Yes it was excluded after the share was created, it was a disk added after the share was created.

I have shares copying to excluded drives, they are set to copy to most free but periodically copy to excluded drives. Any ideas why?

I opened the case and reseated all the cables. It rebuilt the parity and looks good so far. I'm thinking if I'm gonna have issues they will arise when I write to the array not when I am just reading from it. I'll write something to it later today.

Could this be part of the problem? parity device: pci-0000:00:1f.2-scsi-0:0:0:0 host1 (sda) ST2000DL003-9VT166_5YD2Z590 disk1 device: pci-0000:00:1f.5-scsi-1:0:0:0 host4 (sdf) ST2000DL003-9VT166_5YD2TKNM disk2 device: pci-0000:00:1f.2-scsi-1:0:1:0 host2 (sdd) ST2000DL003-9VT166_5YD2Y1K5 disk3 device: pci-0000:00:1f.5-scsi-0:0:0:0 host3 (sde) ST2000DL003-9VT166_5YD2VWT7 disk4 device: pci-0000:00:1f.2-scsi-0:0:1:0 host1 (sdb) ST2000DL003-9VT166_5YD28YGC disk5 device: pci-0000:00:1f.2-scsi-1:0:0:0 host2 (sdc) ST2000DL003-9VT166_5YD31EBL It's showing 2 disks on Host 1 and 2 disks on Host 2

I am back where I started, Parity disk showing as new and rebuilding again. Appears to be having issues with disk 4 as well.

I stopped the array, shutdown the serger and re-seated the drive. It restarted without any errors and I was able to do the short smart test, it showed no errors. Hopefully that was the problem.

Now I get this error when trying to run the short smart test from unmenu smartctl -t short -d ata /dev/sda 2>&1 smartctl 5.39.1 2010-01-28 r3054 [i486-slackware-linux-gnu] (local build) Copyright © 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net Smartctl: Device Read Identity Failed (not an ATA/ATAPI device) A mandatory SMART command failed: exiting. To continue, add one or more '-T permissive' options. HELP!

Actually it looks like I may have a problem with the parity disk.

I let the parity re-synch(completed with no errors) shut the server down for the night and when I started this morning all was well.

I'm running identical hardware to the 20 drive Tower from Raj. I haven't added the controller cards yet so I have all 6 drives connected to the motherboard. The drives are Seagate Barracuda Greens 2TB, all were successfully precleared before being added to the array. I rebooted the server after I got the error and the syslog reset and only has entries since after the reboot so I don't think that will be much help. It is rebuilding the parity on the same original parity disk right now. I just wonder if moving and deleting folders from one share to another as well as reassigning the disks to the shares might have screwed things up.

I have had UnRaid 4.7 running for a few days. I added the parity disk a couple of days ago and today (after moving one folder from one disk to another )it showed as a new disk and is rebuilding parity again after a reboot of the server. Any clues as to why?

Thanks Alot, feel a little dumb but thats ok.

I can't see a link to get the preclear script, am I missing something?

OK, they wanted $56 to ship 3 cables to Canada so I found them at a Canadian site for $19 each and $7 total shipping. Thanks again for your help. Don't be surprised if I'm on here looking for more guidance later.

Johnm Thanks for the reply, just to be clear I need 4 of these, 3ware CBL-SFF8087OCF-05M Multi-lane Internal (SFF-8087) Serial ATA breakout cable ? The cables are the last thing I have to sort out and get ordered. I ordered one of these already so hopefully they are the right ones and I will get 3 more.

I'm ordering parts from Raj's 20 Drive Budget Build (rackmount) but ordered a Norco 4020 case instead of the 4220, what cables will I need with this case?

Anyone know where you can get one in Canada, the vendor doesn't ship to Canada.

I forgot the Asus board is $50 cheaper.

Which of these 2 board would be better for a system with the following specs? SUPERMICRO MBD-C2SEA-O LGA 775 Intel G45 HDMI ATX Intel Motherboard Asus A78LT-M LE I will be using..... Norco 4220 Case Corsair Enthusiast Series TX650 V2 650 Watt Power Supply I would start with 6 Green 2TB drives with room for expansion.

Would there be a downside to using this PS with a Norco 4020 case and possibly 15-20 drives? Corsair Enthusiast Series TX850 V2 I am able to get it for $100

This is what I'm thinkg so far..... Motherboard - ASUS M4A78LT-M CPU - AMD Athlon 2 255 Power Supply - Corsair HX 650 Case - Antec 1200 V3 Ram - 4GB Supermicro AOC-SASLP-MV8 Marvell 6480 8 Channel SAS/SATA RAID PCI-E Card Other than cables and the Hard Drives will this allow me to start with 8-10 drives? Thanks

Would either of these 2 cases be a good choice for a new unraid server? http://www.coolermaster-usa.com/product.php?product_id=2950 http://www.coolermaster.com/product.php?product_id=6653 Which would bew a better choice? Thanks
