Error creating Raid 5

[fvdw]

To find out what is wrong with 3.18.2 we are going to use the u-boot console to load the kernel and try to use netconsole to see what goes wrong with the kernel. I will post instructions later this evening

[fvdw]

how load the new kernel using u-boot console

put the 3.18.21 kernel in the tftp directory of the fvdw-sl console
Switch off the nas, start fvdw-sl console and choose as action, start tftp server after choose as action u-boot console

Start the nas and wait until u-boot console interrupts the boot and the marvell>> prompt appears

in the u-boot console windwo give these commands

Code: Select all

setenv bootargs console=ttyS0,115200 netconsole=6666@${ipaddr}/,6666@${serverip}/ root=/dev/sda7


use the commands exactly as they are given so do not replace the parameters ipaddr and serverip leave them as they are in this command
PS the u-boot console window has a paste option (right click on title bar)
check if now bootargs is set to this string

Code: Select all

printenv bootargs

proceed

Code: Select all

ide reset
tftpboot 0x400000 UIMAGE-31821-5BIG1-3
bootm


If the kernel loads it should show you after mention starting kernel detailed output of kernel laoding in the u-boot console window. If the kernel fails before netconsole is activated in the kernel then there will be no output

Hi,
I have to do this before or after restoring the previous kernel?

[Jocko]

Yes , you can restore the kernel version (at least you will have a functional nas with a standard booting) before following fvdw's instructions to see what happens when bootloader uses version 3.18.21

[b1gnas]

i'm at this point, and now?

Hi b1gnas,

You need to do an additional command

Code: Select all

bootm

[b1gnas]

it's blocked here...

Code: Select all

Marvell>>  bootm
 bootm

Maybe the kernel size is too big.

So you need to wait fvdw now and you can restart the nas

[fvdw]

looking to were it hangs (before actual unpacking and starting the kernel) this could be the problem that it overwrites u-boot, although the size in bytes is smaller then 2MB which should be ok :scratch

Anyhow need to find a way to make it smaller and then try again

[fvdw]

attached a new kernel and a set of modules belonging to this kernel for testing

ps you need to adapt the command Jocko posted to unpack de kernel and the modules archive as the names of the files are adapted (what to change speaks for it self I think)

Hope you can find some time to test it
