Cannot access 5big network 2

[pacco]

The binary is not mdadm but udevstart.

As you name Mijzelf script udevstart, the issue is: do you use the script or the binary available from plugout?

Sorry, my mistake...too many postings :mrgreen:
The downloaded udevstart (9-7-2013 417kb).

[pacco]

Just to be sure!

1/unplug the failed disk (5th)
2/plug the new disk
3/start fvdw-sl console and load the kernel
4/upload udevstart and mdadm
5/run udevstart at this step please...
6/ build the raid with the command

mdadm --assemble /dev/md0 /dev/sd[abce]2 --run

report output of:

cat /proc/partitions

ls -l /dev/sd[abcde]

cat /proc/partitions|busybox grep -r /dev/sd[abcde]$

So to be sure to get the right dev nodes in /dev, I'd rather that you use the Mijzelf script (patched)

Code: Select all

#!/bin/sh

while read line
do
   if [ "$line" != "" ]; then
       device=` echo $line | cut -d ' ' -f 4 `
       major=` echo $line | cut -d ' ' -f 1 `
       minor=` echo $line | cut -d ' ' -f 2 `
     
       [ -e /dev/$device ] && rm /dev/$device
       mknod -m 666 /dev/$device b $major $minor
   fi
done </proc/partitions | grep -v major

(so with -e instead of -f)

And it is Ok for me with your previous post

[Jocko]

maybe you forgot to set run permissions on the mijzelf script as the dev node are not updated and permissions are not changed (should rw-rw-rw-)

Do you do ?

Code: Select all

chmod 755 yourscriptname

Did that and saw an error in my sequence. Isn't abce but abcd.

Here is the output.

:applause It is ok now :thumbup

!	so do it only if you have this output Code: Select all root@Acrab:/ # ls -l /dev/sde brw-rw----  1 root root 8, 48 2015-05-18 17:13 /dev/sde and fdisk -l /dev/sde should list no partition Otherwise you lose your raid definitively...

note the values 8,48

Code: Select all

fdisk /dev/sde

enter: n -> 1 -> p -> 1 -> enter -> enter

then if you enter p you must see the new partition partition if it is ok enter w to save it.

enter again p you still must see the partition with type 83 and quit fdisk with q


- then format the partition

Code: Select all

mke2fs-ext3 -j -m 1 /dev/sde1

Just to confirm!!

[Jocko]

and fdisk -l /dev/sde should not list partitions

Please to note that I edited my format command (/dev/sde1 instead of /dev/sde)

[Mijzelf]

You'll have to run the script again after having created the partition. Else there will be no device node for /dev/sde1

[pacco]

and fdisk -l /dev/sde should not list partitions

Please to note that I edited my format command (/dev/sde1 instead of /dev/sde)

Again to make sure:

Code: Select all

root@fvdw-sta-kirkwood:/ # fdisk -l /dev/sde

Disk /dev/sde: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sde doesn't contain a valid partition table
