inode, entry locks with self-heal. Fix: This patch provides configuring enable/disable of least-priority. Additional changes: Moved RCHECKSUM fop to low instead of least because it will still affect the performance of other fops if RCHECKSUM is in LEAST priority. Tests: Tested that the enabling/disabling of fops is working fine. Tested that RCHECKSUM fop priority is assigned LOW when least-priority is disabled.

* cluster/afr: add a new option to select read-subvol by indexJeff Darcy2012-07-031-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | read subvolume is a nice option to set prefred read child if you have a replication over 2 datacenter. if you have 2 datacenter and have a distributed replication where one set of servers are in datacenter one and the other (the replicated) are in the other datacenter read-subvolume it not very handy since it goes over name and the subvolume name is different for each replication pair. i added a new option called read-subvolume-index which take the number of the subvolume to choose. 0 fo first , 1 for second and so on subvolume in every replication. this option can now be used in the --xlator-option mount option to choose the prefered read child for all replication at once. For Example on all clients in datacenter one you can use --xlator-option=volumename-replication-*.read-subvolume-index=0 to prefer read from the servers in datacenter one. when you expand or shrink the volume no changes are needed to the client config since the wildcard will set this option automatic on reconfigure.

* cluster/stripe: implement the coalesce stripe file formatBrian Foster2012-06-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The coalesce file format for cluster/stripe condenses the striped files to a contiguous layout. The elimination of holes in striped files eliminates space wasted via local filesystem preallocation heuristics and significantly improves read performance. Coalesce mode is implemented with a new 'coalesce' xlator option, which is user-configurable and disabled by default. The format of newly created files is marked with a new 'stripe-coalesce' xattr. Cluster/stripe handles/preserves the format of files regardless of the current mode of operation (i.e., a volume can simultaneously consist of coalesced and non-coalesced files). Files without the stripe-coalesce attribute are assumed to have the traditional format to provide backward compatibility. extras/stripe-merge: support traditional and coalesce stripe formats Update the stripe-merge recovery tool to handle the traditional and coalesced file formats. The format of the file is detected automatically (and verified) via the stripe-coalesce attributes.

* replicate: add hashed read-child method.Jeff Darcy2012-05-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both the first-to-respond method and the round-robin method are susceptible to clients repeatedly choosing the same servers across a series of opens, creating hot spots. Also, the code to handle a replica being down will ignore both methods and just choose the first remaining (which is not an issue for two-way but can be otherwise). The hashed method more reliably avoids such hot spots. There are three values/modes. 0: use the old (broken) methods. 1: select a read-child based on a hash of the file's GFID, so all clients will choose the same subvolume for a file (ensuring maximum consistency) but will distribute load for a set of files. 2: select a read-child based on a hash of the file's GFID plus the client's PID, so different children will distribute load even for one file. Mode 2 will probably be optimal for most cases. Using response time when we open the file is problematic, both because a single sample might not have been representative even then and because load might have shifted in the hours or days since (for long-lived files). Trying to use more current load information can lead to "herd following" behavior which is just as bad. Pseudo-random distribution is likely to be the best we can reasonably do, just as it is for DHT.

| | | | | | | | | | | | | | | | | | | | | | | | | | This is the new version of the patch by Kaushik at review.gluster.com/699 The following new option types have been introduced: * GF_OPTION_TYPE_INTERNET_ADDRESS_LIST * GF_OPTION_TYPE_PRIORITY_LIST * GF_OPTION_TYPE_SIZE_LIST and option types of several options in translators have been updated to use the new types. valid_internet_address(), valid_ipv4_address() & valid_ipv6_address() functions has been updated for * wildcard matching. Previously used standalone wildcard address checking functions have been removed. Changes have been done to stripe translator to correctly set, update and use stripe-blocksize. Also minimum value for block-size has been set to 16KB.

In afr, when eager-lock is enabled the inode lock on fd is taken using the fd address as the lk-owner. So the lock is interchangableale between the inode-locks on the same fd.

