hi all,
today , I ceph cluster has soming wrong! one of my mdss is loaggy!
#ceph -s
health HEALTH_WARN 1 is laggy
I restart it
# scrvice ceph -a restart mds.1
It is ok at first! but a few Minutes latter!
#ceph -s
health HEALTH_WARN 0 is laggy
2 mds can not work at the same time! one is health ,abt another is laggy!
How can I solve this promble.。
by the way ! I found when I typed the
# ceph osd dump
...
max_mds 1
...
Is the filed max_mds cause this problems ! in my ceph.conf , the max_mads , which values is 2 , lays in the [global] section！
thinks
peng
