Change in vdsm[master]: tests: Add a live merge functional test
by alitke＠redhat.com
Adam Litke has uploaded a new change for review.
Change subject: tests: Add a live merge functional test
......................................................................
tests: Add a live merge functional test
Test whether we can successfully merge the active layer. Uses lots of
the functional test infrastructure! Only runs if vdsm says it can
support live merge.

Change in vdsm[master]: lvm: Exclude faulty devices from lvm long filter
by Nir Soffer
Nir Soffer has uploaded a new change for review.
Change subject: lvm: Exclude faulty devices from lvm long filter
......................................................................
lvm: Exclude faulty devices from lvm long filter
lvm commands use filter to limit access to relevant devices. When the
filter includes a faulty device, lvm commands may block for several
minutes (stuck in D state). We have seen getDevicesList command stuck
for up to 10 minutes because of faulty devices in the long filter.
We used to build the filter from all multipath devices. Now we build the
filter only from devices which have at least one active paths.
# multipath -ll

size=15G features='0' hwhandler='1 emc' wp=rw
|-+- policy='service-time 0' prio=0 status=enabled
| `- 4:0:3:0 sdd 8:48 failed faulty running
`-+- policy='service-time 0' prio=0 status=enabled
`- 4:0:2:0 sdb 8:16 failed faulty running
360060160f4a030003268ab211002e411 dm-1 DGC ,VRAID

| `- 4:0:3:1 sde 8:64 active ready running
`-+- policy='service-time 0' prio=1 status=enabled
`- 4:0:2:1 sdc 8:32 active ready running
Previously, both devices were included in the filter, now only
360060160f4a030003268ab211002e411 will be included in lvm filter.
A faulty device which became active again will be included in lvm filter
after the next refresh (every 5 minutes), or after trying edit or create
a new storage domain.
lvm uses also short filter, including devices used by the certain vg or
lv. It is possible that we also have to exclude such devices from the
short filter. This will be handled later if needed.

Change in vdsm[master]: lvm: Decrease number of retries before failing
by Nir Soffer
Nir Soffer has uploaded a new change for review.
Change subject: lvm: Decrease number of retries before failing
......................................................................
lvm: Decrease number of retries before failing
Previously we configured lvm to stop accessing a device during an lvm
opoeration after 3 errors. This can cause lvm to block 3 times when
trying to access inaccessible device. With current iscsi settings, each
block can be 120 seconds, total 360 seconds. We have seen lvm block for
couple of minutes in such cases.
The retries seems uneeded when working with multiple paths, as multipath
already retry all available paths after SCSI errors on one path. However
when working with single path, multipath should fail after one try.
According to lvm developer this may decrease the time lvm is blocked
when devices are not accesible.
(Not tested yet)

Change in vdsm[master]: clusterlock: Remove uneeded workaround
by Nir Soffer
Nir Soffer has uploaded a new change for review.
Change subject: clusterlock: Remove uneeded workaround
......................................................................
clusterlock: Remove uneeded workaround
Sanlock version XXXX had a off-by-one bug when calling get_hosts with a
host id, returning info for the next host. This bug is fixed in version
XXX. Now we can use the hostId parameter, making the call more efficient
and simpligying clusterlock code.

Change in vdsm[master]: hsm: prepareForShutdown - operations order
by laravot＠redhat.com
Liron Aravot has uploaded a new change for review.
Change subject: hsm: prepareForShutdown - operations order
......................................................................
hsm: prepareForShutdown - operations order
Currently cleanupMasterMount() is executed before
taskMgr.prepareForShutdown() and before the domain monitor is stopped,
that causes to errors during the tasks abortion (becasue of failure to
access the path) and to erros when stopping the domain monitoring
thread on that domain.
The solution introduced in that patch is to change the order of the
operations - so that the cleanupMasterMount() will be executed only
after the other operations are executed.
