I have been trying to use LVM on what started out as a standard red-hat
9 system. The supplied kernel had problems with out network card and
DHCP, so I am now attempting to use a stock 2.4.20 kernel patched with
lvm-1.0.7. Everything works fine except that I cannot make a snapshot of
a mounted ext3 filesystem. When I attempt to mount the snapshot
(readonly) I get:-
mount: wrong fs type, bad option, bad superblock on
/dev/vga/addon.backup,
or too many mounted file systems
I get the same problem with reiserfs, but not with ext2. Searching the
list archive suggests that I need the VFS-lock patch. I presume this is
already included in the patch-set I build as part of the LVM
installation (applying this patch separately after the generated LVM
patch breaks the kernel, leaving me with unresolved reverences to
fsync_dev_lockfs and unlockfs).
What should I try next?
