* cli,glusterd: Changes to cli-glusterd communicationKaushal M2013-10-1710-40/+265
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Glusterd changes: With this patch, glusterd creates a socket file in DATADIR/run/glusterd.socket , and listen on it for cli requests. It listens for 2 rpc programs on the socket file, - The glusterd cli rpc program, for all cli commands - A reduced glusterd handshake program, just for the 'system:: getspec' command The location of the socket file can be changed with the glusterd option 'glusterd-sockfile'. To retain compatibility with the '--remote-host' cli option, glusterd also listens for the cli requests on port 24007. But, for the sake of security, it listens using a reduced cli rpc program on the port. The reduced rpc program only contains read-only procs used for 'volume (info|list|status)', 'peer status' and 'system:: getwd' cli commands. CLI changes: The gluster cli now uses the glusterd socket file for communicating with glusterd by default. A new option '--gluster-sock' has been added to allow specifying the sockfile used to connect. Using the '--remote-host' option will make cli connect to the given host & port. Tests changes: cluster.rc has been modified to make use of socket files and use different log files for each glusterd. Some of the tests using cluster.rc have been fixed.

* dht: dht_lookup_dir_cbk should set op_errno as local->op_errnoKaushal M2013-10-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Two glusterfs clients return inconsistent errnos when the bricks of the volume were down. Consider two gluster mounts. Mount 1 was done when the bricks were online. Mount 2 was done after the bricks were killed, (using the 'glusterfs' command instead of the mount script). For any request, mount 1 will return ENOTCONN, where as mount 2 will return ENOENT. This happens because for the 2nd mount, a fuse would send a lookup on '/' for any request, as it hadn't been done yet. The client xlator returns ENOTCONN, but the dht_lookup_dir_cbk changed this to ENOENT unconditionally when aggregating. So, fuse returned ENOENT, even though the errno should have been ENOTCONN.

* libglusterfs: Add monotonic clocking counter for timer threadHarshavardhana2013-10-1517-61/+154
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gettimeofday() returns the current wall clock time and timezone. Using these functions in order to measure the passage of time (how long an operation took) therefore seems like a no-brainer. This time suffer's from some limitations: a. They have a low resolution: “High-performance” timing by definition, requires clock resolutions into the microseconds or better. b. They can jump forwards and backwards in time: Computer clocks all tick at slightly different rates, which causes the time to drift. Most systems have NTP enabled which periodically adjusts the system clock to keep them in sync with “actual” time. The adjustment can cause the clock to suddenly jump forward (artificially inflating your timing numbers) or jump backwards (causing your timing calculations to go negative or hugely positive). In such cases timer thread could go into an infinite loop. From 'man gettimeofday': ---------- .. .. The time returned by gettimeofday() is affected by discontinuous jumps in the system time (e.g., if the system administrator manually changes the system time). If you need a monotonically increasing clock, see clock_gettime(2). .. .. ---------- Rationale: For calculating interval timing for Timer thread, all that’s needed should be clock as a simple counter that increments at a stable rate. This is necessary to avoid the jumps which are caused by using "wall time", this counter must be monotonic that can never “tick” backwards, ever.

* cluster/afr: [Feature] Command implementation to get heal-countVenkatesh Somyajulu2013-10-1415-60/+1008
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently to know the number of files to be healed, either user has to go to backend and check the number of entries present in indices/xattrop directory. But if a volume consists of large number of bricks, going to each backend and counting the number of entries is a time-taking task. Otherwise user can give gluster volume heal vol-name info command but with this approach if no. of entries are very hugh in the indices/ xattrop directory, it will comsume time. So as a feature, new command is implemented. Command 1: gluster volume heal vn statistics heal-count This command will get the number of entries present in every brick of a volume. The output displays only entries count. Command 2: gluster volume heal vn statistics heal-count replica 192.168.122.1:/home/user/brickname Here if we are concerned with just one replica. So providing any one of the brick of a replica will get the number of entries to be healed for that replica only. Example: Replicate volume with replica count 2. Backend status: -------------- [root@dhcp-0-17 xattrop]# ls -lia | wc -l 1918 NOTE: Out of 1918, 2 entries are <xattrop-gfid> dummy entries so actual no. of entries to be healed are 1916.

