May 31, 201313 yr Oddly, enough it just started working. Everything is on the same workgroup, and you are right I should change it off default. Another question, as far as a UPS for this, any recommendations on brand, size, etc. Thanks. r.e. UPS Whatever you get, be sure it has AVR (automatic voltage regulation). Both APC and CyberPower make nice units at reasonable prices. These are a few good choices: http://www.newegg.com/Product/Product.aspx?Item=N82E16842101381 http://www.newegg.com/Product/Product.aspx?Item=N82E16842101393 http://www.newegg.com/Product/Product.aspx?Item=N82E16842102048
June 1, 201313 yr Author Gary, thanks for the constant feedback. This has greatly helped. a few more questions 1. for the UPS, is it ok that it is lower wattage than the power supply on the computer? I have a 650w on the tower, and i think the first UPS in your links was 450W. 2. I had the following error, at the time, two things were going on. (a. two drives were being precleared, b. i was moving over data from elsewhere on the network).. Any ideas on what caused it, how to prevent it, is there something i should be worried about ? 1897841061888 bytes (1.9 TB) copied, 13944.7 s, 136 MB/s Wrote 1,897,841,061,888 bytes out of 3,000,592,982,016 bytes (63% Done) Message from syslogd@Tartaros at Sat Jun 1 05:37:44 2013 ...

June 1, 201313 yr 1. for the UPS, is it ok that it is lower wattage than the power supply on the computer? I have a 650w on the tower, and i think the first UPS in your links was 450W. That UPS is almost certainly fine. Your PSU is rated for 650w, but I can assure you that's overkill ... you're not drawing anywhere near that !! If you want to confirm what you really draw, get a Kill-a-Watt and measure your actual power consumption. This is a very-handy-to-have gadget anyway. http://www.amazon.com/P3-International-P4400-Electricity-Monitor/dp/B00009MDBU/ref=sr_1_1?s=electronics&ie=UTF8&qid=1370128283&sr=1-1&keywords=kill+a+watt 2. I had the following error, at the time, two things were going on. (a. two drives were being precleared, b. i was moving over data from elsewhere on the network).. Any ideas on what caused it, how to prevent it, is there something i should be worried about ? I'm afraid I have no idea what this error means. Were you able to complete the copy okay? If so, you're probably okay, although I'd run a comparison between the data you were copying and the copy on UnRAID, just to be sure. I think it's a Putty error (were you using Putty?) ... in any event, hopefully a Linux expert will chime in and let you know what the errors really mean.
June 2, 201313 yr Author Thanks for the info. I will grab a kill a watt since I've heard a lot of references to that over the boards. As far as the error, i was using putty, but i'm wondering if something is wrong with the new drives i installed (2x 320 GB, and a 1x 1TB). I believe the first two are pretty old, as in 2005 timeframe. The reason i'm suspecting this is a. the 'crash' which produced the error i posted and the freezing of the system which required a reboot has only happened once, which is after these drives were put in. It has not happened again since I originally posted it b. while trying to copy a bunch of data from some other external drives, the whole array becomes unavailable. I'm wondering if these drives are going to sleep or what. also another question, i noticed while i was trying to troubleshoot the 'crash', that there were basically no syslog data, and it only kept everything since i booted it back up (i had to power cycle the box). is there a way to configure this to save this data and roll the logs, gzip/tar them, etc. so that i can go back for historical data. thanks.
June 2, 201313 yr There are all sorts of things that can cause system instability. Too many processes for amount of RAM installed, bad memory, weak power supply, mutiple power rail power supply - 1 runs out of power because the rails do not actually share the load and may cause a voltage supply dip - much like a weak or failing power supply may do..., plus many others... Your symptoms, seem to me, more likely power supply releated. In all my marginal hardware testing to determine failure modes, most commonly I have had messages such as yours with bad, weak, and failing power supplies. In only one instance have I seen your symptoms occur with a memory issue, I had a bad stick of RAM. If you have another power supply you can try it may be worth it, then also run a full 24 hours of the memory test that is available when first booting from the unRAID flash drive. Syslog is stored in RAM in a temporary virtual drive by default. There are a couple other threads where people have re-directed it to a cache drive, or a second flash drive, (to prevent excessive wear on the precious unRAID boot flash... There are a few ways to do it, sorry I do not have the time to search a bit right now, since I can not think of where I saw them right off hand. If I remember correctly, most people seem to end up adding to the 'go' script to make it go to a real storage location so the log is available even after a power down... ok... found a good link about saving syslogs... http://lime-technology.com/forum/index.php?topic=5568.msg60626#msg60626 Hope that will all help!
June 7, 201313 yr Author Another question, i'm trying to hook up all the fans that came with the antec 1200 case, and i've notice that i'm taking out 2 in the front so i could put in the hard drive cages, which i'm hoping doesn't cause some cooling issue down the line. Also, the other fans other than the cpu fan have 3 pin female connecters and the connectors on the motherboard seem to be 4 pin connectors. do i just use 3 of 4 ? this is for the MBD-X9SCM-F-O supermicro motherboard. thanks as always.

Check out the warning on page 2-26 of the manual before you mix your fan headers - 3 pin and 4 pin (PWM). I had an ASUS MB that had a 4 pin PWM CPU fan header and the rest were 3 pin so you were encouraged to mix them. But SuperMicro advises against it for the X9SCM.
June 8, 201313 yr I guess Antec changed things... My Antec 1200 cases get power directly from the power supply with the old large 4-pin molex connectors, then have little switches on them to set the speed at low, medium, or high... Little fan power adapters are readily available to power a three pin fan from the power supply, but the fans would then scream at full speed! I would suggest a basic fan controller, (antec may have the old switch option available still - but now as an add-on instead of standard, but I can't seem to find it...) Here is one option, though not really adjustable, it can 4-fans! 2 at full speed, two at low speed! It may work as you would like, PLUS it is cheap! :-) http://www.newegg.com/Product/Product.aspx?Item=N82E16812311003 This second one runs the fan (ONE ONLY) at full speed only, but also will send the fan speed signal back to the mother board. http://www.newegg.com/Product/Product.aspx?Item=N82E16812189119 Any other more costly options may be nice, but also eat up space where a drive could go typically...
June 8, 201313 yr If you have an available 5.25" bay, buy one of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16811992007 If not, buy one of these and mount it in an unused expansion slot on the back: http://www.frozencpu.com/products/10613/cpa-338/Lian_Li_PT-FN02_Expansion_Slot_Triple_Fan_Controller_-_Black_PT-FN02B.html?tl=g34c17s1375&id=UHG6sadr
