Hey I'm really sorry to keep bothering you. I upgraded since I've first written this post to FreeNAS 11. Haven't had any problems with the old linux jails booting and running.
With the iohyve linux install this is what I found:
Code:
[kevdog@freenas /dev/zvol/tank/iohyve/ubuntu]$ sudo fdisk disk0
Password:
******* Working on device disk0 *******
parameters extracted from in-core disklabel are:
cylinders=3916 heads=255 sectors/track=63 (16065 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=3916 heads=255 sectors/track=63 (16065 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 131 (0x83),(Linux native)
start 2048, size 58718208 (28671 Meg), flag 80 (active)
beg: cyl 0/ head 32/ sector 33;
end: cyl 1023/ head 254/ sector 63
The data for partition 2 is:
sysid 5 (0x05),(Extended DOS)
start 58722302, size 4190210 (2046 Meg), flag 0
beg: cyl 1023/ head 254/ sector 63;
end: cyl 1023/ head 254/ sector 63
The data for partition 3 is:
<UNUSED>
The data for partition 4 is:
<UNUSED>
I believe this information to be correct.
Partition 1 - Is the entire system
Partion 2 - Is the swap partition
As an experiment however I went ahead and created a new zvol and actually created a new Ubuntu jail with the FreeNAS gui. (Side note -- much easier than the old Iohyve way of doing things with the new ability to use VNC viewer).
Anyway during the installation I created three partitions - vda1, vda2, vda3.
vda1 -> /boot/efi
vda2 -> /
vda3 -> swap
My problem is when actually examining the zvol created for this installation. It shows just one partition
Code:
[kevdog@freenas /dev/zvol/tank/iohyve/Ubuntu-FreeNAS]$ sudo fdisk disk0

I'm very confused. In fact it doesn't make a lot of sense to me. I would have thought I would be shown in this instance three partitions. I was hoping to take my old root partition and dd to the new root partition, however that doesn't seem possible.
