syncthing will not start (is another instance of Syncthing running?)

[angelv (Angel de Vicente)]

Hi, I have run syncthing in my laptop for months without issues. But now it is giving me a hard time for some reason:

$ /usr/bin/syncthing serve --no-browser --no-restart --logflags=0
[start] INFO: syncthing v1.27.1 "Gold Grasshopper" (go1.21.5 linux-amd64) syncthing@archlinux 2023-12-11 07:43:23 UTC [noupgrade]
[start] INFO: Using large-database tuning
[start] WARNING: Error opening database: read /home/angelv/.config/syncthing/index-v0.14.0.db/008013.log: input/output error (is another instance of Syncthing running?)

But as far as I can see, there is no other Syncthing instance running?

$ ps -fea | grep syncthing
angelv   2044528 1522900  0 19:32 pts/13   00:00:00 grep syncthing
$

Any idea how to debug this issue? Thanks

I/O error generally means your disk and/or file system is toast…

This is in the laptop I’m using right now. As far as I can tell no other signs of disk or file system failure. The system is working all fine.

By the way, just in case, I did a reboot of the system, and I got the same message when trying to start syncthing right after rebooting.

Not sure if this means anything to you, but the .config/syncthing/index-v0.14.0.db/LOG just says:
