My norco 4224 started having high temps on parity checks this summer when my basement was 85 degrees due to mining gear. I bought the 120mm adapter and bought 3 delta fans that move 240 cfm EACH. Crazy loud, but keeps it cool and its in the basement like yours. They were the most powerful reasonably available 120mm fans I could find. Im not kidding they are very loud. At 35 watts a piece dont even think about plugging into your motherboard. http://www.newegg.com/Product/Product.aspx?Item=35-213-001 Sent from my VS990 using Tapatalk

I just found a setting in Plex "allow media deletion" and turned it off. I know I have never deleted anything and I don't know that remote users would have been able to utilize that feature. It's just strange that it has always been the MKV file missing and never the BDMV. The only connection I can make is Plex. Plex has access to the MKV share but not the BDMV share....

Yes I'm sorry. I know this is an extremely open ended question. And I cannot even tell you when the files disappeared. I could have been months ago when I did a file system conversion but I did all the steps exactly as specified including rsync or whatever the commands were. I can tell you this is going to light a fire under my behind to do more regular backups. Diagnostics folder attached. Sorry I didn't attach it earlier. tower-diagnostics-20170910-2227.zip

Ok I didn't post about this the first time. Now I am getting worried. I have my really important stuff backed up in other locations as far as pictures but I haven't been as diligent about it as I should. I will now. I have roughly 400 MKV files on my server and the same number of BDMV folders. I have had numerous occurrences of MKV files disappearing. I don't know when or how but it's gone. I don't mean just 1 movie, I mean several. Movies I am 1000% sure I had as MKVs because I have watched them via Plex. The original BDMV folder is still in the other share, but my MKV share is missing the movie. What scenarios could explain this? Data corruption? Plex does not have the ability of removing the file does it? I feel like I am being a real idiot here..... Any help appreciated.

Is t here a written procedure on doing xfs conversion using some of the newer features of UnBalance? I did a a while back with midnight commander following a sticky post and with dual parity and a noob like me it was nerve racking. I have 3 disks left that are not XFS and have been kind of bidding my time hoping a more "click friendly / noob friendly" procedure would arise.

Thank you. Started it now.

Yes. There is a little more to the story that may be relevant. I unassigned Parity2 because I was going to perform a Reiserfs to XFS conversion. Then remembered I wanted to swap my Parity 1 drive first and use the old parity 1 drive as the new conversion disk. So then I re-assigned the original parity 2 drive, performed new config, and checked "parity is valid". Nothing changed. I literally unassigned and reassigned the same disk it did not even change physical slots. I believe I then performed a parity check "no corrections" and all was valid. After all that is when I started the parity drive swap.

Hi guys. I know this is a newb post but I have no problem swallowing my pride and asking for help. I was performing a drive swap procedure on Parity 1 with a different 8TB drive. I performed a parity rebuild on the "new" Parity 1 drive and it showed successful. For good measure I decided to perform a parity check with "do not write corrections to parity". This completed but showed 148 errors. I have never in my history of UnRaid had errors during or after Parity check. What would your recommendation be? I thought about rebooting the server re-seating the drives, and performing a check again but allowing it to write corrections to Parity. How do I know the errors are with the Parity? I am attaching the diagnostic log and I do still have the original Parity 1 drive and have not pre-cleared it yet. There was nothing wrong with it. Any an all help is much appreciated. Thanks, Andrew tower-diagnostics-20170705-1014.zip

Sorry I did not try another browser. I have never used anything other than Firefox with my UnRaid dealings. Everything works with Chrome. This seems to be an issue with Firefox as documented in this post

Updated preclear and I don't know if this is related or not but Im having issues. Unable to remove plugins (all) the check box does not appear and the "remove" button stays unselectable. At the same time I am unable to select a notification type or trigger when starting a preclear. Tried a reboot. Any advice? Thanks, Andrew

I have never used the "Erase and Clear" option. Is the erase cycle normally significantly slower? I am running this on a 8TB 7200rpm NAS drive model ST8000VN002 and I am 38 hours in on step 1. Its staying right around 50 MB/s Edit: It finished erasing after 45 hours and moved onto zeroing. Zeroing at 240 MB/s. Thanks.

I have an older rackmount and it never worked right. Even using nut. It was one of the little SMART500RT1U units. It has been replaced by a APC SmartUPS 1000. None of them I paid for. So I would never actually pay for a triplite if I wanted to use it for UnRaid

Gotcha. Thanks!

