Expanding a Vinum RAID-5 array
Is it possible to just 'plug-in' another disk to a vinum RAID-5 array and let vinum start building a new index based on the new volume-size? All this without any data-loss? ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

No, sorry. You can (forcibly) add another plex (I think), but it will involve complete data loss (another way to say backup/restore data). What you can do, if you have enough disk, is to create a second RAID-5 plex of the desired size and start it from the first. After that you can release the disks of the first plex.

Re: Expanding a Vinum RAID-5 array
Hmm, this completely ruined just about all of my storage plans. :-) Do anyone know other (read hardware) RAID-systems that are known to work well with freeBSD and also allows me to increase the total diskspace without dataloss?

I don't. The problem isn't the RAID system, but the UFS file system which doesn't allow expansion. Vinum's ``concat'' mode allows one to add capacity, but not to expand the size of existing file systems. Are there any file systems that work with FreeBSD that allow expansion after the fact?

Is there something about grows(8) that I'm missing? It's entirely possible that I've missed the context or something, but I'm grown UFS filesystems (on vinum concat's, actually) several times wih great success. -T -- Behold, O Man, you can create life.
