Hi Olivier,
what size does the cache tier have? You could set cache-mode to
forward and flush it, maybe restarting those OSDs (68, 69) helps, too.
Or there could be an issue with the cache tier, what do those logs say?
Regards,
Eugen
Zitat von Olivier Bonvalet <ceph.list@xxxxxxxxx>:
Hello,
on a Luminous cluster, I have a PG incomplete and I can't find how to
fix that.
It's an EC pool (4+2) :
pg 37.9c is incomplete, acting [32,50,59,1,0,75] (reducing pool
bkp-sb-raid6 min_size from 4 may help; search ceph.com/docs for
'incomplete')
Of course, we can't reduce min_size from 4.
And the full state : https://pastebin.com/zrwu5X0w
So, IO are blocked, we can't access thoses damaged data.
OSD blocks too :
osds 32,68,69 have stuck requests > 4194.3 sec
OSD 32 is the primary of this PG.
And OSD 68 and 69 are for cache tiering.
Any idea how can I fix that ?
Thanks,
Olivier
