Hi, I have the following problem: when running vgchange -a y vg I get errors of the following type: Volume group uuid not found: ... The ... stands for the concatenation of the VG uuid and the LV uuid for that volume (this is repeated for each logical volume.) The result is that the group is not activated. This happens also with a new test VG and LV I created, and for any operation with the LV (though sometimes the operation succeeds despite the message, eg when creating a new LV.) Here are some other diagnostics that may be relevant: When I run pvs I get the message Can't read vg: skipping When I run lvdisplay -v /dev/vg/home I get (among other things) LV status: NOT available I tried running 'vgcfgbackup' and 'vgcfgrestore', it didn't help. The whole thing used to work, so this may be a result of some upgrade. This is all happening on a Gentoo system, with kernel version 2.6.16. The output of lvm version is: LVM version: 2.02.03 Library version: 1.02.03 Driver version: 4.5.0 I can't try too many things there since almost all partitions on the machine are managed by lvm. Any help is greatly appreciated, Thanks, Moshe -- I love deadlines. I like the whooshing sound they make as they fly by. -- Douglas Adams Moshe Kaminsky <kaminsky@math.huji.ac.il> Home: 08-9456841 _______________________________________________ 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/
