Online JFS

Pete Devlin — Thu, 28 Mar 2002 09:50:29 GMT

Hey everyone!
kind of a strange question but here goes..... I need to extend a filesystem on the fly (I should have created it as 8 Gb but didn't the disks are all in the VG). I know we can use Advanced Vxfs. This particular machine only has the standard VXFS (mirror UX). We have a licence for Advanced VXFS earmarked for another box but not yet installed. My question is
if I install Advanced VXFS & extend the file system Online then remove the Advanced VXFS, will it cause a problem or will 'standard' vxfs continue to handle the file system as
normal?
Cheers

If I remember correctly installing Online JFS requires a reboot so its probably not worth the trouble. You're going to have an outage either way, so you might as well just shutdown the application, unmount the filesystem and extend it normally.

Steve

Hi,

In my opinion this is not the best way.
As you will install On-line JFS you will have to install kernel patches as well.
So you have to reboot anyway.

I would not suggest to remove On-line JFS afterwards you will get stuck with left overs in kernel and patches.

Pete,

Thanks, but I will succeed some day.
Might be today if someone asks a nice question.

Clemens, I think you just earned 4 points :)

Harry is only 26 point away from 10000. Halfway to his leaf-hat
