glusterd/geo-rep : Allow volume to stop if geo-rep is not active.

2014-01-29T06:47:32+00:00

In staging phase of volume stop, code is added to read the state_file
for each slave of the master to which the volume belongs. If any of the
geo-rep session is active with at least one slave, volume is not
allowed to stop else it is allowed.

mgmt/glusterd: make sure quota enforcer has established connection with quotad before marking quota as enabled.

2014-01-29T06:46:35+00:00

without this patch there is a window of time when quota is marked as
enabled in quota-enforcer, but connection to quotad wouldn't have been
established. Any checklimit done during this period can result in a
failed fop because of unavailability of quotad.

features/quota: Metadata cleanup

2014-01-29T06:39:43+00:00

Quota and marker uses 'trusted.glusterfs.quota*' and 'trusted.pgfid*' xattrs to
store its configurations and accounting information and also to build the
parent inode chain in case of absense of path.

Problem:
After disabling and then enabling quota back, the xattrs may contain stale data
leading to impaired accounting and thus improper enforcement.

Solution:
Clean up all the quota related xattrs after quota disable.

Marker xlator implements a virtual xattr to cleanup quota and pgfid xattrs. In
this approach glusterd mounts an auxiliary mount and sends the below command to
all the files by crawling the mountpoint.

 #setfattr -n "glusterfs.quota-xattr-cleanup" -v 1

2014-01-27T05:40:57+00:00

network traffic (READ and WRITE FOPs).

glusterd: Save/restore/sync rebalance dict

2014-01-03T11:11:04+00:00

A dictionary was added to store additional information of a rebalance
process, like the bricks being removed in case of a rebalance started
by remove-brick. This dictionary wasn't being stored/restored or synced
during volume sync, leading to errors like a volume status command
failing. These issues have been fixed in this patch. The rebalance dict
is now stored/restored and also exported/imported during volume sync.

Also, this makes sure that the rebalance dict is only create on
remove-brick start. This adds a bricks decommissioned status to the
information imported/exported during volume sync.
