*feedback* original file(from pc) : 1df3467443cef371a72f3f2df4a05b6f copied file(from pc) : 1df3467443cef371a72f3f2df4a05b6f file on mnt(unraid) : 1df3467443cef371a72f3f2df4a05b6f Thus its not on MD5 /file contents level - all matches I am not sure if testing the memory of the PC is going to help, as since mentioned in my previous post, i determined its something to do with the source files (the same files keeps failing to copy) copying from three different machines to unraid produces teh same results with the same files... I have since noticed a very odd similar characteristic on the failing files : Date modified is 01 ?January ?2098, ??12:00:00 AM once i copy it over to unraid - ls -lt shows that the file is updated to 2038-01-19 03:14 and then copying it back to windows just makes matter worse - date modified just doesn't show up at all(explorer GUI), and VLC player is not capable of opening the file anymore. from the windows pc command prompt dir /TW sp*.* reports : Volume in drive J is BEEEG Volume Serial Number is E27F-6551 Directory of J:\ 2098/01/01 12:00 AM 183 437 312 sp1.avi 1601/01/01 02:00 AM 183 437 312 sp1_.avi 2 File(s) 366 874 624 bytes sp1.avi - orginal file sp1_.avi - file after return copying it from unraid back to windows ( i get the same result from a mapped drive) This is the first time i encounter something like this.... yes most probably the issues starts on the source file having a future modified date. any thoughts? Thx Neo_x

Both very excellent ideas. Compeltely forgot about the MD5 possibility willl try it and report back once done thx Joe / Lionel much appreciated

Hi guys sorry for the taking this long to reply - had been busy after finalizing most of the tests mentioned in previous posts (ie recreating, and testing on a different NIC etc etc) -i am still facing issues with file corruption strange part - file size etc matches, but detailed view from a windows client doesnt show a date modified. EVEN STRANGER PART - AND I TESTED THIS WITH A FEW CORRUPT FILES if i delete a culprit file, and recopy it (doesn't matter from which client - i tried three (media center, other server and a Core i7 laptop) no improvement - Tercaopy with CRC check enabled doesnt pick up anything strange. trying to open the same video from VLC -shows the file is corrupt (doesn't even start to play it. ) as mentioned - i tried different NIC's and even direct LAN cables - no change- same file(s) corrupts every single time - and this is for roughly 20GB / 1.2TB of data. for example - i have a complete season of a specific show refusing to reproduce on the UNRAID share i am completely at a loss, as i haven't seen consistent failures to copy to another machine in my 18 year of working on a PC - there is always something random that goes wrong if its for example a mermory/board issue - this time around - it just sticks me the finger when i try and re-copy a file can anyone recommend what other ways i can try to isolate the issue? ideas i have (except no clue on how to implement) : * mount/share a drive directly on the unraid (without having it in the array) - and test copy like that (maybe its specific drives?) * try and virtualize the UNRAID? ( Notice Johnm managed... so shouldn't be all the impossible) * don't exactly want to go this route - as it will complicate a few things , but if it guarantees data validity, i am all for it otherwise - i am really at wits end - will have to try alternate solutions(MDADM?), until such time as i can afford to buy more compatible hardware thx in advance for any constructive ideas Neo_x

Trying this now. And second most suspect is the network card (believe it or not) We've had other members with similar problems, and the network card was involved in several... As stated though, memory is the most likely. ok. since i have the luxury of still having the data on another machine,i figure i will try and start form a clean rc3, and test the functionality there. (i will also try using teracopy - CRC check - altho i doubt that windows copy can corrupt files wrt to the extra NIC - i can test it as a temporary measure, but there is only two PCI slots - both taken up by sata cards. will have to shell out some cash in order to utilize the PCI-e slots (although if memory serves this board didnt like certain combinations of PCI-e cards). thx for the feedback guys - will report back on memtest / testing on RC3

