Thanks to those who gave me some tracks as to put back dsk5 at its original
place but nothing has changed.
I've got a new disk, put it in original place where dsk0 was and the name is
now dsk6.
On this disk I've regenerated a system as described in Advfs Administration
Manual in copying the 2 filesystems from dsk5, modified the swap space
designation, modified the links for root_domain and usr_domain.
I've tried in single user mode and the problem is still there :
exec: /sbin/mount_advfs -F 0x14000 root_domain#root /
msfs_mount: The mount device does not match the linked device.
Check linked device in /etc/fdmns/domain
msfs_mount: Setting root device name to root_device RW
root_domain#root on / type advfs (rw)
There is absolutely no problem with the usr_domain filesystem :
root_device on / type advfs (rw)
/proc on /proc type procfs (rw)
usr_domain#usr on /usr type advfs (rw)
......
Does it mean that in the root file system there is something somewhere where
it's written that it has been created on dsk0 and now it's impossible to
change ?
Thank you for your help
Regards
Daniel
