Mounting Filesystem

Rafael Casero — Wed, 14 Jun 2006 19:45:12 GMT

I have a 100 gig disk presented to me for the SAN.

I did the following steps: I still can not mount it please advise what I'm doing wrong.

mkdir /od/dg01
mkdir /dev/vg01
ioscan -fnC disk
pvcreate /dev/rdsk/c14t0d0
vgcreate vg01 /dev/dsk/c14t0d0
mknod /dev/vg01/group c 64 0x010000
lvcreate -L 100000 -n dg01 vg01

miaux10: / =>mount /dev/vg01/dg01 /od/dg01
/dev/vg01/dg01: unrecognized file system

Please help....

Well - you need to mknod before the vgcreate and you need to newfs the lvol

Hi Rafael:

The manpages for 'newfs' will direct you, but:

# newfs -F vxfs /dev/vg01/dg01

This will create a JFS (VxFS) filesystem whose size is equal to the logical volume container size.

Regards!

For some reason is not working for me

miaux10: / =>newfs -F vxfs /dev/vg01/dg01
UX:vxfs newfs: ERROR: V-3-21623: /dev/vg01/dg01 is not a character device

Hi Rafael:

Oops! I meant to specify the *raw* (character) device:

# newfs -F vxfs /dev/vg01/rdg01

Regards!

You must use the character (raw) device file when creating a new filesystem. The raw device file has the letter 'r' in front. So the synat would be:

newfs -F vxfs /dev/vg01/rdg01

If you list the volume group directory, lvcreate will create a pair of device files with different major numbers (raw and cooked).

You guy's are the best...

That did it.

Thanks, guy's this is my first time doing this, our Unix admin just got up and left so I offered to take the position.

So I'm pulling my hairs.

Hello Rafael,

I know that the post is closed, however I noticed that the FS size is 100GB and when you did the newfs, it was done without the
-o largefiles option, this might cause issues when trying to create / copy files larger than 2GB. You correct the slip using fsadm command.

#fsadm -F vxfs -o largefiles /dev/vg01/dg01

If it fails then you have to do a newfs..

# newfs -F vxfs -o largefiles /dev/vg01/rdg01

But you will loose data with the newfs command.

regards
