Hi all!.

How can i move a disk space from /dev/mapper/centos-home to /dev/mapper/centos-root ?

  • I checked with df -h and my centos-root is almost full. I think that when it reaches 100% some process will not load.
  • I dont know wich files is on centos-root, maybe mysql?

Can you help me with the correct process to do that?, y dont want to lose all my performance data using a third web tutorial.

I´m using Centreon V20.04 and installed via package. The VM and space is all destinated for centreon central.

Thanks for your help. :raised_hands:

Hello @Rubenjif 

Important things to know before starting any opeartion on your fs are:

  • What kind of FS are you using (use `lvs` or `mount` command for example)
  • What the target partition layout for your needs (use the workbook proposed here) 
  • What kind of box is it? VM, Bare-Metal, Public Cloud instance? 

You can share answers to questions above and we’ll try our best to help. 

Note that the safest way to manage this would be to install a new server , configure manually the partitioning through the ISO menu, and migrate the data from one box to the other. 

You will have a lot of touchy and manual operation to get an optimized fs organization to work with Centreon, consider the aformentionned option.
