i have a computer with was running freebsd 3.1Release with 6 scsi disks
with an fstab like:
# Device Mountpoint FStype Options Dump Pass#
/dev/da0s1b none swap sw 0 0
/dev/da0s1a / ufs rw 1 1
/dev/da0s1e /u01 ufs rw 1 1
/dev/da1s1e /u02 ufs rw 1 1
/dev/da2s1e /u03 ufs rw 1 1
/dev/da3s1e /u04 ufs rw 1 1
/dev/da4s1e /u05 ufs rw 1 1
/dev/da5s1e /u06 ufs rw 1 1
/dev/cd0c /cdrom cd9660 ro,noauto 0 0
proc /proc procfs rw 0 0
i just upgraded to freebsd-3.2release.
for doing that i disconnected five of the disks from the computer
booted from fbsd3.2 cdrom, did a newfs on / with a fresh install
and everything is working fine. my fstab is now:
# Device Mountpoint FStype Options Dump Pass#
/dev/da0s1b none swap sw 0 0
/dev/da0s1a / ufs rw 1 1
/dev/cd0c /cdrom cd9660 ro,noauto 0 0
proc /proc procfs rw 0 0
then i did:
mount /dev/da0s1e /u01
and everything is still ok.
i connected my five other disk, again and wanted to do:
mount /dev/da4s1e /u05
but this gives me: device or file not found.
in /dev i made ./MAKEDEV da4 which created some da4 files
(see listing below), but no device /dev/da4s1e was created.
i tried a mount on every device
but only /dev/da4c /dev/da4e /dev/da4s1 work.
but before writing my firstbyte on the disk
i want to be sure of the correct device-name for mounting my disk, because
some years ago on ultrix, i mounted a disk with a wrong device-name and
it was very interesting to see how the filesystem was destroyed within
several hours. I also had a bad experience when upgrading from
freebsd 2.2.1 to freebsd 2.2.7 with device names of ide-disks.
i have a backup, but restoring 80GB takes some time.
thank you for any help.
