RE: [hobbit] Disk Usage problems

["Manocchia, Robert" <Robert-Manocchia (at) IDEXX.com>]

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.

Subject: [hobbit] Disk Usage problems

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/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/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/sda3              24G  2.8G   20G  13% /export/home

172.31.129.166:/dev/tr/5s   39G  876M   38G   3% /sys2

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
