I don’t know when this happened. There was a system update a few days ago which went fine. Two days ago I wanted to download something onto one of my HDDs and got an I/O error. After investigating I found out that I no longer am the owner of any of my drives and can’t create/delete any files. Chmod/chown didn’t help. Editing the fstab file didn’t help since it had the exact same contens as when everything worked. Shuffeling exec,rw around has no effect. Mounting/unmounting didn’t do anything. Phisically removing the drives also didn’t work. Adding a completely new drive automatically set it to restricted. How the hell does soemthing like this happen? I don’t want to do a system wipe.
Filesystems may be remounted read only on error. I’d expect that to be reverted post reboot, but maybe your error was big enough for it not to? You may want to search how to perform an fsck on the affected partitions.
I touhgt the same, but connecting a new drive and getting the same “read-only file system” error is really strange. I used the other drive for qbittorrent and it worked flawlessly before the update. I haven’t come around to try any of the suggestions yet. I’ll report back tonight.
Did you disable fastboot in windows to make sure this doesn’t happen again?
Fastboot was never enabled to begin with :-/
