storageos ls：无法访问“卷”：传输端点未连接

Question

我正在尝试清理和重新部署存储，但不知怎的，我得到了这个奇怪的错误。

slave1 storageos # pwd
/var/lib/storageos
slave1 storageos # ls -la
ls: cannot access 'volumes': Transport endpoint is not connected

d??????????  ? ?    ?       ?            ? volumes
slave1 storageos # rm -rf volumes 
rm: cannot remove 'volumes': Is a directory
slave1 storageos # uname -a
Linux slave1 4.14.88-coreos #1 SMP Mon Jan 7 23:48:02 -00 2019 x86_64 Intel(R) Atom(TM) x5-Z8330 CPU @ 1.44GHz GenuineIntel GNU/Linux
slave1 storageos # 

有什么建议如何消除这个？

实际上手动卸载此dir消除了此错误

slave3 storageos # df
df: /var/lib/storageos/volumes: Transport endpoint is not connected
Filesystem      1K-blocks    Used Available Use% Mounted on
devtmpfs           964768       0    964768   0% /dev
tmpfs              985804       0    985804   0% /dev/shm
...
slave3 storageos # umount /var/lib/storageos/volumes
slave3 storageos # df
