Cheers, Matthew Well, to 'fail' the drive, you'ld have to physically pull the drive from the chassis which will involve a power cycle unless you've got hot-swap drives. Of course, you should confirm that your system will boot with the RAID in a degraded state and that rebuilding the RAID will continue even if interrupted by a reboot. gmirror(8) passes those tests. You do have to type some commands to get a mirror to rebuild (examples are shown in the man page) unlike some hardware RAIDs where simply inserting an unused disk is sufficient. --=20 Dr Matthew J Seaman MA, D.Phil. 7 Priory Courtyard Flat 3 PGP: http://www.infracaninophile.co.uk/pgpkey Ramsgate Kent, CT11 9PW --------------enig40BF98BF2875620A45ACCFAE Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEAREIAAYFAkmQt2MACgkQ8Mjk52CukIzRHQCfVEw13W+fu83Q41Wk402/H7Yy PswAnRJgvMRkiNvG9I9zCgKoDtvlVQrn =GoM7 -----END PGP SIGNATURE----- --------------enig40BF98BF2875620A45ACCFAE--
