I was following the Fedora Magazine instructions on enabling btrfs transparrent compression.
My system was a newly updated F34 Silverblue (from F33 Silverblue). After running the command to compress existing files I got some failures.
$ sudo btrfs filesystem defrag -czstd -rv / /var/home/ ... total 126655 failures
Out of 370G used space the compression got that down to 335G
On the other hand there that 1.2M failures reported
Should I be worried, could files have gotten corrupted?
