I had to hard reboot to clear that issue, and I decided to do another 'btrfs check' while /home was unmounted. It generated the following output: checking extents checking free space cache Wanted bytes 45056, found 32768 for off 63805808640 Wanted bytes 111190016, found 32768 for off 63805808640 cache appears valid but isnt 62843256832 Checking filesystem on //dev/mapper/home UUID: 9a60a25f-eeb4-494c-b1af-ebd8e4f79b6b found 13672418478 bytes used err is -22 total csum bytes: 72089212 total tree bytes: 906100736 total fs tree bytes: 808370176 total extent tree bytes: 18153472 btree space waste bytes: 116247440 file data blocks allocated: 101046853632 referenced 73680674816 Btrfs v3.14.1 This is on the new filesystem. I redid the dmcrypt and the lvm lv when I recreated the filesystem as well, so it's less than a week old. Before rebuilding the old was was telling me: Checking filesystem on /dev/mapper/home UUID: 4f5d7a10-d003-48a7-a901-bf22d534888f free space inode generation (0) did not match free space cache generation (115200) found 29963117667 bytes used err is 1 total csum bytes: 63740440 total tree bytes: 745504768 total fs tree bytes: 624951296 total extent tree bytes: 36749312 btree space waste bytes: 119018687 file data blocks allocated: 181026942976 referenced 73759866880 Btrfs v0.20-rc1-358-g194aa4a-dirty and checking extents checking free space cache checking fs roots root 257 inode 29647 errors 200, dir isize wrong root 257 inode 391917 errors 200, dir isize wrong root 257 inode 497392 errors 410, odd dir item, nbytes wrong Checking filesystem on /dev/mapper/home UUID: 4f5d7a10-d003-48a7-a901-bf22d534888f free space inode generation (0) did not match free space cache generation (115200) found 31310902624 bytes used err is 1 total csum bytes: 63579480 total tree bytes: 743342080 total fs tree bytes: 623198208 total extent tree bytes: 36601856 btree space waste bytes: 118906643 file data blocks allocated: 180831965184 referenced 73631731712 Btrfs v3.14 -- 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
