Cache disk encryption

[reey]

Hello,

 

I've successfully encrypted my array. 

But since I've got a few shares, that stay the whole time on my cache disk I would love to be able to also encrypt it.

I didn't found an option for that, so I guess that this is not possible at the moment?

Is there a specific reason why not? Maybe performance issues?

 

I'm sorry if I overlooked something and this option is already available..

I also thought there was an option to change the filesystem of the cache drives, but didn't found that anymore.. (It says BTRFS is the default..)

This would have been the place, where I expected an option to encrypt the cache..

 

thanks

It's the same as for array disks, on the main page click on cache and change the filesystem to an encrypted one.

For the array disks I've changed the "Default file system" in Settings -> Disk Settings and there is no option to do this for the cache drives..

OK I found it, the array needs to be stoped for that..

But do I need to move the data before changing the filesystem? Or does it just encrypt the filesystem and the data stays?

 

Edit:

Data will be lost

Same as array disks, cache will need to be formatted

So now I've got my Array and my cache completly encrypted, but I don't understand, how it is possible that some folders still show up, as not encrypted.. see attached screenshot..
When I open that folder it seems like a newly created folder is unencrypted.. 

But all fIles in that folder are marked as encrypted..
The folder was created by a docker container, if that should make any difference..
