Unable to mount snapshot LV when fs=ext3 on Linux kernel 2.4.20

Hi,

Linux Red Hat 9.0 kernel 2.4.20-8
I have created a ext3 fs on a LVM logical volume : OK. create a snapshot on it, trying to mount it :

[root@linux05 proc]# mount /dev/volume01/snap01 /SNAP
mount: block device /dev/volume01/snap01 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/volume01/snap01,
or too many mounted file systems

No problem with an ext2 file system.

Any explanation ? a bug ? a bad patch for VFS locking in the kernel ?

Sounds like the VFS lock patch is not in the RH kernel, or is not patched in correctly.
