Anyway, the suggested docs page is wrong. It has many bad commands, in example:

"gluster volume heal info failed"

this doesn't exist. The right command should be
"gluster volume <volume> heal info heal-failed

Also, the replace-brick in a replicated volumes, makes use of
"setfattr" and also ask for a directory creation/removal (step 4):

mkdir /mnt/r2/<name-of-nonexistent-dir>
rmdir /mnt/r2/<name-of-nonexistent-dir>
setfattr -n trusted.non-existent-key -v abc /mnt/r2
setfattr -x trusted.non-existent-key  /mnt/r2

i didn't this and seems to work fine.

I think that this doc page should be rewrote, there is much confusion
and unneeded steps.
