When this happens here, it's because I accessed the drive over NFS. The NFS server sometimes |
| 22 |
keeps mount points active, and they don't show up in the output of lsof probably because the NFS |
| 23 |
server is in-kernel, so there are no processes associated with it. Restarting the NFS server |
| 24 |
allows unmounting. |
