  2. was any plugin set up to use the cache drive? which version are you using? if you are using version 5 and able to access the flash drive, back up those plg files and try rebooting without'em
  3. I had a similar issue.. Then found this thread: http://lime-technology.com/forum/index.php?topic=3999.0 First, run this command to see the current "min_free_kbytes" value. cat /proc/sys/vm/min_free_kbytes and go to this page http://dd.qc.ca/people.redhat.com/kernel/min_free_kbytes.html and figure out what it should be.. then run this echo #### > /proc/sys/vm/min_free_kbytes #### should be the number shown for your memory from the web page above. For example, if you have 4GB of ram, #### should be 8192 I have 16GB of ram. I think my original value was maybe somewhere in 3000, forgot to write it down.. I set min_free_kbytes to 16384. Also added that command line to go file to set that everytime it boots up. After that, I am not getting any kind of page allocation error in my log file.. I posted this another thread, but can someone explain what min_free_kbytes is for? and why unraid doe not set it to the default value as shown in that web page?
  4. The deal is actually really good, but just not sure if this is a good unraid build. I'd def. go for it if i needed a desktop.
  5. Okay. Just as a comparison, I don't use a cache drive, but I get the read speed of 80 - 90 mb/s and the write speed of 15 - 35 mb/s. If you get about what I get without a cache drive, even if you upgrade the mobo and other components, it may not improve too much.
  6. What's the write/read speed you are getting?
  7. It may be better for other people to help you if you can explain what you mean by 'not very responsive'. slow as in file transfer speed is slow? or slow as in you have some plug ins there that don't run too well? depending on which one it is, you may not have to upgrade the hardware too much
  8. Okay.. came home.. made sure all cables were secured. tested copying some files to my desktop from the unraid server, and then it started generating crazy errors in the syslog. and then.. i found this. http://lime-technology.com/forum/index.php?topic=3999.0 I set min_free_kbytes to 8192, then BAM no memory or page allocation errors... i am not too familiar with this side of linux.. what does min_free_kbytes do? also, found this page: http://dd.qc.ca/people.redhat.com/kernel/min_free_kbytes.html Looks like it should be set to 16384.. so i set min_free_kbytes to 16384 and then the whole performance of unraid machine improved. writing speed is between 20 mb/s and 40 mb/s without a cache drive, and read speed is over 80 mb/s Before I changed min_free_kbytes, i checked the value.. i dont remember what it was but it was in like 3k value.. so then i have new questions.. Why was min_free_kbytes set so low? or is it safe to set it at 16384?
  9. I see.. I will have to check cables when I get home. The drive itself is a bad drive though. it was causing a problem in my dad's desktop (problem with reading there too) but i just took it out and put it in the unraid machine. probably not a good idea haha.
  10. So.. now I am getting the correct speed for preclear and parity sync.. and no memory allocation error in the log. When the preclear and parity sync is done, i will have to run all other plugins to see if memory allocation error comes up again..
  11. Hi guys, I have an interesting problem that I am facing.. It's going to be a long story.. lol So, last week, I was able to get some great deal on ram (2 x 8GB for $39.99) and a 3tb hdd ($90). I didn't have time to do any setup for them last week so I put them in the machine this week. I replaced the ram, and added the hdd. Naturally, I went ahead and precleared the 3tb hdd. At this time there was no problem at all. I was running CouchPotato, maraschino, SABnzbd, SickBeard, MySQL Server, Subsonic, Transmission. They were all active. After preclear was done, I should have checked the parity first.. but I just went ahead and replaced the parity drive thinking everything will be okay.. and it started Parity-Sync. While it was in the process of parity sync.. again I thought everything will be okay, and went ahead and started preclearing the old parity drive (2tb) to use it as a data drive.. This is where everything started. During the parity sync, one of my hdd basically crapped out. It didn't have the red ball but its errors column was showing over 10,000,000 errors and parity sync kept going... It still had that green ball. I had no idea what to do, and thought maybe i should wait, so I waited until the parity sync was done with bunch of errors. error was shown only on the bad drive. However, I noticed that preclearing the 2tb hdd was extremely slow. Writing zero (step 2) was getting like 1.1MB/s. I wasn't sure what I had to do, so I just waited till the parity sync was done. When it was done with the parity sync, preclear's speed started going up again, so I thought there has to be a problem with that failed drive, but it was still showing "Green ball" after the parity sync. When I stopped the array, the failed disk was showing "unassigned" and it was saying the hdd was missing. I know i didn't touch anything in the machine, so i thought the hdd must've gone bad, so I turned off the machine (preclear wasn't done), plugged out the bad hdd, turned on the machine, and started the array without the failed disk. Luckily, the failed drive was old low capacity (500GB) hdd that didn't have any data yet, I was okay with just removing it) Since I turned off the machine when the preclear wasn't done, I restarted the preclear.. While the array was started without the disk, I was actively downloading something from SABnzbd, and the preclear was running. This is where another problem occurred. I was not able to access the server at all. NO webgui, no telnet. nothing. The server wasn't getting the ip address from the router. The machine was physically still on. On the server, I checked ifconfig and it seems to have the ipsetting.. First, I thought it had to do with the failed hdd, so i turned off the machine again, completely removed the failed