umount error - cannot umount : block device required
I show it mounted in /etc/mnttab. If I run bdf I can see it as one of the file systems mounted. However if I run bdf /v01 then it shows up under /, which implies it is just a directory. If I cd into /v01 there is nothing in it. However, when you run the bdf (for everything) /v01 will show about 50k of data. I need to export the volume group but I can not until I get this 'unmounted'.

Re: umount error - cannot umount : block device required
fuser -cuk /v01
kills all processes on the filesystem.
Now you can umount.
You can not umount a filesystem while your session is sitting in it.
cd out of the directory first.
IF that doesn't work, consider reboot.

Re: umount error - cannot umount : block device required
I'd suspect the mnttab file is corrupt.
Move or rename it & run mount - that'll rebuild it.
It sures sounds like it's not physically mounted other than the mnttab entry.
HTH,
Jeff
