* mgmt/glusterd: NULL pointer dereferencing clang fixShwetha Acharya2018-10-125-8/+8
| | | | | | | | | | | | | | | Problem: dereferencing of this->name; volinfo and xl can be null. Solution: Replaced this->name with apropriate names in few places, added a null check to avoid dereferencing of volinfo, and introduced a goto out statement, such that null pointer value is not passed to the function volgen_xlator_link when xl becomes NULL.

* afr: prevent winding inodelks twice for arbiter volumesRavishankar N2018-10-101-1/+1
| | | | | | | | | | | | | | | | | | Problem: In an arbiter volume, if there is a pending data heal of a file only on arbiter brick, self-heal takes inodelks twice due to a code-bug but unlocks it only once, leaving behind a stale lock on the brick. This causes the next write to the file to hang. Fix: Fix the code-bug to take lock only once. This bug was introduced master with commit eb472d82a083883335bc494b87ea175ac43471ff Thanks to Pranith Kumar K <pkarampu@redhat.com> for finding the RCA. fixes: bz#1637802 Change-Id: I15ad969e10a6a3c4bd255e2948b6be6dcddc61e1 Signed-off-by: Ravishankar N <ravishankar@redhat.com>

* dht: volume_options 'options' collision with nfs-ganesha's 'options'Kaleb S. KEITHLEY2018-10-044-7/+11
| | | | | | | | | | | | | | | | | When dht was converted to xlator_api, the variable 'options' was not changed to dht_options, the same as was done to all the other xlators that were converted to xlator_api. Thus the reference to 'options' in dht.c is not resolved until runtime, and the RTlinker's search path starts with symbols in the executable, i.e. ganesha.nfsd's 'options'. (Which is obviously not the right one.) The unused extern references to 'options' (now dht_options) in nufa.c and switch.c is curious.

* mgmt/glusterd: use proper path to the volfileRaghavendra Bhat2018-10-043-9/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Till now, glusterd was generating the volfile path for the snapshot volume's bricks like this. /snaps/<snap name>/<brick volfile> But in reality, the path to the brick volfile for a snapshot volume is /snaps/<snap name>/<snap volume name>/<brick volfile> The above workaround was used to distinguish between a mount command used to mount the snapshot volume, and a brick of the snapshot volume, so that based on what is actually happening, glusterd can return the proper volfile (client volfile for the former and the brick volfile for the latter). But, this was causing problems for snapshot restore when brick multiplexing is enabled. Because, with brick multiplexing, it tries to find the volfile and sends GETSPEC rpc call to glusterd using the 2nd style of path i.e. /snaps/<snap name>/<snap volume name>/<brick volfile> So, when the snapshot brick (which is multiplexed) sends a GETSPEC rpc request to glusterd for obtaining the brick volume file, glusterd was returning the client volume file of the snapshot volume instead of the brick volume file.

* glusterd: ignore RPC events when glusterd is shutting downAtin Mukherjee2018-10-041-1/+11
| | | | | | | | | | | | | | | When glusterd receives a SIGTERM while it receives RPC connect/disconnect/destroy events, the thread might lead to a crash while accessing rcu_read_lock () as the clean up thread might have already freed up the resources. This is more observable when glusterd comes up with upgrade mode = on during upgrade process. The solution is to ignore these events if glusterd is already in the middle of cleanup_and_exit ().

They do not need the shebang. A few others are not installed with 'make install', but do have a main() like function. These scripts are expected to be used by developers for different tasks (mostly code generation). Marking these scripts executable to make it easier to identify them.

* fuse: prevent error message "can't shift that many"Niels de Vos2018-10-011-3/+3
| | | | | | | | | | | | | | | | | | | | | | On systems where /bin/sh is not Bash, running plain mount.glusterfs gives the unhelpful error "can't shift that many". The argument parsing can be a little improved. Adding a check for the number of arguments, minimal two (Gluster ip:/volume, and mountpoint), but possibly more (-o, -v etc.). With the additional check, running 'mount.glusterfs -h' now shows the following messags: Usage: /sbin/mount.glusterfs <server>:<volume/subdir> <mountpoint> -o<options> Options: man 8 mount.glusterfs To display the version number of the mount helper: /sbin/mount.glusterfs -V Change-Id: I50e3ade0c6217fab4155f35ad8cb35d99d52e133 Fixes: bz#1564890 Reported-by: Alexander Zimmermann <alexander.zimmermann96@gmail.com> Signed-off-by: Niels de Vos <ndevos@redhat.com>

