Hi, I have here a Debian-based VM that was initially set up with a 2 GB btrfs. As the installlation of a new kernel-header failed, I updated the fs size to be 4, and later, 8 GB. However, the installation still runs into an ENOSPC error. Still I can create many (empty) files, so I am uncertain whether it really is due to lack of metadata space. The test disk image is available at http://jengelh.medozas.de/files/testing-sda8G.img.xz [1.3 GB] (uncompressed size is 8589934592, so make sure the VM''s /dev/sda is as big) Root password is: wa Command to trigger the problem after having obtained network connectivity: apt-get -f install (The locale is nb_NO, you may want to change to en_US.) == Log =# df / Filesystem 1K-blocks Used Available Use% Mounted on /dev/disk/by-uuid/4ba1fa38-d62b-4940-9825-7e6cceb7fcc8 8231936 1281480 5981032 18% / # btrfs fi df / Data: total=1.57GB, used=1.13GB System, DUP: total=8.00MB, used=4.00KB System: total=4.00MB, used=0.00 Metadata, DUP: total=512.00MB, used=48.64MB # apt-get -f install Reading package lists...
