Hi list,
I've got a 3-device RAID1 btrfs filesystem that started out life as
single-device.
btrfs fi df:
Data, RAID1: total=1.31TiB, used=1.07TiB
System, RAID1: total=32.00MiB, used=224.00KiB
System, DUP: total=32.00MiB, used=32.00KiB
System, single: total=4.00MiB, used=0.00
Metadata, RAID1: total=66.00GiB, used=2.97GiB
This still lists some system chunks as DUP, and not as RAID1. Does this
mean that if one device were to fail, some system chunks would be
unrecoverable? How bad would that be?
Assuming this is something that needs to be fixed, would I be able to fix
this by balancing the system chunks? Since the "force" flag is required,
does that mean that balancing system chunks is inherently risky or
unpleasant?
Thanks,
Steve
