features/shard: Handle offset in appending writes

2017-05-29T14:12:20+00:00

When a file is opened with append, all writes are appended at the end of file
irrespective of the offset given in the write syscall. This needs to be
considered in shard size update function and also for choosing which shard to
write to.

At the moment shard piggybacks on queuing from write-behind
xlator for ordering of the operations. So if write-behind is disabled and
two parallel appending-writes come both of which can increase the file size
beyond shard-size the file will be corrupted.

extras: Provide group set for gluster-block workloads

2017-05-29T14:12:13+00:00

For gluster-block workloads I/O is always with o-direct so it doesn't
benefit by any of the perf xlators so disabling all of them to save
on memory.
performance.quick-read=off
performance.read-ahead=off
performance.io-cache=off
performance.stat-prefetch=off
performance.write-behind=off
performance.open-behind=off
performance.readdir-ahead=off

We want the I/O on the file to be with o-direct
network.remote-dio=enable

Options that are proven to give good performance with
VM workloads which is very similar to gluster-block
cluster.eager-lock=enable
cluster.quorum-type=auto
cluster.data-self-heal-algorithm=full
cluster.locking-scheme=granular
cluster.shd-max-threads=8
cluster.shd-wait-qlength=10000
features.shard=on

It is better to turn off things we are not using
user.cifs=off

It is better to have allow-insecure to be on so that
ports that are > 1024 in tcmu-runner are allowed.
server.allow-insecure=on

features/bitrot: Fix glusterfsd crash

2017-05-29T13:57:11+00:00

With object versioning being optional, it can
so happen the bitrot stub context is not always
set. When it's not found, it's initialized. But
was not being assigned to use in the local
function. This was leading for brick crash.
Fixed the same.

glusterfsd: process attach and detach request inside lock

2017-05-29T13:56:08+00:00

With brick multiplexing, there is a high possibility that attach and
detach requests might be parallely processed and to avoid a concurrent
update to the same graph list, a mutex lock is required.

Please note this backport defines the volfile_lock mutex which was done
as part of a different patch https://review.gluster.org/15036 in
mainline but is not available in release-3.11 branch.

nl-cache: Remove the max limit for nl-cache-limit and nl-cache-timeout

2017-05-26T16:34:17+00:00

The max limit is better unset when arbitrary. Otherwise in the future
if max has to be changed, it can break backward compatility.
