I do wonder how you managed to allocate parts of the various copies of the RAID drive onto the new physical drive.

It's impressive what you can do during a RAID recovery. That said, I probably wouldn't try doing a major system upgrade that involves a new kernel and new RAID software during such a recovery! And presumably you did have to shut down the system while you were physically replacing the drive? -- hendrik > > nick > > _______________________________________________ > mlug mailing list > [email protected] > https://listes.koumbit.net/cgi-bin/mailman/listinfo/mlug-listserv.mlug.ca _______________________________________________ mlug mailing list [email protected] https://listes.koumbit.net/cgi-bin/mailman/listinfo/mlug-listserv.mlug.ca
