replicate: remove checks which prevented self-heal when open fds were present

2010-10-18T10:25:50+00:00

this check is not needed anymore since the introduction of changelog piggybacking
as the optimization technique instead of first-write-to-flush technique

replicate: replace first-write-to-flush optimization

2010-10-18T10:25:46+00:00

use a changelog piggybacking optimization instead of first-write-to-flush
optimization and do other cleanups (removal of post-post-op hook etc.)

cluster/afr: Set lk-owner to pid when fuse does not supply it.

2010-06-29T09:58:04+00:00

Use the frame->root address as lk-owner when FUSE does
not supply lk_owner.

Raghu,
I unit tested this patch with dbench and self heal tests.
Did not observe lk-owner=0 in any server logs. Can you
verify this patch with the other tests you had run today?

cluster/afr: Failover readdir calls.

2010-03-04T10:04:20+00:00

This patch makes the replicate readdir call fail over to the next
subvolume if the first call fails. It takes care to ensure that
entries are not duplicated.

The failover behavior of readdir only comes into effect if
the option 'strict-readdir' is on.

storage/posix: Added janitor thread.

2009-12-02T18:29:23+00:00

The janitor thread deletes all files and directories in
the "/" GF_REPLICATE_TRASH_DIR directory. This directory
is used by replicate self-heal to dump files and
directories it deletes.

This is needed because letting replicate walk the directory
tree and delete a directory and all its children is too racy.
Instead, replicate self-heal only does an atomic rename(),
and the janitor thread takes care of actually deleting them.

cluster/afr: Set the self-heal "source" as read subvolume even when not doing self-heal.

2009-12-01T14:30:00+00:00

This patch sets the read-subvolume equal to the self-heal "source"
even if we're not doing self-heal (because some one else is already
doing it).
