I have a btrfs filesystem which has plenty of free space left, yet it's hitting out of space regularly.
Here is how it looks like: # btrfs fi df /home Data, RAID1: total=2.51TiB, used=1.58TiB System, RAID1: total=32.00MiB, used=372.00KiB Metadata, RAID1: total=48.00GiB, used=47.23GiB What I read from it, is we're almost full on metadata usage, and that might be causing out of space issues. Reading past posts on this group, I can see it's recommended to run this if I hit out of space and the fs is low on metadata space: # btrfs fi balance start -dusage=5 /home Is it really the only workaround? Shouldn't the filesystem be more intelligent and be able to grab some more metadata space if it's running low? I'd appreciate some clarifications on this (FYI, it was running 3.11.4, upgraded to the latest rc now). -- Tomasz Chmielewski http://wpkg.org -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
