[SunHELP] Root file system 100% full

[Murali Kanaga]

Solaris 7 Gurus'

Here is a problem that I am having lately:

This on a E250 running Solaris 2.7 with the following patches
Generic_106541-04 

The OS disk (9GB) lay out is as follows:

	/dev/dsk/c0t9d0s0     192833  192130       0   100%    /
	
	/dev/rdsk/c0t9d0s1	2GB for SWAP
	/dev/dsk/c0t9d0s3    2055705 1343380  650654    68%    /apps
	/dev/dsk/c0t9d0s4     722449  509266  155388    77%    /opt
	/dev/dsk/c0t9d0s5     241403  170674   46589    79%    /var
	/dev/dsk/c0t9d0s6    1018382  578211  379069    61%    /usr
	/dev/dsk/c0t9d0s7    2312592  959074 1307267    43%    /home
	
Couple of weeks ago, the root file system (/) became 100% full). It used be
23% full prior to that.

Here is the scnerio:

The du & df may not show the same results:

I ran du -adk | sort -rn, It reports only 38.5mb is used.

1. 	I re-booted the system with CD-rom, then ran an fsck on this slice,
there were no bad blocks, 0.0% 	fragmentation. Then, mounted this as /a, ran
a df -k /a, it said 100% full.
	There were no process is running, when I booted the system with
CD-ROM, why the df -k is 100% full?

2.	I ran find, any big files & could not find any!!

Your help is appreciated!

Thanks,
