[SunHELP] a question

[Gary.Siao at bmo.com]

michael

a good system administrator always knows that it is not a very very good
thing to only have 1 partition (/). there are a lot of disadvatages if you
setup your solaris servers with only 1 partition...

it is a good practice to have  /   /usr   /var  /opt   as a separate
partition.... /export/home can be part of root partition or can be a
separate partition.

cheers !

this situation has changed and the standard from sun has changed with
it.
while in the old days this was certainly true, what sun training, sun
support, and our sun service provider tells us is that it is no longer
required.
while working on solaris, sun made changes to increase the reliability
of the os.

if you check the filesystem changes (mentioned in a previous post), you
will seen one of the changes.

It is not advisable to only create one / partition, if your logs, or
mysql databases, or anything else for that matter starts creating large
files (and you dud not set any quotas) the / partition would fill up and
no new processes will be started,

"/" = the root directory.
   this partition would contain
       /, /usr, /opt, /home, /export, /bin, /var, /tmp

a "swap" = the swap partition

example: 18GB hard drive would have

     c0t0d0s0 = 16gb mounted on "/"
     c0t0d0s1 = 2gb used as swap

most workstation installs have a rather large /export/home when sun
configures them. if your machine is an application server, a separate
/export/home is unncessary. if your machine hosts home directories, a
separate /export/home or nfs mounts would probably be useful.

solaris 8, 9, 10 (& maybe 7) will boot.

in the old days, a partition could reach 100" full.
this did not permit anything to be written to the filesystem. this was
changed several years ago so that solaris would boot.

sun now recommends a / and a swap for disks.

this is probably a stupid question,  but what happens if the root
directory fills up.  I understand that willnot be bootable. Curious as
to exactly why.

thanks
Joan
