Hi all,
i have a strange issue and hope someone can point me in the right direction the cacheing is permanently disabled but the reports show capacitor status is ok, i do not know why the cache is permanently disabled or how to switch it back on, i have heard some prople say turn off the server and unplug the card from the PCIe slot or remove all disks while turned off and this should renable but i am unsure of doing this or losing data.
The current performance of the pool is very bad and i am having some major performance issues with the pool
(the pool is also almost full which we are addressing with a new fileserver but as the performance on this unit is so bad it is draging out the migration to the new file server)
