Hello all, I've managed to get a bunch of 2Tb disks for setting up a few OSDs but before I even started adding them to my monitors, I decided to check my cluster state and noticed another OSD died.

Aborted (core dumped) There was no sign of hardware failure on kernel logs. I think, for now, I should move away from alpine binaries and use ceph's official containers. Is there any tool that can try to fix this rocksdb issue? Or is the recommended way to export all PGs from this osd and re-import on a new one? I agree that at this point I should consider rechecking all the hardware involved. I plan to decommission this system once I (if possible) I get the data out.

Hello Igor,
Just in case - didn't you overwrite existing PG replicas at target OSDs when exporting PGs back to OSDs 1&3?
Now that you mention that an OSD cannot have two shards, I think I did put myself now in a tricky place. I had 4 OSDs, two "died" .. leaving two online, so when I did export shards from osd.2 I did end up importing them in osd.3 (which had other shards for the same PG).
Doesn't look "that bad" ... (*looking up to the sky*) ... ## on osd.3 # ceph-objectstore-tool --data-path /var/lib/ceph/osd/ --op list-pgs | grep 16.b 16.bs1 16.bs0 (and the s2 should be in osd.1, s1 was imported)
## ceph health reports pg 16.b is down, acting [3,NONE,1]
I might have some spares HDDs to set up a new OSD (one though) with enough space for it to balance out, but as I've mentioned, there are quite a bunch of PGs in down state. Should I set-up a new OSD and wait until it "settles up"? The exported shards from the dead osd.2 that ceph health was complaining about sums to about 400Gb.
Is it possible to set-up an OSD and have ceph not push too many shards into it? (the replica pools are "small"). I ask this because it should be easy to get a 1Tb/2Tb disk, but if it should balance completely for the PGs to "unstuck", I need a bigger disk, which I don't have at the moment (and currently not the best market prices to get them).
Another option is if osd.0 is gone for good (the one that doesn't even allows me to run 'ceph-objectstore-tool --list-pgs'), I can wipe its disk/clone and use it instead, it is the same capacity as other OSDs (I used a spare I had at home). If you believe it is still workable, I can try to find some more disks and not touch those for the moment.
Thanks for the patience so far.

Hi Theo,
Sorry I can't tell for sure what would marking OSD lost do with its encryption keys. Likely - yes, they'll be lost.
But instead of going this way I'd rather suggest you to add another two OSDs and let Ceph recover more PGs replicas into them.
Just in case - didn't you overwrite existing PG replicas at target OSDs when exporting PGs back to OSDs 1&3? The same PG can't have two replicas/shards at a single OSD while your OSD count is pretty limited.. Just curious for now - that still shouldn't be an issue given you have at least 2 replicas/shards for all the pools anyway.
Thanks,
Igor

Hello Igor,
First of all, sorry about the late reply. It took me a while to export all shards that weren't available from the osd.2 (1 and 3 were fine, 2 didn't start but i could use `ceph-objectstore-tool ... --op list-pgs` while osd.0 I couldn't even list the pgs, it threw an error right away - more about it later in the email)
Two of the unavailable shards, when exporting, ceph-objectstore-tool core dumped with the same issue in the rocksdb, but I should have enough chunks to not need them - just mentioning in case is useful:

After importing all shards that I could recover that weren't available, I don't have any "unknown" pgs anymore. I still have lots of PGs in "down" state, which I assume I need to flag both "dead" OSDs as lost to unstuck them. Since it is an operation I cannot go back, I would like to confirm that is indeed the correct next step to take.
I have a few questions to understand "what happens" in the next step (marking osd as lost?):
Shall I assume that once I flag an OSD as lost, I won't be able to "activate" it since I use encryption when initializing the bluestore OSD, or flagging them as lost won't destroy their unlocking keys? (which means any hope of further extracting data to be gone, mostly on the osd.0 which I couldn't use ceph-objectstore-tool at all since the power loss).
I think I should have all the shards from the PGs but just in case, I've managed to make a clone of the osd.0 on a different physical disk (the other reason I took long to answer). But still ceph-objectstore-tool refuses to run:
# ceph-objectstore-tool --data-path /var/lib/ceph/osd --op list-pgs Mount failed with '(5) Input/output error'

Just as information, all except 2 pools in my cluster are "replicated". Pools id 11 and 16 are erasure coded (2+1). If I understood correctly, as long as I have two acting shards (and at most one "NONE"), data should be available (at least in read-only) once I mark the down OSDs as lost. Is that understanding correct?
Another information, pools 10 and 15 are the "replicated root pools" before the erasure coded pools were created.
Ignoring osd.0 for now, here are the current state of my cluster (mds is intentionally not started while I try to fix the PGs): ### ceph osd lspools 3 .rgw.root 4 default.rgw.log 5 default.rgw.control 6 default.rgw.meta 10 ark.data 11 ark.data_ec 12 ark.metadata 14 .mgr 15 limbo 16 limbo.data_ec 18 default.rgw.buckets.index 19 default.rgw.buckets.data ###

Once again, I cannot thank you enough for looking into my issue. I have the impression that being able to recover the data I need is just around the corner. Although the croit.io blog did mention flagging the osd as lost, I would like to double check it to avoid losing any
recover the data.
If there's anything further I could check or if you need full output of
(BlueStore::omap_get_values(boost::intrusive_ptr<ObjectStore::CollectionImpl>&, pgs possibility to the
commands, let me know.
Thanks in advance.

Hi Theo,
you might want to try to use PG export/import using ceph-objectstore-tool.
