Firmware made my disk slow?

Firmware made my disk slow?

Postby Walburga » Sat Dec 10, 2016 3:37 pm

Dear,

I installed the fvdw-sl firmware version 16-1 on my lacie-cloudbox.
But I have the feeling that I am loosing connection now and than?

If upload a file on the drive it has a maximum upload speed of 11MB, and from time to time it goes to 0 (it looks like it looses the connection).

Yesterday I tried to watch a movie from my HDD (streaming via a Raspberry 2 OSMC) and from time to time the movie froze and OSMC shut it down. I never had this with the lacie firmware.
Maybe I did something wrong or did I oversee something in the installation?

P.S. This aside, thanks for creating this firmware! I mean lacie doesn't give any option after a system failure and you do. So thanks for this! And also, thanks for making it rather easy to install it on a disk, the guidelines are very easy to follow!

Hi, an upload speed of 11 MB/s is rather low unless it are many small files you are uploading. If it is a big file you should be able to get at least 20 MB/s.
Download speed will be higher and should be more then enough to stream a movie.
There is one thing that can slow down transfer that is if you have multiple task runnung on your cloudbox or more then 1 user is active on same time. Also twonky mediaserver can slow down performance when it is building its database and you have a large number of media files on your nas. But after building the database this should be no longer hamper performance.
It seems something is keeping your nas busy.

You could connect via ssh (putty) and give command "top" at the linux command line to see what keeps your nas busy. It will show cpu and memory use per active application

The 'Top' command didn't reveal anything.

The cloudbox is doing nothing, so it has to be the network. I'm going to analyse it more...

Thanks for the tip though!

It is strange you have two root child processes 'smbd'

You should have only one root child process and as many user processes as opened samba accesses :scratch

So try this
Code: Select all
killall smbd
/usr/sbin/smbd -D -l /var/log/samba

I ran your command, now there is only 1 left. But if I stream a movie, it's still rather slow.

But I must say, the general reaction of the NAS seems better (browsing through folders & accessing the Web Interface)

Are there more things I could check? Or test?

What is the speed setting of your ethernet interface and do we see many collision errors on your lan.
Some info we can get from this command
Code: Select all
ifconfig eth0

and this command
Code: Select all
ethtool eth0


Ps Streaming is usually less then 1MB/s unless you stream uncompressed hd files. The network interface is normally no problem as it is far below the maximum.

Do you use a wireless connection between your TV and your LAN when streaming, or a wireless connection when uploading a file from your pc. The symptons you describe are typical for a wireless connection suffering from interference
