Hello,
I currently have an existing pool on ZFS storage appliance that is already in use and has a bunch of virtual machines. The virtual machines are running very slow so I have researched some tips and want to try to change some settings to see the impact. As described here:
https://docs.oracle.com/cd/E19253-01/819-5461/ghbxt/index.html
Currently the pool is set to cache all data and metadata and no compression algorithm is used.
My question is if I change these settings to metadata and compression, will this have a risk of losing my data and crashing of a currently running system. My guess that it will, but maybe I am wrong.
So I will be glad to hear from you how safe this is because I have no test pools to use.
