Do you know how to do RAID5 ? I read in http://www.essenz.com/support/lists/hackers/20040118/69.html about geom_raid, but it seems to be lost after that. The other alternative may be to setup a RAID1+0, but that shrinks my usable space, and I'm not sure how reliable/advisable it is to do in software. Thanks again, Beto It's not possible to use RAID 5 for bootable slice, so I would suggest: - Create a mirrored slice for the root FS - Create a RAID 5 slice for the other FS I did the same here with vinum. Also as you have 3 disks you can make a 3 disks mirror for the boot slice. The other option is to make mirror on 2 disks and on third to put swap :) Best regards, Ivailo Tanusheff Senior System administrator ProCredit Bank (Bulgaria) AD tel. +359 2 921 7161 fax +359 2 921 7110 http://www.procreditbank.bg Disclaimer: The information contained in this message is intended solely for the use of individual or entity to whom it is addressed and other authorized to receive it.
