Yes and No. There was a max pv size. If you use metadata format for version 1 it has a hard limit of 2 TiB for a pv size. Using metadata format version 2 it is an unsigned long int so the max pv size is 4 exabytes in length. If you feel that the pv size is holding you back you can force metadata version 2 when you execute pvcreate (e.g. pvcreate -M1 for metadata version 1 or pvcreate -M2 for metadata version 2). > thanks for any help. I hope that helps. I can't imagine it actually being in reiser so I'd try recreating the pvs. Zac Slade krakrjak@volumehost.com ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/ _______________________________________________ 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/
