February 11, 201412 yr Since I didn't get a chance to test and report my findings for the new "reconstruct-writes" option ("mdcmd set md_write_method 1") under 5.0.3, I figured I should post it here now that I'm running 5.0.5. I have my Plus license maxed out with six WD 2TB Green drives (WD20EARS) connected to the onboard SATA ports on my MSI H55M-ED55 motherboard paired with an Intel Core i3-550 processor and 8GB of RAM. Testing with a 15GB MKV file I saw my writes jump from about 20-22 MB/sec to 40-45 MB/sec according to the Windows 7 Pro file copy progress window. Needless to say, I love the 2x speed increase from this option!

Needless to say, I love the 2x speed increase from this option! I use it on a daily basis. I have an rc script that adds a cron entry to turn it on and off by schedule. root@unRAID:/boot/local/etc/rc.d# cat /boot/config/write_method.crontab 00 08 * * * /root/mdcmd set md_write_method 1 00 00 * * * /root/mdcmd set md_write_method 0 One of these days I'll even get a package to do this automatically. I'm just so dam busy this first quarter of the year.

February 11, 201412 yr Author Quick question.. why would you turn this on and off if it results in a performance increase? Sent from my Nexus 5 using Tapatalk Because it requires all your drives to be spun up. Also, as your array width increases it will hit a point where this method is no longer faster, and in fact will start being slower. This will also depend on your H/W (bus speed, ram speed).

So for a two drive system (one parity and one data drive) would it be advisable to leave this option always enabled?

A 2-drive server is a degenerate case and I think the code automatically uses this transfer mode.
February 11, 201412 yr Ah, that would explain the speedup in writes that I have noticed over the last few releases. Thanks for the explanation.

Also, as your array width increases it will hit a point where this method is no longer faster, and in fact will start being slower. This will also depend on your H/W (bus speed, ram speed). FWIW, I use one of my unraid servers very heavily. It is torrenting and where it stores all the stream rips. I then go in, tag, rename and move them to the appropriate locations with mp3tag. I operate on many small files(by video standards) at once. So with all the kernel tunings and this new mode, I'm able to keep my ssd from being beaten on and have close to native SATA speed over the lan. I have another cron job that writes to the array during my busy part of the data once an hour to keep all drives spun up. The speed increase is a welcome update for these small array width short burst writes (along with some kernel tunings). The only time I have an issue with it is when I start a torrent that starts downloading at a very high rate. Then it can make everything lag. FWIW I really do beat the hell out of my unraid server. And it's only an N40L. I can't wait for x64 and 16GB of ram to see how well it performs.
February 12, 201412 yr I'm still waiting for the improved new webgui, which Tom has said will be included in the 5.06 release. Are any of you using the new gui with 5.05 without issues? Also, does the new gui include anything NEW?
February 18, 201412 yr WoW!! I am way behind. I'm still using 5.0 final from last year. I'll need to upgrade my unRAID boxes sometime to this version. From what I read there shouldn't be any issues right? Just a straight upgrade by copying the three files in the instructions? I need to remember to backup my drive list and the flash drive files first.
February 19, 201412 yr This was posted a few pages back but I didn't see any other comments. Has anyone else noticed their server stopped beeping when the array comes online? My server still beeps on shutdown but there's no beeps on startup. I can't remember which version of 5.0 Final this started happening (either 5.0.4 or 5.0.5)?! EDIT: I guess it was 5.0.4 for me. http://lime-technology.com/forum/index.php?topic=31472.msg286542#msg286542

I only have two beeps when rebooting or shutting down. Maybe you had a "beep" in your go script or in a plugin that u used? (<- this is also the way to get it back fyi )

I also noticed today when I rebooted my server that it no longer does this. Any way to get this back, bar downgrading unRAID version? ;-) Sent from my Nexus 5 using Tapatalk

I just recall the server beeping when the array became available. I can't remember if it was two or three beeps but I do know whenever I would send a magic packet to turn it on that I would wait for the beeps before trying to access my share and it worked every time. Now sometimes my media player hangs if I initiate the mount too quickly...
February 21, 201412 yr A long time ago there was a long debate about beep codes but I think it was during a Limetech dry patch. A list of beep codes and some sort of daemon is still a great idea in my book.
February 21, 201412 yr A list of beep codes and some sort of daemon is still a great idea in my book. +1 for this.
February 22, 201412 yr If I remember correctly to get the beep back one adds an appropriate command at the end of the go Giles. However I cannot remember the details of the command required.
March 7, 201412 yr If I remember correctly to get the beep back one adds an appropriate command at the end of the go Giles. However I cannot remember the details of the command required. I see these two threads: http://lime-technology.com/forum/index.php?topic=25047.0 http://lime-technology.com/forum/index.php?topic=10749.0 Haven't tried any of it on my system recently, though. HTH?
March 8, 201412 yr So, while I didn't modify my 'go' file (and thus didn't reboot my system), when I enter something like "beep -f660 -l100ms -D 130ms" in a telnet prompt, the system produces a sound ... so it would appear this is working on 5.0.5? I don't know why it would behave any differently in a 'go' script ... but you're welcome to test at the command line yourselves.
March 16, 201412 yr Hi i've got unraid version: 5.0-rc8a what are the steps to upgrade to the latest?
March 16, 201412 yr Read the first post in this thread: http://lime-technology.com/forum/index.php?topic=29096.0 Depending on what you plugins you have installed, you might be able to use the the update instructions for rc16c. The reason for the reformatting of the flash is because there are plugins that are NOT compatible with ver. 5.0.X.
March 25, 201412 yr getting a new issue - running 5.0.5 for weeks now. Today I rebooted, and my system hangs and on the console the last line says: ACPI: All ACPI Tables successfully acquired" I have not touched hardware at all. Everything has been running for 3 years on same hardware without any issues. I took flash drive out, did chkdsk - no errors, even restored my flash drive files from a few months ago, same result. So can somebody tell me if this is related to 5..05 or perhaps something else? I have been running unraid for 5 years, and this is the first time server will not start

I have been running unraid for 5 years, and this is the first time server will not start This should probably be split off, to a support board. There's no apparent connection with v5.0.5. It sounds like a hardware failure of some kind to me. First, try a memtest, one full pass. And make sure all fans are spinning, especially the CPU fan.
March 26, 201412 yr I agree, not appropriate for here - just as a fyi, after a couple reboots - Hard Resets, the issue has gone away. booted 10x now with normal results, weird. Will post in support section if it returns.
