file system

[Shivkumar]

Dear Sirs,

We have file system mounted as shown below:-

/dev/vg00/lvol6 /var
/dev/vg00/lvol10 /var/opt/OV
/dev/vg01/lvol3 /var/adm/crash

If a file "test" is created as under:-
/var/logs/test
/var/opt/logs/test
/var/adm/logs/test

The file "test" would under which file system ?

Regards,
Shiv

Hi Shiv, the file "test" will come under /var FS since you create every "test" file under /var. Only /var/opt/OV and /var/adm/crash are different file system.

Hope this is clear.

Hi,

In your case it would be /var.
The simply way to check this is go to the folder (e.g cd /var/opt/logs..) then run "bdf ." which will show the file system under which the current folder is located.

You can as,

df

Example:

file is in /tmp then,

df /tmp/test
(/tmp...)


showing it is located in /tmp. You can as well as use ncheck utility.

Using ncheck utility as,

# ncheck -F

Get these informations from bdf as,

# bdf

Example:

# ncheck -F vxfs /dev/vg00/lvol4 | grep file1

Hi Shiv,
As others mentioned if you want to create
"test" file under /var/logs or /var/opt/logs
or /var/adm/log then it will locate
under /var
Just an advice,try to take a little bit care
while creating test files with the name "test" because unix systems have a command name test

baan01:/#whereis test
test: /usr/bin/test /usr/share/man/man1.Z/test.1

so you may accidently remove this file

Good Luck,

Hi,

All these will be under /var file system only. If the initial full path of the file matches any of other mount points then only it will be under that specific file system else it will be in parent file system and that is the case here.

Hi Shiv, you can use # du or df to find out which FS it resides.

Hi,

Also doing a bdf in a particular path will let you know which file system that directory belongs to. The files in the directory will also belong to the same file system.

#bdf .

You can use -xdev option donot cross file system so that you can find the file availablity as,

find /var -xdev -type f -name "filename"

change /var to your file system more.

-Muthu

[Arunvijai_4]

# find /var -local -type f -name "test" will also list "test" where it is.

hi shiv,

One easy way to know is to run command:

bdf test

e.g.
$ bdf /etc/hosts
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 204800 67664 136088 33% /
$



hope this helps too!

kind regards

same to bdf, use df command.

# df /stand/vmunix
first column /stand is showing the mount point.

ncheck utility is created to suit this.
