So once Blue Iris writes a file it never has to access that file again?

I'm not sure I understand the question. Blue Iris is keeping the disk busy.

There should be no problem using tempfs in this manner as RAM allows. The more the better. How long is the warranty on a hybrid drive?

Check for a plugin update.

This one works: http://www.rakuten.com/prod/lexar-high-performance-16-gb-microsd-high-capacity-microsdhc-class-10/249372125.html?sku=249372125

Yes.

New config does not effect the contents of any of the drives.

6% is unacceptable. TCP should operate with less than 1% packet loss unless something is wrong with the network. UDP service like VOIP is not relevant unless the server is running a UDP service. This is most likely due to a bad physical connection.

A GUI to enable rsync service would be helpful. I currently modify /etc/rsyncd.conf and /etc/inetd.conf to enable the rsync server. A GUI for the rsync client client would also be nice. A simple feature that allows an entire data disk to be mirrored to a second server would be nice. Perhaps an extendible list that includes source and destination would be more flexible. I need to delete on the destination before syncing to get whole disk mirroring to work. This should also be an option.

SMART reports may reveal which disk is at fault after a parity check error.

Enter the name in lower case. It should still work. Windows is not case sensitive with user names.

N40L with new drives. One drive each is on SAS, AHCI SATA, and eSATA. These are fast drives.

I fit 3 SS-500 in an XCLIO Nighthawk and the door closes.

XCLIO Nighthawk $44.99 http://www.newegg.com/Product/Product.aspx?Item=N82E16811103030

XCLIO Nighthawk (9)

This has 2 12v rails. One has 14A and the other 15A. Assuming the 14A rail powers the drives plan according to the first post. 4 green drives maximum to be safe.

The drive is on a SASLP card. The 1.12 version started without complaint.

I don't understand why preclear is reporting a smartctl problem.

Try NFS on both machines. Disk Utility configures NFS auto-mounts. I've been able to resolve blocked write permissions by restarting my Mac.

Which version?

It could be a memory issue. Unfortunately, memtest does not detect all possible memory problems. Recently, a user with the same problem tested his memory for 9+ hours and found no problems. But when he used only one memory stick instead of two the problem went away.

A good PSU for unRaid has the following: 1. Single 12 volt rail. A subsequent figures refer to the 12 volt rail. 2. The minimum capacity that can power your build. Any more will just waste power. All drives will be in use during startup, shutdown, parity check, parity build, failed drive emulation, and drive rebuild, but startup requires the most power. 3. 2 amps (24 watts) per green drive and 3 amps (36 watts) per non-green drive on the 12 volt rail. 4. 5 amps (60 watts) for the motherboard on the 12 volt rail. Please make comments below and I will incorporate changes in to this post.
