Failed to bind socket: Read-only file system

After reboot no web interface access: Failed to connect to socket: No such file or directory

Failed to bind socket: Read-only file system

I break it to learn.

Thanks

I thinks I am dead in the water here. Is there a way to restore permissions?

ryecoaaron · Jul 6th 2021

When a filesystem has an issue on boot, sometimes the options will tell it to automatically re-mount readonly. It looks like yours did that. What is the output of mount?

ajaja · Jul 6th 2021

UGH!

I suspect it is UnionFS

I have no concern for the data; it is safe. I just want to understand how to get out of the penalty box.

Nope. Your root filesystem is mounted readonly. sudo mount -o remount,rw / should fix but you should really run an fsck on it. Are you using a usb stick or did you system get shutdown improperly?

I got it to work; I had to hand-build the fuse.mergerfs. I will dump a bulk of data into it and test it this weekend.

What do you mean by hand-build? Are you just constructing the fstab entry? If you just want to use different paths, you could use the mergerfsfolders plugin.
