Hi,
I have an zpool as shown below. The /murex filesystem is used as NFS share to 3 other Solaris servers. Many files and directories are created and deleted in this shared folder on daily basis.

Things were running fine until this week and few application processes were unable to complete due to space constraints.

bash-3.00# df -h /murex
Filesystem                      size   used  avail capacity  Mounted on
murexcommonpool        196G   115G    81G    59%    /murex

bash-3.00# du -sh /murex
  13G   /murex

bash-3.00# lsof | grep deleted
bash: lsof: command not found
bash-3.00#

df and du command shows huge difference in the used space. How to reclaim the space (around 100G)  in /murex file system that are consumed by the system processes belonging to hosting and other Solaris servers using this NFS share?

Howdy, Stranger!
