问题描述
在磁盘已满的情况下，Ceph卡住了，但是在修复之后，cephfs mds长时间处于重新连接状态。
Ceph -s的输出被截断了：
cluster:
id: (deleted)
health: HEALTH_WARN
1 filesystem is degraded
services:
mon: 6 daemons,deleted
mgr: deleted(active,since 3h),standbys:
mds: fs:2/2{fs:0=mds1=up:rejoin,fs:1=mds2=up:rejoin} 1 up:standby
osd: 9 osds: 9 up (since 3h),9 in (since 6w)
data:
pools: 10 pools,849 pgs
objects: deleted
usage: deleted
pgs: 849 active+clean
我已经检查了mds1的日志，上面写着mds.0.cache Failed to open ino 0x101 err -116/0。
有人可以帮我修复mds并使fs健康吗？
