Hi Christian, yes you can online and use the 3rd host as long as you don't use "cluster.choose-local on" as the local data is not ready yet and the FUSE client will first query the local brick and later query another one (extra lattency - less performance). By default ovirt is disabling the choose-local, so you should be OK. Actually, even if the gluster brick died on that host (for example the RAID is broken), the ovirt node can still use other Gluster bricks - just like oVirt compute-only nodes.

I recently swapped all the storage SSDs with bigger enterprise grades SSDs. So I took a host down (migrating all VMs away, maintenance, shutdown, fix raid, gluster repair, back online). This worked well and all three nodes are now hardware-wise replaced. The last one is still gluster-healing (roughly 20% done).  The other two nodes are happily serving the vms while the third one is still in maintenance. my question is: Can I online the maintenance node while gluster is still healing? Or will will open up a can of worms I would not like? It would be cool having all three nodes back online soon while the gluster is still repairing. We have no urge tho. If there is a risk I would wait. If this is somewhat risk-free and do-able why not :) -- with kind regards, mit freundlichen Gruessen, Christian Reiss _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/IN2KT7UHJ5G...
