Chris,

The inode is NOT the same one. I tried a sqlite dump | restore operation but it didn't work...

With your journalctl -f and trying dnf history, dnf reported I/O errors but no kernel or /var/log/messages appeared to contain I/O error messages.

fc35-bash 5.1 /var/lib/dnf# sqlite3 history.sqlite 'VACUUM;'
Error: file is encrypted or is not a database

The drive is a hybrid Seagate drive:

fc35-bash 5.1 /var/lib/dnf# smartctl -i /dev/sda
smartctl 7.3 2021-03-02 r5210 [x86_64-linux-5.12.0-0.rc1.20210305git280d542f6ffa.164.fc35.x86_64] (local build)

I guess it's time to rebuild from scratch?

I wonder why dnf reported I/O errors?

You previously reported them.

That is strange. The scrub should find the same corruption. If you do:

ls -li /var/lib/dnf/history.sqlite

Is the reported inode number on the left 2239235?

What kind of drive is /dev/sda? HDD or SSD?

First, this shouldn't be necessary, therefore I'm kinda suspicious.
But it's inspecific suspicion. Maybe it is conversion.

I also don't know if this will fix the SQLite I/O errors, or make
things worse, in which case you'd lose dnf history (probably not a big
loss).

sudo -i
cd /var/lib/dnf/
sqlite3 history.sqlite 'VACUUM;'

That cleans the database. It will delete the other two files which
will reappear later once dnf starts writing to this database again.
