[Bug] btrfs-progs v4.3.1, mkfs.btrfs manpage, profiles table missing raid1
As in the title... The btrfs-progs v4.3.1 mkfs.btrfs manpage has a quite nice profiles table listing the various profiles, single/dup/raid0/raid10/raid5/raid6. It's missing raid1. =:^( Also, it calls raid5/6 "copies" rather than "parity". Perhaps add another column for parity, change the redundancy column to copies, and adjust accordingly? Alternatively, keep the single redundancy column and just change raid5 to 1 parity and raid6 to 2 parity. Other than that, I really like the nice profiles table layout. Kudos to whoever set that up. =:^) -- Duncan - List replies preferred. No HTML msgs. "Every nonfree program has a lord, a master -- and if you use the program, he is your master."
