RAID, Vinum and different disksizes
I have three 120GB disks and one 170GB disk. The first three is forming a raid-5 volume using Vinum and the last one is just fooling around without any purpose. Can I add this 170GB to the raid5 volume in any way at all?

I do realise that I will loose 50Gb, but that's better than not using it at all. from http://www.daemonnews.org/22/vinum.html Like striped plexes, RAID-5 plexes must have equal-sized subdisks and cannot currently be extended from http://www.vinumvm.org/vinum/Future-directions.html Extending striped and RAID-5 plexes is a slow complicated operation, but it is feasible. I am prepared, and desperately hope to be corrected on this but as far as I am aware it is only possible by backing up, recreating a new vinum configuration and restoring. As for losing 50gb I'll swap you a 120gb for the 170gb ;-) ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I do realise that I will loose 50Gb, but that's better than not using it at all. Sorry, no. On the other hand, if the first three were a concat plex, you *could* do it, and you wouldn't even lose 50gb! Your best bet is either: a) mount the 170gb on /usr2 or something b) backup the data on the raid5, restore to a concat HTH, -- Josh ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

There's nothing (much) stopping you from adding another 120 MB subdisk to your RAID-5 plex. I think you'll have to do an attach -f. You *will* lose the contents of the plex (in fact, you'll have to initialize all four subdisks). You'll have to back up and restore your data. I do realise that I will loose 50Gb, but that's better than not using it at all. You can make another volume out of that. Greg -- When replying to this message, please copy the original recipients.
