<![CDATA[Rc.conf_mount_rw periodic failures in logs]]>Since upgrading from 2.2.1 up to 2.2.4 I have noticed a recurring error message in the system logs.  This happens periodically on the hour.  The only thing I can think that might be switching to RW is the job that backups DHCP and RRD data.

messages look like:
php: rc.conf_mount_rw: The command '/sbin/mount -u -w -o sync,noatime /cf' returned exit code '1', the output was 'mount: /dev/ufs/cf: Device busy

sometimes (but not always, seems to be about 1/3rd of the time) it is immediately followed by:
php: rc.conf_mount_rw: File system is dirty. Launching FSCK for /

Is this something to be concerned about?  Any way to get more data on what's going on?

I ran /etc/rc.conf_mount_rw via SSH - it returned successfully very fast.

I then ran /etc/rc.conf_mount_ro - it took a few seconds, then also completed successfully (both commands verified by looking at the output from "mount")

After the filesystem was mounted read only - I ran fsck -y /cf - and it produced the following result:

** /dev/ufs/cf
** Last Mounted on /cf
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups

When it's in ro mode (/etc/rc.conf_mount_ro) you can run "fsck -y /cf" to see if it can find/repair any errors.

It could be that the disk is starting to give out.
