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

The text below was part of a press release on the HGST website. It looks like the regulators shared your concerns about reduced competition.

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?

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.

If you have the space to do this then it is ideal. 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.

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. X7SPA-HF based small (perfect) server build Temperature based fan speed control?

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.

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.

@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.

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?

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?

Yeah, it looks like the Chinese need to get to work an a better translator. If that person's real name is Stacey then I'm the King of Siam!

In the US, where average electricity costs are about 10 cents per kwh, it is going to cost you about $1 per year to run your server 24x7 for every watt consumed. I don't know how much power your server will draw but mine draws about 40w when all the disks are spun down. So I figure it costs me about $40 to keep my server on at all times. I think it is well worth the convenience of having my data readily accessible.

Maybe if you were running a traditional RAID array and using the onboard controller bu that logic does not apply to unRAID. UnRAID can be run on just about any MB. I've swapped my MB 4 times in the past year without any hiccups. If your MB fails just get another one that is compatible with unRAID. A bigger thing to be worried about is a failed flash drive. That's why I keep a backup copy of my unraid flash drive offline.

I am using DeltaCopy as rsync server on Windows. I tried using DeltaCopy first but had trouble getting it working properly. The important thing is you just need to get rsync running on a windows machine somehow - it doesn't mater if it's DeltaCopy or cwrsync.
