[linux-lvm] Problem creating snapshot with 2.6.15, lvm2

[Nate Carlson]

Hey all,

I'm running lvm2 on a Debian box; LVM utilities version 2.01.04-5 and 
kernel version 2.6.15. I'm trying to create a snapshot, and get the 
following error:

fs:~# lvcreate -L1G -s -n Documents-backup /dev/HomeVG/Documents
   LV HomeVG/Documents-backup in use: not removing
   Couldn't deactivate new snapshot.
fs:~# lvscan
   ACTIVE            '/dev/HomeVG/Documents' [10.00 GB] inherit
   ACTIVE            '/dev/HomeVG/Documents-backup' [1.00 GB] inherit

Any idea what I can do to debug the above error? Documents-backup does not 
have a valid filesystem structure on it, but I can kill it with a 
lvremove.

Thanks!

I've this error too, and I update to lvm2-2.02.01-1.2.1 /Fedora version,
it's meaning 2.02.01/ and usually it's working now for me. I don't dare
to use it with a productive environment.

[sorry; been going like crazy lately, and hadn't had time to get back to 
this.]

I tried upgrading to a 2.6.16 kernel, and LVM tools version (debian 
package) 2.02.02-1.. still get the exact same error:

fs:~# lvcreate -L1G -s -n Documents-backup /dev/HomeVG/Documents
   LV HomeVG/Documents-backup in use: not deactivating
   Couldn't deactivate new snapshot.
fs:~# lvscan | grep Documents
   ACTIVE            '/dev/HomeVG/Documents' [10.00 GB] inherit
   ACTIVE            '/dev/HomeVG/Documents-backup' [1.00 GB] inherit

Any other ideas?

Thanks!
