I need to explain this a bit more:
If you start with empty disks, eg. 2 disks I put them together in bios of raid controller. After booting install media, which runs dmraid -ay during boot process, i get something like that: /dev/mapper/nvidia_fffadgic because no partitions are there.
Tobias, that's correct. I put them together in the bios, and then I just partition them as normal when the Arch installer ask me what partitions I want.
Now i cfdisk this device, are the nodes updated then? - I mean do i get the /dev/mapper/vidia_fffadgicp1 p2 p3 autimatically or do I need to run dmraid -ay for every partition i created?
That - I don't know. I know that all the nodes were updated during the 1st boot after upgrading to 1.0.15rc, but I haven't looked since. Next time I'm at the machine, I'll boot and see. I think you will need to run dmraid -y each time, but I will confirm.
- Also what happens if partitions are deleted?
I haven't tried that yet. Remarkably, cfdisk doesn't show the 'p' anywhere in the partition listing. So it looks like the 'p' is strictly a creature of dmraid: cfdisk (util-linux-ng 2.14.2) Disk Drive: /dev/mapper/nvidia_ecaejfdi Size: 750156372992 bytes, 750.1 GB Heads: 255 Sectors per Track: 63 Cylinders: 91201 Name Flags Part Type FS Type [Label] Size (MB) ---------------------------------------------------------------------------------------------------------- nvidia_ecaejfdi5Boot Logical Linux ext3 20003.85 * nvidia_ecaejfdi6 Logical Linux ext3 123.38 nvidia_ecaejfdi7 Logical Linux ext3 39999.54 nvidia_ecaejfdi8 Logical Linux swap / Solaris 1998.75 Pri/Log Free Space 688028.23
