Hello,
We just had our servers fitted with more disks. Most of the disks are growing existing RAID 1+0 channels, some are in new channels. Controllers and disks support live installation.
I'd like to avoid a reboot just to let the system find that the disks are larger.
All I can find so far suggests that its possible to rescan the disks, and even find the new geometry (e.g. http://linux.derkeiler.com/Mailing-Lists/Kernel/2004-12/1555.html) but nobody knows how to actually convince the system to let me use the extra space without a reboot.
Does anyone know of a way to achieve this?
Thanks,
--Amos