* gfapi: object handle based API extensionsR.Shyamsundar2013-10-1115-45/+3230
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is an ongoing effort to integrate NFS Ganesha ( https://github.com/nfs-ganesha/nfs-ganesha/wiki ) with GlusterFS as one of the file system back ends. Towards this we need extensions to gfapi that can handle object based operations. Meaning, instead of using full paths or relative paths from cwd, it is required that we can work with APIs, like the *at POSIX variants, to be able to create, lookup, open etc. files and directories. Hence the objects are the files or directories themselves and we give out handles to these objects that can be used for further operations. This code drop is an initial implementation of the proposed APIs. The new APIs are implemented as glfs_h_XXX variants in the file glfs-handleops.c to mirror glfs-fops.c style. The code leverages holding onto inode references and doling these out as opaque/cookie type objects to the callers, to enable them to be used as handles in other operations. An fd based approach was considered, but due to the extra footprint that the fd structure and its counterparts would incur, this was dropped to take the approach of holding inode references themselves. Tested by extending glfsxmp.c to invoke and exercise the added APIs, and further tested with a reference integration of the same as an FSAL with NFS Ganesha.

If invoked again after initialization (i.e., due to graph changes), the block driver registration code can reinsert entries into bdrv_drivers, effectively corrupting the NULL terminated linked list. This manifests as an infinite loop for callers attempt to traverse the list (to locate a driver).

| | | | | | | | | | | | | | | | | | | oVirt's Gluster Integration needs an inexpensive command that can be executed every 10 seconds to monitor async tasks and their parameters, for all volumes. The solution involves adding a 'tasks' sub-command to 'volume status' to fetch only the async task IDs, type and other relevant parameters. Only the originator glusterd participates in this command as all the information needed is available on all the nodes. This is to make the command suitable for being executed every 10 seconds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In existing georep logrotate was implemented by handling SIGSTOP and SIGCONT, gsyncd was failing to start again after SIGSTOP. New approach uses WatchedFileHandler in logging, which tracks the log file changes or logrotate. Reopens the log file if logrotate is triggered or if same log file is updated from other process. As per python doc: http://docs.python.org/2/library/logging.handlers.html: The WatchedFileHandler class, located in the logging.handlers module, is a FileHandler which watches the file it is logging to. If the file changes, it is closed and reopened using the file name. A file change can happen because of usage of programs such as newsyslog and logrotate which perform log file rotation. This handler, intended for use under Unix/Linux, watches the file to see if it has changed since the last emit. (A file is deemed to have changed if its device or inode have changed.) If the file has changed, the old file stream is closed, and the file opened to get a new stream.

* glusterd: Calculate volume op-versions only on set/resetKaushal M2013-09-293-6/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The volume op-versions are calculated during a volume set/reset, reading a volume from disk and importing a volume during probe or volume sync. The calculation of the volume op-version depends on the clusters op-version as some features are enabled automatically depending on the clusters op-version. We also don't store the volume op-versions persistently and don't export the volume op-versions during sync. Due to this, there can occur cases which will lead to inconsistencies in volumes in different peers. One such case is below, Consider, a cluster made up 3 peers P1, P2 and P3, operating at op-version N. The cluster has two volumes V1 and V2, which have volume op-versions N (since volume op-version cannot be greater than cluster op-version). We have, Cluster-op-version = N V1 op-version = N V2 op-version = N A set operation on V1 causes the clusters op-version to be bumped up to N+1. Assume that there exist some features that are automatically enabled on op-version N+1. The op-version of V2 remains at N as no operation has been performed on it. So, Cluster op-version = N+1 V1 op-version = N+1 V2 op-version = N Now, we probe a new peer P4. On the new peer we will have the following op-versions, Cluster op-version = N+1 V1 op-version = N+1 V2 op-version = N+1 This happens because we don't send volume op-versions during the sync after probe. P4 will freshly calculate the op-version of V2 (assuming features have been auto enabled due to the cluster op-version being N+1) as N+1. Another case is when glusterd on a peer restarts. Assume P3 was restarted, glusterd will recalculate the volume op-versions during the restore state. Again, op-version of V2 will be calculated as N+1 assuming auto enabled features. This will lead to inconsistency in the volume representation in memory and on disk, as glusterd will assume the volume contains auto enabled features, but the volfiles don't contain them as they were not regenrated. These kind of issues can be solved by calculating the volume op-version only when features are enabled and disabled (ie. during volume set/reset), persisting the volume-op-versions and exporting/importing them.
