Scan for new disk on Centos
I added a new disk image in the Linode Manger which I was expecting to see at /dev/xvdc but it doesn't show. I guess I need a reboot but I'd prefer not to just now.
I saw on other forums that centos can be signalled to scan for a new SCSI disk using this command:
echo "- - -" > /sys/class/scsi_host/host0/scan
but I don't have these directories because AFAIK the linode images are using a virtual disk manager not SCSI. Does anyone know of an alternative way my centos image can be triggered to recognise the newly created disk?
