I 'just' noticed that at some point, my USB backup drive on my server is mounted as read-only and all of my background sync cron jobs have been failing.
So I need to fix this without rebooting the server.
I can VNC into the server and running "mount" shows:
/dev/sdc1 on /media/HD103SI type ext4 (rw,nosuid,nodev,uhelper=udisks)
and umount gets:
# umount /dev/sdc1 umount: /media/HD103SI: device is busy. (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1))
How can I get this drive r/w?
