cluster/dht: Wrong type of function's parameter when calling dht_selfheal_dir_xattr_cbk

2016-06-23T14:33:19+00:00

The second parameter's type is call_frame_t *, and we change
it to be type xlator_t *, it is exactly what we need in this function.

cluster/dht: initialize cbk before attempting inode-link

2016-06-17T12:23:50+00:00

Otherwise inode-link failures in selfheal codepath will result in a
crash.

cluster/dht: Fix unsafe iteration on inode->fd_list

2016-06-15T09:04:29+00:00

When DHT traverses the inode->fd_list, it does that in an unsafe
way that can generate races with fd_unref() called from other threads.

This patch fixes this problem taking the inode->lock and adding a
reference to the fd while it's being used outside of the mutex
protected region.

A minor change in storage/posix has been done to also access the
inode->fd_list in a safe way.

dht/rebalance: mark hardlink failures as skipped in rebalance

2016-05-25T14:19:27+00:00

Since rebalance(not remove-brick) process does not migrate hardlinks
mark them as skipped rather than failed as it creates confusion for
the users.

dht: rename takes lock on parent directory if destination exists

2016-05-18T09:59:25+00:00

For directory rename if destination exists the source directory
is created as a child of the given destination directory. Since
the new child directory does not exist take lock on parent of the
child directory.

cluster/distribute: use a linked inode in directory heal codepath

2016-05-16T16:10:20+00:00

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.
