[f2fs-dev] Corrupt F2FS partition - fsck is useless
One of my phones recently decided to corrupt its /data partition. I managed to copy it to my PC before wiping the phone completely, but efforts to mount or otherwise recover data from it have proven futile. Mounting fails with dmesg showing: [433918.994391] F2FS-fs (loop0): inconsistent node block, nid:3, node_footer[nid:808791088,ino:808661560,ofs:92677510,cpver:4050480101642482739,blkaddr:757872690] [433918.995566] F2FS-fs (loop0): Failed to read root inode [433919.002420] F2FS-fs (loop0): inconsistent node block, nid:3, node_footer[nid:808791088,ino:808661560,ofs:92677510,cpver:4050480101642482739,blkaddr:757872690] [433919.003598] F2FS-fs (loop0): Failed to read root inode f2fs-tools v1.11.0's fsck crashes if I tell it to recover lost+found: (NOTE: fsck output at https://luke.dashjr.org/tmp/code/fsck.f2fs-LF.log.xz ) #0 0x9911 in memcpy (__len=18446744072369571950, __src=0x557d644c, __dest=0x7fffd2d0) at /usr/include/bits/string_fortified.h:34 #1 convert_encrypted_name ( name=name@entry=0x557d644c "3\036\021\004\035=]\035\322\037\f(\212\202&\004\"\021\226\235Ec4 [\227\266\221R1\332\331! \004\226\315\270\216\030\205\020\330\334\334\344\324sg\226\275-\317\352\352\032i\222]\326Ӌ\027^\030\226\005&\006| \333b\223\204I\323P\327\r\211K\220\306\321\064\r\271\263\064u\205\322\006g\034u]\003\002)\005! \200P\nc\024R\266\070\247\360>\342\333\330\361h$\022\203\265)\306$\264-di\316\331\346,B)\212^\211\321\032\227gdY\206M\023\256\272\346j\322<_\202\214\b! \361\241\213\370\336 {\266\267w\230M&\370\246\345¹\027\271z\375\070u\323r\354\330\061\352 9s\346\034\373\367\357'(\270\264\263E\226"..., len=-1339979666, new=new@entry=0x7fffd2d0 "3\036\021\004\035=]\035", enc_name=) at fsck.c:1132 #2 0x555639d9 in print_inode_info (sbi=0x557817e0 , node=0x557d63f0, name=1) at mount.c:183 #3 0x5556424f in print_node_info (sbi=, node_block=, verbose=) at mount.c:277 #4 0x555620c2 in dump_node (sbi=sbi@entry=0x557817e0 , nid=nid@entry=2875, force=force@entry=1) at dump.c:520 #5 0xf58f in fsck_verify (sbi=) at fsck.c:2568 #6 0x679b in do_fsck (sbi=0x557817e0 ) at main.c:569 #7 main (argc=, argv=) at main.c:726 If I tell it NOT to recover lost+found, it completes, but mounting still fails: (NOTE: fsck output https://luke.dashjr.org/tmp/code/fsck.f2fs-NO-LF.log.xz ) [434361.813196] F2FS-fs (loop0): Found nat_bits in checkpoint [434361.825628] F2FS-fs (loop0): Failed to read root inode [434361.828461] F2FS-fs (loop0): Found nat_bits in checkpoint [434361.840620] F2FS-fs (loop0): Failed to read root inode Any ideas on how to get at least some data recovered from this?

Re: [f2fs-dev] Corrupt F2FS partition - fsck is useless
Hi Luke, I think the problem here is that we don't even start to traverse and check all directories and files due to we encounter root inode sanity check failure. [ASSERT] (sanity_check_nid: 412) --> nid[0x3] footer.nid[0x30352c30] footer.ino[0x30333238] Could you dump root node info with below command: dump.f2fs -i 3 -d 1 Thanks, On 2018/8/24 12:31, Luke Dashjr wrote: > One of my phones recently decided to corrupt its /data partition.
