You probably forgot to run swapoff to remove all swaps, and then run swapon for the new swapfile.

The uboot thread only shows 2015.10 as the latest version. Seems like it also supports the uEnv.txt

I'm on 2013.10 I believe. Is there a command I can run to check the current version of uBoot on Wheezy? If I get on the 2015 version that should work right?

That's the wrong u-boot! It is for the Pogo V3 Oxnas.

The Kirkwood Pogo E02 u-boot is here:

Hey Bodhi, yeah, I should have mentioned I'm trying to do this on a Pogo Pro based on feedback from Alamaz. Sorry for the confusion. Obviously a pretty significant noob here :)

It can be used on any model and I suggest to use swap disk.

I see :) I've assumed you are doing this on Pogo E02 because of the thread title.

Yes, uboot.2015.10-tld-1 should work.

To check u-boot version without serial console or netconsole.

grep -a --null-data U-Boot /dev/mtd0ro

Afer executing the above comand, you might find a lof of errors in dmesg as a side effect of this. Don't panic! it is normal.

Thanks. I have 2013. Do I need to upgrade to enable swap or can I do it manually and test plex first before going through the process of updating uboot?

This is a really old set of envs from 2013! You should really use the new default envs. But that's another day.

In Debian, set the zswap option to the bootarg directly:

fw_setenv usb_set_bootargs 'setenv bootargs console=ttyS0,115200 root=/dev/sda1 rootdelay=10 zswap.enabled=1'

And reboot.

And after log in again look at dmesg to confirm that zswap is running. And check current swap:

cat /proc/cmdline
dmesg | grep -i zswap
free

I was able to do the fw_setenv command and see it was entered by running fw_printenv. However now when I reboot I can no longer get SSH access. I thought it was my other connected USB devices causing issues (sound card, 512MB flash for swap, mircroUSB charger cable) but unplugging those and rebooting still gets me nowhere. I guess it's back to serial connection :( I'd love to know how to get this system to be a little more stable.

EDIT: I guess I didn't wait long enough. It finally came back online.

root@DebianPlugPro:~# cat /proc/cmdline

Now should I set swapiness? Starting at 10 and bumping up to 60 if need be? Where can I set that value? And as always. thanks so much!

You are running a kernel that does not have zswap. You should see:

Which kernel is this?

Linux DebianPlugPro 3.18.5-oxnas-tld-1 #2 SMP PREEMPT Thu Feb 12 11:17:40 PST 20
15 armv6l GNU/Linux

I was able to start the Plex server with my current setup (swap enabled) and leave it on overnight, and access and play the 1 album I loaded in to the music library. But after adding another library, the scanning process seemed to kill the service almost immediately.

I'd be glad to get everything up to date, but I'm curious if Zswap is going to help with the performance on the PogoPro in this case.

I also am fairly confident there will be some gaps in my understanding of how to get everything updated (Kernel, Rootfs, uBoot) so I'll warn ahead of time that many a question will likely be asked.

Thanks again

This kernel does not have zswap. So you should install the latest kernel.

It might help. Since zswap compresses the swapped out memory in RAM so it swaps much more infrequently. However, when it crashes like that, then you would need more swap space. Perhaps 384M is not enough. I would experiment with a larger USB drive to see how much Plex needs.

In any case, zswap is going to help a lot when the swap space is on flash drive. I did the experiment myself on these 128MB RAM plugs with xfce desktop running, constantly out of RAM. But I don't use Plex so don't know the technicals, i.e. how it would help.

I'd would be glad to answer any kernel installation and booting understanding/problems! The key to get your questions answered faster, without a lot of exchanges, is to keep a log of what you do, and post it along with the questions.

I've decided to try Plex on my new PogoPro with the latest uBoot, Kernel, and rootfs. This is the result after a reboot. cat /proc/cmdline doesn't mention zswap. It is however in the demsg output.

root@debian:~# cat /proc/cmdline
console=ttyS0,115200 root=LABEL=rootfs rootdelay=10 mtdparts=41000000.nand:14m(b                   oot),-(data)
root@debian:~# cat /uEnv.txt
custom_params=zswap.enabled=1

dmesg output

zswap: loaded using pool lzo/zbud

So good to go on zswap?

cdlenfert

Yes. It is activated. To verify, simply rename uEnv.txt to something else to deactivate it.