cant find a link with more details - but the MB is a XFX NFORCE 680I SLI INTEL SOCKET 775 DDR2 - running a Q6600, and them some additional 4 port promise sata cards. ifconfig seems that it will be more use when i actually copy some data to it again? root@Storage:~# ifconfig eth0 Link encap:Ethernet HWaddr 00:04:4b:06:0e:1a inet addr:192.168.0.4 Bcast:192.168.0.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:21205 errors:0 dropped:0 overruns:0 frame:0 TX packets:19970 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1987411 (1.8 MiB) TX bytes:28792554 (27.4 MiB) Interrupt:41 Base address:0xc000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:130 errors:0 dropped:0 overruns:0 frame:0 TX packets:130 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:27106 (26.4 KiB) TX bytes:27106 (26.4 KiB) ethtool capture follows root@Storage:~# ethtool eth0 Settings for eth0: Supported ports: [ MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: MII PHYAD: 1 Transceiver: external Auto-negotiation: on Supports Wake-on: g Wake-on: g Link detected: yes root@Storage:~#

Hi guys i am really banging my head here ( read going bold at an alarming rate ) long story short - i am a complete newbie on unraid - so the learning curve is a bit steep. I am having an issue where data copied over to the unraid share have quite a high chance of corrupting, and i am not entirely sure as to why this is happening ie - i did this a few times already - where i setup an unraid with a certain amount of disks, build it with parity, and then copy a certain amount (>1TB) of test series to it over a SMB network (from windows 7 machine towards unraid) after this i use a software called winmerge to verify if all the files is copied successfully - and every time so far, it encountered files that is corrupted completely ( ie when i open the video via a media player - the original file opens without any problems, but the new-copy fails to open at all - complete file corruption the last attempt i went the preclear route ( which took over 24 hours for all the drives), and then i opted to re-create the array using only disks which didn't report any "new" failing smart parameters (one drive was showing errors - i will try and have it replaced soon - i then went ahead and copied about 1.7TB of files over, noticing that the copying speed was not going at a constant rate (ie jumping between 40/50MBpss, and then dropping to below 10MBps in some cases (so much so that copying the data took another day..... ). I even tried this with a new array without a parity drive -(expecting a more cosntant speed since parity calculations/writes wasnt supposed to happen - still the same network performance. problem is - once again verifying the data showed me that about 16GB of files didn't survive the process. Corrupted files is spread accross multiple disks - which leads me to believe its either a network issue or something else went wrong. i did broke the rules a bit - i am running a beta with some addons ( simplefeatures and Unmenu with some basic packages). i am completely willing to start form a clean slate (even if possible -use a secondary onboard lan-interface if this proves to be the culprit). I am using user shares with a split level of three (resulting in a season of shows to be stored per disk) i plan to start using the unraid server sometime soon for backing up data ( or probably even better - use it to store latest data and my old-rig as a backup - still deciding on that) , so resolving this issue is rather important can anybody recommend where i need to start looking to find the cause of the issue? - any ideas is welcome -as i am running out of ideas Thx Neo_x Syslog : http://pastebin.com/nVMmF1nN unraid version : 5.0-beta14 2012/05/28 Solved - turns out some files on my source server had a incorrect modified date 2098/01/01 (which got further damaged .modified after copying it to unraid / Linux), causing me to be unable to open them with VLC media player. corrected it with an application called touch (adjusting modified date/time) obtained from http://www.stevemiller.net/downloads/ctb10w32.zip

Does your hardware support S3 sleep mode ? You can easily test this by pressing the "sleep" button on the main page, this brings the system immediately to sleep. yup that is working wonderfully. Also managed to test the next step (Wake On Lan). thus next step is to automate it i am quite sure that nothing is accessing the RAID ( the drives spinning down is proof of this i guess). Only have one network drive mapped in windows towards the user share, which as far as i know will only generate activity if its opened.

