But a disk dedicated to vtapes should be doing a lot of sequetial accesses: once it has been formatted and the slots have been assigned, it is writting files the size of one Amanda's chunk. In fact, that would be worth a study: the disk usage for vtapes vs. normal disk usage. That is just gross figures but: Users' home directories: Filesystem Size Used Avail Capacity Mounted on /dev/da1p1 2.9T 851G 1.8T 31% /home 2565312 files, 223129681 used, 556890331 free (564355 frags, 69540747 blocks, 0.1% fragmentation) Amanda vtape disk: Filesystem Size Used Avail Capacity Mounted on /dev/ada5p1 2.6T 2.2T 269G 89% /automnt/ada5 475 files, 582393950 used, 127171372 free (84 frags, 15896411 blocks, 0.0% fragmentation) The vtape disk is slightly older than the users' home, definitely fuller and less fragmented, so I would guess big sequetial files with little head movement. Good luck with your health. Olivier
