I have a server with hot swap disks.
I'd like to be able to swap out a non-system disk , eg /dev/sdd and
put in a new
disk, partition it in fdisk, then mount those partitions. This all
works fine, I can partition it,
but the linux kernel hangs on to the old disk partitions in memory, so
I can't mke2fs or
mount the newly created partitions, without doing a reboot.
Is there a way to force the kernel re-read the partition tables on a
non-system disk?
How do people maintain high uptime, if you need to reboot every time
just to see an extra
disk in a hot swap system?
If no oone else answers here, there are lists and sites dedicated to
HA Linux systems.
