Ceph集群增加Mon時(shí)出錯(cuò)：

admin_socket: exception getting command descriptions: [Errno 2] No such file or directory
INFO:ceph-create-keys:ceph-mon admin socket not ready yet.
admin_socket: exception getting command descriptions: [Errno 2] No such file or directory
INFO:ceph-create-keys:ceph-mon admin socket not ready yet.

手動(dòng)起一下
root@pve01://etc/pve/priv# /usr/bin/ceph-mon -f --cluster ceph --id pve01 --setuser ceph --setgroup ceph
2020-10-20 17:46:42.194667 7fb035114100 -1 error: monitor data filesystem reached concerning levels of available storage space (available: 4% 4.46GiB)
you may adjust 'mon data avail crit' to a lower value to make this go away (default: 5%)

看到原因了，，
mon 所在服務(wù)器，硬盤容量要求大于5%，，這個(gè)機(jī)器的根要滿了，，刪掉20g數(shù)據(jù)后，，啟動(dòng)正常
