[linux-lvm] RedHat 9 lvcreate snapshot failure.

[linux-lvm] RedHat 9 lvcreate snapshot failure.

[Richard Collins]

Running Redhat 9 and trying to create a snapshot for a safer backup of a
logical volume, I get the following error.  Surfing the net didn't turn up
anything.  Any help would be greatly appreciated.

Thanks,

Richard

This seems to be a bug in the RedHat Kernel:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=97843

Should be fixed in the latest errata kernel, but I have not verified that.
