Filesystem Corruption, Strange Issue

[KPKIND]

Dear All,

I have had a filesystem corrupted on one of the AIX 5.3 TL04 SP01 boxes and could not really find any underlying obvious reason, and IBM is currently looking in to the problem. They have requested me to capture the fsck data and send them for analysis. While doing this the cmd's I have executed are as below

fsck -n -o metacapture=/newfs/out1 <corrupted fs name>

My question here is the size of file capture1 in /newfs/out1 directory is 4GB+, but my filesystem is only 2G. I am really surprised how this has happened in the first place, secondly my df still reports only 1% of the space is used. Not sure since it is somekind of metadata, if it goes and uses the disk blocks directly, though they are not allocated to the filesystem.

root# df -g /newfs
Filesystem GB blocks Free %Used Iused %Iused Mounted on
/dev/fslv00 2.00 1.98 1% 6 1% /newfs
root# ls -l /newfs/out1
total 34288
-rw------- 1 root system 4626055168 Jul 07 15:33 capture1
root# df -g /newfs
Filesystem GB blocks Free %Used Iused %Iused Mounted on
/dev/fslv00 2.00 1.98 1% 6 1% /newfs
root#

Any inputs are really appreciated.

Pl let me know if you require any more information

TIA

Kpkind,

I have to admit that you have a very interesting problem!

Is /newfs/out1 a mounted file system on /newfs file system?

could you please try using:

du -sg /newfs

and du -sg /newfs/out1
