Solved How to change from zfs to ufs on Solaris 10?

July 11, 2016 at 02:46:08
Specs: Solaris 10
I have a V245 that was running a zfs system and a set of cloned ufs drives that contain a complex test system that I which to run on the V245. However a naive removal of the zfs drives and replacement with the ufs drives does not allow me to boot past the ok prompt.

The error I get is:

"Can't open boot_archive
The file just loaded does not appear to be executable."

I know the cloned drives are good as I can boot from them on the system they were cloned from (a T5120).

I assume that this is something to do with a configuration setting that means that the system is looking for a zfs filesystem? But I am not sure if that is correct, or how to fix it.

Any help would be appreciated.

The problem may be that the processor in the V245 is an older generation than that in the T5120. Although the T2 is backward compatible with IIIi I'm not sure that it works the other way round.

Another point to consider is whether the UFS drives formed a RAID array.

The ufs drives definately did not form a raid and I am only only running Solaris 10 - so compatibility shouldn't (he says hopefully) be an issue should it?

✔ Best Answer
As far as I know, the server can't remember what filesystem was on the old disks. It has to be some sort of hardware incompatibility between the hardware and the OS installed on those new disks. It may be the disk controller rather than the CPU, but I can't see that it just a question of a different filesystem.

Hmm any ideas on how to find out for sure / proceed? or is it a case of give up?
Fundamentally I cannot see why it wouldn't work - but then again it doesn't so...

I'm not entirely sure with Solaris but certainly Windows only installs those drivers that it needs. So if you move a Windows disk from one computer to another with different hardware the chances are that it won't boot.I can imagine that it might be the same with Solaris.

Is it not possible to just install the test system on the existing ZFS installation?

Unfortunately it is not possible to install the test system on the zfs installation :(
At least not as far as I know.

Looks like this is going to stay unresolved. *Sigh*
