Hi,

I read a few emails on this mailing list with the same
problem. I'm using LVM version 1.0.1-rc4, kernel
2.4.7, Redhat 7.2. I've been unable to activate a VG
since yesterday. I've been trying to recover data from
the VG using  the "pvcreate, vgcfgrestore, vgscan,
vgchange" procedure given as a solution to this
problem. I still get the following error:
vgchange -- ERROR "parameter error" setting up
snapshot copy on write exception table for
"/dev/vgtest/snap.02"

I've tried using all the old config files for this VG
in /etc/lvmconf, but even the oldest file has the
"messy" snapshot since the snapshot creation was being
done as part of an hourly cron job. 

I would appreciate it if you could let me know whether
there is any other way to still recover the data on
the disk ? Also, is there a later version of LVM in
which this problem has been fixed ?

Thanks,
Gayatri
