cannot unmount : Block device required

[TTr]

> bdf o/p is not showing the device file name.. srange!
Not really. The device name is too long and it is on a separate line before the grep-ed line.
Do you have any cascaded mount points under /MyFS or are you exporting any subdirectories (and are mounted on other systems) under /MyFS?
Check the status of the vgxMyEnv with vgdisplay and of the logical volume lvol01 with lvdisplay and with "ll /dev/vgxMyEnv/lvol01"

Your fstab file is probably wrong. A block device is /dev/dsk/, but you probably have /dev/rdsk/. The /dev/rdsk directory is for raw devices. When you umount by mountpoint name, the fstab file is consulted to fond the actual device file (the first field). Do not use grep with bdf. Insteas, tell bdf exactly what you want to see:

bdf /MyFS

bdf will split lines that are too long but grep does not know this. What does the above command report?

You might also want to show the MyFS line in /etc/mnttab.
