Re: Quincy: HDD OSD slow restart

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Luis,

I think this is caused by the issue covered by https://tracker.ceph.com/issues/53266

Gabi is working on that AFAIK.

You might want to verify my hypothesis by setting fast_osd_shutdown to false and checking startup times afterwards.

Not sure it makes sense to use that setting permanently though as I'm unaware about all the consequences.


Thanks,

Igor

Hi all,

We have installed Qincy 17.1.0 on our lab cluster. The update from Pacific 16.2.6 went quite smoothly, but now we have a weird issue.

Everytime we want to restart some OSD running on HDD, they take about 6 minutes to be up, and we have this error on the logs:

```

2022-03-02T12:41:45.863+0000 7f5857f463c0 -1 bluestore::NCB::__restore_allocator::Failed open_for_read with error-code -2
2022-03-02T12:47:54.225+0000 7f5857f463c0 -1 osd.13 21874 log_to_monitors true2022-03-02T12:47:54.882+0000 7f58479d8700 -1 osd.13 21929 set_numa_affinity unable to identify public interface '' numa node: (2) No such file or directory

```

The same error can be found on OSD running on SSDs, but there is no delay, the OSD starts within 10 seconds.
