Hi,
Well, in general it should work.. we'd need to see the error to know if
there's a special-case you've fallen into.
A follow-up to describe what I have found regarding Fedora 8 and my
attempts to use LVM snapshots to hold Xen guest images. Maybe it will
help others.
In general, I was unable to create any LVM snapshot with an out of the
box configuration of a 64 bit Fedora 8 until I manually loaded the
"dm-snapshot" kernel module.
modprobe dm-snapshot
Then, I was able to create a snapshot volume and all seemed fine until I
rebooted the machine. The boot sequence failed with a message about
"unable to expand snapshot volume" which I assume was caused again by
the lack of the "dm-snapshot" module. I used the rescue disk to remove
the snapshot volume and was able to boot my machine once again.
I found a number of postings on the debian mailing lists from 2005
regarding the same issue and peoples attempts to get the "dm-snapshot"
module to load during boot.
I played around with modules.conf.d configuration to try to get the
module to load on boot but didn't have any success.
Do I need to make a custom boot/initrd script or am I on the wrong
track? Ideas are welcome.
In the mean time, I have resigned myself to just not ever rebooting the
machine while any snapshot volumes exist.
