Why do my volumes mount so slowly?
Four factors cause long volume mount times:
1) The Volume Directory Tables are very large.
During the lifetime of a volume, files and directories are created and
deleted. When a file is deleted, the contents of the file are not removed
from the volume. These files are saved in a manner that allows for
recovery. Periodically, system administrators should purge a volume of
Purging a volume removes purgable files, but does not decrease the size
of the directory tables. After a purge, a volume is left with a
large number of directory blocks that are empty. This does however,
decrease the number of files that NetWare must process.
The size of the Directory Tables needs to be reduced. Currently the
only method to decrease the size of the Directory Tables is to backup the
volume, delete the voume, recreate the volume and then restore the volume.
In a future release, we will add the capability to automatically reduce
the Directory Table size.
2) The Directory Tables are scattered (fragmented) all over the
This will increase the length of time that it takes NetWare to read the
directory tables by a large amount.
Use our Volume Defrag and perform a "Quick Defragment". This
will defragment the Primary and Secondary Directory Tables.
3) The directory blocks within the directory tables were fragmented.
A directory block is 4KB in size and contains 32 file entries. Most
NetWare volumes use a 64 KB block size. If a directory has more than 32
file entries, then additional directory blocks are allocated to a
directory. On a typical system, the directory blocks are probably
scattered around the directory tables and are not contiguous requiring
multiple disk reads to process a directory.
Use our Volume Defrag and perform an "Defragment Directory
Entries". This will sort the Directory Blocks within the Directory
Tables requiring fewer disk reads and disk seeks to process a Directory
4) Not enough system memory.
If your system does not have enough free memory to hold both the
primary and secondary tables in memory during a volume mount, then the
same data may need to be moved into memory several times.
Either add more memory to your system, or reduce the size of the
