A while back I put in my config.php file many regular expressions to ignore disks that I didn’t want to monitor, it worked great… at least I thought it did until today when I had a colleague call me and ask me to find out why a device in our system wasn’t displaying a drive which was nearly full.
After deleting the node and then adding it back in and still having the same outcome I choose to remove the regular expressions which I’d put in the my config.php a good while back. After doing so and running a discovery on the node it showed the drive in question. Out of curiosity I went in on the backend of my database and ran a query on the storage table for the device_id & storage_descr and found that many of our devices have the same serial (See below)!! Am I missing something, what is it that I need to do to ignore only the drive on the device in question?
## My regex expression to ignore a drive
$config[‘ignore_mount_regexp’][] = “/(.)30275f30(.)/”; #gcc16accs01, 10.30.1.201, D
$config[‘ignore_mount_regexp’][] = “/(.)56eab3f0(.)/”; #gcc16accs01, 10.30.1.201, E
$config[‘ignore_mount_regexp’][] = “/(.)ce209e6b(.)/”; #gcc16accs01, 10.30.1.201, F
$config[‘ignore_mount_regexp’][] = “/(.)40040e4b(.)/”; #gcc16accs01, 10.30.1.201, G
## Some of my query results
device_id, storage_descr
