Problem with mounting a file system

Vipin Singhal — Wed, 07 Dec 2005 15:12:18 GMT

Hi,
I have created the PV,VG,LV & File system.. successfully

But when i am mounting these file systems...
I am able to mount all the file systems except one, under same VG

This is the error:
mount -F vxfs /dev/vg5/vipin /vipin
vxfs mount: /dev/vg5/vipin is corrupted. needs checking.

Please suggest what to check?
thanks
Vipin

Run "fsck -y /dev/vg5/vipin"

file system larger then device - means a device is missing - IE - there should be 4 disks in the lvol - but only 3 are visible by the host - that is - the first disk with the VTOC knows that the size is say 100GB - but there is only 75GB of disks...

Can also be caused by doing say a lvreduce prior to resizing the file system with fsadm...

I cannt reduce my LV size,
should i extend the VG size by adding a new LUN?

Can I delete this logical volume if yes how can I?

You can remove this logical volume by doing:

umount /vpin

lvremove /dev/vg5/vipin,
but please be aware this will destroy all data on this logical volume if you have nay located here.

Okay..not to worry...

How was /dev/vg5/vipin created?

Do you still have /dev/vg01/vipin?

Are you trying to create a new file system so you can copy the data over?

If so, to remove:

lvremove /dev/vg5/vipin

then create it again:

lvcreate -L 4096 -n vipin /dev/vg5

If that works, then:

newfs -F vxfs /dev/vg5/rvipin

then:

fsck /dev/vg5/rvipin

then mount it (unles the old vipin is already mounted in same place):

mount /dev/vg5/vipin /vipin

Hi,

There is no need to recreate the LV for this. You can find the size of the lvol and see if any disk is missing from it.

#lvdisplay -v /dev/vg05/vipin

You should not see any stale PEs.

In the even of everything OK you can just do a newfs on the device file instead of recreating everything all over.

HTH,
