<color><param>0100,0100,0100</param>My problem is the following: 


<color><param>0000,0000,0000</param>After rebooting I get the next message for my 2 vinum-partitions: 

BAD SUPER BLOCK: MAGIC NUMBER WRONG 


I think it has something to do with the disklabeling, but I am not  

sure. 


I have FreeBSD 4.2 

========================================= 

I will tell you what I have done: 


I start a new FreeBSD install with 2 identical drives. 

I setup the first drive as full use and bootable (+only FreeBSD) 

I setup the second identically, but not bootable. 


My labels are: 

ad0:	/		2G 

		/a		rest of disk 

ad1:	swap	2G 

		/b		rest of disk 


I do a complete install with ports and linux binaries. 


I restart and do:  

# disklabel -e ad0         

(I have to note that in /root/.cshrc I changed my default editor from 
vi to ee, so  the alteration of the disklabel is done in ee) 


At the bottom I change the name of only e: from 4.2BSD in vinum 

(I leave a: as 4.2BSD) 


When I do disklabel -e ad0 again, I see, that the numbers for fsize, 
bsize and  bps/cpg have disappeared. Maybe this is what creates 
the problem? 


I do # disklabel -e ad1 

At the bottom I change the name of only e: from 4.2BSD in vinum 


I create the /etc/vinum.conf file as following: 


drive drive1 device /dev/ad0s1e 

drive drive2 device /dev/ad1s1e 

 volume usr 

  plex org concat 

    sd length 9g drive drive1 

  plex org concat 

    sd length 9g drive drive2 

 volume var 

  plex org concat 

    sd length 0 drive drive1 

  plex org concat 

    sd length 0 drive drive2 


I start vinum 

I do # create -f /etc/vinum.conf 


I leave vinum (CTRL+D) 


I do 

# newfs -v /dev/vinum/usr 

# newfs -v /dev/vinum/var 


# mkdir /mnt/usr 

# mkdir /mnt/var 


# mount /dev/vinum/usr /mnt/usr 

# mount /dev/vinum/var /mnt/var 


<color><param>0100,0100,0100</param># cd /
 # tar cfv usr.tar usr
 # mv usr.tar /mnt
 # tar xfvp usr.tar  

<color><param>0000,0000,0000</param># cd /
 # tar cfv var.tar var
 # mv var.tar /mnt
 # tar xfvp var.tar <color><param>0100,0100,0100</param> 


# ee /etc/fstab 

I add: 

/dev/vinum/usr		/mnt/usr 	ufs		rw		2 

/dev/vinum/var		/mnt/var	ufs		rw		2 

NOTE: I also tried /usr and /var in stead of /mnt/usr and /mnt/var 
earlier with the  same result. NOTE: please tell me which is right: 
/mnt/usr or /usr (I guess the  first) 


I do: 

# ee /etc/rc.conf 

and add: 

# start_vinum="YES" 


After this I reboot and get the problem. 

==================================== 


Thanx for your help!
