The NMIS Self Test settings may need to be adjusted if the nmis8/var directory is running at a high rate of usage.  Look for the following attributes in nmis8/conf/Config.nmis:

• 'selftest_min_diskfree_percent' => 10
• 'selftest_min_diskfree_mb' => 25

When creating the RAM disk the size parameter may be a number expressed with the suffix k, m or g (kilo, mega, and giga).  It may also be expressed with the % sign.  For example if you'd like to allow the ramdisk to consume up to 25 percent of the available RAM the following technique could be used.

mount

-t

tmpfs

-o

size=25%

tmpfs

/media/ramdisk

Keep

in

mind

that

the

ramdisk

will

not

immediately

consume

the

amount

of

RAM

specified.  

This

is

the

most

it

will

be

allowed

to

consume

should

it

need

to.

Also

keep

in

mind

that

if

the

RAM

is

oversubscribed

the

ramdisk

could

be

pushed

into

swap. 

If

the

ramdisk

find's

itself

in

swap

space

it

defeats

the

purpose

of

this

expedition,

so

do

try

to

avoid

this

situation.
