Anyway, I used to use 3ware devices but have since come around to loving the Linux software RAID paired with LVM2.
The problem I had was that I wanted to upgrade my RAID controller since I no longer had a board with PCI-X slots. It was a complicated upgrade procedure that may actually hose the data in the array. Anyway, LVM works as long as I have a Linux install (which I always have on me with a bootable USB drive loaded with systemrescuecd). The point is that I prefer the standard Linux software RAID stack. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkpVHHsACgkQwRXgH3rKGfM/0wCgkkX2gVrzINncFhfQzm4MIjwe QYAAniSHT/NOSrFeAG/DtoKXwWcmXibj =Pdvb -----END PGP SIGNATURE----- _______________________________________________ clug-talk mailing list [email protected] http://clug.ca/mailman/listinfo/clug-talk_clug.ca Mailing List Guidelines (http://clug.ca/ml_guidelines.php) **Please remove these lines when replying
