* features/locks: error-out {inode,entry}lk fops with all-zero lk-ownerPranith Kumar K2019-04-165-15/+53
| | | | | | | | | | | | | | | | | Problem: Sometimes we find that developers forget to assign lk-owner for an inodelk/entrylk/lk before writing code to wind these fops. locks xlator at the moment allows this operation. This leads to multiple threads in the same client being able to get locks on the inode because lk-owner is same and transport is same. So isolation with locks can't be achieved. Fix: Disallow locks with lk-owner zero. fixes bz#1624701 Change-Id: I1c816280cffd150ebb392e3dcd4d21007cdd767f Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>
* glusterd: Optimize glusterd handshaking code pathMohit Agrawal2019-04-156-48/+359
| | | | | | | | | | | | | | | | | | | | Problem: At the time of handshaking glusterd populate volume data in a dictionary.While no. of volumes are configured more than 1500 glusterd takes more than 10 min to generated the data.Due to taking more time rpc request times out and rpc start bailing of call frames. Solution: To optimize the code done below changes 1) Spawn multiple threads to populate volumes data in bulk in separate dictionary and introduce an option glusterd.brick-dict-thread-count to configure no. of threads to populate volume data. 2) Populate tier data only while volume type is tier 3) Compare snap data only while snap_count is non zero Fixes: bz#1699339 Change-Id: I38dc71970c049217f9d1a06fc0aaf4c26eab18f5 Signed-off-by: Mohit Agrawal <moagrawal@redhat.com>
* libgfchangelog : use find_library to locate shared librarySunny Kumar2019-04-153-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: libgfchangelog.so: cannot open shared object file Due to hardcoded shared library name runtime loader looks for particular version of a shared library.

* cluster/afr: Remove local from owners_list on failure of lock-acquisitionPranith Kumar K2019-04-155-18/+61
| | | | | | | | | | | | | When eager-lock lock acquisition fails because of say network failures, the local is not being removed from owners_list, this leads to accumulation of waiting frames and the application will hang because the waiting frames are under the assumption that another transaction is in the process of acquiring lock because owner-list is not empty. Handled this case as well in this patch. Added asserts to make it easier to find these problems in future. fixes bz#1696599 Change-Id: I3101393265e9827755725b1f2d94a93d8709e923 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>

Solution: 1) Change per xlator log-level only if brick_mux is enabled.To make sure about brick multiplex introudce a flag brick_mux at ctx->cmd_args. Note: There are two other changes done with this patch 1) Ignore client-log-level option to attach a brick with already running brick if brick_mux is enabled 2) Add a log to print pid of the running process to make easier debugging Change-Id: I39e85de778e150d0685cd9a79425ce8b4783f9c9 Signed-off-by: Mohit Agrawal <moagrawal@redhat.com> Fixes: bz#1696046

| | | | | | | | | | | | | It was written just before fill_void() call. Note that there was a possible overflow if the hostname was too long (unrelated to this patch), but it is now also fixed, as we use a smaller buffer for the hostname. This, in turn, forces us to check if gethostname() failed and add explicitly the terminating null to it.

* core: Brick is not able to detach successfully in brick_mux environmentMohit Agrawal2019-04-142-0/+34
| | | | | | | | | | | | | | | | | | | | | Problem: In brick_mux environment, while volumes are stopped in a loop bricks are not detached successfully. Brick's are not detached because xprtrefcnt has not become 0 for detached brick. At the time of initiating brick detach process server_notify saves xprtrefcnt on detach brick and once counter has become 0 then server_rpc_notify spawn a server_graph_janitor_threads for cleanup brick resources.xprtrefcnt has not become 0 because socket framework is not working due to assigning 0 as a fd for socket. In commit dc25d2c1eeace91669052e3cecc083896e7329b2 there was a change in changelog fini to close htime_fd if htime_fd is not negative, by default htime_fd is 0 so it close 0 also.

