Log entries about md0

[vandermerwe]

I have a 316 and am intrigued by these log entries referring to dev/md0

total_bytes 4290772992
bytes_used 972595200

dev_item.total_bytes 4290772992
dev_item.bytes_used 4290772992

dev/md127 obviously has similar lines, bytes used in dev_item.bytes_used is greater than bytes_used.

What is the significance of the dev_item.bytes used entry in md0 and md127?

I'm not sure, but thi sseems relevant: http://marc.merlins.org/perso/btrfs/pos ... blems.html

It suggests that you might want to run balance, and see if the numbers change.

I doubt it is relevant.

However

# btrfs fi show
# btrfs fi df /

Would let you know if it is.

Also, running balance would do no harm, though it might not change anything.

I still don't understand why dev/md0 would indicate that all the space is used

All the space has been allocated but there is plenty of free space.

Ok, thanks.
