If you didn't run in striped mode you'd probably be able to recover most of the data from the remaining disks, the exact results would depend on the filesystem used and which part of it was lost. However, in striped mode you'll lose fragments all over the place. Recovering from that is more or less impossible. If your data is precious, use RAID1 or RAID5 and make regular backups. -- Måns Rullgård mru@kth.se _______________________________________________ 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/
