| |
I get the following error on fsck:
Pass 1: Checking inodes, blocks, and sizes Extended attribute in inode 3093 has a hash (2257320705) which is invalid Clear<y>? yes Inode 3093, i_blocks is 16, should be 8. Fix<y>? yes
To reproduce:
[mount ext4 image] mkdir xattrhashtest cd xattrhashtest/ mkdir upper lower work mnt cd lower/ echo foo > bar ln bar baz mount -t overlay overlay -olowerdir=lower,upperdir=upper,workdir=work mnt cd mnt/ echo xxx >> bar [umount and fsck]
Reverting commit daf8328172df ("ext4: eliminate xattr entry e_hash recalculation for removes") fixes it.
Might be an ext4 or overlayfs bug. Let me know what you think.
Thanks, Miklos
