Tapes

for looking what´s on the tape:
mt -f /dev/rmt/0mn fsf 1
tar tvf /dev/rmt/0m > /tmp/tar.index

LVM:
glue a splitted LV:
lvmerge -m ...

Tip for creation:
- first make little mirror, then expand both together. Seems to be faster.

Defrag:

fsadm is the main command. A lot of functions are only available with online-JFS.
Price of online JFS depends on hardware...from 2 to 12k€
BSP: fsadm -E -F vxfs -users
