Posting a quick update.
I ran a "zdb -emm" command to figure out what was going on, and it blew
up in my face with an abort trap here :
- vdev 0 has 145 metaslabs, which are cleared without any problems.
- vdev 1 has 145 metaslabs, but fails in the middle :
metaslab 32 offset 20000000000 spacemap 289 free 1.64G
segments 19509 maxsize 41.7M freepct 2%
metaslab 33 offset 21000000000 spacemap 303 free 11.9G
error: zfs: allocating allocated segment(offset=3D2335563722752 size=3D10=
24)
Abort trap(core dumped)
Converting offset 2335563722752 from earlier kernel panic messages gives
: 21fca723000, which matches the broken metaslab found by zdb.
Is there anything I can do at this point, using zdb?
It just sounds surrealistic I have ONE broken metaslab (seemingly?) and
that I can't recover anything...
Cheers,
