Hi Managers,
I am having a problem dumping the root file system to tape. I am
running Unix 4.0F on a DEC workstation.
The command I type is :
$ dump 0uf /dev/nrmt0h / and I get the following error message:
ugems9.sbg.spel.se 1: dump 0uf /dev/nrmt0h /
dump: Dumping from host ugems9.sbg.spel.se
dump: Date of this level 0 dump: Mon Jul 10 10:27:44 2000 MET DST
dump: Date of last level 0 dump: the start of the epoch
dump: Dumping root_domain#root (/) to /dev/nrmt0h
dump:
dump: Cannot open file-system file root_domain#root
dump: Bad file system specification or bad file system. The raw device must
dump: be entered when the file system's pathname has not been entered in the
dump: fstab file. A bad file system is reported when the the magic number
dump: is not found in the super block.
main(): open(): No such file or directory
dump: The ENTIRE dump is aborted
Now the entry in fstab file for root is
/dev/rz16b swap1 ufs sw 0 2
root_domain#root / advfs rw 1 1
/proc /proc procfs rw 0 0
usr_domain#usr /usr advfs rw 1 0
/dev/rz27a /files ufs rw 1 3
My next step was to look in the fdmns directory for the diretory to each
domain.
They both existed and the entries for /usr and / were as follows
rz16a_at_ -> /dev/rz16a (in the /etc/fdmns/root_domain/. dir)
rz16g_at_ -> /dev/rz16g (in the /etc/fdmns/usr_domain/. dir)
My question is , "Is it safe to do the following command "dump 0uf
/dev/nrmt0h /dev/rz16a" and aslo for the usr device.?
I have looked at all books and man pages and nothing is really mentioned on
it. My main concern is root being advfs and not ufs, that is why I didn't
experiment and go ahead and do it. I had looked in the O'reilly book and it
did say that on a system supporting multiple fileysytem types, dump may be
limited to UFS (BSD-type) filesystems.
Stephen.
