I have (had) a 3 disk RAID array, which was managed with EVMS and used LVM2 for partitioning. After a power cut, it was damaged (not physically though, but EVMS wouldn't bring it up). I tried removing and re-adding the dirty disk, but it wouldn't work. I tried reassembling the array with mdadm, but I got errors about no superblock on sda1. I tried re-creating the arrey with mdadm, and it worked, synced up, but when it came back online, EVMS could not mount the partitions from the LVM volume. They appear to have no filesystem on them. Which means I missing a lot of data
Should I try to create a filesystem, or will that overwrite any data I might be able to recover with a recovery firm or something.
Any suggestions would be *very* welcome!
