If you can do RAID 6, do it so you don't have the heavy rebuild penalty- if you have a spinning disk you might has well put it to use. Agree, main reason to have a hot spare would be if you had multiple RAID5s and wanted to share a hot spare across them, which might save you a few disks. > > ZFS has been mentioned but keep in mind that that really only shines if you have ECC memory Everybody says this, but I've yet to see any rational argument behind it. Yes, if your RAM is corrupted, your disk will be corrupted. This is true of every filesystem out there. I don't see how it is any more or less true for ZFS in particular. Your data isn't safer on some other filesystem; the same failure modes that would corrupt ZFS will corrupt anything I would think. -- Rich ___________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.phillylinux.org/mailman/listinfo/plug-announce General Discussion -- http://lists.phillylinux.org/mailman/listinfo/plug
