Hi,
I've encountered with this problem (failed to remount / to read-only on shutdown) when playing with zfs (standalone, not rootfs on zfs).
I'm pretty sure that issue caused by zfs module (version 0.6.2-r3) because I'm able to remount root read-only without zfs:
| Code: |
# rc single
<...>
# mount -o remount,ro /
mount: /: filesystem mounted, but mount(8) failed: Read-only file system
# mount -o remount,rw /
# modprobe zfs
# mount -o remount,ro /
mount: / is busy
|
zfs kernel module is unloadable I suppose. Can anybody help me here? Ideas? |

Sorry, It was my fault. For testing I've used storage located at file in root filesystem -- so I got lock.
But how can I tell zfs that file should be released because system is going to halt? |
