* dht: report constant directory sizeJeff Darcy2016-03-284-1/+81
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Directory size is meaningless. Every filesystem has its own unpredictable way of increasing or decreasing it, based on internal data structures and even transient conditions. Some filesystems (e.g. ext4) never decrease it at all. Others (e.g. btrfs) don't even report it. Very few programs look at it, and those that do are broken. Unfortunately, one such program is GNU tar, which will complain when it sees different values because at different times we got the value from different DHT subvolumes. To avoid such problems, just report a constant value.

* dht: update attr information in refresh layout to avoidSakshi Bansal2016-03-281-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | stale timestamp Consider the scenario where an mkdir has just created the directory but has not healed it yet. A parallel lookup on this entry will find anomalies and trigger a selfheal which will sample the ctime of the directory after the mkdir phase. Meanwhile the mkdir has completed setting the layout and updated the ctime. The selfheal then sees the layout to be healed and returns with the ctime it got after the mkdir phase which has now become stale. However if the lookup happens to unwind before the mkdir then the inode associated with lookup will get linked in the inode table which has the stale ctime. To avoid this selfheal must do an iatt_merge in refresh layout to get the latest timestamp irrespective of whether it needs to heal the layout or not.

Once the tar file is untared the files in the tar-file will start to demote. when the demotion is under progress, if we tend to delete the actual folder, then the files under it which are undergoing demotion will do a lookup on the parent which was deleted and become stale entry. This stale entry fails the Lookup and this will fail the demotion of the other files(not from tar) that are supposed to be demoted. >Change-Id: I3d47c32c4077526d477a25912b0135bab98b23fc >BUG: 1311178 >Signed-off-by: hari gowtham <hgowtham@redhat.com> >Reviewed-on: http://review.gluster.org/13501 >Tested-by: hari gowtham <hari.gowtham005@gmail.com> >Smoke: Gluster Build System <jenkins@build.gluster.com> >CentOS-regression: Gluster Build System <jenkins@build.gluster.com> >Reviewed-by: Dan Lambright <dlambrig@redhat.com> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Change-Id: I80a77d149180e2a05b3d7943f370b3ef162e545b BUG: 1317366 Signed-off-by: Hari Gowtham <hgowtham@redhat.com> Reviewed-on: http://review.gluster.org/13692 Smoke: Gluster Build System <jenkins@build.gluster.com> Tested-by: hari gowtham <hari.gowtham005@gmail.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Dan Lambright <dlambrig@redhat.com>

After the old one completes the task, it dies and the status ends up as failed. This patch will check if the status is still running and then let it continue its work.

