Trying to recover a crashed disk....
I was under the impression that using LVM tools like 'pvscan' and 'lvscan' could find the LVM partitions, if you could get past the first few sectors/cylinders of the disk. That is the volume groups info was 'out there' regardless of the tables manipulated by fdisk.
I'm having trouble doing the latter, outer cylinder may be corrupted.
Ideas?
Remember people that LVM is for controlling the size of partitions NOT for providing RAID like protection. If a disk crashes you can/will lose all of your data. If you want both you need to start with RAID first then create your LVM partitions on the RAID device.
And to the extent your LVM is made up of multiple physical (non raid) disks, your risk is increased with LVM. Any failure will likely kill your whole file system. Three small disks have three times the failure potential of one big one. --i I suspect that Linux does better at this sort of thing than windows, which may have a single file scattered all over the disk, whereas Linux tends (tries) to have it all in one place in consecutive locations. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
