cluster/ec: Fix readdir de-itransform

2015-04-11T09:11:15+00:00

Problem:
gf_deitransform returns the glbal client-id in the complete graph. So except
for the first disperse subvolume under dht, all the other disperse subvolumes
will return a client-id greater than ec->nodes, so readdir will always error
out in those subvolumes.

Fix:
Get the client subvolume whose client-id matches the client-id returned by
gf_deitransform of offset.

tests: prevent regular hangs in ec/nfs.t

2015-03-16T15:41:25+00:00

When the test systems gets into a memory pressure state (the Jenkins VMs
do not have much RAM), the localhost NFS-mount can get hung. It is
possible to prevent this by writing with O_DIRECT. Unfortnately, the
'dd' command on NetBSD does not seem to support such an option.

The alternative is to reduce the I/O that can get cached on the
NFS-client, like reducing the "count" option for "dd".

epoll: Fix broken RPC throttling due to MT epoll

2015-03-02T06:50:07+00:00

The RPC throttle which kicks in by setting the poll-in event on a
socket to false, is broken with the MT epoll commit. This is due
to the event handler of poll-in attempting to read as much out of
the socket till it receives an EAGAIN. Which may never happen and
hence we would be processing far more RPCs that we want to.

This is being fixed by changing the epoll from ET to LT, and
reading request by request, so that we honor the throttle.

The downside is that we do not drain the socket, but go back to
epoll_wait before reading the next request, but when kicking in
throttle, we need to anyway and so a busy connection would degrade
to LT anyway to maintain the throttle. As a result this change
should not cause deviation in the performance much for busy
connections.

Temporarily remove nfs.t to avoid regression failures

2015-02-12T18:42:41+00:00

Test basic/ec/nfs.t is causing many regression failures due to
a problem related with NFS.

While the NFS problem is solved, this patch removes the test
to avoid more regression failures.

cluster/ec: Handle CHILD UP/DOWN in all cases

2015-01-29T03:49:53+00:00

Problem:
When all the bricks are down at the time of mounting the volume, then mount
command hangs.

Fix:
1. Ignore all CHILD_CONNECTING events comming from subvolumes.
2. On timer expiration (without enough up or down childs) send
   CHILD_DOWN.
3. Once enough up or down subvolumes are detected, send the appropriate event.
   When rest of the subvols go up/down without changing the overall
   ec-up/ec-down send CHILD_MODIFIED to parent subvols.

cluster/ec: Handle internal xattr get/set

2015-01-09T05:55:37+00:00

Problem:
Internal xattrs of EC like trusted.ec.size/config/version
can be modified by users and that can lead to misbehavior
in EC.

Fix:
Don't let the user modify the xattrs. Hide these xattrs
in getfattr outputs.

Regression test portability: ec.t

2014-12-17T17:14:07+00:00

This test unmount/remount the filesystem to invalidate cache,
but this leads to timing problems on NetBSD. We can work them
around without sleeping by remounting on another mount point.

Regression tests portability: Do not 'cd' into volume

2014-11-24T18:45:42+00:00

Changing current directory to the root of the volume to
execute tests from there keeps an open file descriptor
to it that could interfere with some tests.

I've removed all 'cd' and used abosulte paths on all
tests.
