Woudl it make sense to add a paragraph explaining that for raid5/6,
someone should either:
1) use balance to rebuild on a new drive if one of the drives is missing
2) use btrfs device add of a new drive, then btrfs device delete of the
drive to replace, and effectively btrfs will do the same thing that
replace would
?
Nice try, I think it's good to add a note paragraph for the use cases.
I'm also wondering should the same things added to btrfs-balance(8) and
btrfs-device(8) man pages,
if added, three same paragraph will be added and the duplication
paragraph may increase the difficulty to maintain
the documentation.
So I prefer to add the explaination about RAID5/6 to btrfs-device(8) and
adds note on
btrfs-replace(8)/btrfs-balance(8) to refer to btrfs-device(8), since all
of these things are about btrfs device management.
Would you prefer the modification?
Thanks,
Qu.
Thanks,
