How do you achieve that? 2 hours? Install new drive for db is 10min of DC engineer hand work (if drive is HHHL and need power off server). Then after server is boots your mon already up. After you provision new drive, make fstab, is stop, rm old monstore, mount new, mon mkfs, start. Even if this is not covered by script is max 5 minutes to reach quorum.

We have 3 MONs and I needed to migrate each MON store to new storage. Of course I managed to install the new disks in one and wipe the MON store on another MON. 2 hours downtime. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