Hi, I am currently using this 16 port card LSI0024 (9201-16i) which I believe is the SAS2116 controller. I installed this thing about 1.5 years ago and just plugged it in and went to town. Its been working pretty well for me. I average about 110 MB/s parity check speeds with Dual Parity. I am just now reading about all this cross flashing / IT mode, etc. Is this something I need to do? Is it possible this will help my issue of not being able to reboot my server when my APC USB communication cable is plugged in? I have an older Smart UPS and whenever the USB cable is plugged into the Unraid server Unraid will not boot. It just sits on a blank screen with a flashing underscore. I have checked boot options on the mobo, nothing is available that isnt my flash drive or a data drive. Would IT mode help that problem? Thanks for all advice!

Yea. I almost wish I had tried a difference PCI port. Thats one thing I hadn't done yet. Tower is using a Gold certified Seasonic power supply and is plugged into a APC Smart UPS so I would hope the power quality is good. I could bring a ln o-scope home from work and tinker. But probably wont lol. I'm happy for now! No trees were harmed in the sending of this message, however, a significant number of electrons were terribly inconvenienced.

Well I'll be. Re-enabled the onboard Realtek NIC and BOOM. Saturated gigabit speed! Hard to believe the Intel Pro 1000 cards (3 of them) were my problem since they are so highly regarded. Must be some kind of compatibility issue with my motherboard / cpu? Also, zero dropped packets so far. Thanks for all that helped @garycase @johnnie.black @Frank1940 @BRiT Guess I will figure out if the stuttering issue returns with use of the Realtek if and when I purchase a newer media streamer. Since the Intel didnt actually fix that problem maybe I'll be fine.

Ok. Well after stopping the array, and enabling direct IO, and restarting to make the SMB changes take effect there are no positive changes. Results are the same. I also ran smbstatus to verify I am now using SMB2 protocol. Thanks for the ideas. Any other ideas / input? I can't believe I could be so unlucky to have a weird unexplainable issue like this. I have no dockers, no VMs, etc. This is a simple NAS.

Also, you mention the Intel NIC cards were needed because of other issues? Curious what those were. The reason I stopped using the Realtek 8111E onboard was because of a stuttering issue using my Dune when playing full quality BluRay rips. It was recommended I try an Intel NIC, the Intel NIC seemed to help, but I never did get that problem resolved (kept the intel installed). It occurred immediately after upgrading to V6. Never had an issue with V5. I would like to think my Dune is bad but I haven't been confident enough to drop $300 or more on a new network media device not even sure if it will work. We have since been using Plex which is awesome for mobility, friends, etc. I would eventually like to go back to watching my full BD rips.

Do you by chance know if changes require a reboot? I have been playing with them non stop since your post with no positive results.

Well I will tell you both PC's used in testing (a x-99 platform desktop with pretty hot hardware, and a surface pro 3) are both W10 clients so that sounds hopeful. Those 110 MB/s transfers were between the two W10 PCs. I guess I can bring my laptop home from work tomorrow to test. It's a win7 PC.

Didn't have any effect even though the setting appears to have "stuck". I will try a reboot after the parity check is complete (1.5TB left). This is all I had to do correct?

Sorry to ask such a newb question but how do you tell? I ran smbstatus via telnet and I get Samba version 4.5.7 is that it? Edit: Unter the user nobody and my IP of my desktop I am showing SMB3

Yea before reboot I was over 2 million packets dropped. From what I see on this forum it is normal for these Intel Pro 1000 NICs but these cards are pretty highly recommended. I have tried 2 single port Pro 1000s and a dual port Pro1000. All have exhibited this high packet drop. I could try another PCI slot. I will tinker with some settings. Is there anything people do to run these Intel Pro 1000 cards other than plug them in? I didnt load any drivers or anything.

No. Only the NIC which has been changed out yesterday for another NIC

Ok I think I got my PC NIC issue resolved which was caused by the testing. Don't know what screwed it up, but uninstalling it in Device Manager and rebooting seems to have fixed the problem. I am back to being able to transfer 110 MB/s to a windows PC on the same switch as the Tower. For fun I unplugged the network cable from the Tower and Laptop and switched them. No Change. Still 110MB/s to the Windows PC, and 40-50 MB/s to the UnRaid box. I am using the same test file. I really appreciate any help you guys offer. This is beyond my ability. @johnnie.black I saw an older post from you about enabling direct IO mode. When my parity check is finished I will stop the array and enable that mode. Any chance that can help? My server has always had these transfer characteristics. I always wondered why I couldn't benefit from my gigabit connection and never realized that wasn't normal. Now that I have verified I can when transferring to other machines I am REALLY wanting to fix the problem. Is there any way the AMD based motherboard can be the issues? I suppose I can try another PCI slot. I really don't want to use my 2nd PCIe slot because I will need another controller at some point. Attaching diagnostic log. Any advice is greatly appreciated. tower-diagnostics-20170402-1426.zip
