Hi everyone,
I have a btrfs filesystem ontop of a 4x1tb mdraid raid5 array and I've been getting confusing output on metadata usage. Seems that even tho both data and metadata are in single profile metadata is reporting double the space(as if it was in dupe profile) root@thebeach /h/marcg> uname -a Linux thebeach 4.6.2-gentoo-GMAN #1 SMP Sat Jun 11 22:32:27 ADT 2016 x86_64 Intel(R) Core(TM) i5-2320 CPU @ 3.00GHz GenuineIntel GNU/Linux root@thebeach /h/marcg> btrfs --version btrfs-progs v4.5.3 root@thebeach /h/marcg> btrfs fi us /media/Storage2 Overall: Device size: 2.73TiB Device allocated: 1.71TiB Device unallocated: 1.02TiB Device missing: 0.00B Used: 1.38TiB Free (estimated): 1.34TiB (min: 1.34TiB) Data ratio: 1.00 Metadata ratio: 1.00 Global reserve: 512.00MiB (used: 0.00B) Data,single: Size:1.71TiB, Used:1.38TiB /dev/mapper/storage2 1.71TiB Metadata,single: Size:3.00GiB, Used:1.53GiB /dev/mapper/storage2 3.00GiB System,single: Size:32.00MiB, Used:208.00KiB /dev/mapper/storage2 32.00MiB Unallocated: /dev/mapper/storage2 1.02TiB root@thebeach /h/marcg> btrfs fi df /media/Storage2 Data, single: total=1.71TiB, used=1.38TiB System, single: total=32.00MiB, used=208.00KiB Metadata, single: total=3.00GiB, used=1.53GiB GlobalReserve, single: total=512.00MiB, used=0.00B root@thebeach /h/marcg> I'm not sure if this is known and if it's btrfs-progs related or if it is actually allocating that space. Thank you for reading.
