Hi all,
After updating to 10.2.9, some of our SSD-based OSDs get put into "down"
state and die as in [1].
After bringing these OSDs back up, they sit at 100% CPU utilization and
never become up/in. From the log I see (from [2]):
heartbeat_map is_healthy 'OSD::osd_op_tp thread 0x7f1cfad0d700' had
timed out after 1
before they ultimately crash.
Stracing them, I see them chewing on omaps for a while and then they
seem to do nothing, but CPU utilization is still quite high.
I downgraded (inadvisable, I know) these OSDs to 10.2.7 and they come
back happily. I tried setting debug_osd = 20, debug_filestore = 20,
debug_ms = 20, debug_auth = 20, debug_leveldb = 20 but it didn't seem
like there was any additional information in the logs.
Does anyone have any clues how to debug this further? I'm a bit worried
about running a mix of 10.2.7 and 10.2.9 OSDs in my pool.
For what it's worth, the SSD OSDs in this CRUSH root are serving CephFS
metadata. Other OSDs (spinners in EC and replicated pools) are
completely OK as far as I can tell. All hosts are EL7.
Thanks,
Lincoln
