I had grabbed a dumpe2fs dump of the corrupted file system and one of the newly-created file system on the same device. Adjusting for normal variation (numbers of free blocks, flags, etc.), there are no differences _except_ in the very block groups that fsck complained about having bad checksums. For those (and only those), the locations of the block bitmap and inode table differ. I've attached the diff output. In particular, block group 276 claims to have its inode table at blocks 0-204, which is clearly wrong. This is the block group for which the allocation failed, causing the original loop. It's clear that fsck is neither correcting the block groups nor is it detecting the bad entries properly (a sanity check might be in order here). It's not even noticing that it's looping, it just keeps failing the allocation and retrying. While it may be that fsck can't recover the file system in this case, it should at least notice and abort. My thinking is that the location of the inode tables should be invariant over the life of the file system. Certainly there's no place in ext4 itself that changes those fields (that I can see, anyway). Why couldn't fsck compute the proper values and compare those against what's there? -- Frank Mayhar <fmayhar@xxxxxxxxxx> Google, Inc.
