[NEW DSM 5.1-5004 AVAILABLE !!]

Any tried the new upgrades yet?

 

5.1-5004.2

 

 

It's an upgrade, so as long as there isn't a way to get the V5.1-5004 up and running it won't be possible to install the U2...

[NEW DSM 5.1-5004 AVAILABLE !!]

So, I think it safe to say DSM 5.1 uses superblock 1.2 for the data array.

 

Correct, but as DSM 5.0-4528 U2 also uses superblock 1.2 it can't be the cause of problem which we are having with DSM 5.1.

 

I installed 5.1 on a simple bare metal test system and I see the following:
