Segfault/Kernel panic and now some files are input/output error: xfs_repair doesn't work

[spamalam]

I've been having some fun, I have several SSDs and recently found that several files have input/output error when read.  I have tried xfs_repair but the files aren't moved / dealt with.

 

I've rebooted with the array stopped (since this concerns cache only),  and mounted the disk:

root@xxx-xxx:/path/Games.1952.1080p.BluRay.Remux.AVC.FLAC.2.0-HiFi# mv Games.1952.BluRay.Remux.1080p.AVC.FLAC.2.0-HiFi.mkv  /mnt/downloads/completes/sabnzbd/movies/completes/Games.1952.1080p.BluRay.Remux.AVC.FLAC.2.0-HiFi/
mv: error reading 'Games.1952.BluRay.Remux.1080p.AVC.FLAC.2.0-HiFi.mkv': Input/output error

I feel like really there's a bad block and these files need to be hidden/removed (the disk is an SSD), but I was expecting xfs_repair /dev/sdd1 to take care of that ¯\_(ツ)_/¯

Cache is reporting media errors, xfs_repair won't work on a failing device, best bet is to clone the device to a new one with ddrescue then use xfs_repair on it.
