Re: [linux-lvm] Corrupted LV after resize2fs crashed when adding new disk to LV

[Ken Bass <daytooner gmail com>]

The gods of Linux must be watching over me . I shall never blaspheme against Linux again!

I had removed the new drive from the VG, then restored the VG (vgrestore) to an archived version created before I had added the drive to the PV. I then added the drive back to the VG (vgextend), extended the LV partition to the max (lvextend), then resized the LV (resize2fs). Oh, before I could do the resize, I had to run e2fsck, which praise the gods, ran successfully. As did the resize. 

I re-ran e2fsck (with -f) and ir ran 100% successful and clean.

And then the piece de resistance - I mounted the LV and everything was as I orginally wanted. The old data was still there and valid, and the new size of the LV was the original + the new disk!!!!!

I don't know what I did to make this work. I all seems magical to me now. As with Stuart's below:

Thanks all.

This is from Mozart's unfinished Requiem. If you watch the movie Amadeus, it is at the end right before he dies. I don't know Latin very well, but I think it has something to do with the burning flames of h*ll :-).

Look at your metadata backups, and see if you can find the version with
the larger LV.  Look at the timestamp on the revert to get a clue on
how it got reverted.

First, I would make a copy of what you got (it will fit on a cheap
external USB disk) before making any more mods.  Then restore the metadata
to the extended LV before retrying e2fsck.
