Package: btrfs-tools
Version: 0.19-8
Severity: important
Hi,
I migrated from ext4 to btrfs using btrfs-convert. If I check the size of each
partitions using df -h or btrfs-show,
both of them give me wrong size of one of migrated partitions as shown below:
btrfs-show:
---------------------------------------------------------------------------------
Label: none uuid: 08f9f21a-92b9-4fa8-936b-35f10a649d5e
Total devices 1 FS bytes used 1.39GB
devid 1 size 1.00GB used 1.00GB path
/dev/mapper/linux_lvm-debian_home
Btrfs Btrfs v0.19
---------------------------------------------------------------------------------
df -h:
---------------------------------------------------------------------------------
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/linux_lvm-debian_home
1.0G -64Z -428M 100% /home
---------------------------------------------------------------------------------
fsck.btrfs -f /dev/mapper/linux_lvm-debian_home :
---------------------------------------------------------------------------------

file data blocks allocated: 1356222464
referenced 1311866880
Btrfs Btrfs v0.19
---------------------------------------------------------------------------------
As you can see, no correct info about partition size are given. Because even if
it is a partition with
no space left, I am able to write there some files in total size of more than
few tens of MB without any message
talking about no space left on device or something like that.
Have a look below:
---------------------------------------------------------------------------------
p...@debian:~$ du -h tublatanka/
28M tublatanka/
p...@debian:~$ cp tublatanka/ ./test -r
p...@debian:~$ du -h tublatanka/ test/
28M tublatanka/
28M test/
---------------------------------------------------------------------------------
If more info would be needed, just ask, i'll be watching this bug.
Thank you very much.
