Yes, if you use mdadm at the command-line to create the array. Assume the existence of four drives, plan your RAID layout accordingly, then when comes time to run the mdadm --create command, substitute the keyword "missing" for "/dev/sdX". If you're using LVM or device-mapper, then this method won't work. You can even build a RAID-5 array on two drives this way (but it's as slow as running in degraded mode - because it *is* in degraded mode). In your place, if the SATA ports in the system are bootable, I would sacrifice 100Mb from each of the 750Gb drives as a "/boot" partition - RAID-1 x 4, then set up the rest of the drives as the root FS. You'll see a *dramatic* speed gain over the single 120Gb IDE drive that way. -Adam -----Original Message----- From: Kevin McGregor <kevin.a.mcgregor@gmail.com> Date: Mon, 8 Feb 2010 17:50:39 To: MUUG Roundtable<roundtable@muug.mb.ca> Subject: [RndTbl] RAID on Ubuntu _______________________________________________ Roundtable mailing list Roundtable@muug.mb.ca http://www.muug.mb.ca/mailman/listinfo/roundtable
