Yes, provided the existing filesystem is not using the last block of its provider (partition), but you'll have to put the journal on a separate provider from the data. See the explanation of the -s switch in gjournal(8) to determine the necessary size of the journal provider, but don't specify -s in the "gjournal label" command because the size of the journal is implicitly set by the the size of its provider when separate from the data provider. (-s is used when a single provider is used for both journal and data.) Also read the explanation of the -f switch, but don't actually specify -f unless you are sure you know what you're doing :) Something like this [untested]: # umount [existing filesystem] # gjournal label [existing filesystem] [journal provider] # tunefs -J enable -n disable [existing filesystem].journal # mount -o async [existing filesystem].journal [mountpoint] and edit /etc/fstab accordingly. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
