[dm-devel] Online disk size change and Linux



Sorry if this is off-topic... but if anyone could help, it'd be good.

Is Linux (more specifically Red Hat EL 5.4) able to recognize _disk_ size changes online? We have some HP servers with QLogic HBAs connected to an EVA 4000 Storage, with multipathing properly set up. These disks can be resized online, but only after a reboot that RHEL recognizes the change. I've been trying to find any information about it, but to no avail.

Regards,

Daniel Olops
