Anyone with any great ideas on partition recovery? One of my servers went to a hang yesterday, I rebooted and nothing happened.. Both the first and second volumes on the Compaq Array has lost their partition tables, how that now can happen... The first volume contained the root and swap file systems, the second carried the /home sub tree. I've made disk copies with dd to files, but how would I go on from here? gpart doesn't find anything on any of the volumes, I haven't tried Partition Magic yet, someone suggested that one, but I can't see how it would do any good. Suggestions are really welcome! Anders Norrbring Norrbring Consulting

If all you lost is the partition table, you should be okay. I just googled for "partition table recovery" and found lots of interesting choices. If you know the general layout of your table and your willing to do some manual work, give this a read: http://www.datarescue.com/laboratory/partition.htm http://www.datarescue.com/laboratory/partition2.htm Sort of old, but it should still apply.

I've also found tips that I should simply use fdisk to set up the first partition, verify it and if needed, adjust the end cylinder. When done, set up the next partition, verify and so on... I don't know which way would be the simplest, or safest.. I don't really care about the system volume, that can easily be reinstalled, but the /home volume carries some very important changes since the last backup... Therefore it's really imparative that I can restore that one.. Anders.

So long as it's just the partition table that's fscked gpart (which will already be installed) is pretty damn good at locating partitions and re-creating the partition table. Dylan -- "The man who strikes first admits that his ideas have given out." (Chinese Proverb)

As I mentioned in the first question, gpart doesn't find anything, instead it reports an error "Fatal: /dev/ida/c0d0 seek error" Anders.

And the array is fine?
Yep. Both arrays are free from problems, I've checked them with Compaq Array Diagnostic Utility. Nothing at all reported. Anders.

parted will do it rescue START END rescue a lost partition near START and END I have fully recovered partitions on a disk that had the first sector zeroed out. And I don't know how that happened either. :-)
