What i don't understand is how files under /tmp/SUNWut/mnt/<login> are
managed? even if the usb pendrive isn't plugged, files are always here.
I deleted it with rm, but is there another way?
The directories under /tmp/SUNWut/mnt/<login> are mount points. Ideally, no
management is required. They should get removed when the device is unplugged
from the Sun Ray DTU or when the user's session gets disconnected from the
DTU.
In reality, these mount points will not get removed automatically if they
are busy when unmount is attempted by Sun Ray services. A mount point will
be busy if a process has it as its current directory. A busy UFS filesystem
will get forcibly unmounted & cleaned up, but not a PCFS filesystem (which
unfortunately is the most common), because Solaris PCFS does not implement
the "-f" option to umount(1M). These mount points will then go stale because
there's no corresponding device, and will remain on the system until the
administrator unmounts them when they're no longer busy and cleans up.
A stale mount point should be unmounted using umount(1M) first and then the
underlying directory can be deleted.
You can try to educate your users on using "utdiskadm -r" before unplugging
the device or hotdesking. It'll show an error message if umount fails and
the user can take steps (E.g. close an open filemanager window) to prepare
the device for unmounting.
This is can be really annoying to users as well as administrators. If
possible, please file an escalation with your Sun representative.
