Hi Michel, This is not an issue. It's a new warning that can be adjusted or muted. Check this thread [1] and this part [2] of the Reef documentation about this new alert. Came to Reef with PR #59466 [3]. Cheers, Frédéric. [1] https://www.spinics.net/lists/ceph-users/msg86131.html [2] https://docs.ceph.com/en/latest/rados/operations/health-checks/#bluestore-sl...

Hi,
Since our upgrade to 18.2.6 2 days ago, our cluster is reporting the warning "1 OSD(s) experiencing slow operations in BlueStore":
[root@dig-osd4 bluestore-slow-ops]# ceph health detail HEALTH_WARN 1 OSD(s) experiencing slow operations in BlueStore [WRN] BLUESTORE_SLOW_OP_ALERT: 1 OSD(s) experiencing slow operations in BlueStore osd.247 observed slow operation indications in BlueStore
I have never seen this warning before so I've the feeling it is somehow related to the upgrade and it doesn't seem related to the regression mentioned in another thread (that should result in an OSD crash). Googling quickly, I found this reported on 19.2.1 with SSD where in my case it is an HDD. I don't know if the workaround mentioned in the issue (bdev_xxx_discard=true) also applies to 18.2.6...
Did somebody saw this in 18.2.x? Any recommandation? Our plan was, according to best practicies described recently in another thread to move from 18.2.2 to 18.2.6 and then from 18.2.6 to 19.2.2... Will 19.2.2 clear this issue (at the risk of others as it is probably not widely used)?
Best regards,
Michel _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
