yet another pre-cache upgrade question

[daan_SVK]

hi there, 

 

I am looking for some input on an cache upgrade process. 

 

my cache drive is ruining btrfs and NetData started reporting issues with allocation. The server appears to be happy but I don't want to take any chances with attempting to repair the allocation issue so I decided to upgrade the cache drive with a cache pool. 

 

is my best option still to follow the wiki thread: 

https://wiki.unraid.net/index.php/Replace_A_Cache_Drive

 

or should I be able to replace the current drive with a pool by adding second larger ssd, establishing a mirrored pool and then replacing original with another SSD that would be identical to the second one? If so: 

 

1. can I change the filesystem on the second and third drive so I dont have?

2. is the pool going to automatically expand it self once the original drive is removed and replaced with the third (identical to the secon) 

 

 

thanks for your insight!
