Free blocks. When using the traditional file system, adequate free blocks
are essential. A free block is a disk block that has no salvageable files
stored there. A file that has been both deleted and purged becomes free
space. Maintain a minimum of 1000 free blocks on each NetWare volume
that has suballocation enabled.
Suballocation, normally a low priority process, uses free blocks to
perform its function. When free blocks are low, suballocation can go into
an "aggressive" mode. Maintaining over 1000 free blocks will usually
avoid this problem.
To check how many free blocks you have on a volume, do either of the
following:
In NetWare Remote Manager, click Volumes in the navigation frame,
then click the Volume Information icon.
In MONITOR, from the Available Options menu, select Volumes >
the specific volume. Press Tab to view the free blocks information on
the Volume Information screen.
If there are not at least 1000 free blocks on the volume, access NetWare
Remote Manager, click Volumes in the navigation frame, click the
Volume Information icon for the applicable volume, and then click the
Purge Deleted Files button.
This removes all deleted files from the directories and subdirectories and
increases your free disk space.
If you have applications that create large numbers of temporary, files you
might want to set the P (Purge) flag on the directories where these files
are stored. Every temporary file that is created will be put on the deleted
file list. These files are kept on the disk until PURGE is run. You could
also run SET Immediate Purge of Deleted Files=On at the System
Console prompt.
Suballocation. The traditional file system uses a disk block size of 64
KB. It is very important to monitor the disk space. Novell Technical
Support recommends keeping 10% to 20% of the volume space free to
in NetWare Server Disks and Storage
