Take an initial snapshot (live) with rdist, then when you're ready to do the final copy, the offline rdist will run much more quickly, resulting in less downtime. Replace rdist with rsync if you like. --Doug ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Migrating a file system with minimal downtime
I want to migrate a file system containing multiple jails from a small drive to a large (RAID-1) array. I want to do this with minimal downtime. Simply shutting down the jails and using dump/restore to move the file system takes too long, but what if I do it in several steps like this: 1. "dump -0 -L -f - /usr/jails | restore -rf -" to dump the live file system at level 0 2. shut down the jails 3. unmount the original file system 4. "dump -1 -f - /usr/jails | restore -rf -" to dump any changes since the first dump 5. remount the new file system in the proper location 6. restart the jails This should work, right? Or am I missing something? (One of the jails is a mysql server, the rest are www servers.) /Daniel Eriksson ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
