Extending root file system by VxVM

[jhuihuihi]

I've RP5405 and file system configured by Veritas FIle System (VxVM). Now, I want to increase /opt from 800MB to 1.5GB.
Both of CLI and vmsa reporting error when i did increasing /opt.
Does /opt can be resized online ? or must be in single user like LVM ?
Any suggestion ?

Thanks,

Jhui

/opt may be configured as contiguous. You may need to change that setting prior to expanding it.

Jhui,

VxVM is Veritas Volume Manager, not the Veritas Files System (usually shortened to VxFS, and also known as JFS on HP-UX).

There should be no problem extending the volume that the /opt filesystem is on, but once the volume has been extended, the filesystem must also be extended, and this may be where your problem is. If you don't have the *full* version of Veritas file system (usually appears as 'OnLine JFS' in a swlist listing), then the filesystem can't be extended online. To extend the filesystem in this situation it must be unmounted, which usually means going to single user mode for /opt as many system daemons access this filesystem.

Of course if you told us what the error message you are getting is, it might clarify this.

Incidentally /opt is not normally created as a contiguous volume.

If /opt is a Online JFS(Adv JFS product), you can increase it online. I mean; without unmounting /opt and in multi user mode.
You can use the command

#fsadm for this purpose. Pl check the man page of FSADm for details.

to check the manpage of fsadm with online JFS product installed i think you have to type: man fsadm_vxfs.

Still keep in mind the remark of SEP, because it won't even extend with onlineJFS when the volume is configured contiguous.
