Hi khelm,
are you successfully using the board?
I'm also interested in using it, since it offers everything you need in a small package.

Somehow it worked out itself this night.
When I checked the status of my OMV this morning the size has changed.
It's now 10.74TiB. I guess the the progress started and I got the error message because I tried it again.
I think it is a bit odd that you don't get any status information of the size increasing process....Another thing I noticed:
At the raid management screen it tells me that the array size is 10.92TiB.
At the file system screen it tells me it's 10.74TiB now.
Is this size difference due to filesystem and block size (I'm using ext4)?Thanks for the help...

Hi there,
I upgraded my raid 5 with another drive (before it was 4x 3TB WD Red, now it's 5x). The raid array finished it's rebuild and it's clean.
Then I tried increasing the file system size - when I click on increase size and click ok nothing happens...
I waited a while - still no change.
After a while I get an error message:HTML
Alles anzeigen<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>500 Internal Server Error</title> </head><body> <h1>Internal Server Error</h1> <p>The server encountered an internal error or misconfiguration and was unable to complete your request.</p> <p>Please contact the server administrator, [no address given] and inform them of the time the error occurred, and anything you might have done that may have caused the error.</p> <p>More information about this error may be available in the server error log.</p> </body></html>
After that I rebooted the OMV and tried it again - still no change...
The OMV build is 0.4.38 (Fedaykin)Any idea what's going on?
Thanks
-
I did this already and it helped, but the array is still slower Ethan it should be.
I'll add another drive next month.
So hopefully the RAID works better with 5 drives.
But thank you anyways... -
No, it didn't - but I guess that's down to the individual client.
With my laptop I'm now able to achieve aroud 100MB/s read and write with one 1Gbit connection.
So it isn't the fault of the OMV...Next month I'll get another WD Red, so I have a 5 disk raid - so hopefully this will boost the write performance further more.
Thanks for your help guys!

After I increased the cache I get 156MB/s with the benchmark.
So helped a lot...
Would it make sense, to increase the cache even more? -
Alright, I'll give this a try...
What settings did you select for hard discs?
Did you enable the write cache? -
Zitat von "ryecoaaron"
What is the output of (change md127 to match your raid number):
cat /sys/block/md127/md/stripe_cache_size
The value is 256
So the cache size might be to small?
Zitat von "davidh2k"Alles anzeigenI would say your Atom has not enough power to calculate the parity with higher speeds.
There are some guidelines for RAID5 which means you should get a specific amount of hard disks (3, 5 or 9 disks) or you will get slower write speeds because the raid has to reread blocks and rewrite them which slows the RAID down.

Sorry, German only, the english wikipedia article is not as half as good as the german one.Greetings
DavidSo if I put in another drive I should be fine again?
I'll have a look at the article later (no problem - I'm german :lol: )
The test with the onboard NIC had the same result:
Read speed between 60MB/s and 70MB/s - I guess this will have something to do with this machine... -
I just tested copying with my laptop via lan:
I get around 105MB/s read and about 85MB/s write (some file as before).
Write is still a bit low, but I guess read won't get any better with one 1Gbit connection.I'll try the onboard NIC of my desktop computer now, and see what results I get there.
But I'm still concerned about the low raid write performance...

These are my system specs:

HDD: 1x Kingston SSDNow V+200 120GB (system drive), 4x WD Red 3TB (Raid5, ext4)Here are the raid details:

Hi,
here is the result for write:
102400+0 records in
102400+0 records out
102400000000 bytes (102 GB) copied, 1154.46 s, 88.7 MB/s88,7 MB/s is not that much - I would expect more from a RAID5 set with 4x WD Reds 3TB.
I'll start the read test now...
-
How long does this usually take?
The write is taking some time already.
CPU load is around 40% -45% during this test. -
Hi,
CPU load is around 10%, so there is nothing stressing the system...
It's both ways around 60MB/s - 70MB/s, testet it with the same file (around 4,4GB).
Where can I check my raid speed and how do I bench it?
ThanksRegards,
Sebastian -
Hi,
I recently upgraded my system because I wasn't able to pass 60MB/s with my Asus C60m1-i Mainboard (which runs a RAID5 with 4 3TB WD Reds).
It has a Realtek network chipset, which really sucks.So I thought let's do it the right way.
I bought an HP ProCurve 1810-8G and a Supermicro X7SPA-HF-D525 mainboard with a dual Intel 82574L NIC.
I enabled Link Aggregation for the NICs and trunked the 1810-8G's ports, which are connected to the board.
Also I enabled Jumbo Frames (on the switch, the OMV and the client pc, which got an Intel Gigabit CT NIC and runs Win7 Ultimate) and Flow Control.
But no matter what I try, I'm not able to get past 60-70MB/s.Do you have any tips for me, how to improve my transfer speed?
Thanks guys -
Sorry answering that late, I've been on a business trip...
I will replace my main board within the next weeks - so I will leave it as it is right now. I will have to reinstall then anyways.
I'll retry your script with my fresh install at this point.
Thanks for your efforts... -
Yes, of course...
I also used sudo - got the same result... -
Hi,
I tried the install script, but I getting the Forbidden access error...
Then I used the uninstall script and then installed again, still no change.
I also noticed, that the script failed to create the directory /var/www/owncloud - I had to create it manually before the install, otherwise the script would fail.What am I doing wrong?
Thanks
-
Nope, but I will try this now...
Thanks

Hi there,
I'm having some issues recently.
I was trying to install owncloud, but it failed, due to the dependency of php5.
But when I try to install php it tells me that it may not be installed.
Any ideas what's wrong there?Thanks a lot!
