Re: osd not removed from crush map after ceph osd crush remove

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

 



I think this happened because of the wrongly removed OSD...
A bug maybe ?

Do you think that "ceph pg repair" will force the remove of the PG from the missing osd ?
I am concerned about executing "pg repair" or "osd lost" because maybe it will decide that the stuck one is the right data and try to do stuff with it and discard the active running copy ......

Dimitar,

I would agree with you that getting the cluster into a healthy state first is probably the better idea.  Based on your pg query, it appears like you're using only 1 replica.  Any ideas why that would be?

The output should look like this (with 3 replicas):

osdmap e133481 pg 11.1b8 (11.1b8) -> up [13,58,37] acting [13,58,37]
