Symptoms

Checking prerequisites before an upgrade when removing the shareddir the umount command may return "not found" or "not listed".

# dcli -C umount /opt/shareddir
/opt/shareddir was not found in /proc/mounts
/opt/shareddir was not found in /proc/mounts
/opt/shareddir was not found in /proc/mounts
/opt/shareddir was not found in /proc/mounts
/opt/shareddir was not found in /proc/mounts
/opt/shareddir was not found in /proc/mounts
/opt/shareddir was not found in /proc/mounts
/opt/shareddir was not found in /proc/mounts
/opt/shareddir was not found in /proc/mounts
/opt/shareddir was not found in /proc/mounts
umount: /opt/shareddir: not mounted
/opt/shareddir was not found in /proc/mounts
/opt/shareddir was not found in /proc/mounts
umount: /opt/shareddir: not mounted
/opt/shareddir was not found in /proc/mounts
/opt/shareddir was not found in /proc/mounts
/opt/shareddir was not found in /proc/mounts
/opt/shareddir was not found in /proc/mounts
umount: /opt/shareddir: not mounted

 

Note:  Investigating  /proc/mounts may show a line indicating '/opt/shareddir' is deleted like:

/opt/shareddir\040(deleted)


The expected output for '/opt/shareddir' in  '/proc/mounts' is like:

...
auto_direct_bda /opt/shareddir autofs rw,relatime,fd=19,pgrp=10883,timeout=300,minproto=5,maxproto=5,direct 0 0
...
bdanode03.example.com:/opt/exportdir /opt/shareddir nfs4 rw,relatime,vers=4,rsize=1048576
...


Rather than:

...
auto_direct_bda /opt/shareddir autofs rw,relatime,fd=19,pgrp=11717,timeout=300,minproto=5,maxproto=5,direct 0 0
...
bdanode03.example.com:/opt/exportdir /opt/shareddir\040(deleted) nfs4 rw,relatime,vers=4,rsize=1048576
...