Hey guys hope somebody can point me in the right direction i am trying to get SimpleFeatures to assist me in putting my Unraid box to an S3 sleep after 20 minutes of inactivity. drives have been set to spindown after 15min, and the following settings have been set under the SimpleManament options (usign SimpleFeatures 1.0b7 on Unraid 5.0-beta14) S3 sleep function enabled waot for array inactivity : yes extra delay : 5 interval of network /device inactivity 5 Ethernet interface : eth0 wait for network inactivity : no rest of the settings was left on default ( except for forcing gigabit speed on wake-up), and set WOl settings= g Syslog : http://pastebin.com/VkjV2zdY The three drives did spin down after 15minutes ( parity + 2 active), so i am not sure what else is blocking Thx for assisting Neo_x

maybe test teh flash on another pc to rule out the flash being the problem? otherwise - i had some boards giving me a bit of crap - solution was to go into the hard drive boot priority and select the flash from there ( ie power on pc with flash already connected, go into bios, boot settings, set HDD as primary, and then inside the hard drive list make the flash the highest priority.

This is the strange part - the settings is already enabled - which leads me to believe something is not working as it should? I will try and implement the sleep and spin-down functionality - but a complete power down will be preferred if at all possible

Hey guys firstly - must say that all the responses on this forum generally says how much trust the people place in Unraid - and that normally wins the product for me. I decided to dip my toes into the unraid environment (especially having a mdadm array giving up on me yesterday- losing about 3.5TB of HD movies ) so basically - i installed the latest beta Unraid - Version - unRAID Server Basic version: 5.0-beta14 Running on a Q6600 system, 4GB ram, and +- 9x1TB hard drives already connected(a;tho i am going to use only three - i plan to grow the unraid in the near future) - onto a flash drive, and booted up the system. I then added three drives (1TB seagate's), and configured usershares as per the detailed guides provided(Saved alot of time - THX GUYS ). Parity generation was then allowed to complete, and i gave it a secondary check after it was generated in order to be sure. My next step in testing - controlling the powerdown and power-on for the system Issue is - even if i use a clean power down via the HTTP interface, and then powering up the system manually via power button - the RAID doesn't start up automatically RAID-Status after boot-up reports : Stopped. Configuration valid. Syslog capture http://pastebin.com/MMFBdvpJ clicking on the raid start button does bring up the array, but i would like to automate this (since this is going to run in the back ground allowing a MEdia center to retrieve data when needed) Is this a design feature (probable safety guard against drive failure)? Not sure if i missed a configuration setting somewhere - so any assistance will be greatly appreciated (Under disk settings enable auto start is set to yes - cant find any other setting to allow the RAID to start) Next question, while i am here Flash disc's does fail sometimes . yes i know - probably not soon - but is there a way to backup configs and register with a new flash? (yes i know - the licensing is all based on this - but i don't want to be stuck) - and secondly - does replacing the flash affect the chances of recovering/starting the raid? - it seems if i create and start the raid as per original order(via serial number), then it should be safe? Is there a way to improve the boot-up time of the unraid system? ( except for allowing it to go to sleep in stead of complete shutdown) (the unraid share is going to be utilized to store movies/series which is not accesed often, so to safe power it will mostly be powered down completely in order to safe power and drive-life. This should be all for now - thanx for helping Neo_x ** Edit Solved - Changed and applied the Auto-start functionality to No, saved/applied, and then back to yes. Seems to be fine now.

Hi there guys I am also very interested in getting unraid to work on virtual machine. as mentioned by previous posters i am currently stuck on the 4 x IDE limitation, with unraid not detecting drives simulated as SCSI. i am unfortunately a linux noob of note.. , so getting vmware to run on unraid seems a bit tricky, and on top of that i will lose possible functionality on the virtual windows (i still want to play the odd windows game on the pc when my friends come over for a visit.). I have tried (and failed) with other virtual solutions, where virtualbox allowed unraid to detect the drivers, but failed to simulate the USB(which means registering/upgrading to pro will be impossible). Anybody out there willing to assist(*hint paypal *)? Unraid seems to be the best solution out there(after failing a bit using windows SW RAID). Thx Neo
