File system check did find and apparently fix issues. Will see what happens in 6 days... Thanks!

Been running this system for years, with a few upgrades here and there. Been very stable until recently, where every 6+ days I'd notice the Docker service was no longer running. Restarting would fix the issue until another 6+ days would pass. Finally bothered to look at the diagnostics, and the crashing seems to be related to: WARNING: CPU: 0 PID: 16956 at fs/btrfs/extent-tree.c:3061 __btrfs_free_extent+0x466/0xc02 ...

I was having random reboots as well, with nothing ever in the logs (like yours). The frequency of them increased over time, but running Common Problems in troubleshooting mode appeared to extend the time between reboots. Ultimately it seems to have been my power supply (7+ yr old Corsair 550 watt) Replaced that with a new EVGA 500 watt and so far at least, the reboots have stopped.

I'm curious about this - I have a SuperMicro X8SIL-F motherboard with 2x 8G ECC REG quad rank DIMMs. There are 4 memory slots, 2 per channel. If I put the DIMMs in slot 1 Channel A and Slot 2 Channel A (blue slots), the BIOS screen shows 8 GB and UnRAID shows basically the same as what tmoran000 posted. If however I put the dimms in Slot 2 Channel A and Slot 2 Channel B, the BIOS shows 16 GB and UNRAID shows 16 GB in the "allocated" box. Of course the memory is no longer interleaved in this config, and the speed drops from 1066 to 800. But it appears I get access to all the ram. I'm wondering if the BIOS automatically enables memory sparing when 2 dimms of the same size / type are on the same channel? If so, I see no means to disable it like I do on Dell servers. As an aside, the system won't boot with only 1 DIMM, or if I populate Slot 1 Channel A and Slot 1 Channel B.

They make 15k 2.5" SAS drives, we have them in some of our Dell servers - but you're going to pay for them http://www.seagate.com/www/en-us/products/enterprise-ssd-hdd/

You need to look on the label and see if it states Advanced Format Technology. I recently purchased 2 1 TB EADS drives and they have it.

Personally, I don't run other tasks while important things like parity creation are occurring. Can Unraid do it all at the same time? Sure, but if you do hit a memory limit, or max out your PSU you chance interfering with the parity calculation. And since parity protection is a primary reason why we use Unraid - I'd let the complete before doing the preclears.

The advantage to preclearing is it allows you to perform the formatting outside of Unraid so your array remains online for that potentially extended period of time. In addition you get SMART reports on the drives which will show you whether your drive has potential problems before ever trusting your data to it.
