serviceguard + sap umount errors

[anat heilper]

Hi,
have anyone encountered problems with sap of umount the file systems that are related to it?
I've tried to increase the fs_umount_count parameter, but this doesn't seems to help either, the umount fails.

Thanks,
Anat

hi anat ;

after closing the sap instance , you should kill the process by fuser -ck /mountpoint.

Hi Hasan,
this is done by serviceguard umount_FS function which issues fuser command before it tries to umount the file systems.

it is possible to paste related log file portion ( /etc/cmcluster/packetnam/*log )

Node "X": Unmounting filesystem on y:/export/sapmnt/Z
WARNING: Running fuser to remove anyone using the file system directly.

tnhis message returns several times ( the number of times that the parameter fs_umount_count is set) and then the package fails to halt

I cannot locate nfs_umount or nfs_unmount functions in any the HP-sourced toolkit files in /opt/cmcluster. What is the source of this function?
