Have you done memtest? Setup Syslog Server: https://forums.unraid.net/topic/46802-faq-for-unraid-v6/?do=findComment&comment=781601 and get us the diagnostics plus whatever syslog captures before the crash. Tools - Diagnostics, attach complete diagnostics zip file to your next post.

You have posted to the support thread for running Crashplan as a docker under Unraid. Our forum is not about Mac OS, except perhaps when running that OS as a virtual machine under Unraid. Are you trying to use Unraid for anything?

They can be read on linux.

Please consider that all free support comes from your fellow users, for free. We are all just enthusiastic volunteers here. These old version are more trouble for us since we aren't running them, and they often don't provide us with as much diagnostic information to work with. It really is more trouble for people who are really just giving their time and knowledge to you for free.

See this Overview from the Wiki for more details on how parity works: https://wiki.unraid.net/UnRAID_6/Overview It also has a lot of other useful information for people getting started.

The redundancy is provided by all the data disk plus the parity disk(s). If you only have one parity, then you only have redundancy for one missing disk. Dual parity allows 2 missing disks. If you have more disks then you have more of a chance of having more failures than redundancy can recover from. And bad disks aren't the only thing to consider. Bad connections or cables (power and data), bad ports or controllers, are much more frequently the problems we help users with than actual bad disks, especially when they are first getting the kinks worked out.

I'm not going to that external site and give them my email and agree to their terms.

And if these are used disks, that is another reason to think twice. Every bit of every disk must be reliably read in order to reliably reconstruct a missing or failed disk, so it is important to only use trustworthy disks in the array.

I always recommend fewer larger drives instead of more smaller drives. Each additional drive requires another port, additional power, at some point more Unraid license, and most importantly, each additional drive is an additional point of failure. And larger drives typically perform better than smaller drives due to increased density. There's a reason there is a "cracking deal" on that.

Where did you even get a 6.5.3 to update to? That version is nearly a year and a half old. Please consider updating to a more recent version. It is more difficult for us to support these old versions.

Unraid installs to RAM fresh from the archives on flash at each boot and it runs completely in RAM. There is no way to install it to anything else. You can think of the flash as the firmware of an embedded device. Yes Anytime Unraid allows different sized disks in the array. Each disk is an independent filesystem, there is no striping.

Unraid Add Container page is just getting the fields to fill in the docker run command.

Yes. On the other hand, unlike striping in RAID, I/O is only at the speed of the single disk. In fact, writes are somewhat slower due to parity updating concurrently. Caching can help with this since cache can be SSDs and raid. Recycle Bin plugin: https://forums.unraid.net/topic/41044-recycle-bin-vfs-recycle-for-64-and-later-versions/

Unraid is not RAID. Each data disk is an independent filesystem. Redundancy for the array is provided by 1 or 2 parity drives. There is currently no provision for multiple arrays, but in addition to the array you can have multiple disks in the cache pool. And different sized disks can be used in the parity array. See this Overview from the Wiki for a better idea how it all works: https://wiki.unraid.net/UnRAID_6/Overview Each disk (independent filesytem as noted) in the parity array can be encrypted or not.