| | | | | | | | | | | | | | | | | | When a gluster node in trusted storage pool has failed due to hardware issues, volume delete operation fails saying "Not all peers are up" and peer detach for failed node fails saying "Brick(s) with peer <peer_ip> exists in cluster". The idea here is to use either replace-brick or remove-brick command to remove all the bricks hosted by failed node and then re-attempting the peer detach. This change adds this trick in peer detach error message. fixes: bz#1697866 Change-Id: I0c58887479d31db603ad8d6535ea9d547880ccc8 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>
* core: only log seek errors if SEEK_HOLE/SEEK_DATA is availableNiels de Vos2019-04-111-0/+4
| | | | | | | | | | | | | | | | | | | On RHEL-6 there is no support for SEEK_HOLE/SEEK_DATA and this causes the POSIX xlator to return errno=EINVAL. Because of this, the rpc-server xlator will log all 'failed' seek attempts. When applications call seek() often, the brick logs can grow very quickly and fill up the disks. Messages that get logged are like [server-rpc-fops.c:2091:server_seek_cbk] 0-vol01-server: 4947: SEEK-2 (53920aee-062c-4598-aa50-2b4d7821b204), client: worker.example.com-7808-2019/02/08-18:04:57:903430-vol01-client-0-0-0, error-xlator: vol01-posix [Invalid argument] The problem can be reproduced by running a Gluster Server on RHEL-6, with a client running on RHEL-7. The client should execute an application that calls lseek() with SEEK_HOLE/SEEK_DATA.

* client/fini: return fini after rpc cleanupMohammed Rafi KC2019-04-112-6/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | There is a race condition in rpc_transport later and client fini. Sequence of events to happen the race condition 1) When we want to destroy a graph, we send a parent down event first 2) Once parent down received on a client xlator, we will initiates a rpc disconnect 3) This will in turn generates a child down event. 4) When we process child down, we first do fini for Every xlator 5) On successful return of fini, we delete the graph Here after the step 5, there is a chance that the fini on client might not be finished. Because an rpc_tranpsort ref can race with the above sequence. So we have to wait till all rpc's are successfully freed before returning the fini from client Change-Id: I20145662d71fb837e448a4d3210d1fcb2855f2d4 fixes: bz#1659708 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com>

* tests: correctly check open fd's when gfid is missingXavi Hernandez2019-04-101-0/+3
| | | | | | | | | | | | | | | | | The helper funcion get_fd_count() returns how many open fd's has a given gfid on a brick. It could happen that the brick doesn't have information about that inode because it has not been previously accessed. Before this patch, the function returned "" when the inode was not present. This caused basic/ec/ec-fix-openfd.t test to fail because it was expecting '0' as the result. This patch forces get_fd_count() to return '0' when the gfid is not present in the state dump.

| | | | | | | | | | | | | | For testing the recovery of bad (or corrupted files) in a dispersed volume, first enable self-heal daemon and let heal happen.

Hence turn on self-heal daemon and allow the heal to happen after removing corrupted copy from the backend.

* cluster/ec: Fix handling of heal info cases without locksAshish Pandey2019-04-041-25/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we use heal info command, it takes lot of time as in some cases it takes lock on entries to find out if the entry actually needs heal or not. There are some cases where we can avoid these locks and can conclude if the entry needs heal or not. 1 - We do a lookup (without lock) on an entry, which we found in .glusterfs/indices/xattrop, and find that lock count is zero. Now if the file contains dirty bit set on all or any brick, we can say that this entry needs heal. 2 - If the lock count is one and dirty is greater than 1, then it also means that some fop had left the dirty bit set which made the dirty count of current fop (which has taken lock) more than one. At this point also we can definitely say that this entry needs heal. This patch is modifying code to take into consideration above two points. It is also changing code to not to call ec_heal_inspect if ec_heal_do was called from client side heal. Client side heal triggeres heal only when it is sure that it requires heal.

