NOTE: In the examples that follow, user details, cluster names, hostnames, directory paths, filenames, etc. represent a fictitious sample (and are used to provide an illustrative example only). Any similarity to actual persons, or entities, living or dead, is purely coincidental and not intended in any manner.

 

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
...
