Hi All,
I am noticing some strange numbers when replacing a disk under RAID1:
[root@array ~]# btrfs replace status -1 /export/archive/
367.2% done, 0 write errs, 0 uncorr. read errs
The filesystem is currently at 6x 6TB + 2x 5TB, replacing the first of each 5TB
with 8TB units:
[root@array ~]# btrfs fi df /export/archive/
Data, RAID1: total=20.90TiB, used=20.62TiB
System, RAID1: total=8.00MiB, used=2.91MiB

Metadata, RAID1: total=23.00GiB, used=22.13GiB
Metadata, single: total=8.00MiB, used=0.00B

Is this a problem ? And is there another way to see moved / total blocks from
the running replace job ?
Thanks,
Brett.
