Debian Stretch on Armada-370 Buffalo Devices (LS2XX, LS4XX, TS1XXX)

Is your power switch in the "ON" position when you make a shutdown?

yes. I haven't moved it in my testing so far

The new nas is running very good.
But i have the same error like all Linkstations.
Only Terastations can show the correct value for "Size on disk"

My try to analyse the difference betrwean the correct working TS1200 and the buggy LS420:

Can you help me to find the error.

I read the whole thread and have some thoughts. I don't do much with windows so I could be missing some of it.

at one point you notice the difference between the output of df -h and the expected sizes (MB vs MiB). Modern versions of df have a "-H" (uppercase) which may give you what you want.

you mentioned at another point showing 5% usage on an empty filesystem (i think). This seemed like it might be due to "reserved blocks" in the filesystem. you can adjust the reserved blocks of a filesystem with tune2fs -m. I usually set it to 0 for large data disks and keep the default of 5% for my /

You also mention the large difference between file size and size on disk and how it's different between the terastation and linkstation. This is probably due to the inode size. If you plan to store millions of 1k files like your example you may want to move to a smaller inode size to better use the disk space. This will cause larger files to use more inodes which could be a problem if you then run out of inodes

Let me know if there were other scenarios that I missed

thank you.
I will analyse the xfs formatted disk in a TS and LS

it is very simple

add the entry

allocation roundup size = 0

in the [global] section from the /etc/samba/smb.conf

and restart the service

/etc/init.d/smbd restart

short command for putty:

sed -i '/\[global\]/a allocation roundup size = 4096' /etc/samba/smb.conf ; /etc/init.d/smbd restart

Now the LS with debian can show the correct values.
rounding is dissabled.

by the way
win7 is lying
it displays the same value for data size and size on disk
this method is very fast but wrong with files smaller than 4kB

my example with 600000 files takes 6min on Win10 and 11 sec on Win7

I corrected the issues with my ls400 restart script (see attached). It now:

properly handles shutdown/restart/halt for the ls410d/ls420d/ls421d/ls441d/ts1200d by simply putting the script in /lib/systemd/system-shutdown/ and setting it as executable by root. It no longer introduces any long delays and should work reliably with most network/system configurations.

I'll be adding it to the repository/installer images soon.

Thank you.

I'm working on creating a script to automatically adjust the fan speed on devices that use the microcontroller to control the fan, I think you said you were putting something similar together for the other devices. If so, what logic are you using to map drive temperature to fan speeds?

over 42°C -> full
from 42°C to 35°C -> fast
under 35°C -> slow

Hello. Will this script work on Netgear Stora with Debian installed from Bodhi

No, the scripts main purpose is to send instructions to the microcontroller built into the board on some buffalo devices. It wouldn’t work for other devices.

1000001101000,

I've updated the Wiki to include this thread for Buffalo NAS (I had a senior moment and forgot to do this long ago :)

And perhaps the 1st post title should be "Debian on Armada and Kirkwood Buffalo Linkstation and Terastation". Thanks!
