Just thinking
Maybe different options where configured to the volumes during update, that
could make them unstable ?
ie: sharding or something else

I don't have ovirt-log-collector on my ovirt engine.  How can obtain?  I see a 
github repo to make file, I do not want to be making files on my ovirt-engine, 
just not yet, I could possible on weekend.


Where can I obtain the ovirt-log-collector?

[ovirt-users] Re: Ovirt Cluster completely unstable

2019-02-15 Thread Ryan Bullock

Just to add, after we updated to 4.3 our gluster just went south.
Thankfully gluster is only secondary storage for us, and our primary
storage is an ISCSI SAN.  We migrated everything over to the SAN that we
could, but a few VM's got corrupted by gluster (data was gone). Right now
we just have gluster off and set to maintenance because the connectivity
issues were causing our main cluster to continuously migrate VMs.

Looking at the gluster hosts themselves I noticed that heal info would
often report one brick down, even if ovirt didn't. Checking the status of
glusterd would also show health checks failed.

Feb  6 15:36:37 vmc3h1 glusterfs-virtstore[17036]: [2019-02-06
23:36:37.937041] M [MSGID: 113075]
[posix-helpers.c:1957:posix_health_check_thread_proc] 0-VirstStore-posix:
health-check failed, going down
Feb  6 15:36:37 vmc3h1 glusterfs-virtstore[17036]: [2019-02-06
23:36:37.937561] M [MSGID: 113075]
[posix-helpers.c:1975:posix_health_check_thread_proc] 0-VirstStore-posix:
still alive! -> SIGTERM

I think the health-check is failing (maybe erroneously) which is then
killing the brick. When this happens it just causing a continuous cycle of
brick up-down and healing, and in turn connectivity issues.

This is our second time running into issues with gluster, so I think we are
going to sideline it for awhile.

2019-02-14 Thread Darryl Scott

I do believe something went wrong after fully updating everything last Friday.  
I updated all the ovirt compute nodes on Friday and gluster/engine on Saturday. 
 I have been experiencing these issues every since.  I have pour over 
engine.log and seems to be connection to storage issue.

with severe GlusterFS problems since the upgrade to new GlusterFS version.  It

Anything in the brick logs..the below logs only indicate that engine
detected that brick was down. To get to why the brick was marked down, the
bricks logs would help

[ovirt-users] Re: Ovirt Cluster completely unstable

2019-02-14 Thread Oliver Riesener


Hi Jayme,

btw. in the past there was  a long hunting for gluster problems on this list.
as resolution, there was a failed single disk drive on one gluster host.
the drive was direct connected without controller and smart checks,
so no alert was generated, only gluster problems over days.

please check you *physical* existents and online status of your gluster drives.

my two cents

Oliver

2019-02-14 Thread Jayme

Oliver,

Thanks for the input, I do recall reading that thread before, I'm 99.9%
sure it's not the problem here but I will double check, if anything to rule
it out.  These bricks are new enterprise SSDs that are less than 3 months
old with almost 0 wear on them and the issues I'm experiencing only started
within hours after upgrading my environment to oVirt 4.3 (and is the same
issue other users are complaining about regarding gluster bricks going
offline after upgrading to 4.3).  I think it's fairly clear that there is a
gluster problem in play.

[ovirt-users] Re: Ovirt Cluster completely unstable

2019-02-14 Thread Jayme

https://bugzilla.redhat.com/show_bug.cgi?id=1677160 doesn't seem relevant
to me?  Is that the correct link?

Like I mentioned in a previous email I'm also having problems with Gluster
bricks going offline since upgrading to oVirt 4.3 yesterday (previously
I've never had a single issue with gluster nor have had a brick ever go
down).  I suspect this will continue to happen daily as some other users on
this group have suggested.  I was able to pull some logs from engine and
gluster from around the time the brick dropped.  My setup is 3 node HCI and
I was previously running the latest 4.2 updates (before upgrading to 4.3).
My hardware is has a lot of overhead and I'm on 10Gbe gluster backend (the
servers were certainly not under any significant amount of load when the
brick went offline).  To recover I had to place the host in maintenance
mode and reboot (although I suspect I could have simply unmounted and
remounted gluster mounts).

tracking the issue on Gluster side on this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1677160
If you can help Gluster community providing requested logs it would be
great.

2019-02-14 Thread Ralf Schenk

Hello,

my problems on gluster started with 4.2.6 or 4.2.7. around end of
September. I still have VM's paused the one or other day an they are
reactivated either by HA oder manually. So i want to testify your
experiences. Even while I'm using bonded network connections there are
communication problems without heavy load or other tasks running.

My new Cluster on EPYC Hardware running on NFS 4.2 storage volumes based
on ZFS runs rock solid and VM's are much faster regarding I/O. Gluster
3.12.5 sucks !

Bye

2019-02-13 Thread Jayme

I have a three node HCI gluster which was previously running 4.2 with zero
problems.  I just upgraded it yesterday.  I ran in to a few bugs right away
with the upgrade process, but aside from that I also discovered other users
with severe GlusterFS problems since the upgrade to new GlusterFS version.
It is less than 24 hours since I upgrade my cluster and I just got a notice
that one of my GlusterFS bricks is offline.  There does appear to be a very
real and serious issue here with the latest updates.

Hi,
I would have a look at engine.log, it might provide usefull informations.
Also, i would test i different storage type (maybe a quick nfs data domain
) and see if problem persist with that one too.
