Hi,
I'm trying to recover some files off a corrupt fs. Everything I've read suggests that 3.2 has a lot of new code that can handle a lot of corruption issues so I thought I'd give it a whirl.. Tried rc4 and today rc5 and the issue I see remains the same.
The primary FS is on an LVM2 LV so I snapshot this before I start working on it. When I attempt to mount the snapshot I get a number of errors reported and then the system seems to get stuck in a loop:-
