"Endless errors"? Are you talking about disk errors? Or are you referring to that one time long ago that it had a bug wrt a specific uncommon RAID setup? APFS

"Endless errors"? Are you talking about disk errors? Or are you referring to that one time long ago that it had a bug wrt a specific uncommon RAID setup? APFS and ZFS aren't very interesting to me honestly, because neither are, or can be, in the Linux kernel. I also don't understand why APFS is in the same conversation as ZFS and BTRFS.
