lots of Timeout message
What system parameter settings are unreasonable for ceph 14.2.0 ?
Updated by Nathan Fish almost 5 years ago
Has there been any progress on this? If not, can it be moved to 14.2.3? This is one of 2 issues blocking 14.2.2 and there are a lot of important bugs fixed in 14.2.2.

Hi Nathan,
The problem still exists, cluster ceph version 14.2.1 (d555a9489eb35f84f2e1ef49b77e19da9d113972) nautilus (stable), I checked the official website of ceph. The latest release version is 14.2.1. I have not found the updated release version. What am I missing?
Thanks for your reply.

14.2.2 has indeed not been released yet, that's the problem. This is one of two issues which are listed as blocking the release of 14.2.2:
https://tracker.ceph.com/versions/574
14.2.2 has multiple important bug fixes which I would like to put into production soon. So I would like to know if this issue is nearly done, or if it can be moved to 14.2.3 so 14.2.2 can ship.
Updated by Lei Liu almost 5 years ago
Of course, but I don't have no permission to modify, I think this problem may be caused by the operating system settings, currently not resolved, the administrator can close this issue.
Will test while v14.2.2 released.
