AIX

Hello
On AIX 5, In a file system - I see no big files but still df shows no space available. What is tricky here?

Filesystem GB blocks Free %Used Iused %Iused Mounted on
/dev/fslv10 20.00 6.11 70% 2167 1% /data/d2

I have calculated all files conumption under this FS using 'ls -lR' and total I can view files available not more than 1.5 G then where is rest 12 GB

Any ideas?

you possibly have a file that is open by a process but the handle has been deleted.

have a look at your ps listing - see if anything jumps out, or try trawling through /proc with find looking for any processes using large files

Another possiblity would be that the file is invisible. Files which names start with a dot (".example", for example) would not be listed by ls as long as you do not specify the "-a" option. (Except for root: ls is always implying -a for root.) The same is true for directories.

also check

fuser /dev/fslv10

ps -ef |grep <process>

it may be consuming the space
