Reformat or replace the cache drive

Hi,

i still have one reiserfs drive (Cache) and want to reformat to the btrfs. My docker and apps are exclusively on the cache drive.

The steps are:

Step 1. Stop Dockers

Settings/Docker/ and change Enable Docker to 'No'

Step 2. Stop VMs

Settings/VM Manager/ and change Enable VMs to 'No'

Step 3 - Move all folders (appdata, domains, isos and system) from the Cache drive

On my unRaid they are set as Cache only with no secondary storage set therefore I can use something like Midnight Commander to move the folders from the Cache drive to the array or somewhere else.

Step 4. After the move, validate the cache drive and make sure all folders are moved and the cache drive is empty. /**The most important step**/

ls -la /mnt/cache

Step 5. Stop the array; click on Cache disk and set the filesystem to btrsfs.

Step 6. Start Array; Check format; Click Format and wait to complete.

Step 7. Move saved folders back to the Cache drive; validate.

Step 8. Start Dockers

Settings/Docker/ and change Enable Docker to 'Yes'

Step 9. Start VMs

Settings/VM Manager/ and change Enable VMs to 'Yes'

-- DONE --

The same steps can be used to replace the Cache drive. Obviously after Step 4 a clean shut down is required to change the drives. Once the drive is changed, continue with Step 5.

Hope I documented the process right. I would appreciate is someone can validate and comment.

Regards

Bob

ps.

I am fully aware that one can use unRaid movers function to move folders out and back to the cache drive but I like to control each step manually. :-)
