Hello all
Seeking some help to solve below…
1. # ceph health detail
HEALTH_WARN 2 OSD(s) experiencing slow operations in BlueStore
[WRN] BLUESTORE_SLOW_OP_ALERT: 2 OSD(s) experiencing slow operations in
BlueStore
osd.10 observed slow operation indications in BlueStore
osd.21 observed slow operation indications in BlueStore
Having some other OSD’s with same size with more PG’s but only complaining on
below…
# ceph osd df |sort +17|egrep -i "^10|^21"
21 ssd 6.98630 1.00000 7.0 TiB 2.7 TiB 2.6 TiB 17 MiB 27 GiB 4.3
TiB 38.22 0.85 103 up
10 ssd 6.98630 1.00000 7.0 TiB 4.0 TiB 4.0 TiB 21 MiB 35 GiB 2.9
TiB 57.97 1.28 123 up
2. What does deviate means towards? holding higher number of pgs or Lower?
OSD osd.6 on host1 deviates by more than 30% from average PG count.
OSD osd.5 onhost2 deviates by more than 30% from average PG count.
# ceph osd df |sort +17|egrep -i "^ 5|^ 6”
5 ssd 6.98630 1.00000 7.0 TiB 2.8 TiB 2.8 TiB 11 MiB 32 GiB
4.2 TiB 39.91 0.88 97 up
6 ssd 6.98630 1.00000 7.0 TiB 3.2 TiB 3.1 TiB 19 MiB 48 GiB
3.8 TiB 45.65 1.01 103 up
