Hi all I accidentally deleted a LVM volume directly (rm /dev/System/newcpanel) and now my LVM's are all messed up. I have a snapshot from one of the other LVM's, as follows lvcreate -s -n newcpanel /dev/System/wiseguy -L10G But, instead of running lvremove /dev/System/newcpanel I ran rm /dev/System/newcpanel ( I don't know why) So, now I have waisted space on my server, and I can't remove the original LVM either. root at saturn /]# lvremove /dev/System/wiseguy_rootimg /dev/System/wiseguy_rootimg: read failed after 0 of 4096 at 0: Input/output error /dev/mapper/wiseguy_rootimg1: read failed after 0 of 2048 at 0: Input/output error /dev/mapper/wiseguy_rootimg2: read failed after 0 of 2048 at 0: Input/output error /dev/mapper/wiseguy_rootimg3: read failed after 0 of 2048 at 0: Input/output error Can't remove logical volume "wiseguy_rootimg" under snapshot root at saturn /]# lvscan /dev/System/wiseguy_rootimg: read failed after 0 of 4096 at 0: Input/output error /dev/mapper/wiseguy_rootimg1: read failed after 0 of 2048 at 0: Input/output error /dev/mapper/wiseguy_rootimg2: read failed after 0 of 2048 at 0: Input/output error /dev/mapper/wiseguy_rootimg3: read failed after 0 of 2048 at 0: Input/output error ACTIVE '/dev/System/root' [10.00 GB] inherit ACTIVE '/dev/System/swap' [4.00 GB] inherit ACTIVE '/dev/System/pluto' [50.00 GB] inherit ACTIVE '/dev/System/home' [10.00 GB] inherit ACTIVE '/dev/System/data' [20.00 GB] inherit ACTIVE '/dev/System/andrew_vmswap' [1.00 GB] inherit ACTIVE '/dev/System/andrew_rootimg' [5.00 GB] inherit ACTIVE '/dev/System/keith_vmswap' [1.00 GB] inherit ACTIVE '/dev/System/keith_rootimg' [5.00 GB] inherit ACTIVE '/dev/System/12_vmswap' [1.00 GB] inherit ACTIVE '/dev/System/12_rootimg' [5.00 GB] inherit ACTIVE Original '/dev/System/wiseguy_rootimg' [10.00 GB] inherit ACTIVE Snapshot '/dev/System/oldcpanel' [10.00 GB] inherit -- Kind Regards Rudi Ahlers -------------- next part -------------- An HTML attachment was scrubbed...

Otherwise you could try deactivation and reactiving the System volume group ("vgchange -a n System", "vgchange -a y System"). -- rgds Stephen
