Thank you, I upgraded to the Arch package for 3.15.0-1-mainline (it's rc4) and I'll let you know if the errors reoccur. Should the filesystem be rebuilt again? A 'btrfs check' of it returned: checking extents checking free space cache checking fs roots checking csums checking root refs Checking filesystem on /dev/mapper/home UUID: 9a60a25f-eeb4-494c-b1af-ebd8e4f79b6b free space inode generation (0) did not match free space cache generation (6409) free space inode generation (0) did not match free space cache generation (6397) found 41686685877 bytes used err is 0 total csum bytes: 74074632 total tree bytes: 907673600 total fs tree bytes: 807567360 total extent tree bytes: 18251776 btree space waste bytes: 116552179 file data blocks allocated: 112191107072 referenced 75535110144 Btrfs v3.14.1 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