hdd, then turned on the machine again. Since I added new ram as well, i thought it could be a problem with ram. so I ran memtest with the new ram. ran it for about 2 - 3 hours, did not have any problem and it passed 1 test. i exited out of memtest, rebooted, then I was able to access the server again.. Then again I started preclear (under screen) and started downloading some stuff from SABnzbd again.. However, this morning, i lost the access to the server again. ifconfig returned the correct address, but the router wasn't showing the machine as a connected device so i thought i should try renewing the ip address.. so i ran these commands: ifconfig eth0 down ifconfig eth0 up when i ran ifconfig eth0 up, i got this error SIOCSIFFLAGS: cannot allocate memory so i stopped preclear then exited out of 'screen'. when i ran ifconfig eth0 up, it set up the right ip address and i was able to access the server without a problem. I saved the syslog when this happened.. so the attached syslog is from this point. when i look at the syslog, it does seem like i have a lot of memory allocation error. I am guessing that there could've been a problem with parity-sync with failed drive.. so i ran the initconfig command to reset array.. and started rebuilding the array. I also thought there could be a problem with my plugins, so I disabled all plugins except for MySQL and subsonic. And I am running the preclear on 2tb again to see if I get that extremely slow preclear speed. so.. that's the story. lol in case you dont wan't to read my story.. lol here is my summed up question for you guys.. 1. What would cause preclear to run at 1MB/s? If the drive that i'm preclearing is bad, would preclear stop in the middle? or would it keep going and use lots of memory? 2. Can parity-sync with failed drive cause a problem like this? or does parity sync even work with a failed drive? 3. This was the first time that a drive failed on me.. what happens when a drive fails while the array was started? does it show bunch of errors in the error column like i saw? or just the redball? syslog_11292012.zip
  12. Thanks guys! Only con about this set up is the board itself. Only 4 Sata ports.. but with PCIe sata cards, I don't worry too much about it lol
  13. Hi Guys! I've posted this in XBMC forum long time ago, but I thought I would share it with you guys too! The spec below is what I have in the machine right now.. I did spend extra money to buy some other ram + Sata controller, but I don't have them in the machine anymore so I took them out of the calculation. So here is what I got: Motherboard: ECS H61H2-M2(1.0) ($44.99 - $30.00 @ NE) - http://www.newegg.com/Product/Product.aspx?Item=N82E16813135288 CPU: Intel G530 ($37.09 @ MC) - http://www.newegg.com/Product/Product.aspx?Item=N82E16819116409 PSU: Corsair CX430 V2 ($39.99 - $20.00 = $19.99) - http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026 RAM: G.SKILL Ripjaws X 16GB (2 x 8GB) ($39.99 @ NE) - http://www.newegg.com/Product/Product.aspx?Item=N82E16820231528 Case: Zalman Z9 ($37.09 - $10.00 @ MC) - http://www.newegg.com/Product/Product.aspx?Item=N82E16811235026 SATA Controller: SUPERMICRO AOC-SASLP-MV8 ($44.99 @ NE) - http://www.newegg.com/Product/Product.aspx?Item=N82E16816101358R HDD Cage: Vantec HDC-800A x 2 ($23.99 * 2 @ AZ) - http://www.amazon.com/gp/product/B004IYJWW6/ref=oh_details_o06_s01_i00 SATA Power Cable: Silverstone CP06 ($9.99 @ AZ) - http://www.amazon.com/gp/product/B005DD28XG/ref=oh_details_o06_s00_i00 SAS to SATA Cable: Monoprice Cable ($8.80 * 2 @ MO) - http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10254&cs_id=1025406&p_id=8187 Total Paid: $44.99 + 37.09 + 39.99 + 39.99 + 37.09 + 44.99 + ($23.99 * 2) + 9.99 + ($8.80 * 2) = $319.71 After Rebate: $319.71 - $30 - $20 - 10 = $259.71 (Received all my rebates as of last month) Amazon Gift Card: $259.71 - (23.99 *2) - 9.90 = $201.83 I actually had some Amazon Gift Cards.. I used that to buy the hdd cage and sata power cable.. so basically got the SATA Power cable and HDD Cage for free. I had a lot of extra sata cables and Molex to Sata cables.. but I would estimate that they would be $15 to $20 max. So, I was able to build a Server capable of handling total of 12 drives for about $250. Here is an old pic.. It has my old 4gb ram and extra SATA controllers that i dont use anymore.. and hdd's are upside down lol I will take a new picture soon and post it. What do you think?
  14. $30 off today only with promo code: CYBERMNDY64 20% was better.. because it'd take off about $36. Oh well.
  15. Wish this had the rebate too.. http://www.newegg.com/Product/Product.aspx?Item=N82E16811147165 I want that 12 hot swap drives..
  16. http://www.amazon.com/Seagate-Barracuda-3-5-Inch-Internal-ST3000DM001/dp/B005T3GRLY/ Amazon price matched it
  17. Well, this happened to me yesterday when I upgraded my laptop and htpc to Win 8. For me, I was basically able to get to unraid server using \\Tower\ only like half of the time. Actually, it happened to me awhile ago too.. and the fix is disabling IPv6 in the NIC Properties. I heard something about Samba's name and IPv6 having some problems. Do this on the machine that you are using to access the unraid machine.
  18. You have to use the promo code mentioned in the op
  19. This is what I'm wondering too. I have a gigabit router that gets the gigabit connection.. but I feel like it's not getting the speed that I am expecting it to get.. I get roughly 14 - 16 mb/s when transferring data to unraid machine. I understand that's normal, but the problem I'm having is the speed from the machine. I sometimes get below 10 mb/s.. but then sometimes it goes over 70 mb/s.. I thought it could be a problem with hdd's, but then the speed is not really constant for same files either... This is why I'm guessing that my router may have a slight problem. For $25 though.. maybe I should just go for it.
  20. I managed to order this today.. If the full bracket is not included in this "OPEN BOX".. does anyone know where i can get one?
  21. I got A-3500 for my gf! running openelec though. Without changing much settings, it is awesome.
