Hi Ramin! The SAM-QFS file system disk cache needs it's own mountpoint, say /samqfs/samqfs01 and you need additional mountpoints for your NFS mounted file systems which are to be used for disk archiving - this is /mnt/nfs in your case. You cannot create a SAM-QFS file system on top of an NFS mounted file system, just on raw devices.
