[monit] Help getting monit to mount/unmount device

[Alex Soto]

Hi There,

I'm having trouble getting the monit stop/start command to mount/ 
unmount a filesystem.  I'm wondering if anyone can see the problem  
with the following:


check device dbfs with path /dev/sdh
       group server
       start program  = "/bin/mkdir -p /data/db ; /bin/sleep 5 ; /bin/ 
mount /data/db"
       stop program  =  "/bin/umount /data/db"
       if failed uid root then unmonitor
       if failed gid disk then unmonitor
       if space usage > 80 % then alert
       if space usage > 94 % then alert
       if inode usage > 80 % then alert
       if inode usage > 94 % then alert


The behavior I see is that the /data/db directory does get created,  
but the disk is not mounted.  I put the sleep in because my initial  
attempts without it failed and I thought that possibly the mount  
command was failing because it was not seeing the mount directory due  
to a race condition.

Of course, when I run it manually everything works ok.  I know the  
environment that monit runs the command in is fairly empty, but I  
don't see what I may be missing if thats the root cause.

Thanks,
Alex
