mounting the file system under /opt

[Shivkumar]

Is it possible to mount /opt logical file system under 2 volume group /dev/vg00/lvol5 and /dev/vg00/lvol6 ?

Thanks,
Shiv

Shivkumar, I think You should read the manuals once again...

/opt: filesystem
/dev/vg00/lvol5: logical volume
/dev/vg00/lvol6: logical volume
/dev/vg00: volume group

You can increasize the space allocated for /opt by first increasing the logical volume and then the filesystem.

if that is what You wanted, check if You have free space in vg00 by issueing vgdisplay /dev/vg00 | grep Free

Hi

From ur question i believe u want to mount /opt mount point to mount two lvols ...

Two lvols cannot be mounted on a same mount point. If u try that way u will get the error messae
vxfs mount: /dev/vg_x_/lvolx is already mounted, /opt is busy,or allowable number of mount points exceeded

If u want to get the data , then mount one lvol get the data and then unmount and mount the other lvol

Shiv,

An lvol coresponds to one and only one /dev/vgxx/lvoly and belongs only to one volume group.

Either increase the lvol if you are short on disk space or mount another lvol in a sub directory of /opt (eg /opt/omni) where yo want to perform a new installation and you require more disk space.

best regards,
Kurt

Hello Shiv,

You can not mount 2 logical volumes to the same mount point.

Incase if you want to lvol5 and lvol6 on /opt then you can do the following.

First mount the lvol5 on /opt
Then create a new directory on /opt after mounting lvol5. Then you can mount lvol6 to that subdirectory /opt/

But ensure /opt is the one which is mounted first, after that you mount /opt/

_{Hope this helps}

Hi Shiv

One flie system can be mounted to only one Logical Volume so it not Is it possible to mount /opt logical file system under 2 volumes

Shiv,

No it is not possible...
As Florian's description ;
/opt: filesystem
/dev/vg00/lvol5: logical volume
/dev/vg00/lvol6: logical volume
/dev/vg00: volume group

And also have a look at my attachment
which illustrates vg-lv-pe...

Good Luck,

Hi Shiv,

Only one filesystem can be mounted on any logical volume.
Attached is the document which would clear your concepts regarding the LVM.
