Hello, since kernel 4.5.0 I'm unable to mount f2fs filesystems with costom section sizes.
I use 1 GiB section sizes (for smr-hdds). A filesystem created with the command: > mkfs.f2fs -l test2 -o 0 -a 0 -s 9 /dev/sdj fails to mount in kernel 4.5.0 with the following dmesg output (3TB hdd): > [ 263.898973] F2FS-fs (sdj): Wrong MAIN_AREA boundary, start(1502208) > end(732566528) blocks(731063808) > [ 263.898977] F2FS-fs (sdj): Can't find valid F2FS filesystem in 1th > superblock > [ 263.899142] F2FS-fs (sdj): Wrong MAIN_AREA boundary, start(1502208) > end(732566528) blocks(731063808) > [ 263.899144] F2FS-fs (sdj): Can't find valid F2FS filesystem in 2th > superblock > [ 263.899148] F2FS-fs (sdj): Wrong MAIN_AREA boundary, start(1502208) > end(732566528) blocks(731063808) > [ 263.899150] F2FS-fs (sdj): Can't find valid F2FS filesystem in 1th > superblock > [ 263.899152] F2FS-fs (sdj): Wrong MAIN_AREA boundary, start(1502208) > end(732566528) blocks(731063808) > [ 263.899154] F2FS-fs (sdj): Can't find valid F2FS filesystem in 2th > superblock It makes no difference whether the fs is created using kernel 4.5.0 or earlier kernels (f2fs-tools are version 1.6.0 from gentoo stable, I tested kernels 4.1.19, 4.3.3 and 4.4.6). Using the command: > mkfs.f2fs -l test2 -o 0 -a 0 /dev/sdj instead (without the '-s 9' parameter), the fs is mountable with kernel 4.5.0 without any issues. (The other parameters make no difference - i.e. 'mkfs.f2fs /dev/sdj' is fine for kernel 4.5.0, 'mkfs.f2fs -s 9 /dev/sdj' is not. Different custom sections sizes don't seem to make a difference.) Is there a real problem with the fs or are the newly introduced checks in kernel 4.5 simply buggy? --- Matthias ------------------------------------------------------------------------------ Transform Data into Opportunity.
