Why not using Ext3/Ext4 for this drive?

Swap is in i-data - internal drive

The only thing that is NTFS, is an external 2GB USB drive.

Internal harddrives were empy and without partitions, when inserted into NSA. Partitions are, what NSA makes them as standard.

Ah, I see. You are back running stock kernel! I've misunderstood your post. I did not bother to look at stock kernel too closely, so I won't be of much help there. However, from previous log, you're running out of memory. And your free -a command output confirmed that.

Strange that swap is not even touched, though.
Have a feeling that this might be related to drive issues (non pageable ram in ntfs module?).

What are values of:
cat /proc/sys/vm/swappiness
cat /proc/swaps
cat /proc/meminfo
swapon -s
cat /proc/sys/vm/vfs_cache_pressure

Did you install any 3rd party modules/plugins?

Bye!

only thing i have done since reset and format, is to install Transmission and deactivated the mediaserver module.

If you like, i can PM you my Telnet login infos... then you maby have a chance to see more

user mode processes can definitely be swapped out.
You should try allocate fake ram and see if swap kicks in. Don't know if this is doable with stock kernel (i use tmpfs for this).

Also, errors in drives can definitely put a system on its knees, expecially for foreign fs like NTFS (where drivers are not so well written for Linux).
How about checking the NTFS drive from within Windows (chkdsk /R) ?
Or, if you don't mind, reformat in ext4.
Lastly, since this is a USB drive, make sure it has enough power.

Have removed the external 2GB harddrive. Will try again without it.

EDIT: Seems to be working now. Reformated ALL drives and made a full reset of NAS again ( with pressing the reset button for 2 beeps )
Have been working since yesterday.

Sorry for this dupe, i posted this on the main kernel thread and yet discovered this one and moved it. My appologize

Running
Zyxel 325v2
- with 3.16.0-kirkwood-tld-1
- bootinf from USB

Thanks for your awesome job already, i really loved the progress and work!

1. Iam currently eager trying to get my Zyxel suspending, but pm-tools do not work, since /sys/power is missing completely. Is there no suspend /hibernate support in the kernel right now?

2. The hardware "off/suspend" button does not work at all. Is this a now issue / not supported yet?

Is this the right way to give feedback or did i missuse those comments? Thank you!

@butty:
I had my own troubles getting tty run on the zyxel, here is how it worked out
- you dont need to connect the 3.3V and if you do, ensure its 3.3V .. a lot of adpaters are broken and proved 5V
- if you get a black scren, ensure you did not swap TX/RX and just swap them in case (you cant damage anything y that)
- just connect grnd/tx/rx and you are good to go

tty question myself:
- anybody has a working keyboard on the tty? Iam using http://www.amazon.de/USB2-0-Konverter-seriell-CP2102-PAUB022/dp/B004AIAN5K/ref=cm_cr_pr_product_top#productDetails ATM but keyboard does not work

Now that I got sometime to play with the NSA325, I'm seeing this in dmesg also. Have you figured out this problem?

bodhi's corner (buy bodhi a beer)

Today i did some perfomance tests with AFP/SMB/SCP on a 1GBit connection, writing a 500MB file (single file), on 7200pm older seagate baracuda.
1. iam using rsync with --progress on an i7 desktop hackintosh with an 1GBit wired ethernet directly plugged into the nas (not routing)

- while scp is saturated with 10mb/s due to 100% cpu load - very suprising load kinda

- with ext2 , i get 38mb/s (AFP)
- with ext4, i get 30mb/s (AFP)
- with xfs, i get 38mb/s (AFP)

- with ext4, mdadm raid1(1drive missing), i get 32mb/s (AFP)
- with xfs, mdadm raid1(1drive missing), i get 37mb/s (AFP)

- samba4 is about 7mb/s slower then AFP

The slowness, yet again, of ext4 is astonishing. Also on our i7 servers running proxmox, using ext4 for the raid (esp when mdadm) kills any performance. With a megasys raid its horrible with ext4, ext3/ext4 and xfs are ok.

this is for right now the half of the measure values on smartbuilders and iam suprised. A lot of people already complained about the performance, is this kernel or rather debian related?

