I have just had to completely rebuild my array. These are all brand
new SAS enterprise drives. A mix of 10 and 12TB. I copied all my data
off of the old array to a bunch of individual ext4 drives, and am in
the process of copying all of the data back on to my new array.
However now I am getting these errors in dmesg. I did a scrub and zero
errors returned.
My question is this: Exactly what commands do I run to fix this?
Thanks! I have had so many repeated issues with btrfs :(
