Phoenix Down

Not sure; I did not run into this issues for any of my 8 disks. Maybe there's a hint in this thread:

Just trying to eliminate variables, see if it’s an issue with your large disk or something else.

What happens if you tried a different disk first?

Have you encrypted any other disks in your system? Were they successful?

Check the system logs (top right, left of the solid circle with a question mark). That sounds like the format was unsuccessful for some reason.

See my reply above: Did you start the array back up after you changed the disk type to "XFS Encrypted"?

Check to make sure you copy and pasted the correct checksums into the RAM disk script. Maybe you missed a digit at the end.

If your Unraid version is different than @Mainfrezzer's code example, then it's possible those files are also different. So yes, you should update the RAM DIsk code with your own checksums. Note that doing this doesn't mean the RAM Disk code won't have any issues, just that the code won't abort itself. It might or might not have any issues, but we don't know until someone tries it out whenever a few version of Unraid comes out.

If you look at this line: echo -e "45361157ef841f9a32a984b056da0564 /etc/rc.d/rc.docker\n9f0269a6ca4cf551ef7125b85d7fd4e0 /usr/local/emhttp/plugins/dynamix/scripts/monitor" | md5sum --check --status && compatible=1 There are two files in the format of "md5_checksum path_to_file": 45361157ef841f9a32a984b056da0564 /etc/rc.d/rc.docker 9f0269a6ca4cf551ef7125b85d7fd4e0 /usr/local/emhttp/plugins/dynamix/scripts/monitor You can use md5sum to generate new checksums on those two files, like: md5sum /etc/rc.d/rc.docker Sounds like @Mainfrezzer's code already includes the new checksums for 6.12.4. But you can double check yourself if you want.

I'm holding out for RAM Disk compatibility before upgrading to 6.12.

Just wanted to say thank you @mgutt! I had an earlier version of your RAM Disk installed. Wasn't even sure of the version, as it didn't have the version number in the comments. Must have been from a couple of years ago. In any case, after upgrading to 6.11 recently, I noticed that my Disk 1 would have writes to it frequently, which wakes it up along with my two parity disks. This is despite me emptying all contents from Disk 1, and all of my Dockers running from the SSD cache pool. Also, new writes should have gone to the cache pool and not the array. I spent hours watching iotop and dstat, and I was about to pull my hair out when I noticed that Disk 1 would only wake up when certain Docker container is running (specifically DiskSpeed and HomeAssistant). On a whim, I looked to see if there is a newer version of the RAM Disk available, and found this thread. I updated the RAM Disk code, and viola! No more disks waking up! Still not sure why certain Dockers are writing directly to the array or why it's always Disk 1, but I'm glad the new code fixed the issue

Awesome, thanks Jorge! Can I assume that this option is enabled by default? When did this option get enabled in Unraid? I found some posts as early as 2-3 years ago that still said TRIM is not supported on encrypted SSDs on Unraid.

Does anyone know what's the latest on this? In theory it is possible to enable TRIM on LUKS encrypted SSDs, but is it enabled on Unraid? https://www.guyrutenberg.com/2021/11/23/enable-trim-on-external-luks-encrypted-drive/

Understood, thanks for the reminder 🙂 Turns out it's a bit easier than the video. Once you've emptied a drive using Unbalance, you just have to stop the array, and then change the disk type of the disk you just emptied to "XFS Encrypted", then start the array back up. Lastly, format the disk and that disk is converted.

Is this 5 year old guide from SpaceInvader One still the best method to encrypt an existing array?
