Dear, We have a couple of GPFS fs, gpfs mount on /gpfs and gpfs2 mount on /gpfs/external, the problem is the mount path of the second fs sometimes is missied I am trying to mmumount this FS in order to change the mount path. but I cann't. If I make a mmumont gpfs2 or mmumount /gpfs/external I get this error: [root at gpfsgui ~]# mmumount gpfs2 Wed Jan 27 14:11:07 CET 2021: mmumount: Unmounting file systems ... umount: /gpfs/external: not mounted (/gpfs/external path exists) If I try to mmchfs -T XXX , the system says that the FS is already mounted. But there is no error in the logs. Any Idea? Regards, I -------------- next part -------------- An HTML attachment was scrubbed...
