I've tried to calculate somehow what block is on sector 50868652 and I got 6291509. Badblocks program successfully recognize this block as bad. And "dumpe2fs -b" shows it. But this block is touched again and again. And I think that means that messages "Programming error? block #?????? claimed for no reason in process_bad_block" are irrelevant to this issue. And that link I've mentioned is irrelevant too.
And I am going to attach full dumpe2fs output and "tune2fs -l". I hope it will help somehow. (The name of the disk is changed from sdb2 to sdc2 after reboot.) ** Attachment added: "tune2fs-sdc2.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1723415/+attachment/4970164/+files/tune2fs-sdc2.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1723415 Title: ext4 filesystem does not use its badblock list Status in linux package in Ubuntu: Confirmed Bug description: 1) Ubuntu 4.13.0-15.16-generic 4.13.4 2) Will be attached. Always, when I have /dev/sdb2 mounted, I get an errors in the system log, such as in the file dmesg.txt (attached)(there are i/o errors and something). Thus I ran fsck: { root@user:~# fsck.ext4 -fck /dev/sdb2 e2fsck 1.43.5 (04-Aug-2017) Checking for bad blocks (read-only test): 0.24% done, 0:25done /dev/sdb2: Updating bad block inode. Pass 1: Checking inodes, blocks, and sizes Programming error? block #230376 claimed for no reason in process_bad_block. Programming error? block #230385 claimed for no reason in process_bad_block. Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /dev/sdb2: ***** FILE SYSTEM WAS MODIFIED ***** } But the errors did not disappear and I ran "badblocks -so ./bads-sdb2.txt -b 4096 /dev/sdb2" Then I tried "fsck.ext4 -l ./bads-sdb2.txt /dev/sdb2" and it showed, among other typical things, this: { Programming error? block #230376 claimed for no reason in process_bad_block. Programming error? block #230385 claimed for no reason in process_bad_block. } Then I ran "dump2fs -b /dev/sdb2" and found that every block from bads-sdb2.txt is already included in there, but the errors keep appear. And while I was searching for a solution, I found this: https://sourceforge.net/p/e2fsprogs/bugs/187/ I think this situation can be found on Ubuntu 16.04 too.
