Short update on the issue:
Finally we're able to reproduce the issue in master (not octopus),
investigating further..
@Chris - to make sure you're facing the same issue could you please
check the content of the broken file. To do so:
1) run "ceph-bluestore-tool --path <path-to-osd> --our-dir <target dir>
--command bluefs-export
This will export bluefs files to <target dir>
2) Check the content for file db.wal/002040.log at offset 0x470000
This will presumably contain 32K of zero bytes. Is this the case?
No hurry as I'm just making sure symptoms in Octopus are the same...
Thanks,
Igor

Hi Igor
I've sent you these directly as they're a bit chunky. Let me know if
you haven't got them.
Thx, Chris

Hi Cris,
could you please share the full log prior to the first failure?
Also if possible please set debug-bluestore/debug bluefs to 20 and
collect another one for failed OSD startup.
Thanks,
Igor

I'm getting similar errors after rebooting a node. Cluster was
upgraded 15.2.1 -> 15.2.2 yesterday. No problems after rebooting
during upgrade.
On the node I just rebooted, 2/4 OSDs won't restart. Similar logs
from both. Logs from one below.
Neither OSDs have compression enabled, although there is a
compression-related error in the log.
Both are replicated x3. One has data on HDD & separate WAL/DB on
NVMe partition, the other is everything on NVMe partition only.
Feeling kinda nervous here - advice welcomed!!
Thx, Chris
