attempt to access beyond end of device

I've been searching for this error and i found this link.

Maybe this the case? What do you think?

[fvdw]

to be honest I don't know if that is our problem

are you still using the 3.9.5 kernel of 16-0 firmware for 5big1 ?

And did you try the newer kernel (3.14.2) + modules as Jocko has send earlier ?

[samrise]

root@nas:/ # uname -a
Linux nas.local 3.9.5 #25 Thu Feb 27 22:22:32 GMT+1 2014 armv5tel unknown unknown GNU/Linux

I did a clean install with new fvdw console.

Are you refering to this post? If so, i tought it was better to wait for you.

[fvdw]

also the problem could be that the device mapper isn't loaded
what does this command tell you (it could be that you meed to reboot because the mke2fs command has flooded the dmesg buffer and so info is lost from boot

Code: Select all

dmesg | grep mapper

also

Code: Select all

lsmod

should show if the device mapper is loaded
