- Assuming the machine is used primarily for news service, disk accesses to
- /usr/spool/news will greatly exceed all other disk io combined. It would
- therefore be better to also put the OS on the new disk to reduce disk
- accesses on the old disk.
-
- On our machine we have 3 disks that are allocated as follows.
-
- Disk 1 root file system, /usr and /usr/lib/newsbin
- Disk 2 /usr/spool/news and some rarely accessed archives
- Disk 3 /usr/lib/news, home directories and a few miscellaneous things
-
- One more way to reduce your disk accesses is to mount /tmp as a tmpfs
- (memory resident directory).
