glusterd: add "volume label" command

2012-12-04T22:42:30+00:00

This command is necessary when the local disk/filesystem containing a brick
is unexpectedly lost and then recreated.  Since 961bc80c, trying to start
the brick will fail because the trusted.glusterfs.volume-id xattr is
missing, and if we can't start it then we can't replace-brick or self-heal
so we're stuck in a permanently degraded state.  This command provides a
way to label the empty brick with the proper volume ID so that further
repair actions become possible.

glusterd: Run post hooks on a different thread

2012-05-29T10:16:58+00:00

This change ensures post hooks can 'wait' if need be
and _not_ prevent glusterd from being able to run other operations
meanwhile.

Also ensures that post hook scripts are 'serialized'
between transactions. ie, post hook scripts of txn1 are completed
before post hook scripts of txn2 are started, where txn1 happens before
txn2.

common-utils: Simplified mkdir_p interface and put it to use.

2012-05-21T20:46:18+00:00

- Simplified mkdir_p interface.
- Removed mkdir_if_missing from codebase
- Modified glusterd consumers of mkdir_if_missing to use mkdir_p
  with allow_symlinks=_gf_true. This implicitly assumes that glusterd
  is in 'control' of the brick path and glusterd's working dir in the sense
  that the symlinks (if any) in any of the above mentioned paths are under
  the 'storage administrator's control.

glusterd: Fixed glusterd_brick_create_path algo.

2012-05-16T10:53:52+00:00

- check if any prefix of the brick path has "trusted.gfid"
  or "trusted.glusterfs.volume-id" set.
- set trusted.glusterfs.volume-id on the bricks as soon as
  its induction into the volume is settled. Earlier, the setting of
  "volume-id" used to happen during the first run of the brick process,
  leaving of window for bricks part of one volume to be (ab)used by another
  volume inadvertently.
- removed creation of brick directory (if missing), during start volume force.
  This is to avoid directory creation as part 'force'ful starting of volume
  and leave the responsibility with the user, who understands the
  'availability' of the export directory (brick) better.
