I'm not familiar with QNAP but there's nothing for it in fstab, so I |
| 113 |
presume running the relevant app on your end magically mounts the remote |
| 114 |
share without consulting fstab? |
| 115 |
|
| 116 |
It all looks very much like your init system is simply not umounting the |
| 117 |
shares at all so when it tries to remount / ro near the end, this fails. |
| 118 |
|
| 119 |
The simplest way around this is to add nfsmount to the default runlevel. |
| 120 |
This will work today as it reads /etc/fstab at startup to mount stuff |
| 121 |
and your fstab has no nfs shares in it. |
| 122 |
It reads /etc/mtab at shutdown to umount stuff and your QNAP share will |
| 123 |
be in that file. |
| 124 |
|
| 125 |
I simulated it here and that's the result I got. But this is gentoo, and |
| 126 |
everything might change tomorrow so YMMV :-) |
| 127 |
|
| 128 |
You could also write a scriptlet to do the umount and put it in |
| 129 |
/etc/conf.d/local - see /etc/init.d/local for details |
