If not , it is useles to strip them. ----- Original Message ----- From: "Fabio Corazza" <[EMAIL PROTECTED]> To: "Humpherys Philip D Contr 532 CMMXS/CL" <[EMAIL PROTECTED]> Cc: <[email protected]> Sent: Wednesday, October 04, 2006 4:32 PM Subject: Re: [Ocfs2-users] lvm2 not cluster aware - okay, so how should Istripe my LUNs? > Humpherys Philip D Contr 532 CMMXS/CL wrote: > > Hi, I'm testing ocfs2 in a 2-node ocfs2 cluster.
