Symptoms

Cloud storage cannot be mounted.

df shows :

df: `/pstorage/pcs1': Transport endpoint is not connected

It is impossible to unmount or remount /pstorage/pcs1 :

~# umount /pstorage/pcs1
umount: /pstorage/pcs1: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))

~# service pstorage-fs restart
Unmounting pstorage filesystems:  umount: /pstorage/pcs1: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))
                                                           [FAILED]

Meanwhile lsof shows nothing:

~# lsof 2>/dev/null | grep /pstorage/pcs1
~#

Cause

Cloud storage was unmounted incorrectly.

Resolution

Unmount it with '-l' option and restart pstorage-fs service - it will mount storage to the server :

~# umount /pstorage/pcs1 -l
~# service pstorage-fs restart
