Hi guys, I
deploy an efk cluster and use ceph as block storage in kubernetes, but
RBD write iops sometimes becomes zero and last for a few minutes. I set the debug_osd to 20/20 and checkeck the osd_logs.
I found that when iops becomes zero, Logs
like “get_health_metrics reporting 1 slow ops
...” will appear on two fixed nodes. I think there
is something wrong with these two node, like Linux
core version, ceph version or
disk problem.
Here is the config:
OS: CentOS Linux release 7.6.1810 (Core)
Linux 3.10.0-957.27.2.el7.x86_64
Ceph: 14.2.4
Disk: SSD
The log is in the attachment. Look forward to your reply, Thanks .
