I have just recently replaced two 750 GB disks with two 1 TB disks. I
used the replace command to do so, aka "btrfs replace start /dev/sdX
/dev/sdY /mountpoint". Each replacement went smoothly, with no errors
reporting. I'm positive that the source and destination drives were
identified correctly. However, when I run "btrfs filesystem show", the
output is
Label: none uuid: b2dbc0e4-94fc-4089-9221-d79d7919f8cb
Total devices 2 FS bytes used 494.23GB
devid 2 size 698.64GB used 495.03GB path /dev/sda
devid 1 size 698.64GB used 495.03GB path /dev/sdb
Btrfs v0.20-rc1
The disks show up as the 750 GB, when they are in fact 1 TB. smartctl
for each drive shows
root@Lore:/home/kyle# smartctl -i /dev/sda |grep "User Capacity"
User Capacity: 1,000,204,886,016 bytes [1.00 TB]
root@Lore:/home/kyle# smartctl -i /dev/sdb |grep "User Capacity"
User Capacity: 1,000,204,886,016 bytes [1.00 TB]
Is there any harm in this? If it is simply a superficial bug I will not
worry. Would running a balance help? As for the specifics, I'm using
Debian testing x64
Vanilla kernel 3.13.0
AMD hardware
Thanks,
