Hi fellow admins,
I've been searching (without any luck) for the steps how to lower the
reserved space of the file systems, here is an example:
Filesystem size used avail capacity Mounted on
/dev/md/dsk/d0 9.6G 7.2G 2.3G 76% /
/dev/vx/dsk/datadg/voldb1 64G 51G 6.8G 89% /db1
/dev/vx/dsk/datadg/voldb4 32G 26G 2.5G 92% /db4
/dev/vx/dsk/datadg/voldb2 128G 114G 1.7G 99% /db2
/dev/vx/dsk/datadg/voldb5 64G 18G 40G 32% /db5
/dev/vx/dsk/datadg/voldb3 64G 51G 6.9G 88% /db3
...
..
As you may see, the numbers doesn't correspond if you do the math!,
taking as anexample db3
size = 64G (100%)
used = 51G ( 79% real but listed 88%)
avail = 6.9G (11% aprox.)
I know that the 10% "lost" is for integrity info, but it's a lot!!
No matter it's a Veritas VM volume, SVM volume or a single slice volume
it reserves the 10%!
Uname -a output:
SunOS srvdb 5.9 Generic_118558-25 sun4u sparc SUNW,Sun-Fire-880
How can I lower this value of 10%?
Thanks in advance,
