Hi,
I recently moved my main system to btrfs and had to shuffle everything
around in tricky ways while migrating from LVM while maintaining at
least two copies + backup of everything. I'm using linux-4.4.3 with
btrfs-progs-4.4.1. The end result, after adding sdc and then
converting both metadata and data to RAID1 is:
fdisk -l output:
/dev/sdb1 4096 1943359487 1943355392 926.7G 83 Linux
/dev/sdb2 1943359488 1953523711 10164224 4.9G 82 Linux
swap / Solaris
and
/dev/sdc1 4096 1943359487 1943355392 926.7G Linux filesystem
/dev/sdc2 1943359488 1951748095 8388608 4G Linux swap
btrfs fi show
Label: none uuid: 2757c0b7-daf1-41a5-860b-9e4bc36417d3
Total devices 2 FS bytes used 882.28GiB
devid 1 size 926.66GiB used 886.03GiB path /dev/sdb1
devid 2 size 926.66GiB used 887.03GiB path /dev/sdc1
But this is what's troubling:
btrfs fi df /.btrfs-admin/
Data, RAID1: total=882.00GiB, used=880.87GiB
Data, single: total=1.00GiB, used=0.00B
System, RAID1: total=32.00MiB, used=160.00KiB
Metadata, RAID1: total=4.00GiB, used=1.41GiB
GlobalReserve, single: total=496.00MiB, used=0.00B
Do I still have 1.00GiB that isn't in RAID1?
Best regards,
Nicholas
