Hi, I have setup with software raid1:
1. Partitioning 2 disks with a "a" / partition, a "b" swap partition and a "d" partition for the rest of the disk 2. Creating the softraid raid1 device for both "d" partition with bioctl 3. Partitioning for everything else than / in the softraid device (including an altroot partition) 4. Installing the system 5. Copy the first disk "a" partition on the second disk "a" partition with dd (dd if=/dev/rsd0a of=/dev/rsd1a) 6. Make the second disk bootable: /usr/mdec/installboot -v /mnt/boot /usr/mdec/biosboot sd1 7. Reboot Everything is booting well, except that "/" fails to be remounted read/write. I figured out it's because both disks has the same duid, I manually changed the duid of one disk. Now everything runs fine, / is remounted read-write. I also added the second swap partition to fstab. So what would you recommend for a softraid mirror setup? my setup works fine, but I'm not really happy with this manual fix of the duid. Another question. I read about softraid that booting on it is not supported, is it true for raid1 too? A disk part of raid 1 may probably a safely mounted read-only during boot (I know linux software raid is able to do this). My last question is about swap, I read in the documentation that RAM dump are written to the swap partition in case of system crashes and that, of course, the amount of swap should be greater or equal to the amount of RAM. Must the RAM dump fit into one swap partition, or could it be splitted in e.g. 2 swap partitions? Thanks Michel
