Hi,
I am trying to following the instructions given in the OSF/1 V2.0
system administrator manual to back up the file systems "/" and "/usr"
and then restore it to a different Alpha, but came across some
problems. I suspect there is something missing somewhere.
Basically, on an Alpha 3000/300lx, I backed up the file systems
as follow:
1. shutdown in standalone mode: /sbin/shutdown now
2. check all disks are not mounted: /sbin/umount -a
3. /sbin/fsck -o /dev/rz3a
4. dump -0uf /dev/nrmt0h /
It completed in 3 minutes.
5. dump -0uf /dev/nrmt0h /usr
It took 20 minutes.
At the end, I rewound the tape, and did a restore -t
it read out the tape header (no tape label, but did indicates the dump
on /dev/rz3a), and then displayed the files under the / directory.
Now then I tried to restore the file contents onto another Alpha
(3000/300) as follow:
a. boot off the system from the OSF/1 CD
b. MAKEDEV /dev/rz2 ! build a system onto an external SCSI disk, unit 2.
c. disklabel -rw /dev/rrz2 ufs
disklabel -re /dev/rrz2
and set the partitions as: a: 400000 0 ! for /
b: 400000 400000 ! for swap
c:4194685 0
d: 0 0
e: 370000 3800000 ! for /data
f:1500000 2300000 ! for /home/mod6
g:1500000 800000 ! for /usr
d. newfs /dev/rrz2a
e. mount /dev/rz2a /mnt
f. cd /mnt
No errors so far.
g. restore -Yrf /dev/nrmt0h
then I get the error:
cannot stat dump file: No such file or directory
No file is restored.
I also tried restore -Yrf /dev/rmt0h but get the same error.
Is anyone has any idea?
Many thanks in advance.
Regards,
Peter Chiu
