I'm in the process of porting d-i to a number of NAS devices that can hold 2 or 4 disks. The long standing problem of persistent disk naming is thus an issue for me. Since the hardware in those NAS devices doesn't change, I was thinking that controller-host would be a good idea to identify a disk, i.e. which controller a disk is connected to.
On my machine I see the following: foobar:/dev/disk/by-path# ls -la total 0 drwxr-xr-x 2 root root 240 Jan 1 01:00 . drwxr-xr-x 5 root root 100 Jan 1 01:00 .. lrwxrwxrwx 1 root root 9 Jan 1 01:00 platform-sata_mv.0-scsi-0:0:0:0 -> ../../sda lrwxrwxrwx 1 root root 10 Jan 1 01:00 platform-sata_mv.0-scsi-0:0:0:0-part1 -> ../../sda1 lrwxrwxrwx 1 root root 10 Jan 1 01:00 platform-sata_mv.0-scsi-0:0:0:0-part2 -> ../../sda2 lrwxrwxrwx 1 root root 10 Jan 1 01:00 platform-sata_mv.0-scsi-0:0:0:0-part5 -> ../../sda5 lrwxrwxrwx 1 root root 10 Jan 1 01:00 platform-sata_mv.0-scsi-0:0:0:0-part6 -> ../../sda6 lrwxrwxrwx 1 root root 9 Jan 1 01:00 platform-sata_mv.0-scsi-1:0:0:0 -> ../../sdb lrwxrwxrwx 1 root root 10 Jan 1 01:00 platform-sata_mv.0-scsi-1:0:0:0-part1 -> ../../sdb1 lrwxrwxrwx 1 root root 10 Jan 1 01:00 platform-sata_mv.0-scsi-1:0:0:0-part2 -> ../../sdb2 lrwxrwxrwx 1 root root 10 Jan 1 01:00 platform-sata_mv.0-scsi-1:0:0:0-part3 -> ../../sdb3 lrwxrwxrwx 1 root root 10 Jan 1 01:00 platform-sata_mv.0-scsi-1:0:0:0-part4 -> ../../sdb4 foobar:/dev/disk/by-path# Do people think this would be a reasonable approach, or is a generic solution finally coming forth? -- Martin Michlmayr http://www.cyrius.com/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
