How to extend NSL storage

Hi,

We are currently using the CentOS image for the NLS server and would like find out how we can extend the storage on it?
Thanks.

Here is a manual on changing data paths for log server but it can be used to add space to the server.
The section "Adding Multiple Paths" describes that.

Hi Box293,

Instead of adding multipath, we would like to extend the existing storage.
What Linux command should we be using?

Thanks.

This document, while it is specific to Nagios XI, will also work for Log Server:

Hi,

When we ran the pvresize, we hit this error.
'-bash: pvresize: command not found".

I think it is better to have a new disk expansion guide specially for Nagios Log Server.

Yes I agree about the documentation.

To get you working now it looks like we need to install the dependencies.

Code: Select all

yum -y install lvm2

Now try pvresize

Hi,

We follow the nagios xi document and hit the 'Error 17' error after the reboot.
Hence, I do not advise other users to do the same for your production instance.

I still have 20GB left, which should last us for 9 days before it runs out of space.
Hopefully, by then, we have a documentation for Nagios Log Server.

Thanks.

You should always be able to extend LVM volumes assuming you have the disk space and that you formatted with ext3 or higher file systems. You said that you installed off the CentOS image - do you mean the VMware image that Nagios Enterprises provides?

hi, that is correct. We are using the VMware image.

You can also add a datastore path
