I've got Lenny installed on a Sun Enterprise 4500. When I list partitions with
fdisk, I get duplicate entries, almost as if fdisk is recursing down into slice
3 on all dislabels or something, reading the partition table from that as well.
Furthermore, it freaks out about the first disk, which was partitioned and
formatted by the installer:
thwomp:/mnt# fdisk -l

Some background info, the first disk is on the built-in esp scsi, and was
partitioned manually with the installer, and formatted with same. The second
two disks are both fibre channel and are on an Emulex PCI card in a PCI I/O
module. I created partition tables on them manually with fdisk later, and
formatted them myself. Now, this duplicate partition table thing isn't a big
problem, except that is messes with the RAID. Here's a couple of other disks I
have:
Disk /dev/sdd (Sun disk label): 64 heads, 32 sectors, 8637 cylinders
Units = cylinders of 2048 * 512 bytes
Device Flag Start End Blocks Id System
/dev/sdd1 1 8637 8843264 fd Linux raid autodetect

Disk /dev/sdn (Sun disk label): 64 heads, 32 sectors, 8637 cylinders
Units = cylinders of 2048 * 512 bytes
Device Flag Start End Blocks Id System
/dev/sdn1 1 8637 8843264 fd Linux raid autodetect
/dev/sdn3 0 8637 8844288 5 Whole disk
Disk /dev/sdn3 (Sun disk label): 64 heads, 32 sectors, 8637 cylinders
Units = cylinders of 2048 * 512 bytes
Device Flag Start End Blocks Id System
/dev/sdn3p1 1 8637 8843264 fd Linux raid autodetect
/dev/sdn3p3 0 8637 8844288 5 Whole disk
These 11 disks are all part of a software RAID array. They were all
partitioned/formatted on this box, and are all fibre channel disks. I can start
the array just fine, and all goes well. But if the machine is shut down and
brought back up, when the kernel goes to detect and assemble arrays, I get a
recursive loop on the console where the kernel detects that the superblock on
/dev/sdn1 is too similar to the superblock on /dev/sdn3p1 (gee, I wonder why).
I have to power off the fibre channel box, allow the kernel to get past the
raid autodetect, then power it back on. Once that's done, I can re-assemble the
array manually.
