I seem to have overlooked the first part of your reply, I can just replace the disks one at a time, and of course the pool would rebuild itself onto the new disk. Would this automatically extend the size of the pool once all 3 disks are replaced? thanks - -- Matt Harrison [EMAIL PROTECTED] http://mattharrison.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) iEYEARECAAYFAkhmEUcACgkQxNZfa+YAUWFYewCfdA2Ax4fU2NUNK+mOtdI+pT2W cMsAnj0FSaQp7DNdTpU61IqCCjytY8T3 =k8aG -----END PGP SIGNATURE----- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
