Hi Somnath,
Thank you for your reply!!
The if script is:
[global]
#logging
#write_iops_log=write_iops_log
#write_bw_log=write_bw_log
#write_lat_log=write_lat_log
ioengine=rbd
clientname=client.admin
pool=ecssdcache
rbdname=imagecacherbd
invalidate=0
rw=randwrite
bs=4k
[rbd_iodepth32]
iodepth=32
The pool and rbd image names are correct.
Ceph -s from the rbd client and the monitor server both shows as:
cluster e414604c-29d7-4adb-a889-7f70fc252dfa
health HEALTH_WARN clock skew detected on mon.h02, mon.h05
monmap e3: 3 mons at {h02=
130.4.240.102:6789/0,h05=130.4.240.105:6789/0,h08=130.4.240.78:6789/0},
election epoch 3212, quorum 0,1,2 h08,h02,h05
osdmap e23689: 39 osds: 35 up, 35 in
pgmap v3174229: 16126 pgs, 8 pools, 132 GB data, 198 kobjects
545 GB used, 29224 GB / 29769 GB avail
16126 active+clean
I've also checked that connection to the monitor hosts from the rbd client
looks good too.
Really not sure what's going on..
Thanks in advance all!
Best,
Mavis
