Nagios XI installation on External Lun

[socgenindia]

Hi ,

Please let us know is that possible to install the Nagios XI on external LUN instead of default location /usr/local/ path.

It's possible, but doing so would make your system unsupported and is likely more trouble than it's worth. We also do not have specific documentation for a setup like that. I wouldn't recommend it.

you mean like this??

Code: Select all

df -h
Filesystem                       Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00   10G  3.5G  6.6G  35% /
devtmpfs                          12G     0   12G   0% /dev
tmpfs                             12G   12K   12G   1% /dev/shm
tmpfs                             12G   17M   12G   1% /run
tmpfs                             12G     0   12G   0% /sys/fs/cgroup

/dev/mapper/VolGroup00-LogVol02   20G  2.6G   18G  13% /var
/dev/mapper/VolGroup10-LogVol00  125G   70G   56G  56% /usr/local
tmpfs                            1.0G  130M  895M  13% /var/nagiosramdisk

Ah, yeah if you're doing it like @SteveBeauchemin did that's perfectly fine. As long as the logical paths of things aren't fudged.

[SteveBeauchemin]

The important part of what I did was having a separate volume for data that was split off from the OS.

Notice the names:
/dev/mapper/VolGroup00
/dev/mapper/VolGroup10

Different volume groups mean different Disk IO hopefully. If you can force them to different Data Stores from each other, it is more isolated. That was my intent when I did this.

Thanks.

socgenindia,

Did that help answer your question?

[socgenindia]

hi,

Thank you for you reply. if we share the lun between primary secondary server , do we need to install the Nagios XI on both server ?

[mcapra]

Yes, because both servers will need (at a minimum) all the necessary system packages and subsystems that prop Nagios XI up.

[socgenindia]

Our idea is to install the nagios xi in external mount i.e /use/local and then mount to server A , and if server A go down then external link /use/local would get mount to server B using VCS cluster method. In this case how to install nagios XI on Server B .

We don't have any particular documentation for high availability setups. That's more in the wheelhouse of devops people and general consulting. We typically direct people to Linbit and their DRBD product.
