tier/glusterd : making new tier detach command throw warning

2015-12-16T17:28:19+00:00

        back port of : http://review.gluster.org/#/c/12883/

For detach tier, the validation was done using the string "detach-tier"
but the new commands used has the string "tier". Making the string use
"tier" to compare, creates problem as the tier status and tier detach
have the keyword "tier". So tier detach and tier status were separated.
and strtok was used to prevent the condition from passing when the
volume name has a substring of "tier". (only the second word from the
string is got and checked if the feature is tier).

Problem: new detach tier command doesnt throw warnings like
"not a tier volume" or " detach tier not started" respectively
instead it prints empty output.

Fix: while validate the volume is checked if its a tiered volume
if yes it is checked if the detach tier is started, else a warning
is thrown respectively.

cluster/tier: add pause tier for snapshots

2015-10-22T02:46:18+00:00

This is a backport of 12304

Snaps of tiered volumes cannot handle files undergoing migration.
We implement a helper mechanism to "pause" migration. Any files
undergoing migration are aborted. Clean up is done to remove
sticky bits and data at the destination. Migration is restarted
after snap completes.

For testing an internal switch is added. It is not exposed externally.

gluster volume set vol1 tier-pause [true|false]

glusterd: support for tier volumes 'detach start' and 'detach commit'

2015-05-09T15:35:14+00:00

        Back port of http://review.gluster.org/10108

These commands work in a manner analagous to rebalancing when removing a
brick. The existing migration daemon detects "detach start" and switches
to moving data off the hot tier. While in this state all lookups are
directed to the cold tier.

gluster v detach-tier  start
gluster v detach-tier  commit

The status and stop cli commands shall be submitted separately.

quota/marker: turn off inode quotas by default

2015-05-08T12:42:20+00:00

inode quota is a new feature implemented in glusterfs-3.7
if quota is enabled in the older version and is upgraded
to a new version, we can hit setxattr spike during self-heal
of inode quotas. So, when a quota is enabled, turn off
inode-quotas with a xlator option.

With this patch, we still account for inode quotas but only
when a write operation is performed for a particular file.
User will be able to query inode quotas once the Inode-quota
xlator option is enabled.
