ONCplus B.11.31.13 Release Notes (5900-1979, March 2012)

Cause
When the command is executed to shut down the SRP daemon, it may initiate the NFS client
shutdown while there are active NFS mount points present in the SRP environment. Due to this, the
srp -stop command may hang while waiting for the active NFS filesystems to unmount.
Workaround
• Before issuing the command, it is recommended to verify whether the NFS mount point in the
SRP environment is active, by executing the fuser -c command on the NFS mount point
from the global view of SRP.
# fuser -c /var/hpsrp/srp01/opt/nfstest
where:
/var/hpsrp/srp01/opt/nfstest is an NFS mount point under the SRP environment
srp01
This command displays the process ids (PIDs) of the active processes on the NFS mount point.
/var/hpsrp/srp01/opt/nfstest: 11352c
where:
11352 is the PID of the active process on the NFS mount point
If there are no active processes on the NFS mount point, then execute the command. Otherwise,
wait until there are no active processes.
• If the srp -stop command has already been executed and it hangs, force unmount all the
NFS filesystems under the SRP instance which is being shutdown.
# umount -f /var/hpsrp/srp01/opt/nfstest
This unblocks the srp -stop command and allows it to complete the operation.
NOTE: Doing a force unmount may cause data loss for open files. After the unmount is complete,
if a program tries to access files from an unmounted filesystem, it will get an EIO error.
