* features/index: Delete parent dir indices when heal on it is completeKrutika Dhananjay2016-06-282-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | In this patch, the state information about whether a directory gfid index is present or not is stored in the inode ctx with values IN and NOTIN. This saves index xl the need to perform stat() everytime an index_entry_create() is called. When a brick is restarted these in-memory inode ctx records will be gone. So when granular entry heal happens after a brick is restarted, and a post-op is done on the parent, if the state gotten from inode ctx is UNKNOWN, then index xl does a stat to initialize the state as IN or NOTIN. Note that this is a one-time operation for the lifetime of the brick. Such a change also helps avoid calling index_del() in xattrop_index_action() periodically even when granular self-heal is disabled or when the volume type is disperse.

* cli: fix crash in arbiter keyword parsingRavishankar N2016-06-171-0/+25
| | | | | | | | | | | | | | | | | | | A negative case like `gluster volume create volname arbiter 3 /bricks{1..3}` must not crash. 'arbiter' keyword is valid only for (3 way) replica volumes. The .t that is added will crash and create a core *without* the fix when run but will still pass all TESTs. Since the regression framework fails the .t if it creates a core, we can consider it a valid test 'that fails without the fix'.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1.Provide a command to convert replica 2 volumes to arbiter volumes. Existing self-heal logic will automatically heal the file hierarchy into the arbiter brick, the progress of which can be monitored using the heal info command. Syntax: gluster volume add-brick <VOLNAME> replica 3 arbiter 1 <HOST:arbiter-brick-path> 2. Add checks when removing bricks from arbiter volumes: - When converting from arbiter to replica 2 volume, allow only arbiter brick to be removed. - When converting from arbiter to plain distribute volume, allow only if arbiter is one of the bricks that is removed. 3. Some clean-up: - Use GD_MSG_DICT_GET_SUCCESS instead of GD_MSG_DICT_GET_FAILED to log messages that are not failures. - Remove unused variable `brick_list` - Move 'brickinfo->group' related functions to glusted-utils.

* cluster/afr: Don't let NFS cache stat after writesPranith Kumar K2016-05-041-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | Problem: Afr does post-ops after write but the stat buffer it unwinds is at the time of write, so if nfs client caches this, it will see different ctime when it does stat on it after post-op is done. From NFS client's perspective it thinks the file is changed. Tar which depends on this to be correct keeps giving 'file changed as we read it' warning. If Afr instead has to choose to unwind after post-op, eager-lock, delayed-post-op will have to be disabled which will lead to bad performance for all write usecases. Fix: Don't let client cache stat after write.

* cluster/afr: Fix spurious entries in heal infoPranith Kumar K2016-04-201-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Locking schemes in afr-v1 were locking the directory/file completely during self-heal. Newer schemes of locking don't require Full directory, file locking. But afr-v2 still has compatibility code to work-well with older clients, where in entry-self-heal it takes a lock on a special 256 character name which can't be created on the fs. Similarly for data self-heal there used to be a lock on (LLONG_MAX-2, 1). Old locking scheme requires heal info to take sh-domain locks before examining heal-state. If it doesn't take sh-domain locks, then there is a possibility of heal-info hanging till self-heal completes because of compatibility locks. But the problem with heal-info taking sh-domain locks is that if two heal-info or shd, heal-info try to inspect heal state in parallel using trylocks on sh-domain, there is a possibility that both of them assuming a heal is in progress. This was leading to spurious entries being shown in heal-info. Fix: As long as there is afr-v1 way of locking, we can't fix this problem with simple solutions. If we know that the cluster is running newer versions of locking schemes, in those cases we can give accurate information in heal-info. So introduce a new option called 'locking-scheme' which if it is 'granular' will give correct information in heal-info. Not only that, Extra network hops for taking compatibility locks, sh-domain locks in heal info will not be necessary anymore. Thus it improves performance.

| | | | | | | | | | | | | | | | | | | | | | | Problem: In afr-v1 pre-op, xattrop increments self xattr first then it increments the value on rest. In post-op, xattr value is decreased first on rest and at last it gets decremented on self. So for a possible operation to be witnessed i.e. a fop is seen by the brick it is important to have at least 1 pending op because without completing pre-op fop won't come. The other possibility is when fop completes but at the time of post-op after decrementing pending counts on others just before decrementing its own pending count, the brick dies.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: If afr_lookup_done() or afr_read_subvol_select_by_policy() chooses the arbiter brick to serve the stat() data, file size will be reported as zero from the mount, despite other data bricks being available. This can break programs like tar which use the stat info to decide how much to read. Fix: In the inode-context, mark arbiter as a non-readable subvol for both data and metadata. It it to be noted that by making this fix, we are *not* going to serve metadata FOPS anymore from the arbiter brick despite the brick storing the metadata. It makes sense to do this because the ever increasing over-loaded FOPs (getxattr returning stat data etc.) and compound FOPS in gluster will otherwise make it difficult to add checks in code to handle corner cases.

* cli/ afr: op_ret for index heal launchRavishankar N2016-02-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: If index heal is launched when some of the bricks are down, glustershd of that node sends a -1 op_ret to glusterd which eventually propagates it to the CLI. Also, glusterd sometimes sends an err_str and sometimes not (depending on the failure happening in the brick-op phase or commit-op phase). So the message that gets displayed varies in each case: "Launching heal operation to perform index self heal on volume testvol has been unsuccessful" (OR) "Commit failed on <host>. Please check log file for details." Fix: 1. Modify afr_xl_op() to return -1 even if index healing of atleast one brick fails. 2. Ignore glusterd's error string in gf_cli_heal_volume_cbk and print a more meaningful message. The patch also fixes a bug in glusterfs_handle_translator_op() where if we encounter an error in notify of one xlator, we break out of the loop instead of sending the notify to other xlators.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Avoid hangs on unmounting NFS on NetBSD NetBSD umount(8) on a NFS mount whose server is gone will wait forever because umount(8) calls realpath(3) and tries to access the mount before it calls unmount(2). The non-portable, NetBSD-specific umount -R flag prevent that behavior. We therefore introduce UMOUNT_F, defined as "umount -f" on Linux and "umount -f -R" on NetBSD to take care of forced unmounts, especially in the NFS case. 2) Enforce usage of force_umount wrapper with timeout Whenever umount is used it should be wrapped in force_umount with tiemout handling. That saves us timing issues, and it handles the NetBSD NFS case. 3) Cleanup kernel cache flush. We used (cd $M0 && umount $M0 ) as a portable kernel cache flush trick, but it does not flush everything we need on Linux. Introduce a drop_cache() shell function that reverts to previously used echo 3 > /proc/sys/vm/drop_caches on Linux, and keeps (cd $M0 && umount $M0 ) on other systems.

Now heals are triggered from the mount as part of inode refresh. And because the AFR on the mount graph a. does not treat presence of dirty xattrs as something that needs a heal (this is true for dirs fool_heal and fool_me) and b. does not recursively heal the entire hierarchy of subdirs and their entries in one shot (this is true with source_creations_heal/dir1), index heal is used to heal fool_heal, fool_me and source_creations_heal/dir1 wherein only one brick (which is the brick that contains the good copy of source_creations_heal/dir_1: brick-1) has all the gfids to be healed copied into its indices/xattrop directory.