* glusterd: make sure that brickinfo->uuid is not nullSanju Rakonde2018-09-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: After an upgrade from the version where shared-brick-count option is not present to a version which introduced this option causes issue at the mount point i.e, size of the volume at mount point will be reduced by shared-brick-count value times. Cause: shared-brick-count is equal to the number of bricks that are sharing the file system. gd_set_shared_brick_count() calculates the shared-brick-count value based on uuid of the node and fsid of the brick. https://review.gluster.org/#/c/glusterfs/+/19484 handles setting of fsid properly during an upgrade path. This patch assumed that when the code path is reached, brickinfo->uuid is non-null. But brickinfo->uuid is null for all the bricks, as the uuid is null https://review.gluster.org/#/c/glusterfs/+/19484 couldn't reached the code path to set the fsid for bricks. So, we had fsid as 0 for all bricks, which resulted in gd_set_shared_brick_count() to calculate shared-brick-count in a wrong way. i.e, the logic written in gd_set_shared_brick_count() didn't work as expected since fsid is 0. Solution: Before control reaches the code path written by https://review.gluster.org/#/c/glusterfs/+/19484, adding a check for whether brickinfo->uuid is null and if brickinfo->uuid is having null value, calling glusterd_resolve_brick will set the brickinfo->uuid to a proper value. When we have proper uuid, fsid for the bricks will be set properly and shared-brick-count value will be caluculated correctly. Please take a look at the bug https://bugzilla.redhat.com/show_bug.cgi?id=1632889 for complete RCA Steps followed to test the fix: 1. Created a 2 node cluster, the cluster is running with binary which doesn't have shared-brick-count option 2. Created a 2x(2+1) volume and started it 3. Mouted the volume, checked size of volume using df 4. Upgrade to a version where shared-brick-count is introduced (upgraded the nodes one by one i.e, stop the glusterd, upgrade the node and start the glusterd). 5. after upgrading both the nodes, bumped up the cluster.op-version 6. At mount point, df shows the correct size for volume. fixes: bz#1632889 Change-Id: Ib9f078aafb15e899a01086eae113270657ea916b Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

* glusterd: don't wait for blockers flag for stop volumeAtin Mukherjee2018-09-221-1/+0
| | | | | | | | | | | | | | | With commit 4f6ae8 even though the overall transaction time for gluster volume stop can be reduced, but based on testing it can't be guaranteed that the transaction can finish in 3 minutes before the unlock timer gets kicked in. The ground problem to this is the command serialization which atomic field 'blockers' does for volume stop operation. This patch removes that dependency for volume stop not to wait for blockers.

* afr: fix incorrect reporting of directory split-brainRavishankar N2018-09-217-16/+22
| | | | | | | | | | | | | | | | | Problem: When a directory has dirty xattrs due to failed post-ops or when replace/reset brick is performed, AFR does a conservative merge as expected, but heal-info reports it as split-brain because there are no clear sources. Fix: Modify pending flag to contain information about pending heals and split-brains. For directories, if spit-brain flag is not set,just show them as needing heal and not being in split-brain.

* cluster/afr: Make data eager-lock decision based on number of locksPranith Kumar K2018-09-213-6/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For both Virt and block workloads the file is opened multiple times leading to dynamically setting eager-lock to off for the workload. Instead of depending on the number-of-open-fds, if we change the logic to depend on number of inodelks, then it will give better performance than the earlier logic. When there is an eager-lock and number of inodelks is more than 1 we know that there is a conflicting lock, so depend on that information to decide whether to keep the current transaction go through delayed-post-op or not. Locks xlator doesn't have implementation to query number of locks in fxattrop in releases older than 3.10 so to keep things backward compatible in 3.12, data transactions will use new logic where as fxattrop transactions will use old logic. I am planning to send one more patch which makes metadata domain locks also depend on inodelk-count Profile info for a dd of 500MB to a file with another fd opened on the file using exec 250>filename Without this patch: 0.14 67.41 us 16.72 us 3870.82 us 892 FINODELK 0.59 279.87 us 95.71 us 2085.89 us 898 FXATTROP 3.46 366.43 us 81.75 us 6952.79 us 4000 WRITE 95.79 148733.99 us 50568.12 us 919127.86 us 273 FSYNC With this patch: 0.00 51.01 us 38.07 us 80.16 us 4 FINODELK 0.00 235.43 us 235.43 us 235.43 us 1 TRUNCATE 0.00 125.07 us 56.80 us 193.33 us 2 GETXATTR 0.00 135.86 us 62.13 us 209.59 us 2 INODELK 0.00 197.88 us 155.39 us 253.90 us 4 FXATTROP 0.00 450.59 us 394.28 us 506.89 us 2 XATTROP 0.00 56.96 us 19.06 us 406.59 us 23 FLUSH 37.81 273648.93 us 48.43 us 6017657.05 us 44 LOOKUP 62.18 4951.86 us 93.80 us 1143154.75 us 3999 WRITE postgresql benchmark performance changed from ~1130 TPS to ~2300TPS randio fio job inside Ovirt based VM went from ~600IOPs to ~2000IOPS fixes bz#1630368 Change-Id: If7f7388d2f08cf7f17ca517a4ea222560661dc36 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>
* dht: Operate internal fops with negative pidSusant Palai2018-09-201-0/+1
| | | | | | | | | | | | | | | | | | | With root-squash on, all root credentials are converted to a random uid, gid(65535). And ideally this does not carry the necessary permission bits to carry out the operation. But posix-acl will allow operations from this inode as long as its ctx has the ngroup information and ngroup has the owner group information. The problem we ran into recently was somehow posix-acl xlator did not cache the ngroup info and some of the dht internal fops(layout setxattr) failed with root-squash enabled. DHT internal fops now use a negative pid to pretend that the operation is from an internal client so posix-acl allows them to pass Change-Id: I5bb8d068389bf4c94629d668a16015a95ccb53ab fixes: bz#1624796 Signed-off-by: Susant Palai <spalai@redhat.com>
