>Description:
recently i had a hard drive failure. the problem was, the bad block was apparently not where data or ordinary metadata was stored, but 'under' an acl. the occasional method of finding damaged file to restore from backup ("(find / -print0 | xargs -0 cat ) > /dev/null") failed - the kernel said 'Error retrieving ACL on object' without returning EIO to the userland.
>How-To-Repeat:
>Fix:
that place in /sys/ufs/ufs/ufs_vnops.c is marked with 'XXX: fall back until debugged'; probably there should be 'return (error)' before the closing brace.
