Re: [ovirt-users] remove a lost gluster based datacenter
Looks like the cluster has both virt and gluster services enabled. Otherwise a host part of gluster-cluster cannot be a SPM. I am not sure about the standard procedure to removed a SPM host. Once SPM is disabled, you should be able to remove all the gluster hosts forcefully.

Tibor Tibor, This is not an officially supported solution, but I had a similar issue myself at some point (virtual gluster hosts that I was silly enough to delete without first stopping the volumes). Basically the status of the volumes is stored in the gluster_volumes table, status column. If you manually update the status to be 'DOWN' instead of 'UP' for the volumes that are giving you trouble. Then in the UI they will be down as well. At which point you should be able to properly remove them from the UI using the UI. Once that is done you should be able to simply remove the offending hosts as there are no longer any gluster volumes associated with it. I am sure there is a much better way of doing this (maybe REST api?), but I couldn't find it (I am not a gluster expert). Alexander - Eredeti üzenet - Hi, I have try it before wrote this mail. It is impossible, it is a spm host Error while executing action: Cannot switch Host to Maintenance mode. Host is Storage Pool Manager and is in Non Responsive state. - If power management is configured, engine will try to fence the host automatically. - Otherwise, either bring the node back up, or release the SPM resource. To do so, verify that the node is really down by right clicking on the host and confirm that the node was shutdown manually. When I want to switch to maintence a non-spm host: Error while executing action: gluster4: Cannot remove Host. Server having Gluster volume. When I want to remove an gluster brick: Error while executing action: Cannot stop Gluster Volume. No up server found in glusters. When I want to remove a VM that was on this gluster based datacenter: Error while executing action: F19glusters: Cannot remove VM: Storage Domain cannot be accessed. -Please check that at least one Host is operational and Data Center state is up.

Hi. I noticed one important thing is that the service does not start ovirt-engine-dwhd. I have no idea why this happens. I tried to look for some logs for this service, but nothing. If you have any idea where to look or what to do, I'd be grateful. Grzegorz ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

You could put this into your gluster servers in /etc/glusterfs/glusterd.vol option base-port 50152 so that port conflict with libvirt goes away. You have to stop/restart your gluster servers, so that you have to put infra into maintenance. Gianluca ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

We are in the process of installing Zentyal for the SMB purposes on a guest and it would be great to have that guest also serving a fs path directory with NFS + SMB (which is semi crippled on the host after oVirt installation with version 3 et.c.). Does anyone have an idea of how I can through oVirt (seen several solutions using virsh and kvm) letting my Zentyal Ubuntu guest have access to a host mount point or if necessary (second best) a seperate partition? Best regards Niklas Why not just give the guest a thin provision virtual hard drive and expand it on a demand basis? /K Thanks for the advise but this would not suite us I'm afraid. It would be difficult wrt incremental backups as well as host machine file-routines. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
