scripts: invalid test(1) in extras/S32gluster_enable_shared_storage.sh

2017-08-02T15:10:47+00:00

test(1) man pages says -eq is for INTEGER compares, and = is for
string compares.

Also note the comment that -a and -o are ambiguous and to use
test && test or test || test instead.

This bug has existed since 2015! (yikes)

Found while testing localtime logging and running glusterd in the
foreground.

extras: Turn eager-lock off for gluster-block

2017-08-02T15:02:43+00:00

With the current implementation of eager-lock FINODELK is taking so much
time that cassandra workload times out and errors out. AFR eager-locking
needs to be changed similar to EC eager-locking to make things work
as expected. In the interim, it is better to turn it off

This is how the profile looks if eager-lock is turned on:

extras: Disable remote-dio in gluster-block profile

2017-07-31T16:29:58+00:00

gluster-block file is opened with O_DIRECT but because block-profile has
remote-dio enabled, it is leading to high latency for fsync which leads to
failures in cassandra. Disabling remote-dio fixed this issue. We need to change
remote-dio to disabled in gluster-block.

group-gluster-block: Set default shard-block-size to 64MB

2017-07-31T16:29:09+00:00

With 4MB shard size I/O slows down more because of the extra
inodelk/xattrops in replicate. So increasing it to 64MB which
gave better performance than 4MB.

To simulate writes on a preallocated VM-image, fallocate the file and then do
dd with notrunc
do "fallocate -l 1GB" then "dd if=/dev/zero of=file-1GB bs=1MB count=1024 conv=notrunc"

These are the results on my laptop for dd:

systemd/glusterfssharedstorage : remove dependency for var-run-gluster-shared_storage

2017-07-17T11:41:00+00:00

Currently the script used by glusterfssharedstorage have dependency over
var-run-gluster-shared_storage. But this service will be present only if
node has rebooted. Also in reboot scenario , there is a chance that this
service can be executed before creating var-run-gluster-shared_storage.
In that case glusterfssharedstorage will get succeed even without mounting
the shared storage

Also the type of glusterfssharedstorage changed to "forking" so that it can
be active(instead of dead) after the successful start.

In the internal testing that was done, stat-prefetch did help
reduce the number of stats coming from qemu hitting the disk,
and thereby improved performance.

Scripts to identify quota accouting issues

2017-06-30T08:39:05+00:00

The patch contains 2 scripts:

log_accounting.sh does a du -h on the FS hierarchy and a quota list
on the hierarchy and interleaves the two output. We can then identify
which directory(s) in FS has caused the accounting to go bad and try
to investigate what fops happened on those directories. We can also
limit the set of directories on which we need to set dirty xattr to
correct accounting.
xattr_analysis.py reads all the xattr of a brick and dumps it a human
readable form to ease debugging.

glusterd.service (systemd), shows "Active failed" when gd in stop state

2017-06-19T16:06:01+00:00

While doing cleanupandexit glusterd was handling the signal SIGTERM which
is clean exit but systemd treats it as failure being a non-zero value.

With this fix dependency "SuccessExitStatus " has been added
in glusterd.service which takes care of service stop properly.
