Best Practices
Partitioning
Allocate two to two and a half times the size of RAM to swap space.
Filesystems
-
Assign quotas to all users on all filesystems.
-
Monitor space with df, du, and quot (on Solaris).
-
Include meaningful comments in your /etc/[v]fstab file that document the physical devices associated with the system's logical designation (for example, above the entry for /dev/c0t1s2, add a comment that the disk is an external Fujitsu model "foo" with SCSI ID 3).
-
Document the following items in a file:
- Physical disk arrangement, including models, disk chain type and ID, and cable arrangements
- Logical disk arrangement, including devices and filesystem names
-
When complete, print the contents of the documentation file onto actual paper and store it in a central location (file cabinet). Remember that you don't want to lose the text file in the same disaster that ate your filesystem in the first place!