Linux's default window sizes have been found to be better w.r.t performance, and hence, no more setting it to any default value. However, if one wishes, there's the new configuration option: network.tcp-window-size <sane_size> which takes a size value (int or human readable) and will set the window size of sockets for both clients and servers. Nfs clients will also be updated with the same.

* protocol/client,server: fcntl lock self healing.Mohammed Junaid2012-02-201-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently(with out this patch), on a disconnect the server cleans up the transport which inturn closes the fd's and releases the locks acquired on those fd's by that client. On a reconnect, client just reopens the fd's but doesn't reacquire the locks. The application that had previously acquired the locks still is under the assumption that it is the owner of those locks which might have been granted to other clients(if they request) by the server leading to data corruption. This patch allows the client to reacquire the fcntl locks (held on the fd's) during client-server handshake. * The server identifies the client via process-uuid-xl (which is a combination of uuid and client-protocol name, it is assumed to be unique) and lk-version number. * The client maintains a list of process-uuid-xl, lk-version pair for each accepted connection. On a connect, the server traverses the list for a matching pair, if a matching pair is not found the the server returns lk-version with value 0, else it returns the lk-version it has in store. * On a disconnect, the server and client enter grace period, and on the completion of the grace period, the client bumps up its lk-version number (which means, it will reacquire the locks the next time) and the server will distroy the connection. If reconnection happens within the grace period, the server will find the matching (process-uuid-xl, lk-version) pair in its list which guarantees that the fd's and there corresponding locks are still valid for this client. Configurable options: To set grace-timeout, the following options are option server.grace-timeout value option client.grace-timeout value To enable or disable the lk-heal, option lk-heal [on|off] gluster volume set command can be used to configurable options Change-Id: Id677ef1087b300d649f278b8b2aa0d94eae85ed2 BUG: 795386 Signed-off-by: Mohammed Junaid <junaid@redhat.com> Reviewed-on: http://review.gluster.com/2766 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>

* glusterd: auth allow enhancementsRajesh Amaravathi2012-02-201-21/+121

E.g: volume vol in a cluster of two peers: /mnt/brick1 in 192.168.1.4 /mnt/brick2 in 192.168.1.5 option auth.allow 192.168.1.6 (allow connection requests only from 192.168.1.6) This will disrupt the nfs servers on 192.168.1.{4,5}. brick server processes reject connection requests from both nfs servers (on 4,5), because the peer addresses are not in the auth.allow list. Same holds true for local mounts (on peer machines), self-heal daemon, and other operations which perform a glusterfs mount on one of the peers. * SOLUTION: Login-based authentication (username/password pairs, henceforth referred to as "keys") for gluster services and operations. These *per-volume* keys can be used to by-pass the addr-based authentication, provided none of the peers' addresses are put in the auth.reject list, to enable gluster services like gNfs, self-heal daemon and internal operations on volumes when auth.allow option is exercised. * IMPLEMENTATION: 1. Glusterd generates keys for each volume and stores it in memory as well as in respective volfiles. A new TRUSTED-FUSE volfile is generated which is fuse volfile + keys in protocol/client, and is named trusted-<volname>-fuse.vol. This is used by all local mounts. ANY local mount (on any peer) is granted the trusted-fuse volfile instead of fuse volfile via getspec. non-local mounts are NOT granted the trusted fuse volfile. 2. The keys generated for the volume is written to each server volfile telling servers to allow users with these keys. 3. NFS, self-heal daemon and replace-brick volfiles are updated with the volume's authentication keys. 4. The keys are NOT written to fuse volfiles for obvious reasons. 5. The ownership of volfiles and logfiles is restricted to root users. 6. Merging two identical definitions of peer_info_t in auth/addr and rpc-lib, throwing away the one in auth/addr. 7. Code cleanup in numerous places as appropriate. * IMPORTANT NOTES: 1. One SHOULD NOT put any of the peer addresses in the auth.reject list if one wants any of the glusterd services and features such as gNfs, self-heal, rebalance, geo-rep and quota. 2. If one wants to use username/password based authentication to volumes, one shall append to the server, nfs and shd volfiles, the keys one wants to use for authentication, *while_retaining those_generated_by_glusterd*. See doc/authentication.txt file for details.
