Thanks JorgeB. That solved my issue.

I opened my case to look for available ports to add a new drive. I did unplug a few cables and moved some cables around but everything reseated good. I booted and my parity drive was missing. I opened the case again and reseated those cables, now the parity drive is there but its disabled with a red x. Can anyone tell me if there is anything in the logs that might point to a solution?

Jonnie, That was my thought as well, I reverted to my Intel I5 CPU and MB setup last night and my rig has now been running for 24 hours with no issues. I'm going to return the Ryzen gear and try again in a few months. Thanks to everyone for all the support.

5 passes on MEMTEST so far no errors found. Any other suggestions?

In Progress...

Thanks for the help. Here is what I got. I don't know what to look for so hopefully you see something useful. FCPsyslog_tail.txt syslog.txt

Thanks, Frank I forgot to say I ran the MEMTEST and it was clean but I will run once more so I can take a picture of the result. I will also confirm MB/CPU Temps, I didn't think of that. I will post again tonight.

I recently changed from an Intel I5 to Ryzen 7 2700x with a MSI x470 Gaming Pro. I also added an M.2 drive for the cache. The server was up and running fine for about 10 days doing Plex server duties with some handbrake conversions not much else. This morning the Server was unresponsive. I couldn't ping it or SSH to it. After a reboot, it came up for a few minutes then crashed again. I have tried it several times with several different steps and get the same thing it comes up for a few minutes or even an hour then bang it's down again. I have C-states disabled on the MB and the newest Bios. I added rcu_nocbs=0-15 to the syslinux configuration. I tried starting it in safe mode. I tried booting it and leaving the array offline. No matter what I try it seems to do the same thing, up for a short time then down. I'm about to put the old Intel CPU and MB back but I wanted to check here first to see if anyone has any suggestions. syslog (3)

If I do a system reboot, will that cause any issues other than some split files potentially?

Thanks demonmaestro however the transfer rate continues to decline and the drive actually seems to be making ticking noises, maybe it's failing... the data is mostly TV show files that can be replaced but still its concerning. I would like to kill the unbalance process and move the files via MC. Any help would be appreciated.

Update... the speed is decreasing very slowly and is now down to 15.5MB/s. At this rate, it will take days to finish scattering.

I posted in the unbalance support topic but was hoping someone could help faster if I posted here. I am trying to scatter 2TB from one disk to a few others. I have unassigned the parity drive to speed the process but the transfer speed is still only 17MB/s it should be 4x that. I want to kill the process and troubleshoot the speed issue. My question is how does one do that. I know the GUI can't kill it but I have seen mention that it can be done via a terminal session. Can someone post step by step instructions, please? Thanks

What is the command line process to kill unbalance and rsync? I am trying to scatter 2TB from one disk to a few others.

Thanks for the quick reply.

I have two small drives that I want to upgrade to larger models. Can I replace both of them in one power down and have parity rebuild them both on reboot, or is it best to do one drive at a time, rebuild it then do the second drive on another power down? Thanks in advance for any advice.

Thanks Squid, that was it. I reformatted back to XFS changed the global share settings and I'm up and flying again. I will also look at converting all drives to XFS.

I added a new drive and after preclearing it I formatted it in XFS (not intentionally just didn't realize the new default was XFS), the rest of my disks are RFS. Anyway, I tried to include the disk in my used share and it doesn't show up as an option. The new disk is disk 6 and only disks 1-5 are available. I thought the XFS formatting might be an issue so I reformatted using RFS. Below are the settings.
