Hi I can't mount my boot partition anymore. When I try it by entering "mount /dev/sdi1 /mnt/boot/" I get: > mount: wrong fs type, bad option, bad superblock on /dev/sdi1, > missing codepage or helper program, or other error > > In some cases useful info is found in syslog - try > dmesg | tail or so.
"dmesg | tail" gives me: > BTRFS info (device sdi1): using free space tree > BTRFS info (device sdi1): has skinny extents > BTRFS error (device sdi1): cannot mount read-write because of unsupported > optional features (2) > BTRFS: open_ctree failed I am using an Ubuntu 16.10 Live CD with Kernel 4.8 and btrfs-progs v4.8.2. "btrfs inspect-internal dump-super /dev/sdi1" gives me the following: > superblock: bytenr=65536, device=/dev/sdi1 > --------------------------------------------------------- > csum_type 0 (crc32c) > csum_size 4 > csum 0x0f346b08 [match] > bytenr 65536 > flags 0x1 > ( WRITTEN ) > magic _BHRfS_M [match] > fsid 67ac5740-1ced-4d59-8999-03bb3195ec49 > label t-hyper-boot > generation 64 > root 20971520 > sys_array_size 129 > chunk_root_generation 43 > root_level 1 > chunk_root 12587008 > chunk_root_level 0 > log_root 0 > log_root_transid 0 > log_root_level 0 > total_bytes 2147483648 > bytes_used 102813696 > sectorsize 4096 > nodesize 4096 > leafsize 4096 > stripesize 4096 > root_dir 6 > num_devices 1 > compat_flags 0x0 > compat_ro_flags 0x3 > incompat_flags 0x34d > ( MIXED_BACKREF | > MIXED_GROUPS | > COMPRESS_LZO | > EXTENDED_IREF | > SKINNY_METADATA | > NO_HOLES ) > cache_generation 53 > uuid_tree_generation 64 > dev_item.uuid 273d5800-add1-45bb-8a11-ecd6d8c1503e > dev_item.fsid 67ac5740-1ced-4d59-8999-03bb3195ec49 [match] > dev_item.type 0 > dev_item.total_bytes 2147483648 > dev_item.bytes_used 667680768 > dev_item.io_align 4096 > dev_item.io_width 4096 > dev_item.sector_size 4096 > dev_item.devid 1 > dev_item.dev_group 0 > dev_item.seek_speed 0 > dev_item.bandwidth 0 > dev_item.generation 0 Does anyone have an idea why I can't mount it anymore?
