You have to enable it (IOMMU / vt-d) in the BIOS.

You're right, I've never seen a Q08.

Buy some thumb screws! It'll at least lower your pain when you have to remove them.

Does this script Running /etc/my_init.d/99_chown_plex_owned_files.sh. really need to run at every start. It seems to chown my entire plex config folder, taking several minutes.

Your CPU still have to do all the work. RAM is only storage, no processing going on there. Right, but to expand on this further.... Plex tries to stay ahead when it transcodes... normally, it stores the transcoded file on the disk, adding some lag. By using this setup we can store it in RAM to speed up things.

If there is no cache drive and unRAID just cruises on ignoring that, then won't the appdata files eventually get spread out throughout the array drives? Maybe if jo cache drive, then set it to use disk1 only.

So things have changed a wee bit for me lately. I've since upgraded to unRAID 6 (on 6.0.1 currently), decommissioned my "app server" and started using dockers. My 2GB of ram was barely enough but I wanted to take a stab at using VM's as well. So I've upgraded to 8GB of Kingston HyperX Fury. I've mentioned this in other threads, but want to here as well. The MCE errors went away when I upgraded to unraid v6 so I suspect some legacy code in v5's linux version was the cause. I've also removed a WD 2TB Green from service (my cache drive) as it had a growing number of reallocated sectors and a pending that would not go away. I replaced it with a Seagate Momentus 5400.6 160GB laptop drive. A little slower but its in great shape and quiet/cool running. I also replaced my last 2TB array drive with a 3TB Red (my second one). This 2TB Green is still in good health (albeit with 30k hours) so I'm not sure what to do with it. I could preclear it and add it back into the array (it was showing NO signs of failure) or I could just leave it in there as a backup drive for important data using the unassigned devices plugin... hmmmm Now with more ram, dockers, and two VM's installed I'm thinking about putting a good video card in it and trying my hand at gaming! I just need to purchase a vt-d capable CPU (I KNOW gary will suggest the i7-4790). I'm considering an i5-4xxx series for some savings... I already have a nVidia 8800GT to test with, I'm just happy I chose the Q25B as it has space for a long double slot video card!

That screen shot once again shows that drives >2.2TB are reported as 2.2TB. Those are 4.0TB Seagate drives. EDIT: The mentioned 2.2TB bug is for the Unassigned Devices plugin, not this Preclear Plugin.

This file is part of the fast preclear that bjp999 created.

Installed a new 3TB WD Red drive today and when i click "start preclear" nothing happens.

Is bjp999's preclear script included in your plugin package or do we just pick which one and copy it to config\plugins\preclear.disk ?

Should be ok except for device passthrough. My setup is running v6 with 4 dockers. Only thing I'm changing is adding more ram. I'm running couchpotato, SickRage, transmission, and mariadb.

Roland, are you still getting the occasional Machine Check Errors. My setup (exactly as yours, but with a Celeron G1840 and I get the occasional MCE. I have not noticed any reduction or odd behaviour as a result. The problem solver in me wants to get to the bottom of it though. Cheers.

I really cant personally justify the price for 6TB vs 3TB or 4TB. In Canada the 6TB Red on sale is $340 vs $199 for 4TB and $135 for 3TB. I could nearly get three 3TB drives for the cost of a single 6TB drive!! The next logical step for me is to purchase a 4TB drive since the next replacement will get rid of my last 2TB drive in the system.

I'm thinking (hoping) that when unRAID 6 goes final it may resolve the MCE's, but otherwise I dont lose sleep over it I agree the Q26 looks really nice, but i dont need 10 drives (only have a plus license), and at my usage rates (currently only 67% full and its over 3 years old) its cheaper to just invest in larger drive sizes as needed. Currently I have 3x 3TB and 1x 2TB. My Parity drive is now a WD Red (these run so much cooler than the older WD Green).

4 months later and this server has never once let me down. I continue to see random MCE "Machine Check Errors" but there appears to be no adverse affects.

2002 was released after I last tried to update my BIOS. I'll give it a go next time I restart the server too. I'm currently on 2001 I believe, and one of the fixes listed on the website "Increase system stability". So it might actually solve these problems as on Windows OS's these are what cause BSOD I've read.

Sounds like a good plan. I went low end on the CPU and RAM because I have a separate box that handles all my "apps" like SickRage (Sikbeard), CouchPotato, Transmission, mySQL, etc. The first Parity Check completed in nearly the exact same time as the old setup, confirming proper performance with the new hardware.

