Extending /var filesystem using FSADM

[Navin_3]

Hi everybody,

I wanted to extend /var filesystem.Is it possible. I tried using fsadm utility & not able to do that. I have online JFS installed on my server. Pls let me how i can do this.

Below is the fsadm error i got.

root@holland>fsadm -F vxfs -b 888832 /var
vxfs fsadm: /dev/vg00/rlvol8 is currently 786432 sectors - size will be increased
vxfs fsadm: write failure at block 5083134 : No such device or address

Hi Navin,

Have you extended your logical volume using lvextend before running fsadm?

Rgds,

Did you extend logical volume with lvextend first?

# lvextend -L /dev/vgxx/lvolxx
# fsadm -b M /var

How much free space is available in root vg?
Can you pls post the output of
#vgdisplay vg00

Please check:

bdf /var

And make sure, that /dev/vg00/rlvol8 is bigger than 868MB

[Alex Lavrov.]

Sorry, not bigger. I mean not less than 868MB.

Hi Navin,

I should have mentioned that I think your syntax for fsadm looks ok at first glance so I'm not exactly sure why it's failing.

write failure at block 5083134 suggests to me that the logical volume isn't big enough or that its having problems writing to the disk at that point for some reason.

The other thing that might be worth checking is your patches for OnlineJFS.

If everything checks out and all else fails you might have to try shutting down to single user mode and trying it then. Obviously thats last resort though as you have online jfs and should be able to do it while the systems up.

Cheers,
Anthony

I gave the size in Mb & it was accepted.

fsadm -b 868M /var
fsadm: /etc/default/fs is used for determining the file system type
vxfs fsadm: /dev/vg00/rlvol8 is currently 786432 sectors - size will be increased

Thanks all
