Hi,
I'm investigating a report where after few crashes ZFS got corrupted in
a way that the corruption is not reported by scrub.
The problem is that one of the directories disappeared, but its name is
still listed in parent directory.
For example when I do 'ls' in the parent directory I get:
# ls
ls: missing: No such file or directory
<other entries>
'missing' is the name of the missing directory. Which means that the
'missing' directory is still listed in its parent.
Its inode number as reported by getdents(2) is 48. Now when I use zdb to
find object with this inode number I get:
# zdb -dvvvvv tank/data 48
Dataset tank/data [ZPL], [...]
Object lvl iblk dblk dsize lsize %full type
zdb: dmu_bonus_hold(48) failed, errno 2
On the other hand, when I do the same for its parent directory object I
get:
# zdb -dvvvvv tank/data 4
Dataset tank/data [ZPL], [...]
[...]
missing = 48 (type: Directory)
[...]
When this directory disappeared it had lots of entries.
Any ideas what might have caused this and eventually do you see a way to
recover that directory?
