I didn't report sooner as I could/can move its folder (but not the file itself) where it doesn't bug me and it doesn't appear to affect anything else. (I'm currently running Linux v3.12-rc5 with post-3.12 f2fs patches applied manually.) The partition is used primarily to store source code and as cache for ccache. I don't recall ever fiddling with this file directly; it probably happened during updating its repository or deleting just that. f2fs-tools's fsck (current git 2ad1fcd800) doesn't appear to do anything and aborts after some 30 seconds with: >Info: sector size = 512 >Info: total sectors = 42106880 (in 512bytes) >[fsck_chk_node_blk: 195] block addr [0xa40ae59] > >Assertion failed! >[fsck_chk_node_blk: 195] ni.blk_addr < F2FS_RAW_SUPER(sbi)->block_count If you would like me to post further info, please tell me which; I've got no idea how to further debug this. ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
