There are 3 types of file system -
A] Disk based file system (pcfs, ufs, udfs, hsfc)
B] Distributed file system (nfs, autofs, cachefs)
C] Pseudo files system (virtual file system, memory based
file system, swapfs, procfs, mntfs, dev, & tmpfs)
for CD-ROM-default mount point is /cdrom/cdrom0, ro for
#mount -F hsfs -o ro <dev name> <mount point>
#mount -F hsfs -o ro /dev/dsk/c0t1d0s0 /cdrom/cdrom0
for DVD-ROM-default mount point is /cdrom/cdrom0, ro for
#mount -F udf -o ro <dev name> <mount point>
#mount -F udf -o ro /dev/dsk/c0t1d0s0 /cdrom/cdrom0
for floppy-device name is /dev/diskette0
#mount -f pcfs <dev name> <mount point>
#mount -F pcfs /dev/diskette0 /dir1
nfsd; statd; lockd; mountd; for server
and for clients are statd; and lockd
The path to see the shared memory
/usr/sbin/sysdef | grep SHMMAX
VTS stands for Validation and Test Suite which is used to

may be many zombie process are running or harware error,
ps -el is a command to check any zombie processes are
running, if is the issue then issue preap command to kill
the multiple zombie processes, if it a hardware error then
issue iostat -en command to see the hardware errors.
If you want to use the 20gb free space in that file system,
bring the system to single user mode and then take the
entire backup of that file system . Then format the file
system using newfs /dev/rdsk/c#t#d#s# after mount the file
system using mount command and restore the backup then you
can use the 20gb free space.
