--YD3LsXFS42OYHhNZ Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi, I was wondering about the vinum 'rebuildparity' command, especially the times when one needs to use this. I just recently found out, based on reading the RAIDframe documentation, that you're supposed to recheck/rebuild the parity after every disk crash. As I hadn't been doing that that would explain a lot of corrupted data in the past few weeks :/ The problem is that I can't find anything in the vinum docs about this command other than it's purpose. What I don't understand is the difference between reviving a disk in a RAID-5 plex, and rebuilding the parity. When I start a degraded disk it starts to revive -- which led me to believe that vinum was also recalculating the parity. Evidently it wasn't. I'm therefore now updating my procedures to always run 'checkparity -v <ple= x>' after a disk crash. Does anyone know if this is supposed to be this way? --Stijn --=20 "A mouse is a device used to point at the xterm you want to type in." -- Kim Alm, alt.sysadmin.recovery --YD3LsXFS42OYHhNZ Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFBLE5bY3r/tLQmfWcRAlqYAJ0ftKQAZX8SsIcbAOBstCOzzukxOACdFCNg sATUwZt7ReS63XSEUULiF6w= =Sffj -----END PGP SIGNATURE----- --YD3LsXFS42OYHhNZ--
