I am preparing a replacement system for my 10 year old home firewall/nat/webserver.
The new system is i386 (amd 2600, 2.25 G RAM, 3x 120 GB HD), running NetBSD_6_Stable w/Generic kernel. I had 3 disks, so *loosely* followed Ch. 16 (raidframe setup) of The Guide. Initially I installed 6.1.4 release onto wd0, upgraded it to 6_Stable, configured raid on wd1/wd2 using the example config from the guide: START array 1 2 0 START disks /dev/wd1a /dev/wd2a START layout 128 1 1 1 START queue fifo 100 Now to my question.... I've already reconfigured wd0 as a raid disk, installed bootblocks with -t raid and verified I can use it in the array manually. But I think I'd like to add wd0 into raid0 as a hot spare. I can do this interactively, but it is not persistent. Is this as easy as updating the config file to: START array 1 2 1 START disks /dev/wd1a /dev/wd2a START spare /dev/wd0a START layout 128 1 1 1 START queue fifo 100 (raidctl -c config_file raid0) 1) It was not clear from my reading of the man page or guide, if I could reconfigure a raid array without destroying it. 2) If what I propose is OK, what other steps might I need or want to take? thanks, gene
