[I had first posted onto the Forum about this issue]
Two months ago,
- next to a call to |`||delete-old-libs`| or `install world`, I don't
really know -
my box that is following FreeBSD-11 Stable ran into a weird situation.
A set of files, especially `/lib/libjail.so.1` are in both states
`existing` and `not existing`:
I means:
david:~>cp ~david/libjail.so.1 /lib
cp: /lib/libjail.so.1: File exists
But:
david:~>ls /lib/libjail.so.1
ls: /lib/libjail.so.1: No such file or directory
david:~>find /lib -name "libjail.so.1" -print
/lib/libjail.so.1
david:~>find /lib -name "libjail.so.1" -ls
find: /lib/libjail.so.1: No such file or directory
With deeper investigation, the file is in fact mapped to an `inode`:
root@dmarec:~ # ls -di /lib
13 /lib
root@dmarec:~ # zdb -dddd zroot/ 13 | grep libjail.so.1
libjail.so.1 = 10552574 (type: Regular File)
Which fails with `zdb` on:
root@dmarec:~ # zdb -dddd zroot/ 10552574
Dataset zroot [ZPL], ID 21, cr_txg 1, 114G, 2570002 objects,

zdb: dmu_bonus_hold(10552574) failed, errno 2
`stat (2)` returns ENOENT when checking for the file:
david:~>truss stat -L /lib/libjail.so.1
...
stat("/lib/libjail.so.1",0x7fffffffe7e8) ERR#2 'No such
file or
directory' david:~>truss stat -L /lib/libjail.so.1
A pass with `zfs scrub` didn't help.
Any clue is welcome. What's that `dmu_bonus_hold` stands for ?
