Cluster filesystem monitoring

[preethu.d]

Hi Team,

We have some filesystem which is in cluster mode. Can we know how to monitor these filesystem so that we are always monitoring the filesystem in active node?

Hi Preethu,

I just want to make sure we understand the problem you are trying to solve correctly. You have systems in an active/passive configuration sharing a filesystem and you want to monitor the filesystem through the system that is active state -- is that correct ? Also what type of systems are these and how are they mounting the filesystem ?


Thanks and Best Regards,

Hi Keith,

Wish you a very happy new year.
Yes, you are correct. These are LVM filesystems managed by cluster packages. Based on cluster status these filesystems moves to active node.

Hi Preethu,

Thank you - Happy New Year to you as well.

Is this Linux LVM or another Logical Volume Management system ? What operating system are you running on the devices that are mounting the filesystems ?

If you can monitor through a shared Virtual IP address (VIP) that is often the easiest way to solve the problem however check_cluster might also be a good way to go as well. Please find below links to our documentation on monitoring service and host clusters along with the manual page for the check_cluster plugin.
