That definitely looks like a bad mounted disk. It's multiple sectors that are not reading at all. It's best to start pulling data from backup.

Some days before we had such a problem , the best thing to do is to stop the server and make clone of this HDD to another HDD.But there can be some corrupted files.

Hardware is in the process of dying. PRobably a good idea to replace it / sync the data / restore from backups

The harddisk has certainly having a problem. Try to recover the data and move it to another hard disk first.
