Right on the first day of use, I received error messages at boot time like these: BTRFS error (device dm-0): block group 11840520192 has wrong amount of free space BTRFS error (device dm-0): failed to load free space cache for block group 11840520192 Then I added the clear_cache option to see if the problem would go away. After 3 boots, it did go away. But after some more boots, it's back! I believe there has been no unclean shutdowns nor lock-ups so far. What could be causing this error during normal operation? I have: Kernel 3.12.9 btrfs-progs 3.12 /etc/fstab: # /dev/mapper/luks-pool UUID=c56031b3-af27-41f6-8103-ede1f0743ac0 / btrfs subvol=arch,compress=zlib,nospace_cache,rw,noatime,clear_cache 0 0 # /dev/mapper/luks-pool UUID=c56031b3-af27-41f6-8103-ede1f0743ac0 /var btrfs subvol=arch-var,compress=lzo,nospace_cache,commit=180,rw,noatime,clear_cache 0 0 # /dev/mapper/luks-pool UUID=c56031b3-af27-41f6-8103-ede1f0743ac0 /home btrfs subvol=home,compress=zlib,nospace_cache,rw,noatime,clear_cache 0 0 Thanks!
