I just changed provider names for a gjournal'ed disk when my disks were reordered, and with the proper corresponding changes to fstab, there were no problems -- everything was mounted and loaded upon reboot without me having to make any other changes. However, if you used the "-h" option with "gjournal label" you may have to manually relabel. >> Otherwise I only use labels (ufs) for quiet some time, so I thought >> testing would be painless... >> Can I safely remove glabel from the unmounted fs and relabel the new >> device? >I don't very understand whet you mean by "safe"? Safe for what? He means, can he relabel the disks without losing any data on them? I think that the answer is yes, provided he doesn't do anything foolish -- like relabel an existing file system with journal and data on the same provider, while increasing the size of the journal, which would cause all data on the space allocated to the new journal to be lost. He may have to use the "-f" flag with "gjournal label", or issue "gjournal clear" before relabeling, and he may lose the last sector of the file system and anything on the journal, but that usually isn't of any consequence. In any event, unless he hardcoded his provider names, this probably isn't necessary. If it does prove to be necessary, it would be wise to back up any data just to be safe, and to experiment on a test provider first, before trying to relabel. b.Received on Sun Jul 05 2009 - 07:15:03 UTC
