Disks

The installed disk

The 1.1 images hold four partitions: the root, swap, the boot store and /home (the layout). In Amix the disk at SCSI id 6 is c6d0, and its partitions are slices:

• /dev/dsk/c6d0s1: the root (/dev/rdsk/c6d0s1 is the same slice, raw);
• /dev/dsk/c6d0s2: swap;
• slice 3: the boot store, used only by the boot loader and kbootset;
• slice 4: /home.

/etc/vfstab lists what is mounted at boot, one line each, in seven columns: the device, the raw device to check, the mount point, the file-system type, the check pass, mount at boot, options. For example the root:

/dev/dsk/c6d0s1 /dev/rdsk/c6d0s1 / ufs 1 no -

Sizes

• A file system holds at most 2047 MiB. On a bigger disk, make more partitions.
• A single file can be up to 2 GiB.

Adding a disk

There is no tested way yet to add a second disk to a 1.1 system.

• On the A3000's own SCSI, a second disk has stopped Kickstart 3.2 from booting the first one: do not add one there.
• On a 68030 without a floating-point unit, making a ufs file system fails with Bad System Call.
