On gentoo monit cannot access the root fs after upgrading to OpenRC

[Marcus Mülbüsch]

Hello all,

I upgraded a gentoo-server to OpenRC and baselayout2. All went well.

However, monit-5.2.3 now complains about not being able to access the 
root filesystem:

"Data access error Service root_fs

Date: Tue, 17 May 2011 10:37:32 +0200
Action: alert
Host: dl360
Description: unable to read filesystem /dev/cciss/c0d0p5 state

Your faithful employee,
Monit"

Only the root filesystem is affected, all other filesystems are still 
monitored by monit.

I note that /etc/mtab has changed from:

> /dev/cciss/c0d0p5 / reiserfs rw,noatime,notail 0 0

to:

> rootfs / rootfs rw 0 0
> /dev/root / reiserfs rw,noatime,notail 0 0


and /dev/root now is a link: /dev/root -> cciss/c0d0p5

However, after changing the relevant lines in the monitrc file from:

> check device root_fs with path /dev/cciss/c0d0p5

to:

> check device root_fs with path /dev/root

the error does not go away.

I posted it on the gentoo forum but did not get a reply so far. Anyone 
here has an idea what did change? Or whether there is a suitable workaround?
