How to remove a placement group?

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

 



Hi all,

 

I’m currently having trouble with an incomplete pg.

Our cluster has a replication factor of 3, however somehow I found this pg to be present in 9 different OSDs (being active only in 3 of them, of course).

Since I don’t really care about data loss, I was wondering if it’s possible to get rid of this by simply removing the pg. Is that even possible?

 

I’m running ceph version 0.94.3.

 

Here are some quick details:

 

1 pgs incomplete

1 pgs stuck inactive

100 requests are blocked > 32 sec

 

6 ops are blocked > 67108.9 sec on osd.130

94 ops are blocked > 33554.4 sec on osd.130

 

pg 15.3b3 is stuck inactive since forever, current state incomplete, last acting [130,210,148]

pg 15.3b3 is stuck unclean since forever, current state incomplete, last acting [130,210,148]

pg 15.3b3 is incomplete, acting [130,210,148]

 

Running a: “ceph pg 15.3b3 query” hangs without response.

 

I’ve tried setting OSD 130 as down, but then OSD 210 becomes the one keeping things stuck (query hangs), same for OSD 148.

 

Any ideas?
