ovirt 4.2.7.1 fails to deploy hosted engine on GlusterFS
by hunter86_bg＠yahoo.com
Hello Community,
I'm trying to deploy a hosted engine on GlusterFS which fails with the following error:
[ INFO ] TASK [Add glusterfs storage domain]
[ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Failed to fetch Gluster Volume List]". HTTP response code is 400.
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "deprecations": [{"msg": "The 'ovirt_storage_domains' module is being renamed 'ovirt_storage_domain'", "version": 2.8}], "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Failed to fetch Gluster Volume List]\". HTTP response code is 400."}
I have deployed GlusterFS via the HyperConverged Option in Cockpit and the volumes are up and running.

There are no active volume tasks
I'm using the following guide : https://ovirt.org/blog/2018/02/up-and-running-with-ovirt-4-2-and-gluster-...
And on step 4 - Storage - I have defined it as follows:
Storage Type: Gluster
Storage Connection: ovirt1.localdomain:/gluster_bricks/engine/
Mount Options: backup-volfile-servers=ovirt2.localdomain:glarbiter.localdomain
Can someone hint me where is the problem ?

Using the web-ui VM portal through a proxy failing
by Callum Smith
Dear oVirt Gurus,
Using the oVirt user VM portal seems to not work through the squid proxy setup (configured as per the guide). The page loads and login works fine through the proxy, but the asynchronous requests just hang. I've attached a screenshot, but you can see the "api" endpoint just hanging in a web inspector:
"https://proxyfqdn/ovirt-engine/api/"
[cid:CA42E493-3AD9-45F8-B4C3-C914F059390C@well.ox.ac.uk]
This works fine when not going through the proxy.
Is there a way to force noVNC HTML as the console mode through the web-ui, or at least have it as an option if not default?
The console seems not to work when logged in with a base 'user role'.
Regards,
Callum

Hi,
I'm running Version 4.2.3.8-1.el7, and after reboot the engine machine no longer could login into administration portal with this error:
sun.security.validator.ValidatorException: PKIX path validation faile
java.security.cert.CertPathValidatorException: validity check failed
I'm using a self signed cert.
Any idea?
Thanks

Ovirt cluster unstable; gluster to blame (again)
by Jim Kusznir
hi all:
Once again my production ovirt cluster is collapsing in on itself. My
servers are intermittently unavailable or degrading, customers are noticing
and calling in. This seems to be yet another gluster failure that I
haven't been able to pin down.
I posted about this a while ago, but didn't get anywhere (no replies that I
found). The problem started out as a glusterfsd process consuming large
amounts of ram (up to the point where ram and swap were exhausted and the
kernel OOM killer killed off the glusterfsd process). For reasons not
clear to me at this time, that resulted in any VMs running on that host and
that gluster volume to be paused with I/O error (the glusterfs process is
usually unharmed; why it didn't continue I/O with other servers is
confusing to me).
I have 3 servers and a total of 4 gluster volumes (engine, iso, data, and
data-hdd). The first 3 are replica 2+arb; the 4th (data-hdd) is replica
3. The first 3 are backed by an LVM partition (some thin provisioned) on
an SSD; the 4th is on a seagate hybrid disk (hdd + some internal flash for
acceleration). data-hdd is the only thing on the disk. Servers are Dell
R610 with the PERC/6i raid card, with the disks individually passed through
to the OS (no raid enabled).
The above RAM usage issue came from the data-hdd volume. Yesterday, I
cought one of the glusterfsd high ram usage before the OOM-Killer had to
run. I was able to migrate the VMs off the machine and for good measure,
reboot the entire machine (after taking this opportunity to run the
software updates that ovirt said were pending). Upon booting back up, the
necessary volume healing began. However, this time, the healing caused all
three servers to go to very, very high load averages (I saw just under 200
on one server; typically they've been 40-70) with top reporting IO Wait at
7-20%. Network for this volume is a dedicated gig network. According to
bwm-ng, initially the network bandwidth would hit 50MB/s (yes, bytes), but
tailed off to mostly in the kB/s for a while. All machines' load averages
were still 40+ and gluster volume heal data-hdd info reported 5 items
needing healing. Server's were intermittently experiencing IO issues, even
on the 3 gluster volumes that appeared largely unaffected. Even the OS
activities on the hosts itself (logging in, running commands) would often
be very delayed. The ovirt engine was seemingly randomly throwing engine
down / engine up / engine failed notifications. Responsiveness on ANY VM
was horrific most of the time, with random VMs being inaccessible.
I let the gluster heal run overnight. By morning, there were still 5 items
needing healing, all three servers were still experiencing high load, and
servers were still largely unstable.
I've noticed that all of my ovirt outages (and I've had a lot, way more
than is acceptable for a production cluster) have come from gluster. I
still have 3 VMs who's hard disk images have become corrupted by my last
gluster crash that I haven't had time to repair / rebuild yet (I believe
this crash was caused by the OOM issue previously mentioned, but I didn't
know it at the time).
Is gluster really ready for production yet? It seems so unstable to
me.... I'm looking at replacing gluster with a dedicated NFS server likely
FreeNAS. Any suggestions? What is the "right" way to do production
storage on this (3 node cluster)? Can I get this gluster volume stable
enough to get my VMs to run reliably again until I can deploy another
storage solution?

Unable to increase memory or CPU on hosted Engine version 4.2.5.2
by Florian Schmid
Hi,
I'm using version 4.2.5.2 and every article I found, I read that with oVirt 4.2, it should be possible to update CPU and memory for hosted Engine in UI.
Now, when I'm trying to do this, even being on global maintenance, I always get the same error:
Error while executing action:
HostedEngine:
There was an attempt to change Hosted Engine VM values that are locked.
My problem is, that I need to increase the memory, because we had now several times in the last 2 or 3 months an out of memory kill of the java process.
What is the best way to increase memory here? Should I do it over the config file? But how is then the OVF updated?

Hi,
I'm testing backup & restore on Ovirt 4.2.
I follow this doc https://www.ovirt.org/documentation/admin-guide/chap-Backups_and_Migration/
Try to restore to a fresh installation but always get this error message:
restore-permissions
Preparing to restore:
- Unpacking file 'back_file'

Provisioning PostgreSQL users/databases:
- user 'engine', database 'engine'
Restoring:
FATAL: Can't connect to database 'ovirt_engine_history'. Please see '/usr/bin/engine-backup --help'.
On the live engine I run # engine-backup --scope=all --mode=backup --file=file_name --log=log_file_name
And try to restore on a fresh installation:
# engine-backup --mode=restore --file=file_name --log=log_file_name --provision-db --restore-permissions
Any Idea?
Thanks

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
