I can't resize a disk image which is not mounted without shutting down my linode. It fails with "Linode must be shutdown before resize".

Is it a bug or that's the way this is intended?

At the bottom of the configuration form:

"Your Linode must be shutdown before issuing a resize."

I know that. I'm just saying that an unmounted disk should be resizable without shutting down my linode.

If it's part of the currently booted profile then the kernel would need to be told of the new "physical" size of the disk. It's not enough for the disk to be unmounted. On real machines this works with hotswap devices (eg SATA, USB). Dunno if Xen can be made to do it.

The thing is that the second image is an exact clone of the first one (sort of like a backup). "df -k" cannot even "see" the second image; it only shows one (/dev/xvda). Is it still not possible to resize the second image?

If the disk is in the profile then the kernel still knows the disk there, even if userspace doesn't. Look at /proc/partitions and the unused disk shows up...

Yeah I guess you are right:
'cat /proc/partitions' wrote:
major minor #blocks name

202 0 8192000 xvda
202 16 262144 xvdb


This is the end of it then, I'll update the thread title.
