FreeNASs2a mounted as rw after upgrade
|Reported by:||jgreco||Owned by:|
I'm not /quite/ sure what happened. Upgraded from a recent nightly to 8.0.1-R. The system tried to reboot itself, hung after syncing, and after 10 minutes I killed it. It rebooted fine, upgraded its database, rebooted. Upon reboot, I had some unrelated problems (vlan/network issue, see recent ticket) so went to shell. Noticed it was /very/ slow, which is usually a hallmark of the root partition being mounted rw. I think the microSD I use may be sluggish or something.
So there are three things here.
1) The root filesystem was NOT mounted read-only, which is a majorish bug. (It did mount ro after another reboot though.) Users using the web management system to upgrade their systems might well leave the system in this state, writable base system not good.
2) The root filesystem should also be mounted "noatime". Probably always. This seems to help substantially with the lag slag.
3) It's unclear why the system is laggy when the root filesystem is mounted rw. This suggests to me that some unintended writing may be going on to the root filesystem. May be wise to investigate.
