In case it helps, it is recognizing the partitions, sdd2 and sdb2 the new RAID is to be assembled from: hendrik@april:~$ ls /dev/disk/by-path/ -l total 0 lrwxrwxrwx 1 root root 9 Jan 6 20:40 pci-0000:00:0d.0-scsi-1:0:1:0 -> ../../sr0 lrwxrwxrwx 1 root root 9 Jan 6 20:40 pci-0000:00:0e.0-scsi-1:0:0:0 -> ../../sdd lrwxrwxrwx 1 root root 10 Jan 6 20:40 pci-0000:00:0e.0-scsi-1:0:0:0-part1 -> ../../sdd1 lrwxrwxrwx 1 root root 10 Jan 6 20:40 pci-0000:00:0e.0-scsi-1:0:0:0-part2 -> ../../sdd2 lrwxrwxrwx 1 root root 9 Jan 6 20:40 pci-0000:04:09.0-scsi-0:0:0:0 -> ../../sda lrwxrwxrwx 1 root root 10 Jan 6 20:40 pci-0000:04:09.0-scsi-0:0:0:0-part1 -> ../../sda1 lrwxrwxrwx 1 root root 10 Jan 6 20:40 pci-0000:04:09.0-scsi-0:0:0:0-part2 -> ../../sda2 lrwxrwxrwx 1 root root 10 Jan 6 20:40 pci-0000:04:09.0-scsi-0:0:0:0-part4 -> ../../sda4 lrwxrwxrwx 1 root root 9 Jan 6 20:40 pci-0000:04:09.0-scsi-2:0:0:0 -> ../../sdb lrwxrwxrwx 1 root root 10 Jan 6 20:40 pci-0000:04:09.0-scsi-2:0:0:0-part1 -> ../../sdb1 lrwxrwxrwx 1 root root 10 Jan 6 20:40 pci-0000:04:09.0-scsi-2:0:0:0-part2 -> ../../sdb2 lrwxrwxrwx 1 root root 9 Jan 6 20:40 pci-0000:04:09.0-scsi-3:0:0:0 -> ../../sdc lrwxrwxrwx 1 root root 10 Jan 6 20:40 pci-0000:04:09.0-scsi-3:0:0:0-part1 -> ../../sdc1 lrwxrwxrwx 1 root root 10 Jan 6 20:40 pci-0000:04:09.0-scsi-3:0:0:0-part2 -> ../../sdc2 lrwxrwxrwx 1 root root 10 Jan 6 20:40 pci-0000:04:09.0-scsi-3:0:0:0-part4 -> ../../sdc4 hendrik@april:~$ And it does recognize the other partitions, sdd1 and sdb1, outside the RAID, that reside on those disks. I can mount them and they have their proper contents. So it is detecting the gpt partitioning properly. -- hendrik -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
