Hi,
After recreating some related OSDs (3, 71 and 237), now the acting set is
normal but the PG is incomplete now and there are slow ops on primary OSD
(3). I have tried to make it normal
Hi Lazuardi,
I assume this pg is in a EC 4+2 pool, so you can lost at most 2 OSDs?
Now you have wiped the data of 3 OSDs, this pg does not have enough
information to recover the content in it.
If it is the case, I guess unless you can recover the data in some of
these recreated OSDs, you cannot recover the content in this pg. Your
best choice may be deleting all objects in it (with
"ceph-objectstore-tool --op remove", then "ceph osd force-create-pg", I
believe). Be aware of the data loss.

with osd_find_best_info_ignore_history_les way but the PG is still
incomplete. On this condition the I/O from clients sometimes is freezing, I
suspect that the blocks inside this PG cause I/O freeze. How can I resolve
this incomplete PG or at least to make the client I/O not freeze for
recovering the rest of the normal block like recovering the drive with bad
sectors?
Best regards,

Hi,
Suddenly we have a recovery_unfound situation. I find that PG acting set
is missing some OSDs which are up. Why can't OSD 3 and 71 on following PG
query result be members of PG acting set? Currently, we use v15.2.8. How to
recover from this situation?
