reiser4: mount -o remount,ro / causes error on reboot
Using: gentoo
kernel 2.6.17.11 with beyond patchset
reiser patch 2.6.17-3
reiser4progs 1.0.5
At the end of the gentoo shutdown script is a short function which
remounts / as ro.
sync; sync
sleep 1
.
# ${x} = /
mount -n -o remount,ro ${x} /dev/null
On reboot or after a poweroff, root does not mount properly, and after
some modules are loaded, there are segfaults when running init scripts.
The init scripts prompts for the root password for maintenance. Simply
typing exit forces an unmount of / and a reboot.
After this, everything is normal. On a normal shutdown, this error cycle
begins anew. Something has changed in the gentoo shutdown sequence as this
error is new to my system. However, gentoo does not support reiser4 as it
is experimental. I wanted to report this.
Remount is required since with the halt script running, the root cannot be
unmounted. After halt.sh, reboot -idpk is called or shutdown.

There's also one in the Gentoo startup script, which attempts to remount / ro, then remount it rw. I commented that out, because it was causing similar problems. I figure if it runs sync when it shuts down, that's good enough. Still, it's an annoying problem, I think it's a kernel oops. Namesys, what kind of information would be helpful?

I figure if it runs sync when it shuts down, that's good enough. The errors I note only occur on shutdown (halt.sh) not startup. Do you think it could be an IDE timing thing similar to what was described on another thread on this ml? What's interesting is that this problem is recent and I am trying to look back and see what system-level packages were updated recently (I just converted to the 2006.1 profile before this occured and that caused a lot of programs to recompile. A week earlier, it was gcc-4.1.1. I know base layout was updated recently). Maybe something in mount changed? The shutdown scripts look the same. Something is left unhinged somewhere. Glad I was not hallucinating! Thanks for confirming for me. Still, it's an annoying problem, I think it's a kernel oops. Namesys, what kind of information would be helpful? Yes, it's annoying and disconcerting at the same time. If it was a kernel oop then, wouldn't it have shown itself earlier?