Ideally, the tier linkto files on the cold tier to files that are hardlinks to each other on the hot tier, should themselves be hardlinks of each other. As they are not, they end up being files with the same gfid but different names for the cold tier dht, and end up overwriting the cached-subvol information stored in the dht inode-ctx. > Change-Id: Ic658a316836e6a1729cfea848b7d212674b0edd2 > BUG: 1305277 > Signed-off-by: N Balachandran <nbalacha@redhat.com> > Reviewed-on: http://review.gluster.org/13391 > 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: Dan Lambright <dlambrig@redhat.com> > Tested-by: Dan Lambright <dlambrig@redhat.com> (cherry picked from commit eb362c74db84d95aac07febf0d888bd98b3fb2b9) Change-Id: I5dd98e6d248619147974a630d7d72e1942a1cc83 BUG: 1311836 Signed-off-by: N Balachandran <nbalacha@redhat.com> Reviewed-on: http://review.gluster.org/13517 Smoke: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: mohammed rafi kc <rkavunga@redhat.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Dan Lambright <dlambrig@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | A query to the database may take a long time if the database has many entries. The tier daemon also sends IPC calls to the bricks which can run slowly, espcially in RHEL6. While it is possible to track down each such instance, the snapshot feature should not be affected by database operations. It requires no migration be underway. Therefore it is okay to pause tiering at any time except when DHT is moving a file. This fix implements this strategy by monitoring when control passes to DHT to migrate a file using the GF_XATTR_FILE_MIGRATE_KEY trigger. If it is not, the pause operation is successful. > Change-Id: I21f168b1bd424077ad5f38cf82f794060a1fabf6 > BUG: 1287842 > Signed-off-by: Dan Lambright <dlambrig@redhat.com> > Reviewed-on: http://review.gluster.org/13104 > Reviewed-by: Joseph Fernandes > Tested-by: Gluster Build System <jenkins@build.gluster.com> Signed-off-by: Dan Lambright <dlambrig@redhat.com> Change-Id: I667e0af24eaa66afefa860c4d73b324e4f39b997 BUG: 1288352 Signed-off-by: Dan Lambright <dlambrig@redhat.com> Reviewed-on: http://review.gluster.org/13199 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | What: If dht_open is called on a migrating file after the inode_ctx is set, subsequent FOPs on that fd do not open the fd on the dst subvol. This is seen when the open-ftruncate-close sequence is repeatedly called on a migrating file. A second call to the sequence described above causes dht_truncate_cbk to call dht_truncate2 as the dht_inode_ctx was already set by the first call. As dht_rebalance_in_progress_check is not called, the fd is not opened on the dst subvol. On a distributed-replicate volume, this causes AFR to open the fd using afr_fix_open, but with the wrong flags, causing posix_ftruncate to fail with EINVAL. The fix: We require fd specific information to make a decision while handling migrating files. Set the fd_ctx to indicate the fd has been opened on the dst subvol and check if it has been set while processing Phase1/Phase2 checks in the FOP callback functions. > Change-Id: I43cdcd8017b4a11e18afdd210469de7cd9a5ef14 > Signed-off-by: N Balachandran <nbalacha@redhat.com> > Reviewed-on: http://review.gluster.org/12985 > Reviewed-by: Raghavendra G <rgowdapp@redhat.com> > Tested-by: Gluster Build System <jenkins@build.gluster.com> > Reviewed-by: Dan Lambright <dlambrig@redhat.com> > Tested-by: Dan Lambright <dlambrig@redhat.com> Change-Id: I99f8aceec105f16631def06a263f0561954d14b3 BUG: 1293827 Signed-off-by: N Balachandran <nbalacha@redhat.com> Reviewed-on: http://review.gluster.org/13071 Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> 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>

All three have been removed from .c files, except those in "contrib" which aren't our problem. Inlines in .h files, which are overwhelmingly "static inline" already, have generally been left alone. Over time we should be able to "lower" these into .c files, but that has to be done in a case-by-case fashion requiring more manual effort. This part was easy to do automatically without (as far as I can tell) any ill effect.

* cluster/tier: do not block in synctask created from pause tierDan Lambright2015-12-253-18/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We had run sleep() in the pause tier callback. Blocking within a synctask is dangerous. The sleep() call does not inform the synctask scheduler that a thread is no longer running. It therefore believes it is running. If a second synctask already exists, it may not be able to run. This occurs if the thread limit in the pool has been reached. Note the pool size only grows when a synctask is created, not when it is moved from wait state to run state, as is the case when an FOP completes. When the tier is paused during migration, synctasks already exist waiting for responses to FOPs to the server with high probability. The fix is to yield() in the RPC callback, which will place the synctask into the wait queue and free up a thread for the FOP callback. A timer wakes the callback after sufficient time has elapsed for the pause to occur.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible a file would get migrated in the middle of a readdir operation. If there are four subvolumes A,B,C,D, and if readdir reads them in order and reaches subvol B, then, if a file is moved from D to A, it will not be included in the readdir output. This phenonema has pre-existed in DHT migration but is more apparent in tiering. When a file is moved off the hashed subvolume a T file is created. For tiering, we will make the cold subvolume the hashed subvolume. This will ensure the creation of a T file. Readdir will not skip T files in the tier translator. Making the cold subvolume the hashed subvolume ensures the T files created on promotions or creates will be less likely to fill the volume. Creates still put the data on the hot subvolume.