With the stock ( not FFP ) uboot i get, same drive as before
- JBOD, samba (42mb/s)
- JBOD, FTP (60mb/s)

Since iam using a mac i guess the 4mb/s on samba are rather smb related, due to the horrible samba implementation in OSX. I could not also make FTP tests on the debian, i cant make AFP tests on the stock boot since its harder to setup there.

Overall it looks like the performance is nearly twice as good on the stock kernal eventhough i have a lot more stuff running. On the debian boot i dont have anything except AFP/Samba4. No httpd, no nothing else

Were could those performance issues come from?

Could be the Ext4 driver in the new kernel.

-bodhi
===========================
Forum Wiki
bodhi's corner (buy bodhi a beer)

Well, since the performance is "bad" with ext2 and xfs, it cant be just the ext4 driver. It must be something else. It seems like the CPU load is very high during transfers, somehow

You could check network and drive throughput separetly:
1. Network throughput: with netio on NAS and PC/Mac -> TCP/UDP
2. Drive throughput: with dd

write:dd if=/dev/zero of=/media/usb0/test.tmp bs=500K count=1024
read:      dd if=/media/usb0/test.tmp of=/dev/null bs=500K count=1024
copy:   dd if=/media/usb0/test.tmp of=/media/usb1/test.tmp bs=500K count=1024

With these data you can see if there are already differences in ext4 drive access and/or differences in network speed due to different kernels.

CIFS reading speed from my NSA325-v2 from single Ext4-JBOD drive with original FW: up to 86 MB/s
CIFS writing speed to my NSA325-v2 to single Ext4-JBOD drive with original FW: up to 63 MB/s

K, a few comments in regards to all of that last 4 posts:

Disk array configuration: note that the stock tests are on JBOD, not RAID'ed in any way.

In my test, my config:
PC: Arch Linux, FX-8120, ASUS mobo, Seagate Barracuda 11 7200RPM (single)
NSA-325v1: Arch Linux ARM, Seagate Barracuda 11 7200RPM (single)
Network: GbE via NetGear GS108T, no other high load.

The HDD are matching batch, same week of production, formatted as a single large ext4.

All file transfers handled via bash, after a mount @ cmdline.

I completely disabled the sensor after WarHeadsSE answered this way:
http://forum.doozan.com/read.php?2,14351,16068#msg-16068

I can see that the fan *is* working autonomously and does not require any usermode daemon.

Nope, exactly.
I can't remember if stock firmware has a sensor for that?
Would be interesting to have one... but I can nonetheless witness no failure with 40°C outside this summer (1 WD Green hard disk), using custom kernel.

BTW, more important than this, is there a usable U-boot version for this device yet?

@WarheadsSE,

Do you have any plan to implement the NSA325 MCU status readout in the kernel? perhaps a module?

-bodhi

bodhi's corner (buy bodhi a beer)

I hadn't intended, no. Not that it isn't possible, but I've got no need for it myself.

Me neither. I just thought about it because I came across the mcc module in stock kernel while browsing around. This module reads the temperature (pull down and pull up those 3 GPIO pins).

@davidedg,
Have you tried the test U-Boot? I'm running NAND version and it has been very stable.

@WarheadsSE
BTW, I have tried to see if I can chainload stock U-Boot from the new U-Boot. I could not get it to load, it just hang. It seems like stock U-boot is old, but not old enough to do this successfully. But there is a path to stock after you've installed new U-Boot: we can UART boot my stock U-Boot build image.

As I understood from your reply to sigma, new Uboot has different location for its env and won't touch the stock one.
But, since it's new uboot, I may as well create a new more powerful environment (scripting), correct?

Also, did you include EFI partition support?
