You can repeat that for the other 4 partitions, where you of course also change the names of the output files.
Then also do
Code:

cat /proc/partitions >>/mountpoint/environment
ls -l /dev/sd*2 >>/mountpoint/environment
mdadm --examine /dev/sd[abcde]2 >>/mountpoint/environment




did you also do these 3 commands Mijzelf proposed ?

Still need to copy over mdadm and do it and then it'll be done!

Re: Lacie 5Big2 Failed After Firmware Update

I did it all and got

mdadm: No md superblock detected on /dev/sdb2.
mdadm: No md superblock detected on /dev/sdc2.
The output is redirected to the file /mountpoint/environment, except these ones, because this are error messages.

The command to create a new array is:
Code: Select all
mdadm --create --assume-clean --metadata=1.0 --layout=left-symmetric --chunk=512K --level=raid5 --raid-devices=5 /dev/md0 /dev/sd[abcde]2
As far as I see this will create an array with the same characteristics as the current one. (chunksize, layout, ...)

Because the role of the partition in the array is imposed by the sequence [abcde] it's important that the device nodes are in the same order as the physical disks. So check if the minors of
Code: Select all
ls -l /dev/sd*2
match the ones in
Code: Select all
cat /proc/partitions
before going on.
