Thanks a lot Ray, I will give a try as soon as I can find a window as the server is in production. Anyway, I add some information. As I said, the lvm system stop responding after a lvremove of a snapshot. This snapshot is a snapshot of a clustered system (clvm) but with exclusive use. When I remove it (and it works) the snapshot is active. I thought that maybe that was the problem, so I tried to deactivate it first with the result: [root@s02 ~]# lvchange -an /dev/vols-001/vol01-autosnap-1333451491 Can't change snapshot logical volume "vol01-autosnap-1333451491" Don't know if I am doing it the correct way, but I am unable to deactivate the snapshot. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