Now you can use vmstat to monitor the swap to see if it helps.

vmstat 5 300

A lot of swapping will occur when you run something as memory intensivve as Plex. With zswap enabled, the swapping should be a lot less infrequent. And use a 4GB swap file to see if if handle Plex OK. If 4GB is not enough, use 8GB swap fle.

Still crashing on my after initiating a scan. Here is the output of vmstat after starting Plex. The second line was the point that it was up and running.

I've dedicated a 4GB thumb drive as a SWAP partition. I can try with 8GB, but I expected there to be a difference when using 4GB swap vs 384mb and it's choking at the exact same point I think. Anyone have this working and care to share their OS, Swap size, etc?

cdlenfert,

Do you have the dmesg log show how it crashed?

Something is definitely wrong, I'm running sickrage, plex, couchpotato, samba, transmission and a lot of other services on E02 and it never crashed. I don't use usb memory because it's slow. I prefer running OS on the same hard drive as my media file server, makes it much faster for everything.

What size is your swap? I'll reboot and run again and see when the crash occurs

My swap size is 256mb

Just a guess, you could have bad/corrupted file in media folder. Plex might crash because of that .

Not a lot of the main memory is being used (46mb), and very little of the swap (11mb), however it shows Plex as using 193mb. This is on the PogoPlug Pro with the smaller swap file.

If you guys can give a better command to monitor the death of Plex, please let me know. I can pretty easily repeat the killing by playing a song or running a library scan.

Thanks

Disable Plex DLNA Server if you don't use it.

Also do the following

nano /etc/default/plexmediaserver

# default script for Plex Media Server

# the number of plugins that can run at the same time
PLEX_MEDIA_SERVER_MAX_PLUGIN_PROCS=1

# ulimit -s $PLEX_MEDIA_SERVER_MAX_STACK_SIZE
PLEX_MEDIA_SERVER_MAX_STACK_SIZE=3000

# where the mediaserver should store the transcodes
PLEX_MEDIA_SERVER_TMPDIR=/tmp

# uncomment to set it to something else
# PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR="${HOME}/Library/Application\ Support"

# the user that PMS should run as, defaults to 'plex'
# note that if you change this you might need to move
# the Application Support directory to not lose your
# media library
PLEX_MEDIA_SERVER_USER=root

Disabled the DLNA server, but that didn't reduce the ram usage it showed for Plex. It actually was higher at 213mb.

Editing the default script file the only change was to change:

PLEX_MEDIA_SERVER_MAX_PLUGIN_PROCS=1

Which I did. I had it =2 before.

Added a library (single folder with 2 albums of appx 128kbps mp3 files). The scan crashed the plex server.

Running htop after the crash I still see this

Plex requires the correct locale. I'd guess it might cause a problem.

locale -a

C
C.UTF-8
en_US.utf8  ----> IF MISSING then
POSIX

apt-get install locales
dpkg-reconfigure locales

If nothing works reinstall debian from scratch which can be done in less than 30 min

root@DebianPlugPro:~# locale -a
C
C.UTF-8
POSIX

You must add en_US.utf8

Try this as well

apt-get install libc6

I wasnt able to use the configuration tool to generate the locale, so I edited the local.gen file manually to uncomment the en_US.utf8 line:

root@DebianPlugPro:~# nano /etc/locale.gen
root@DebianPlugPro:~# locale-gen
Generating locales (this might take a while)...
  en_US.UTF-8... done
Generation complete.

My order is different if that matters?

root@DebianPlugPro:~# locale -a
C
C.UTF-8
POSIX
en_US.utf8

And the following seemed to go fine:

However, when I run Plex it seems to crash even quicker than before, basically with no interaction.
