* cluster/dht: unwind if dht_selfheal_dir_mkdir returns an errorRaghavendra G2018-05-031-1/+5
| | | | | | | | | | If dht_selfheal_dir_mkdir returns an error, cbk passed to dht_selfheal_directory is not invoked. So, Current codepath leaves an unwound frame resulting in a hung fop forever.

* fuse: do fd_resolve in fuse_getattr if fd is receivedSusant Palai2018-04-181-2/+2
| | | | | | | | | | | | | | | | | | | | problem: With the current code, post graph switch the old fd is received for fuse_getattr and since it is associated with old inode, it does not have the inode ctx across xlators in new graph. Hence, dht errored out saying "no layout" for fstat call. Hence the EINVAL. Solution: if fd is passed, init and resolve fd to carry on getattr test case: - Created a single brick distributed volume - Started untar - Added a new-brick Without this fix, untar used to abort with ERROR.

* cluster/dht: Handle file migrations when brick downN Balachandran2018-04-131-5/+51
| | | | | | | | | | | | | | | The decision as to which node would migrate a file was based on the gfid of the file. Files were divided among the nodes for the replica/disperse set. However, if a brick was down when rebalance started, the nodeuuids would be saved as NULL and a set of files would not be migrated. Now, if the nodeuuid is NULL, the first non-null entry in the set is the node responsible for migrating the file.

* cluster/dht: Update layout in inode only on successN Balachandran2018-04-022-4/+24
| | | | | | | | | | | | | | | | | | | | | With lookup-optimize enabled, gf_defrag_settle_hash in rebalance sometimes flips the on-disk layout on volume root post the migration of all files in the directory. This is sometimes seen when attempting to fix the layout of a directory multiple times before calling gf_defrag_settle_hash. dht_fix_layout_of_directory generates a new layout in memory but updates it in the inode ctx before it is set on disk. The layout may be different the second time around due to dht_selfheal_layout_maximize_overlap. If the layout is then not written to the disk, the inode now contains the wrong layout. gf_defrag_settle_hash does not check the correctness of the layout in the inode before updating the commit-hash and writing it to the disk thus changing the layout of the directory.

* Quota: heal directory on newly added bricks when quota limit is reachedSanoj Unnikrishnan2018-03-281-1/+16
| | | | | | | | | | | | | | | | | Problem: if a lookup is done on a newly added brick for a path on which limit has been reached, the lookup fails to heal the directory tree due to quota. Solution: Tag the lookup as an internal fop and ignore it in quota. Since marking internal fop does not usually give enough contextual information. Introducing new flags to pass the contextual info. Adding dict_check_flag and dict_set_flag to aid flag operations. A flag is a single bit in a bit array (currently limited to 256 bits).

* cluster/dht: Handle single dht child in dht_lookupN Balachandran2018-02-221-0/+13
| | | | | | | | | | | | | | | This patch limits itself to only handling the case where no file (data or linkto) exists on the subvol. Additional cases to be handled: 1. A linkto file was found on the only child subvol. This currently calls dht_lookup_everywhere which eventually deletes it. It can be deleted directly as it will not be pointing to a valid subvol. 2. Directory lookups - locking might be unnecessary in some cases. Change-Id: I940ba34531f2aaee1d36fd9ca45ecfd46be662a4 BUG: 1546620 Signed-off-by: N Balachandran <nbalacha@redhat.com>

* cluster/dht: avoid overwriting client writes during migrationSusant Palai2018-02-024-12/+138
| | | | | | | | | | | | | | | | | | | | | | | | For more details on this issue see https://github.com/gluster/glusterfs/issues/308 Solution: This is a restrictive solution where a file will not be migrated if a client writes to it during the migration. This does not check if the writes from the rebalance and the client actually do overlap. If dht_writev_cbk finds that the file is being migrated (PHASE1) it will set an xattr on the destination file indicating the file was updated by a non-rebalance client. Rebalance checks if any other client has written to the dst file and aborts the file migration if it finds the xattr. updates gluster/glusterfs#308 Change-Id: I73aec28bc9dbb8da57c7425ec88c6b6af0fbc9dd Signed-off-by: Susant Palai <spalai@redhat.com> Signed-off-by: Raghavendra G <rgowdapp@redhat.com> Signed-off-by: N Balachandran <nbalacha@redhat.com>

Using percentages instead of absolute available space for space checks can mitigate that to some extent.

* cluster/dht: Serialize mds update code path with lookup unwind in selfhealMohit Agrawal2017-11-223-306/+216
| | | | | | | | | | | | | | | | Problem: Sometime test case ./tests/bugs/bug-1371806_1.t is failing on centos due to race condition between fresh lookup and setxattr fop. Solution: In selfheal code path we do save mds on inode_ctx, it was not serialize with lookup unwind. Due to this behavior after lookup unwind if mds is not saved on inode_ctx and if any subsequent setxattr fop call it has failed with ENOENT because no mds has found on inode ctx.To resolve it save mds on inode ctx has been serialize with lookup unwind.

* cluster/dht: Don't set ACLs on linkto fileN Balachandran2017-11-191-0/+11
| | | | | | | | | | | | | | The trusted.SGI_ACL_FILE appears to set posix ACLs on the linkto file that is a target of file migration. This can mess up file permissions and cause linkto identification to fail. Now we remove all ACL xattrs from the results of the listxattr call on the source before setting them on the target.
