attached standalone kernel based on linux 3.9.5
Unzip the archive and put the file in the tftp folder of the fvdw-sl-console
Select it when loading the standalone kernel with fvdw-sl-console

In telnet client give this command to get and run the fvdw-sl-programs to upload mini glibc and tools

replace ip-pc by the ip of your pc running the console

chmod 755 fvdw-sl-programs.sh
/fvdw-sl-programs.sh

I did all steps above, but what should I do next?
Which option of the "Select script" menu must be selected? 4? and then

Code: Select all

Hi

At each time you reboot the nas you have to repeat all the commands when you use fvdw-sl console.

So you have to re-assemble the md4 raid5. Check if it is ok

Code: Select all

cat /proc/mdstat

and try to mount it with the regular mount command (and not the busybox applet command)

Code: Select all

mkdir /md4
/usr/sbin/mount /dev/md4 /md4

if it fails again post the output and also run dmesg to have additional information

later you can try to use also the busybox command:

Code: Select all

busybox mount -t xfs /dev/md4 /md4

cat /proc/mdstat

The output of the cat command is shown below.
So, md4 must be assembled, isn't it?
Which code you suggest to use for this assembling?

Code: Select all

root@(fvdw-kirkwood):/ # cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]

Yes you have to repeat the command to assemble it so

Code: Select all

mdadm --assemble /dev/md4 /dev/sd[abcde]2

before checking it

[fariaslcfs]

mdadm --assemble /dev/md4 /dev/sd[abcde]2

before checking it

Use --run to insist?

Code: Select all

root@(fvdw-kirkwood):/ # mdadm --assemble /dev/md4 /dev/sd[abcde]2
mdadm: /dev/md4 assembled from 4 drives - need all 5 to start it (use --run to insist).

yes add the option '--run' with the mdadm command

I do not understand why sde is missing...
So do

Code: Select all

mdadm --run /dev/md4

[Jocko]

Then about sde please to post

Code: Select all

mdadm --examine /dev/sde2
