Something is definitely wrong with transcoding. When I playback video on my big screen connected to my Roku, I get choppiness and buffering when set to auto. It goes away when I set it to direct. However, my smartphone over wifi will only work if I select transcoding. Not sure what to make of this but it didn't happen before the last container update.

I was thinking the transcoder performance was worse. I'm getting stuttering and stalls, but when I set quality to original everything plays fine.

Frank1940, Thanks! It is now set if this happens again. I've attached the syslog from the first and only time it failed. Not sure what to make of it except I see a general protection fault (which to me usually indicates a memory leak) and an error on the SSD drive, but nothing further shows up on the SSD. Ran SMART tests and it shows fine. Dale tower-diagnostics-20190712-1413.zip

That's the problem. This has been the only time it happened so I have no basis to determine when it might happen again. If it does, I believe there is close to a zero chance that getting a Diagnostics file saved since everything appeared to be down before the reboot. There was a syslog from before and after the crash though.

I upgraded to 6.7.2 from 6.6.6 about a week ago and all seems well. Before that I replaced the Marvell SATA controllers with an LSI Broadcom SAS HBA. Disk access times are better too. I did have one anomaly. Sometime during the early morning I could not access shared from any computer on my network. The webgui was still running but show zero CPU utilization. I tried to shutdown, but all I got were the standard shutdown warnings and nothing happened. After about 45 minutes I forced it down and restarted. Everything came back up but it had to do a parity check. I've never had this happen before. Dale

Do you have any Marvell SATA controllers? I have one where two of my array disks are attached and had the same problem going from 6.6.6 to 6.7.0. I rolled back and had no problems. I'm guessing based on your experience the problem did not go away with 6.7.2.

I agree 100%. It is impossible for anyone to test for every condition and they have responded very quickly to address problems as they surfaced. unRAID OS is the best thing going!

Does 6.7.2 solve the Marvell missing disks problem?

I recently moved my Plex system to use the linuxserver.io plex docker. All seems well except occasionally I see a half second blip on screen during playback. I thought it might be related to the transcode folder, since it looks like it is going to the array. I tried to move it to tmp, but that made the problem worse, even causing some content to not play at all. I also noticed that using Plex.tv webgui it tends to skip ahead 5 seconds or so several times. Any thoughts on what is causing this? I had no problems like this running Plex under the PhaZe plugin.

Monthly parity check shows no errors! Event: unRAID Parity check Subject: Notice [TOWER] - Parity check finished (0 errors) Description: Duration: 23 hours, 49 minutes, 14 seconds. Average speed: 139.9 MB/s Importance: normal Plus that 12TB WD Gold drive has improved the elapsed time of the parity check. I've been very happy with those drives. Dale

My monthly parity check is scheduled for tomorrow so I should know before the weekend is over. Thanks!

I installed my first new drive into the array without using preclear and it went flawlessly! The new drive is a WD Datacenter Gold 12TB which replaced a WD Red 6TB. Here are the stats: Event: unRAID Parity sync / Data rebuild Subject: Notice [TOWER] - Parity sync / Data rebuild finished (0 errors) Description: Duration: 1 day, 33 minutes, 16 seconds. Average speed: 135.8 MB/s Importance: normal Much faster to be fully up and running and have a protected array than it used to be. Good job!

Thanks John_M. Are you referring to SMART diagnostics? Sent from my SM-G955U using Tapatalk

Also since it appears from the log report it completed the clear operation successfully, is there a way to verify the drive without going through preclear again? I'd like to know if the drive is usable. It just looks like preclear stopped at 18% of the post clear read.

Frank1940, did you see in my post where I already acknowledged the cable issue and replaced it? This problem of hanging on 18% on the post clear read has occurred after the cable was replaced. It seems like it might be an issue with preclear. Any known problems dealing with a drive of 12TB?

I am running into a problem with preclear on a WD Datacenter Gold 12TB drive. It made it through steps 1 through 4 and started on step 5 where it seems stuck at 18%. The drive also shows spun down. The version of Preclear is 2017.11.14. Here is the log report so far. (The 199-UDMA_CRC_Error_Count 106286 is from a previous attempt where I had a faulty cable.

Same here and running 6.0.1. No answers?
