I quite stupidly unplugged my computer today when my foot got tangled in the power strip. On reboot, I was notified
Device: /dev/sda [SAT], 8 Offline uncorrectable sectors
Smartctl tells me the problem is at LBA 2014551336 (this is a 2TB disk).
Following the info here

I'm not able to determine what file might be sitting on this block.
tune2fs -l /dev/sda5 |grep Block Block count: 472552448 Block size: 4096 Blocks per group: 32768 [root@sds-desk-2 ~]# debugfs debugfs 1.42.3 (14-May-2012) debugfs: open /dev/sda5 debugfs: icheck 235992741 Block Inode number 235992741 8 debugfs: ncheck 8 Inode Pathname
This suggests that the problem is not in a currently extant file.
I'm now trying the suggestion of writing from /dev/zero to a file in /home while in single users mode. Given that I have 1.5TB to fill, this could take a while.
Here's the question: If I just reformat and restore /home from a recent backup, will the disk automatically deal with the sectors pending reallocation?
