cluster/dht: handle EREMOTE in dht lk/flush

2016-05-02T01:05:08+00:00

With lock-migration, we need to send requests to destination
brick post migration. Once, the source brick marks the lock
structure to be already migrated, the requests will be redirected
to destination brick by dht_lk2/flush2.

tier/migrator: Fetch the next query file for the next cycle

2016-04-30T14:30:49+00:00

Problem: When we spawn promote and demote thread, query files
are build. And only query file with index 0 is picked for migration
as the first query file. This may not be suitable for scenarios,
where the file in the query are too big to move in the first cycle,
as a result file in the other query files always get missed. We need to
shuffle so that other query files also get a chance.

Fix: Remember the previous first query file and shift it by one index,
before the migration starts.

dht/afr/client/posix: Fail mkdir without gfid-req

2016-04-29T13:57:39+00:00

Do not allow directory creations without gfids as
after the directories are created, operations
on them fail anyway. So it is better to fail mkdir.

libglusterfs: Add debug and trace logs for stack trace

2016-04-27T19:26:31+00:00

It has become very difficult to identify the xlator which returned
negative op_ret. Being able to just change the log level and
visualize the stack is helpful in such cases.

afr: propagate child up event after timeout

2016-04-27T07:35:19+00:00

Problem: During mount, afr waits for response from all its children before
notifying the parent xlator. In a 1x2 replica volume , if one of the nodes is
down, the mount will hang for more than a minute until child down is received
from the client xlator for that node.

Fix:
When parent up is received by afr, start a 10 second timer. In the timer call
back, if we receive a successful child up from atleast one brick, propagate the
event to the parent xlator.