Gary is right. its only a tight fit if you use an ATX. an SFX Unit like the one I used allows for plenty of space. Mine isn't even modular (chosen for what I believe are higher quality internal components).

No current photo's sorry. Not much to see other than a matte black box sitting on a shelf, which is exactly what i was aiming for. So far this server is rock solid. 33 days uptime, havent restarted it since i built it. Thinking about adding some capacity shortly, just need to do the math on what to get (4TB Parity, add 3TB drive, etc.) One thing i've run into is that I am seeing Machine Check Errors "MCE Error" and google suggests that a bios update may be in order. Im not overly worried as they dont seem to be causing any issues with normal operation. I think i've got 20 of them in the log.

my understanding with Docker is that it needs no special hardware like a Virtual Machine would (i.e. VT-d, etc.). I do not plan to run docker on this machine (currently running v5.0.5) but I dont forsee any issues with my current setup except perhaps available ram (although my ubuntu 14.04 server uses less than 500mb of ram and it runs SickRage, CouchPotato, Transmission, APCUPSd, ProFTPd). The bottom tray in the Q25 can hold a variety of drives but no more than two 3.5" drives and a single 2.5" drive at once.

Thanks for reading Spectator. 2gb seems plenty for me since I run it fairly lean on add-ons, using a separate machine for apps (an Asus Eeebox PC). I choose the Q25 over the DS380 for a couple of reasons. 1. Cost. The DS380 is nearly $100 more in Canada. 2. CPU cooler height spacing made me nervous. A lot who used the case used low profile coolers for the cpu, although I admit I don't know for sure. 3. Cooling. As you've already mentioned. 4. HD trays were mentioned as cheap plastic in several reviews. 5. The hard drive rack MAY block add on card access needed to support all 8 bays. The Q25 supports 5 hot swap and 2 "cold swap" in the lower tray. In addition you can add a 3rd drive in the tray as long as it is 2.5". Low and behold. I'm at 8 drives worth of capacity.

Final temperatures are in! I monitored the parity check throughout and the hottest drive was 38c and the cpu never went higher than 32c. Cooling in the Q25 is excellent! Also, the parity check finished in almost the exact same amount of time as my previous setup, which confirms to me that everything is working properly.

UPDATED: So I just finished assembling and setting up my new server using the following components: MB: Asus H87i-PLUS CPU: Celeron G1840 i5-4460 (2016-04-15) RAM: 2GB Crucial 2x4GB HyperX Fury (2016-04-15) CASE: Lian-Li PC-Q25B PSU: Silverstone SST-ST45SF (SFX, 450w, non-modular) HDD: Carry-over (Various WD 2TB and 3TB drives) GPU: HD5450 Passive (2016-04-15) My goal was simple. Reduce the footprint of my existing server (CoolerMaster CM 810) while maintaining the current array setup all the while allowing for slow future growth. Items before unpacking: Motherboard installed on removable tray: Motherboard tray installed in the case (the 2 black SATA cables would be swapped out later): While not pictured, I used 4 right-angled to right-angled SATA cables for the 4 ports on the edge of the motherboard. The ports were the proper direction and the backplane had adequate space for the downward turns. The more interior ports used straight to straight cables because the store I got my cables from was sold out of straight to right-angle, otherwise I would have got two of those. A parity check is currently going as a full bore test of the I/O and stability. it is at 7% at the time of writing and the hard drives are 35-37c. The top most slot contains my cache drive (which will be converted to a 2.5" drive that I already have, and moved to the bottom plate) and it is currently spun down, but temps were about 36c. This is an older 160GB drive though, so higher temps are expected. I set the USB mode to Hard Drive, and unraid boots in seconds (no joke), and this is on a USB 2.0 card reader to boot. Lessons Learned: Get the SFX PSU. I did right off the bat (while I seriously contemplated not doing so) based on the advice of Gary (garycase) and boy was he right! Even with the SFX PSU space was tight!! With this case/motherboard combination, get 2 RA to ST SATA cables (12") and 4 RA to RA SATA cables (9"). I might still pick up the RA to ST cables if I find some.

Thanks! I'm about to list my CM Stacker 810 up for sale (I simply don't need this much space) along with all the HDD cages (three 3-in-2's).
