"Invalid partition" after movig to ESX

C

ccc

Hi

I've moved FreeBSD 8.2 to ESX4.1 and now I'm getting this error:
Code: 
Invalid partition
No /boot/loader
How to solve this?
 
Most likely just hardcoded device entries in /etc/fstab. Moving a disk from one system to another, or even to a different controller port, can give a different device number. So entries in fstab that were pointing to ad0 should now be referring to ad1.

Is the error in post #1 the only thing shown on the screen, or is there more before it?
 
Did you physically move the disk from one machine to the other? Or did you make a duplicate of the disk?
 
Was the disk setup on a MBR or GPT scheme?

Did you install a boot loader?

Does the new machine have UEFI enabled?
 
I've done an Acronis image of a physical FreeBSD 8.2 and restored this image on ESX4.1, but the VM won't boot and I get this error above.

I booted the VM using mfsBSD and here is the fdisk output:

The following commands are supported (in upper or lower case):

T = Change Type       U = Undo All Changes     W = Write Changes  Q = Finish


Use F1 or ? to get more help, arrow keys to select.
I've mounted the root partition and changed /etc/fstab:
Code: 
# cat fstab
# Device                Mountpoint      FStype  Options         Dump    Pass#
/dev/da0s1              none            swap    sw              0       0

/dev/da0s3              /tmp            ufs     rw              2       2
/dev/da0s4              /var            ufs     rw              2       2

linproc                 /compat/linux/proc/  linprocfs  rw      0       0
but it still won't boot.

Please do not use sysinstall(8) or fdisk(8) any more. The output of gpart show would be helpful.

That's a strange and complicated setup. MBR with bsdlabel(8) subpartitioning, but only one partition on each slice. And the first slice has nothing on it. Did you mean to use 24 GB for swap? Why is slice 4 set active?

I strongly suggest installing a less complicated setup on the target machine. See Disk Setup On FreeBSD for instructions on that, or just use a standard FreeBSD install CD. Back up the original computer to files (see Backup Options For FreeBSD). Boot the target computer with mfsBSD, mount each filesystem, and restore over it.

Swap is only 2 GB. I've changed in /etc/fstab:
Code: 
/dev/da0s2              none            swap    sw              0       0
/dev/da0s1              /               ufs     rw              1       1
/dev/da0s3              /tmp            ufs     rw              2       2
/dev/da0s4              /var            ufs     rw              2       2
/dev/acd0               /cdrom          cd9660  ro,noauto       0       0
linproc                 /compat/linux/proc/  linprocfs  rw      0       0

BTW how to set /dev/da0s1 (root) as active partition using mfsBSD?
 
That will still not work, because you have bsdlabel(8) subpartitions. They are only making it more complicated, requiring the links to be /dev/da0s3a for /tmp, for example.

But you also have no /usr filesystem at all.

gpart(8) can set partitions active. Please see that manual page or the disk setup article for examples.
 
Using mfsBSD, I've done the following:
Code: 
root@mfsbsd:/ # gpart bootcode -b /boot/mbr da0
bootcode written to da0root@mfsbsd:/ #  gpart set -a active -i 1 da0
active set on da0s1
root@mfsbsd:/ # gpart show

Now I can boot my FreeBSD without any errors and everything works well!