* rpclib: slow floating point math and libmKaleb S. KEITHLEY2019-04-032-9/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In release-6 rpc/rpc-lib (libgfrpc) added the function get_rightmost_set_bit() which calls log2(3), a call that takes a floating point parameter. It's used thusly: right_most_unset_bit = get_rightmost_set_bit(...); (So is it really the right-most unset bit, or the right-most set bit?) It's unclear to me whether this is in the data path or not. If it is, it's rather scary to think about integer-to-float conversions and slow calls to libm functions in the data path. gcc and clang have __builtin_ctz() which returns the same result as get_rightmost_set_bit(), and does it substantially faster. Approx 20M iterations of get_rightmost_set_bit() took ~33sec of wall clock time on my devel machine, while 20M iterations of __builtin_ctz() took < 9sec; get_rightmost_set_bit() is 3x slower than __builtin_ctz(). And as a side benefit, we can again eliminate the need to link libgfrpc with libm. Change-Id: If9e7e80874577c52223f8125b385fc930de20699 updates: bz#1193929 Signed-off-by: Kaleb S.

* cluster/afr: Send inodelk/entrylk with non-zero lk-ownerPranith Kumar K2019-04-022-12/+48
| | | | | | | | | | | | | | Found missing assignment of lk-owner for an inodelk/entrylk before winding the fops. locks xlator at the moment allows this operation. This leads to multiple threads in the same client being able to get locks on the inode because lk-owner is same and transport is same. So isolation with locks can't be achieved. To fix it, we need locks xlator change which will disallow null-lk-owner based inodelk/entrylk/lk. To achieve that we need to first fix all the places which do this mistake. updates bz#1624701 Change-Id: Ic3431da3f451a1414f1f4fdcfc4cf41e555f69dd Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>

* mgmt/shd: Implement multiplexing in self heal daemonMohammed Rafi KC2019-04-0147-294/+2813
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Shd daemon is per node, which means they create a graph with all volumes on it. While this is a great for utilizing resources, it is so good in terms of performance and managebility. Because self-heal daemons doesn't have capability to automatically reconfigure their graphs. So each time when any configurations changes happens to the volumes(replicate/disperse), we need to restart shd to bring the changes into the graph. Because of this all on going heal for all other volumes has to be stopped in the middle, and need to restart all over again. Solution: This changes makes shd as a per volume daemon, so that the graph will be generated for each volumes. When we want to start/reconfigure shd for a volume, we first search for an existing shd running on the node, if there is none, we will start a new process. If already a daemon is running for shd, then we will simply detach a graph for a volume and reatach the updated graph for the volume. This won't touch any of the on going operations for any other volumes on the shd daemon. Example of an shd graph when it is per volume graph ----------------------- | debug-iostat | ----------------------- / | \ / | \ --------- --------- ---------- | AFR-1 | | AFR-2 | | AFR-3 | -------- --------- ---------- A running shd daemon with 3 volumes will be like--> graph ----------------------- | debug-iostat | ----------------------- / | \ / | \ ------------ ------------ ------------ | volume-1 | | volume-2 | | volume-3 | ------------ ------------ ------------ Change-Id: Idcb2698be3eeb95beaac47125565c93370afbd99 fixes: bz#1659708 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com>
* protocol/client: Do not fallback to anon-fd if fd is not openPranith Kumar K2019-03-312-1/+43
| | | | | | | | | | | | | | | | | | If an open comes on a file when a brick is down and after the brick comes up, a fop comes on the fd, client xlator would still wind the fop on anon-fd leading to wrong behavior of the fops in some cases. Example: If lk fop is issued on the fd just after the brick is up in the scenario above, lk fop will be sent on anon-fd instead of failing it on that client xlator. This lock will never be freed upon close of the fd as flush on anon-fd is invalid and is not wound below server xlator. As a fix, failing the fop unless the fd has FALLBACK_TO_ANON_FD flag.
