On the xfs regression test I posted yesterday, there is concern that my check for lvm being present in the kernel is not general enough to check LVM 1 and LVM 2, or even EVMS. Can anyone recommend a more general method of checking? Possibilities: lsmod | grep lvm only looks for modules, so it is flawed. if [ -d /proc/lvm ] apparently only works for LVM 1 grep lvm /proc/devices might be a good choice, but I assume will not find EVMS setups Greg Freemyer Internet Engineer Deployment and Integration Specialist Compaq ASE - Tru64 v4, v5 Compaq Master ASE - SAN Architect The Norcross Group www.NorcrossGroup.com ---------- Forwarded Message ---------- FROM: Andi Kleen <ak@suse.de> TO: Ragnar Kj?rstad <xfs@ragnark.vestdata.no> DATE: Thu, 29 Aug 2002 14:37:37 +0200 RE: Re: Draft Snapshot Regression Test On Thu, Aug 29, 2002 at 02:11:46PM +0200, Ragnar Kj?rstad wrote: > > On Thu, Aug 29, 2002 at 05:58:21PM +1000, Nathan Scott wrote: > > > #Verify we have the a lvm enabled kernel > > > # TODO (This assumes lvm is a module.
