We use an open source tool called hobbit to monitor file system disk usage among other things. Hobbit takes about 15 minutes to get up and running. The hobbit server is a virtual server located in the Westbrook data center.

Please let me know how we can proceed.

I have a some servers grouped together with six other servers. Say I
have "Server 1" and "Server 2" and Server 1 has the disks in a storage
array mounted via /dev like so:

Filesystem Size Used Avail Use% Mounted on /dev/sda2 7.9G 4.8G 2.7G 64% / /dev/sda1 99M 65M 30M 69% /boot /dev/sda3 24G 4.0G 19G 18% /export/home /dev/tr/17s 20G 202M 19G 2% /sys6 /dev/tr/8s 39G 749M 38G 2% /sys3 /dev/tr/11s 39G 878M 38G 3% /sys4 /dev/tr/14s 39G 886M 38G 3% /sys5 /dev/tr/5s 39G 875M 38G 3% /sys2 /dev/tr/2s 39G 837M 38G 3% /sys1 /dev/tr/23s 79G 5.0G 74G 7% /sys8 /dev/tr/20s 79G 4.7G 74G 6% /sys7 /dev/tr/17r 938G 36G 903G 4% /r6 /dev/tr/8r 1.9T 201G 1.7T 11% /r3 /dev/tr/11r 1.9T 225G 1.7T 12% /r4 /dev/tr/14r 1.9T 223G 1.7T 12% /r5 /dev/tr/2r 1.9T 199G 1.7T 11% /r1 /dev/tr/5r 1.9T 217G 1.7T 12% /r2 /dev/tr/20r 3.8T 1.4T 2.5T 36% /r7 /dev/tr/23r 3.8T 1.4T 2.5T 36% /r8

And Server 2 has what are called "vodfs" mounts which it mounts the
drive via Server 1's ip like so:

Filesystem Size Used Avail Use% Mounted on /dev/sda2 7.9G 4.6G 3.0G 61% / /dev/sda1 99M 34M 60M 37% /boot /dev/sda3 24G 2.8G 20G 13% /export/home 172.31.129.166:/dev/tr/5r 1.9T 217G 1.7T 12% /r2 172.31.129.166:/dev/tr/5s 39G 876M 38G 3% /sys2 172.31.129.166:/dev/tr/8s 39G 750M 38G 2% /sys3 172.31.129.166:/dev/tr/11s 39G 881M 38G 3% /sys4 172.31.129.166:/dev/tr/14r 1.9T 223G 1.7T 12% /r5 172.31.129.166:/dev/tr/14s 39G 887M 38G 3% /sys5 172.31.129.166:/dev/tr/11r 1.9T 225G 1.7T 12% /r4 172.31.129.166:/dev/tr/8r 1.9T 201G 1.7T 11% /r3 172.31.129.166:/dev/tr/2r 1.9T 199G 1.7T 11% /r1 172.31.129.166:/dev/tr/2s 39G 839M 38G 3% /sys1 172.31.129.166:/dev/tr/23r 3.8T 1.4T 2.5T 36% /r8 172.31.129.166:/dev/tr/17s 20G 202M 19G 2% /sys6 172.31.129.166:/dev/tr/23s 79G 5.0G 74G 7% /sys8 172.31.129.166:/dev/tr/17r 938G 36G 903G 4% /r6 172.31.129.166:/dev/tr/20s 79G 4.7G 74G 6% /sys7 172.31.129.166:/dev/tr/20r 3.8T 1.4T 2.5T 36% /r7

Now i need to have both servers monitoring the disk space because
Server 2 is a backup to Server 1 and vice versa. So if I loose Server
1 then Server 2 automatically mounts the arrays as a /dev and not with
the ip.

My problem is that Server two is showing this:

red /r2 (172% used) has reached the PANIC level (95%) red /sys2 (172% used) has reached the PANIC level (95%) red /sys3 (172% used) has reached the PANIC level (95%) red /sys4 (172% used) has reached the PANIC level (95%) red /r5 (172% used) has reached the PANIC level (95%) red /sys5 (172% used) has reached the PANIC level (95%) red /r4 (172% used) has reached the PANIC level (95%) red /r3 (172% used) has reached the PANIC level (95%) red /r1 (172% used) has reached the PANIC level (95%) red /sys1 (172% used) has reached the PANIC level (95%) red /r8 (172% used) has reached the PANIC level (95%) red /sys6 (172% used) has reached the PANIC level (95%) red /sys8 (172% used) has reached the PANIC level (95%) red /r6 (172% used) has reached the PANIC level (95%) red /sys7 (172% used) has reached the PANIC level (95%) red /r7 (172% used) has reached the PANIC level (95%)

But as you can see from what the df -h command reads out they are no
where near 100% let alone 172%. Does anyone have any suggestions?

Thanks in advance
