Yeah, md+mdadm can do all this right now, provided the hardware and
driver support is there...
Yes, my point however is for low budget stuff with software raid the driver
support is not yet there in a vanilla kernel.
I can't just whack a sata drive off one of my promise SATA150-TX4
controllers, pop another one in and have the kernel rescan the partition
table and realise a new drive was present. (YET!)
I'm sort of confused... which are the combinations that allow me to hotswap a
disk w/ software raid. I don't mind doing some mdadm operations, I'm just
interested in how I can avoid rebooting.
I thought I couldn't, now I learn you can "provided the hardware and driver
support is there"... can you detail a little more?
Yup. Currently, SCSI has the hardware and driver support.
SATA has the hardware support, but not the driver support (Yet).
