RE: [linux-lvm] More strangeness

["Jason A. Lixfeld" <jlixfeld@andromedas.com>]

No official patch for ext3 and 2.4.10?!  Can I run an older kernel
version?  2.4.8 or 9 maybe?  Will that run ext3 and lvmtools 1.0.1rc4?

This is going back to a comment I made earlier about asking for a stable
version of LVM/kernel to use.  Everyone said 1.0.1rc4/2.4.10 would be
fine (but I didn't mention ext3, because I didn't think it was a
factor).

Advice?
