Yes, I made a confusion between your topic and samrise's one

Indeed you used msdos partitions tables and at least that proves that there is no issue with the kernel version to build raid on this partitions table type (so samrise's issue is amazing)

if on your sda disk you have still this partitions tables (viewtopic.php?f=30&t=2168&start=10#p18188), maybe there is an issue if sda is an AF disk.
Indeed the end block of partition 4 and 8 is wrong and if you have an AF disk you have a misalignment issue between logical sectors (512) and physical sectors (4096)
A misalignment decreases drastically the I/O speeds.
Also your raid uses as metadata version 0.90 (default version) and then the superblock is written into a 64K aligned block that starts at least 64K and less than 128K from the end of the device. So on the misaligned block !

Code: Select all: Disk /dev/sda: 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/sda1 9 72 514080 83 Linux /dev/sda2 73 136 514080 83 Linux /dev/sda3 137 200 514080 82 Linux swap /dev/sda4 201 121601 975153532+ 5 Extended /dev/sda5 209 312 835380 83 Linux /dev/sda6 321 328 64260 83 Linux /dev/sda7 337 400 514080 83 Linux /dev/sda8 409 121601 973482772+ 83 Linux

So the size of partition 4 and 8 is not divisible by 8 :
(121601-201+1)/8=121400,125
(121601-409+1)/8=121192,125

I don't known where you got this partition table
Please to note that the end block value is right with 121600 for the other disks.

First step, can you confirm me that you have an AF disk?

The partition table for sda was made by the installer automatically... i never made any changes.

Since i noticed that the end block on sda was 121601 after many tries with 121600 i tried with 121601 on the other disks too...but if the correct value is 121600 i will change it.

My disks now are all Seagate 1TB ST1000DM003 and they are AF disks

Indeed it seems to have an issue with the install script if you use a msdos table.

With gpt tool, there is a mechanism to auto-align logical sectors with physical sectors but not with fdisk

So currently the script set as end block the last available sector for partition 4 and 8.

!	You need to use the last fvdw-sl console version 5.5

To fix it and keep your settings do :
- Before using fvdw-sl console, open a Putty window and backup sda5

Code: Select all: dd if=/dev/sda5 of=/share/1100/sda5.img

- Stop your nas, and use fvdw-sl console to load a standalone kernel (UIMAGE-26394-5BIG1-42standalone) and get a telnet access.

- in the telnet window, assemble your raid

Code: Select all: mkdir /md mdadm --assemble /dev/md0 /dev/sdb8 /dev/sdc8 /dev/sdd8 /dev/sde8

- mount md0

Code: Select all: mount /dev/md0 /md

- check if you see the file sda5.img

Code: Select all: ls -l /md

- if yes, then we can delete partition 4, 5, 6, 7 and 8:

Code: Select all: fdisk /dev/sda

- in the fdisk environment do:
* the sequence

Code: Select all: d(enter)4(enter)

* check if the partitions are deleted

Code: Select all: p(enter)

* if yes, save the changes

Code: Select all: w(enter)

-create again the partitions, still with fdisk on sda disk do:
* the sequence

Code: Select all: n(enter)e(enter)201(enter)121600(enter)(enter)n(enter)209(enter)312(enter)(enter)n(enter)321(enter)328(enter)(enter)n(enter)337(enter)400(enter)(enter)n(enter)409(enter)121600(enter)(enter)

(note the input 'e' for partition 4)
*check if the new table is ok

Code: Select all: p(enter)

* if yes, save the changes

Code: Select all: w(enter)

- restore sda5 content

Code: Select all: dd if=/md/sda5.img of=/dev/sda5

- restore the kernel

Code: Select all: busybox tftp -r 5big1/UIMAGE-395-5BIG1-25 -l /md/kernel.img -g ipPC dd if=/md/kernel.img of=/dev/sda6

(ipPc is the IP of your PC)
- restore firmware image on sda7

Code: Select all: busybox tftp -r firmware/xfvdw-sl-16-0-nwsp2-11apr2015.img -l /md/firmware.img -g ipPC dd if=/md/firmware.img of=/dev/sda7

(ipPC is the IP of your PC)
- format sda8

Code: Select all: mke2fs-ext3 -j -m 1 /dev/sda8

Reboot the NAS and install again the firmware image for 5big1.

After rebooting, you need to edit again the insert-modules file to load raid (bug in version 16.0 with 5big1) http://plugout.net/viewtopic.php?f=30&t=2168#p18177
and then do a last reboot...

So many jobs and I am not sure that this block issue may explain your slow synchronize speed... :whistle

when i loaded the standalone kernel using fvdw-sl console sda and sde was inverted

Code: Select all: root@(none):/ # fdisk /dev/sde The number of cylinders for this disk is set to 121601. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): p 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 9 72 514080 83 Linux /dev/sde2 73 136 514080 83 Linux /dev/sde3 137 200 514080 82 Linux swap /dev/sde4 201 121601 975153532+ 5 Extended /dev/sde5 209 312 835380 83 Linux /dev/sde6 321 328 64260 83 Linux /dev/sde7 337 400 514080 83 Linux /dev/sde8 409 121601 973482772+ 83 Linux

Ok, it is strange as this issue should be solved with 5.5 but other members has already reported this issue. :scratch (not sure but as you use an old kernel version, maybe fvdw has not yet rebuilt the standalone version for 5big1 ???)

You should have a script to restore the device node : try to run udevstart (at each boot you would run it) and post here the content of

Code: Select all: cat /proc/partitions

Note: you must update the dev nodes to be able to assemble your current raid

Other way to assemble a raid if the dev nodes are not updated:
-get the uuid of the raid

Code: Select all: mdadm --examine /dev/sdb8

(we are sure that sdb8 is in the raid all case
then in the output you should have the line 'Array UUID : 17158363:82face30:990b8e54:1abf48ea'

then assemble the raid with this command

Code: Select all: mdadm --assemble --uuid uuid_array_value /dev/md0

Actually, before loading the standalone console i have reinstalled again the firmware because the nas didn't boot anymore.
Do i need to rebuild the 4 disks raid5 before to run your assemble command?

by **Jocko** » Tue Sep 22, 2015 9:27 am

Maybe a better way.

I go to send you a patched install script where the cynlinder end will be in any case 121600.

So wait a small time.

by **Jocko** » Tue Sep 22, 2015 9:41 am

As you have installed again the firmware, there is no data to be saved.

- stop the NAS
- remove sd[bcde] disk
- unzip the attached file in tftp folder (you get a new file fvdw-sl-installer1.sh)
- use fvdw-sl console to load a standalone kernel (UIMAGE-26394-5BIG1-42standalone) and get a telnet access
- load this script

Code: Select all: busybox tftp -r fvdw-sl-installer1.sh -l fvdw-sl-installer1.sh -g ipPC

(ipPC ip of your PC)
- set run permissions

Code: Select all: chmod 755 fvdw-sl-installer1.sh

- run the script to format the disk

Code: Select all: ./fvdw-sl-installer1.sh

Note: fvdw-sl-installer1.sh must be used only with your disk as in all case it sets as end cylinder 121600 for the partitions 4 & 8.
