If you see physical disk errors or LVM errors, it's likely that the filesystem may have been corrupted. Sometimes the filesystem corruption may not be noticeable until much later, and the longer you wait, the worse your data may get scrambled. So if you were seeing all sorts of disk or LVM errors, don't just assume that the problems all went away when you moved to a "stable" kernel. So after seeing this kind of disk problems, *always* run fsck -f to make sure the filesystem is in a sane state before you continue. Any journaling filesystem, like ext3, will protect you against needing to run fsck after an unclean shutdown, but they all won't save you if you have low-level disk/LVM errors. In those cases, you still need to have a filesystem checker to try to pick up the pieces caused by hardware problems, kernel bugs, etc. > One of the lost+founds is stuck on my LVM and I can't delete it. > Every time I try, it gives me permission denied errors.

Recent versions should have offered to get rid of corrupted files for you. > Why is all this happening? What do I need to do to get this all > working? This isn't complicated, is it? 10 drives, 3 LVMs and one > ATARAID?! Umm.... you're using bleeding edge 2.4 kernels, LVM's, and ext3? Err, yeah, this is still complicated. Given all of the changes going into the kernel, even though a lot of work had gone into making earlier versions of LVM and ext3 play nicely together, your milage may definitely vary (and I haven't even included the ATARAID aspects).. I wouldn't put any production data on it just yet, until things have done a little settling down. - Ted
