indeed there is a small error in the script :

replace the line

[ -f /dev/$device ] && rm /dev/$deviceby

Code: Select all: [ -e /dev/$device ] && rm /dev/$device

(the device node files are special files)

Note: no worry about the major alert.

Now trying to transfer data out of the box to another NAS.

See posting: http://forum.nas-central.org/viewtopic.php?f=263&t=17165&start=0

before making a backup you may try to repair your sde disk and then no need to do it.

OK, let's try that first then.
What do I need to do, reboot with the kernel and start from scratch?

Please walk me through it. Thanks!

So first with your bugged script you did not update the device nodes.

Then:
1/ update it (see my previous post).

2/ mdadm --examine /dev/sd[abcde]2 to find the real bad disk

3/ fdisk -l /dev/sde (I assume that sde is the bad disk)

4/ upload the static e2fsck (viewtopic.php?f=26&t=1412&p=9504&hilit=e2fsck+static#p9504) but the file is also corrupted you need to wait fvdw

5/ run e2fsck

by **Jocko** » Mon May 18, 2015 3:44 pm

Sorry the right command is

Code: Select all: mdadm --examine /dev/sd[abcde]2

Please to note after each boot you need to upload again mdadm, your udevstart script and run it.

There is a strange thing in your output for sda,sdb,sdc and sdd the bad disk is sde but for sde it is sdd ! :scratch

So I assume that the majority is right... post the partition table of this disk

Code: Select all: fdisk -l /dev/sde

by **pacco** » Mon May 18, 2015 3:59 pm

Code: Select all: root@fvdw-sta-kirkwood:/sbin # 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 Device Boot Start End Blocks Id System /dev/sde1 1 250 2008093+ 5 Extended /dev/sde2 251 121601 974751907+ 83 Linux /dev/sde5 1 32 256977 82 Linux swap /dev/sde6 33 33 8001 83 Linux /dev/sde7 34 34 8001 83 Linux /dev/sde8 35 140 851413+ 83 Linux /dev/sde9 141 249 875511 83 Linux /dev/sde10 250 250 8001 83 Linux

So partition table are ok

instead of using the static e2fsck tool we can try to use a busybox applet do

Code: Select all: ls /bin/fs*
