I'm looking at changing my Cache Pool Raid Levels back to Raid 1 to be on the safe side.  I think the performance hit will be minimal but correct me if I'm way off.

 

Will I lose all my data if I change the raid level from 0 to 1?

 

Currently, I'm Data RAID 0, System RAID1, Metadata Raid1 on two Samsung 850 Evos

I have run mover but some files are still there if I explore the drive

I have backed up my appdata just in case

 

I will be running the following command. But wonder also if I can just run -convert=raid1

-dconvert=raid1 -mconvert=raid1

 

Thanks you

No, but always good to backup any important data in case something goes wrong.

For the next person that reads this all data saved but speeds are super slow now.
