How to do at the /proc size becoming large observed by 'du -ks' command

I am using Solaris 8, I found the /proc is becoming large, it is almost 40GB, one of the diectory is about 20GB, it is oracle server process ID,

root@db1/#du -ks /proc

384020240/proc

root@db1/#cd /proc

root@db1/proc#du -ks 18563

2040106318563

root@db1/proc#

how can I do at such condition, will it occupy /root filesystem space? Will it backup also into tape by using 'ufsdump'?

Thank you!

Its a virtual filesystem. Files there take up no space.You should avoid backup it up.Its a seperate filesystem. I believe you have to specifically set each filesystem to be backup up with ufsdump. So don't backup that one.

TKS. However, I wonder which command can show the real size of / file system?

#df -k /

Filesystemkbytesusedavail capacity Mounted on

/dev/vx/dsk/bootdg/rootvol

61968156 13969126 4737934923%/

#du -ks /

450749798

As you can see, I only have about 60 GB, but 'du' will count 450 GB!

Will ufsdump backup /proc also?

The number out of df is the real size.

du recurses down across filesystem boundaries so will count all filesystems on the machine.

Not just /

And as I said before ufsdump only backs up one filesystem.

So for example if you have a / filesystem

And another filesystem mount us /usr/local

and another mounted as /proc.

the a ufsdump of will just get /, not /proc or /usr/local

Just as a 'by the way', du -dwill *not* cross FS boundaries.du / gives complete system (because it recurses)du -d /gives root only.
