And that's exactly why Robin recommended to build LVM on top of a MD device, which will be able to recover from failures.

True, but worth the reserved disk space. epoch1970;649020 Wrote: > After using it, I came to the conclusion that LVM would be great if I > were a sysadmin having to provision homedirs and data volumes all the > time for projects and people at the University, over a large pool of > HDDs. But I was not. You're missing the most interesting point, IMO, which may not be critical to Greg since he wants to use his system as a backup server, and will probably accept downtime: live maintenance. Yes, LVM can be dangerous when misused, but I can also assure you it's saved my day more than once, already. -- sebp 'Last.fm' (http://www.last.fm/user/sebp) ------------------------------------------------------------------------ sebp's Profile: http://forums.slimdevices.com/member.php?userid=11768 View this thread: http://forums.slimdevices.com/showthread.php?t=89504 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
