Subject: object unfound before finish backfill,up set diff from acting set
To: ceph-users@xxxxxxxx
Hi,guys
my cluster face a network problem so it occur some error.after solve
network problem.
latency of some osds in one node is high,using ceph osd perf,which come to 3000+
so I delete this osd from cluster,keep osd data device.
after recover and backfill,then I face the problem describe in
title.ceph health detail is :
pg 4.438 is active+recovering+degraded+remapped, acting [7,11], 1 unfound
pg 4.438 is stuck unclean for 135368.626141, current state
active+recovering+degraded+remapped, last acting [7,11]
recovery 1062/4842087 objects degraded (0.022%); 1/2028378 unfound (0.000%)
root@node-67:~# ceph pg map 4.438
osdmap e42522 pg 4.438 (4.438) -> up [34,20,30] acting [7,11]
I can see the pg data in deleted osd.6,which have some different with
the existing osd.7 and osd.11
can I copy the pg data to the new up set? ignore acting set?
some info is below,the output of pg query is the attachment.
