Quantum 3.5.2 Marine Sanitation System User Manual


 
Allowance for Special Characters
StorNext User’s Guide 337
The best rule of thumb is to use a 16K FsBlockSize unless other
requirements such as directory ratio dictate otherwise.
This setting is not adjustable after initial file system creation, so it is
very important to give it careful consideration during initial
configuration.
Example:
FsBlockSize 16K
JournalSize Setting 1
The optimal settings for JournalSize are in the range between 16M and
64M, depending on the FsBlockSize. Avoid values greater than 64M due
to potentially severe impacts on startup and failover times. Values at the
higher end of the 16M-64M range may improve performance of metadata
operations in some cases, although at the cost of slower startup and
failover time.
The following table shows recommended settings. Choose the setting that
corresponds to your configuration.
This setting is adjustable using the
cvupdatefs utility. For more
information, see the
cvupdatefs man page.
Example:
JournalSize 16M
Allowance for Special Characters
In prior StorNext releases, the StorNext GUI would sometimes operate
incorrectly when encountering files whose names contained certain non-
standard characters: single quotation marks and characters with ASCII
values less than 32, such as tab stops and carriage returns.
