Re: [ovirt-users] Standalone Gluster Storage

2017-12-13 Thread Artem Tambovskiy 
Hi,

I just updated almost all storage domains with backup-volfile-servers mount
options, the last one remaining is the hosted_storage domain which serves
hosted engine VM. I wonder if this domain also needs to be configured
with  backup-volfile-servers
option? If so how to do this - I can't put this domain on maintenance via
web UI.

Regards,
Artem

 Did you set also the backup-volfile-servers mount option?

Re: [ovirt-users] Standalone Gluster Storage

2017-12-12 Thread Sahina Bose 
The backup-volfile-servers as an additional mount option should handle the
case where one of the servers goes down - storage domain should continue to
be available.
The servers specified for this option can be the servers participating in
your volume. For instance, the set of unique servers from the "gluster
volume info" command.

If even with this mount option, you're facing an issue - please log a bug
with gluster mount logs and vdsm logs.

thanks

 The problem we have is that when we take a gluster node down for
 updates, maintenance etc. the entire storage domain goes offline in oVirt.
 Other gluster clients, that is servers connecting directly to the gluster
 cluster don't seem to notice if one node goes offline.

 Is anyone else using gluster storage in oVirt that is not managed
 within oVirt?

We did use the backup-volfile-servers option but still had trouble.  We
were simply adding all servers in the cluster as backups, is there a best
practice that should be followed?

I did exactly the same mistake with my standalone GlusterFS cluster and now
need to take down all Storage Domains in order to fix this mistake.
Probably, worth to add a few words about this in Installation guide!

[ovirt-users] Standalone Gluster Storage

2017-12-11 Thread Beau Sapach 
We've been doing some experimenting with gluster, and have built a
stand-alone gluster cluster (not managed by oVirt).  We've been able to
create a storage domain backed by that gluster cluster and run VMs with
their disks on that storage.

The problem we have is that when we take a gluster node down for updates,
maintenance etc. the entire storage domain goes offline in oVirt.  Other
gluster clients, that is servers connecting directly to the gluster cluster
don't seem to notice if one node goes offline.

Is anyone else using gluster storage in oVirt that is not managed within
oVirt?
