Re: [Users] [node-devel] GlusterFS on oVirt node
I reinstalled node and remounter / rw then I checked fs before activating host (in oVirt Engine) and after (which files have been changed)... The ro problem seems to be in /var/lib/glusterd/. Is there any way I can change node so this directory would be mounted rw? And to persist this setting after reboot. tnx Dne 24. 10. 2013 15:28, piše Fabian Deutsch: Am Donnerstag, den 24.10.2013, 15:12 +0200 schrieb Saša Friedrich: Progress report: I remounted fs on oVirt nodes rw, started glusterd with no errors.

Re: [Users] [node-devel] GlusterFS on oVirt node
Thanks, I'll try that (and report). And I think data in that path don't need to be persistant, because when I reboot node, and make whole fs rw again, host gets attached to oVirt with no errors. One more thing. Messages log file keep getting me errors (every 2 sec): Oct 25 08:32:50 localhost python[462]: service-status: ServiceNotExistError: Tried all alternatives but failed: Oct 25 08:32:50 localhost python[462]: ServiceNotExistError: gluster-swift-object is not a SysV service Oct 25 08:32:50 localhost python[462]: ServiceNotExistError: gluster-swift-object is not native systemctl service . . . . . Oct 25 08:33:18 localhost python[462]: service-is-managed: ServiceNotExistError: Tried all alternatives but failed: Oct 25 08:33:18 localhost python[462]: ServiceNotExistError: smb is not native systemctl service Oct 25 08:33:18 localhost python[462]: ServiceNotExistError: samba is not native systemctl service Oct 25 08:33:18 localhost python[462]: ServiceNotExistError: smb is not a SysV service Oct 25 08:33:18 localhost python[462]: ServiceNotExistError: samba is not a SysV service So I somehow lost hope for node and tried makeing host from fc19 (minimal installation). Installed, attached host in oVirt engine, but... Errors are the same!

The patch just adds that path to /etc/rwtab.d/ovirt - this will tell the read-only root to make that path writable at boot.

Greetings fabian Acording to log /var/lib/glusterd/glusterd.info is missing and can not be created because fs is mounted ro. Now I'm stuck!

Re: [Users] [node-devel] GlusterFS on oVirt node
Am Donnerstag, den 24.10.2013, 15:12 +0200 schrieb Saša Friedrich: Progress report: I remounted fs on oVirt nodes rw, started glusterd with no errors. Then I activated hosts in oVirt Engine. Also no errors! Yei! Yey! :) Yes, mount -oremount,rw make's the FS temporarily writeable. But you will have issues as soon as you reboot. We'll need to investigate which paths need to be persisted (so the data written to them survives a reboot) and which only need to be write-able e.g. for temporary data. Would you mind opening a bug for this? Greetings fabian Then I created volume (replication), added two bricks (oVirt nodes), and started volume. Seems fine.

Now I created two hosts (nested kvm - ovirt node fc19 - just for testing) and added them in oVirt. Super fine - working! Now I'd like to use this hosts as glustefs nodes too.
