* cluster/distribute: use a linked inode in directory heal codepathRaghavendra G2016-06-062-11/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is needed for following reasons: * healing is done in lookup and mkdir codepath where inode is not linked _yet_ as normally linking is done in interface layers (fuse-bridge, gfapi, nfsv3 etc). * healing consists of non-lookup fops like inodelk, setattr, setxattr etc. All non-lookup fops expect a linked inode.

* posix/lock: implement meta-lock/unlock functionalitySusant Palai2016-06-055-27/+462
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | problem : The lock state needs to be protected when rebalance is reading the lock state on the source. Otherwise there will be locks left unmigrated. Hence, to synchronize incoming lock requests with lock-migration, meta lock is needed. Any new lock request will be queued if there is an active meta-lock and with sucessful lock migration, will be unwound with EREMOTE, so that dht module can wind the request to the correct destination. On a successful lock migration, "pl_inode->migrated" flag is enabled. Hence, any further request would be unwound with EREMOTE and will be redirected to new destination.

In blocking entry lock during rmdir, AFR takes 2 set of locks on all its children-One (parentdir,name of dir to be deleted), the other (full lock on the dir being deleted). We proceed to pre-op stage even if only a single lock (but not all the needed locks) was obtained, only to fail it with ENOTCONN because afr_locked_nodes_get() returns zero nodes in afr_changelog_pre_op(). Fix: After we get replies for all blocking lock requests, if we don't have the minimum number of locks to carry out the FOP, unlock and fail the FOP. The op_errno will be that of the last failed reply we got, i.e. whatever is set in afr_lock_cbk().

* cluster/afr : Do post-op in case of symmetric errorsAnuradha Talur2016-05-241-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of: http://review.gluster.org/#/c/14310/ In afr_changelog_post_op_now(), if there was any error, meaning op_ret < 0, post-op was not being done even when the errors were symmetric and there were no "failed subvols". Fix: When the errors are symmetric, perform post-op. How was the bug found : In a 1 X 3 volume with shard and write behind on when writes were done into a file with one brick down, the trusted.afr.dirty xattr's value for .shard directory would keep increasing as post op was not done but pre-op was. This incorrectly showed .shard to be in split-brain. RCA: When WB is on, due to multiple writes being sent on offset lying in the same shard, chances are that same shard file will be created more than once with the second one failing with op_ret < 0 and op_errno = EEXIST. As op_ret was negative, afr wouldn't do post-op, leading to no decrement of trusted.afr.dirty xattr. Thus showing .shard directory to be in split-brain. >Change-Id: I711bdeaa1397244e6a7790e96f0c84501798fc59 >BUG: 1335652 >Signed-off-by: Anuradha Talur <atalur@redhat.com> Change-Id: I711bdeaa1397244e6a7790e96f0c84501798fc59 BUG: 1335829 Signed-off-by: Anuradha Talur <atalur@redhat.com> Reviewed-on: http://review.gluster.org/14331 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Ravishankar N <ravishankar@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>

* glusterd/geo-rep: slave volume uuid to identify a geo-rep sessionSaravanakumar Arumugam2016-05-234-49/+544
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Currently, it is possible to create multiple geo-rep session from the Master host to Slave host(s), where Slave host(s) belonging to the same volume. For example: Consider Master Host M1 having volume tv1 and Slave volume tv2, which spans across two Slave hosts S1 and S2. Currently, it is possible to create geo-rep session from M1(tv1) to S1(tv2) as well as from M1(tv1) to S2(tv2). When the Slave Host is alone modified, it is identified as a new geo-rep session (as slave host and slave volume together are identifying Slave side). Also, it is possible to create both root and non-root geo-rep session between same Master volume and Slave volume. This should also be avoided. Solution: This multiple geo-rep session creation must be avoided and in order to avoid, use Slave volume uuid to identify a Slave. This way, we can identify whether a session is already created for the same Slave volume and avoid creating again (using different host). When the session creation is forced in the above scenario, rename the existing geo-rep session directory with new Slave Host mentioned.

For eg - if a remove brick is executed with a brick whoose underlying file system has crashed, remove-brick fails since realpath() call fails. We'd need to call realpath() here as the value is of no use.Hence passing construct_realpath as _gf_false in glusterd_volume_brickinfo_get_by_brick () is a must in such cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch does following changes. 1. Introduce scrubber monitor thread. 2. Move scrub status related APIs to separate file and make part of libbitrot library. Problem: Earlier, each child of the scrubber was maintaining the state machine and hence there was no way to track the start and end time of scrubbing as each brick has it's own start and end time. Also each brick was maintaining it's own timer wheel instance. It was also not possible to get scrubbed files count per session as we could not get last child which finishes scrubbing to reset it to zero. Solution: Introduce scrubber monitor thread. It does following. 1. Maintains the scrubber state machine. Earlier each child had it's own state machine. Now, only monitor maintains on behalf of all it's children. 2. Maintains the timer wheel instance. Earlier each child had it's own timer wheel instance. Now, only monitor maintains on behalf of all it's children. As a result, we can track the scrub statistics easily and correctly.

