[LUAU] LVM Restore

[Michael Bishop]

Hi all,

I'm looking for a LVM expert or advice on how to restore an LVM from a recovered RAID array. This data needs to be recovered ASAP and I'm willing to hire someone to get it working ASAP.

The RAID array on a 3ware card was changed from a RAID 5 to a RAID 10, then back to a RAID 5. The system was recovered using RAID Reconstructor and placed on a new RAID Array. 

This is a Centos4 OS with 3 partitions: first partition had the OS; 2nd partition was swap; and the 3rd most important partition contained a large 500G LVM. Though I'm not sure because the partition table also had to be rebuilt.

gpart ran for about 2 hours, but I killed it because I didn't think it should have taken that long. I found an app called Partition Table Doctor which ran for 30 mins and found 2 partitions that looked about right. Though it didn't find the swap partition there was a space between the partitions, but double the size of what I expected the swap to be. Which is why I'm concerned that the 3rd partition wasn't restored properly.

I'm able to boot the system using grub from another hard drive. So the first partition made it, but a pvscan comes up blank. It doesn't even list the LVM as invalid or missing. All I need is the data in the LVMs. Another server has already been built to put the data on it.

Please email me or give me a call if you can help, 429-3030. Again, I'm willing to pay an expert to fix it.

This has been quite a journey, so I'm planning on documenting it on the HOSEF wiki to hopefully it can help someone in the future.

Thank you.

Michael
