I had already checked the spinup groups possibility and I do not have spinup groups enabled so it must be due to something writing to a data disk. I've got inotify running now I'll just have to wait and see. Thanks Joe.

I'm seeing numerous instances of my parity drive spinning down in my syslog. I do not have a chache drive and there were no writes to my server in the same timeframe so the parity drive never should have spun up in the first place. I think it may be associated with a XMBC client accessing the library but I'm not 100% sure. How can I find out what is causing the parity drive to spin up? Syslog is attached.

So I found that the recycle bin was corrupted on the drive I was trying to backup. Fixed that but the slow transfers remain. I also added the --bwlimit=100000 argument to my rsync command to see if somehow it was being limited and that (not surprisingly) made no difference whatsoever. So I'm pretty much stumped at this point. Google has not been very helpful although maybe I'm not searching for the correct terms. Anyone have any ideas on how I can figure out what my problem is?

I've been using rsync to backup files from my desktop to my unraid server. I'm running win7 on my desktop so I'm using DeltaCopy as a frontend for rsync. I've been using it without any problems for a while now. My desktop is setup as the rsync server and the unraid server is the client. Today when I ran a backup from unraid it's only copying at 100 kB/sec. I'm copying a bunch of photos so there are hundreds of files that are 3-4 MBs and every one is copying at 100 kB/sec almost as if I was using the bandwidth limit option but I am not. If I use teracopy and manually copy files between the same directories I see 25-30 MB/sec. I can't figure out what is causing the slow transfers. Anyone have a suggestion on how I can figure this out?
In case it helps the command I'm using to launch the backup is:
rsync -avP --delete --chmod=Fo-X

This, unfortunately, is the byproduct of the WD buyout. I can't for the life of me understand how this wasn't considered a monopolistic maneuver and stopped by the FTC. Add the Seagate purchase of Samsungs HDD division, and we're left with... well, crap (WD) or crap (Seagate) in the 3.5" consumer market. Sprinkle a little mother nature in the mix (last year's flooding in Thailand), and you get the perfect storm of price fixing and slower production.
The text below was part of a press release on the HGST website. It looks like the regulators shared your concerns about reduced competition.
Regulatory Approvals: In connection with obtaining the regulatory approvals required to complete the acquisition of HGST, WD agreed, (i) subject to review by regulatory agencies in certain jurisdictions, to divest certain assets to Toshiba Corporation that will enable Toshiba to manufacture 3.5-inch hard drives for the desktop and consumer electronics markets and will expand Toshiba's capacity to manufacture and sell 3.5-inch hard drives for near-line (business critical) applications and (ii) to conditions required by the Chinese Ministry of Commerce ("MOFCOM") including adopting measures to keep HGST as an independent competitor until MOFCOM agrees otherwise (the minimum period is two years). Compliance with these undertakings may limit synergies that could otherwise be achieved and involve significant costs or require changes in business practices that result in reduced revenue. -
All the comments above are in agreement with my personal experience. You want the opening in front of your drives to be either the only inlet or only outlet for the entire case. This will ensure that all the air flow passes across your drives. Also, that opening should be no larger than the footprint of your installed drives otherwise a large proportion of the the airflow will just bypass your drives.
Another suggestion I would offer is to explore pwm controlled fans and temperature based fan speed control. I use it and it works wonderfully in my case (Antec 300). This allows you to adjust the air flow across your drives based upon their temps. Here are a few threads to read if you are interested.
Temperature based fan speed control?

Does this unit play 1080p high bitrate mkv using xbox media center. Have been unable to get it to do high bitrate 1080p running windows 7
I do not have this device but from everything I've read on the XBMC forums an ION should handle high bitrate 1080p just fine as long as you have DXVA enabled.

I only have one copy of movies, TV shows, & music and this is on my unraid server. Important documents, photos, home videos are stored on my main desktop PC (Win 7 home premium) and I use rsync to automatically backup these files to unraid. In order to do this I had to install deltacopy on the windows machine which is basically rsync ported to windows. Now that I have everything setup it works just as I wanted. I plan on setting up offsite backup (e.g. crashplan) when I convert to 5.0 when it's released.
Search the forums for deltacopy and you'll find a few useful threads on how to set it up.

