socket: pollerr event shouldn't trigger socket_connnect_finish

2016-09-30T13:27:26+00:00

If connect fails with any other error than EINPROGRESS we cannot get
the error status using getsockopt (... SO_ERROR ... ). Hence we need
to remember the state of connect and take appropriate action in the
event_handler for the same.

As an added note, a event can come where poll_err is HUP and we have
poll_in as well (i.e some status was written to the socket), so for
such cases we need to finish the connect, process the data and then
the poll_err as is the case in the current code.

Special thanks to Kaushal M & Raghavendra G for figuring out the issue.

dht: "replica.split-brain-status" attribute value is not correct

2016-09-27T06:49:45+00:00

Problem: In a distributed-replicate volume attribute
         "replica.split-brain-status" value does not display split-brain
           condition though directory is in split-brain.
         If directory is in split brain on mutiple replica-pairs
         it does not show full list of replica pairs.

Solution: Update the dht_aggregate code to aggregate the xattr
          value in this specific condition.

Fix:      1) function getChoices returns the choices from split-brain
             status string.
          2) function add_opt adding the choices to local buffer to
             store in dictionary
          3) For the key "replica.split-brain-status" function dht_aggregate
             call dht_aggregate_split_brain_xattr to prepare the list.

Test:     To verify the patch followed below steps
          1) Create a distributed replica volume and create mount point
          2) Stop heal daemon
          3) Touch file and directories on mount point
             mkdir test{1..5};touch tmp{1..5}
          4) Down brick process on one of the replica set
             pkill -9 glusterfsd
          5) Change permission of dir on mount point
             chmod 755 test{1..5}
          6) Restart brick process on node with force option
          7) kill brick process on other node in same replica set
          8) Change permission of dir again on mount point
             chmod 766 test{1..5}
          9) Reexecute same step from 4-9 on other replica set also
          10) After check heal status on server it will show dir's are
              in split brain on all replica sets
          11) After check the replica.split-brain-status attr on mount
              point it will show wrong status of split brain.
          12) After apply the patch the attribute shows correct value.

tests: Fix the spurious failure in libgfapi-fini-hang.t

2016-09-21T10:20:13+00:00

RCA:
After running libgfapi-fini-hang, there is a EXPECT_WITHIN which waits
for PROCESS_UP_TIMEOUT(20s), for the process libgfapi-fini-hang to die.
Currently EXPECT_WITHIN is returning success even if the process
libgfapi-fini-hang is alive. This is because "pgrep libgfapi-fini-hang"
in check_process() is returning 1(no process alive) even if the process
is alive. Man page of pgrep says "The process name used for matching is
limited to the 15 characters". Hence changing the name of executable from
libgfapi-fini-hang to gfapi-hang, so that it falls within the limit.

As explained the failure is not because there was a hang(logs show that
glfs_set_volfile_server was still executing), but because EXPECT_WITHIN
was not really waiting. And hence there was a race between the execution
of the process libgfapi-fini-hang and the kill.

cluster/dht: heal root permission post add-brick

2016-09-14T06:33:06+00:00

Post add-brick event the new brick will have permission of 755
by default. If the root directory permission was other than 755,
that does not get healed to the new brick leading to permission
errors/inconsistencies.

For choosing source of attr heal we can trust the subvols which
have layouts with latest ctime(as part of missing directory heal,
we heal the proper attr). In case none of the subvols have layout,
return ESTALE to retrigger a fresh lookup.

Note: This patch heals the permission of the root directories only.
Since, permission healing of directory is not straight forward and
required intrusive fix, those are not addressed here.

cluster/dht: Skip layout overlap maximization on weighted rebalance

2016-09-14T05:20:46+00:00

During a fix-layout, dht_selfheal_layout_maximize_overlap () does not
consider chunk sizes while calculating layout overlaps, causing smaller
bricks to sometimes get larger ranges than larger bricks. Temporarily
enabling this operation if only if weighted rebalance is disabled
or all bricks are the same size.

feature/bitrot: Fix recovery of corrupted hardlink

2016-09-09T14:05:06+00:00

Problem:
When a file with hardlink is corrupted in ec volume,
the recovery steps mentioned was not working.
Only name and metadata was healing but not the data.

Cause:
The bad file marker in the inode context is not removed.
Hence when self heal tries to open the file for data
healing, it fails with EIO.

Background:
The bitrot deletes inode context during forget.

Briefly, the recovery steps involves following steps.
   1. Delete the entry marked with bad file xattr
      from backend. Delete all the hardlinks including
      .glusters hardlink as well.
   2. Access the each hardlink of the file including
      original from the mount.

The step 2 will send lookup to the brick where the files
are deleted from backend and returns with ENOENT. On
ENOENT, server xlator forgets the inode if there are
no dentries associated with it. But in case hardlinks,
the forget won't be called as dentries (other hardlink
files) are associated with the inode. Hence bitrot stube
won't delete it's context failing the data self heal.

Fix:
Bitrot-stub should delete the inode context on getting
ENOENT during lookup.