This would lead to situations where failure of clearing the xattr would cause the premature death of migration threads. Now we clear the xattr only after the data movement threads join, ensuring that all migration is done.

* glusterd-ganesha : copy ganesha export configuration files during rebootJiffin Tony Thottan2016-05-185-67/+154
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterd creates export conf file for ganesha using hook script during volume start and ganesha_manage_export() for volume set command. But this routine is not added in glusterd restart scenario. Consider the following case, in a three node cluster a volume got exported via ganesha while one of the node is offline(glusterd is not running). When the node comes back online, that volume is not exported on that node due to the above mentioned issue. Also I have removed unused variables from glusterd_handle_ganesha_op() For this patch to work pcs cluster should running on that be node.

* cluster/afr: Don't let NFS cache stat after writesPranith Kumar K2016-05-147-30/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. >Change-Id: Ic6062acc6e5cdd97a9c83c56bd529ec83cee8a23 >BUG: 1302948 >Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> >Signed-off-by: Anuradha Talur <atalur@redhat.com> >Reviewed-on: http://review.gluster.org/13785 >Smoke: Gluster Build System <jenkins@build.gluster.com> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >CentOS-regression: Gluster Build System <jenkins@build.gluster.com> >Reviewed-by: Niels de Vos <ndevos@redhat.com> BUG: 1335285 Change-Id: Ibef4fc80496d12acd15db57713af2e3a1c9109a7 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/14300 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Ravishankar N <ravishankar@redhat.com> Reviewed-by: Niels de Vos <ndevos@redhat.com>

* readdir-ahead: Prefetch xattrs needed by md-cachePrashanth Pai2016-05-103-7/+204
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Negative cache feature implementation in md-cache requires xattrs returned by posix to be intercepted for every call that can possibly return xattrs. This includes readdirp(). This is crucial to treat missing keys in cache as a case of negative entry (returns ENODATA) md-cache puts names of xattrs that it wants to cache in xdata and passes it down to posix which returns the specified xattrs in the callback. This is done in lookup() and readdirp(). Hence, a xattr that is cached can be invalidated during readdirp_cbk too. This is based on the assumption that readdirp() will always return all xattrs that md-cache is interested in. However, this is not the case when readdirp() call is served from readdir-ahead's cache. readdir-ahead xlator will pre-fetch dentries during opendir_cbk and readdirp. These internal readdirp() calls made by readdir-ahead xlator does not set xdata in it's requests. Hence, no xattrs are fetched and stored in it's internal cache. This causes metadata loss in gluster-swift. md-cache returns ENODATA during getxattr() call even though the xattr for that object exists on the brick. On receiving ENODATA, gluster-swift will create new metadata and do setxattr(). This results in loss of information stored in existing xattr. Fix: During opendir, md-cache will communicate to readdir-ahead asking it to store the names of xattrs it's interested in so that readdir-ahead can fetch those in all subsequent internal readdirp() calls issued by it. This stored names of xattrs is invalidated/updated on the next real readdirp() call issued by application. This readdirp() call will have xdata set correctly by md-cache xlator.

* glusterd: add defence mechanism to avoid brick port clashesPrasanna Kumar Kalever2016-05-103-2/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intro: Currently glusterd maintain the portmap registry which contains ports that are free to use between 49152 - 65535, this registry is initialized once, and updated accordingly as an then when glusterd sees they are been used. Glusterd first checks for a port within the portmap registry and gets a FREE port marked in it, then checks if that port is currently free using a connect() function then passes it to brick process which have to bind on it. Problem: We see that there is a time gap between glusterd checking the port with connect() and brick process actually binding on it. In this time gap it could be so possible that any process would have occupied this port because of which brick will fail to bind and exit. Case 1: To avoid the gluster client process occupying the port supplied by glusterd : we have separated the client port map range with brick port map range more @ http://review.gluster.org/#/c/13998/ Case 2: (Handled by this patch) To avoid the other foreign process occupying the port supplied by glusterd : To handle above situation this patch implements a mechanism to return EADDRINUSE error code to glusterd, upon which a new port is allocated and try to restart the brick process with the newly allocated port. Note: Incase of glusterd restarts i.e. runner_run_nowait() there is no way to handle Case 2, becuase runner_run_nowait() will not wait to get the return/exit code of the executed command (brick process). Hence as of now in such case, we cannot know with what error the brick has failed to connect. This patch also fix the runner_end() to perform some cleanup w.r.t return values.
