Recovering XFS

tea of evil · 11-22-2008, 10:35 PM

I was hoping for a filesystems forum, but here goes.

I had a nice big XFS partition spanning two disks using LVM. Key word here is had; one of the disks went. dd_rescue and 25.9 hours later I had my LVM restored.

Problem is my XFS partition is now corrupted (or so xfs_check tells me). I ran xfs_repair, but it only brought back about 5% of the files I had on there, everything else is gone.

Is there a better way to recover XFS aside from xfs_repair? Did I just destroy nearly everything by using it?

Unless you where using LVM on a Hardware Raid or Software Raid then I am going to say I am pretty sure that yes you have lost some or at worst most of your data. LVM is a way to take multiple hard drives and make it appear as on very large volume, not a Raid replacement but more of a supplement.

Yeah, I figured it was mostly gone. I probably should have done xfs_dump to an image then xfs_restore to try to pull off data, instead of trying to repair the FS directly.

Oh well, at least my database is still intact.
