Hi Unraid community,

 

I have been using Unraid for the fast few months and I have had a 'SSD' user share with two SSDs for a while. My goal is to separate one of them from the share and then use it as a cache drive.

 

There are files in the 'SSD' share split between Drive 1 and 2. My goal is to separate Drive 1 from the share but it still has files from the 'SSD' share.

Steps that I have done so far:

- In the 'SSD' share setttings I have only included Drive 2 in the share and excluded Drive 1. The files still live in Drive 1 even after this setting(to my knowledge they don't automatically shift to Drive 2 but it's been a few days since I've done this)

 

I know that moving files manually between drives could break the share, so I have avoided that.

Now my thought for getting this done would be:

- Dump all of the files from the SSD share to another share or out of the Unraid server

- Delete my 'SSD' share

- Stop the array and then switch Disk 1 to the Cache pool

- Format Disk 2 since it's in a state of a 'broken' share.

- Start array, recreate 'SSD' share only with Disk 2

I have docker containers that read/write to the SSD share, but I don't think that will break if my above steps are taken care of because it will be the same paths that docker is pointing to. (Other than permission/ownership of dirs and files but I can always manually replicate ch perms)

 

 

I want to ask the community their thoughts since there may be another way that I am not considering within Unraid.

 

Have a look at unBALANCE plugin. That should do the trick.

SSDs in the array cannot be trimmed, and can only be written at parity speed.