Yes, the web GUI will show progress. The time required to compute parity depends on the size of your parity drive not how much data you have. An array with a 2TB parity drive normally takes 7-8 hours (if you are using green drives). If you are using a 3TB parity drive then I'd expect it to take 10-12 hours to compute parity.OK thanks. I have right around 2TB or so data so how long will that take to establish parity? I assume the web gui will show me progress?
-
If you have the space to do this then it is ideal.Fwiw, I am keeping all my media on my local PC until unRAID is good to go.
As bjp said previously there is a benefit to establishing parity first and then copying all the data over. The downside is that it will take longer to copy over the data but it may be worthwhile to take a little extra time now and take all the steps you can to make sure that the array is in good condition. There is nothing wrong with the method you mentioned - copy data first then establish parity - and I personally followed that method when I first setup my array.As to my other question, is it a good idea to copy over my data and then create the parity drive? Or vice versa?

I don't know of any add-on but you can use a script to have the motherboard controller do it as long as you have pwm fans. If you don't have pwm fans then you'd need a fan controller and you'd have to write some custom s/w to interface with it. I didn't want to do that so I got a pwm fan and used my MB controller. Check out the following threads for more info. I followed these threads and it works for me.

Something seems strange here. Both tests showed speeds of <15 MB/sec which is actually pretty poor. I have all green drives in my server and I typically see write speeds in the 25MB/sec range. The only way you would see an increase in write speeds is if the data disk AND the parity disk were both 7200 rpm drives. Black drives may very well be faster than Green drives but I suspect that there is something else going on here.

Looks good to me. I was already leaning towards monoprice but thanks to all for confirming that.

I'm in the process of upgrading my home network. When I first wired my network I just installed a connector at the end of the cable run and plugged it directly into my switch. This time I'd like to use a patch panel to clean things up a bit. I'd like to get a Cat6 16-port panel. Any suggestions?
-
You are correct but in order to see those options you must first select the Custom option for quality and then you can specify the Initial and Archive settings.2. When you set up the shows there are two options for the quality "Initial" and "Archive". If you set initial to 720p and archive to 1080p it will behave as you described. If you've already set up a show click on it from the home page and hit edit. You'll see the options there.

You will be able to see the raw results of the SMART tests in your syslog. All you really need to do is check to see if you have any change in the pending or reallocated sectors count. If you do then you'll need to decide if you want to run more preclears or RMA the drive.
-
With the basic version you are limited to three drives in the array but you can have an unlimited number of drives outside of the array. So since any drive you would be preclearing would not be assigned to the array you can do this without any problem. I have done this myself so I can confirm that it works just fine.My question is: Can I preclear drives in the current configuration without removing one of the drives in the array which would bring the drive count below three for the Basic version?
-
@TomAdam - Take a look at my post from earlier in this thread here. I have a different Supermicro MB (C2SEE) than you but I'd bet that the pwm control logic is probably the same. What I've found is that the fan is what determines if you can command it to zero speed. The first fan I used would not go below 700 rpm but now I'm using a Delta pwm fan and it can be commanded to zero speed.
-
I found the full preclear results thanks to the above post by Joe L. Is everything fine?
Looking at what you provided I cannot tell if that is the pre or post SMART report. However the fact that your disk reports 25 power on hours leads me to believe that it is the post-read assessment. If the info you posted is in fact the SMART report from the post-read then your disk is good (no reallocated or pending sectors).

The reason that drive prices are so high is because they are in very short supply. If you need to replace one of your drives under warranty then I would be prepared to wait a lot longer than normal. What do you think the OEMs will do with their limited supply, use them as replacements or sell them for a larger than normal profit?No one agreed with me when I said I really only buy drives with a 5 year warranty. For those with multiple drives out of warranty or warranties coming to an end aren't going to be in good situation. At least I'll have a couple extra years to wait out the issues and be "protected" in not having to buy drives at an inflated price right now.

I followed the link that bubbaQ posted, read the first paragraph and came to this statement, "Filled with 10TB or 12TB of raw storage, my test systems ranged in price from $1,699 to $3,799." That was enough for me so I closed the window and chuckled to myself.

@UhClem - apparently you did not understand my attempt at humor.

You only want 3TB support. I'd prefer 3TB+ support myself.

Just a guess here but is it possible that you have that SATA port configured as IDE in the BIOS?

Release 5.0 final and start working on a 64-bit upgrade but limit it to just that. Don't add any other capability because that will lengthen the development time, just convert to 64-bit kernel.
FWIW - This is why there should have been a 4.8 release to add support for >2TB drives. That could have been released a long time ago. There was a poll way back where the users voted to include a whole host of new features rather than simply add >2TB support yet reading through this thread most people supported a 5.0 final release because we need to have >2TB support.
