Ahh I made a major typo .... it's a linear setup, not a striped one. You mentioned anyway that a recovery would be somewhat possible. I'm using ext3 journaling fs on my LV. Would I be able to mount this LV if one PV died, meaning I would see all data except the part that was lost with that drive or would I need to do anything special to make the LV mountable again ? --------- Perplexer ----- Original Message ----- From: "Måns Rullgård" <mru@kth.se> To: <linux-lvm@sistina.com> Sent: Tuesday, March 02, 2004 1:08 PM Subject: Re: What if a drive dies ? > "Perplexer" <perplexer@thz.net> writes: > > > Hello. > > > > I'm sorry if I ask something that's be asked a million times before but I > > prefer answers to my specific questions.
