prevent large volumes from mounting. As soon as possible, upgrade the
system to a newer board that can access higher memory. For instructions
on using the SETcommand, see
instructions on using MONITOR, see
Use a driver that supports scatter gather functionality.
Provide at least one device large enough to hold a core dump of the
server's memory. A core dump cannot span devices.
If a volume is comprised of two or more segments, each segment should
be on a different disk. If the volume is made of more than one segment on
one disk, the volume spans between the two segments, slowing
performance.
If you use file compression, make sure you enable the option at a time
when there is little server activity.
For example, make sure that the Deleted Files Compression Option
parameter is not set to 2, which would cause compression whenever a file
is deleted but not purged. Make sure that users have not flagged their
directories IC, which enables immediate compression. Use the SET
command to make sure that compression is scheduled to start and stop at
the appropriate times.
You can enable fault tolerance protection by mirroring or duplexing the
SYS volume, because it contains the core NetWare files. See
and Duplexing Partitions" on page
Keep 10% free space in any NetWare volume, except SYS where there
should be 20% free space.
WARNING:
Do not fill up your SYS volume. This could damage your entire file
system. The Transaction Tracking System, which protects NDS
compromising the NDS replicas on the server.
To keep enough free space on volumes, try the following suggestions:
Use MONITOR to check each volume's disk space regularly.
Use the Volume Low Warning Threshold parameter to specify when
you will be warned that a volume is running out of disk space. Set the
parameter in MONITOR. For instructions on using MONITOR, see
MONITOR in Utilities Reference.
Move any user files or print queues to another volume.
Don't store replicas on servers with low disk space.
