Migrate Logs and Data to new drives

[nathanplatt]

Hi Guys,

I've installed a new raid onto the server and want to transfer the data from the current drive to the new raid, can i just move the RRD files and and logs rather than re-installing the whole program to the other drive? I also want to do this for LogServer as well... is this nice and easy or a lot of time and effort?

When you mention you've installed a new raid onto the server, can you please clarify? Are you deploying a new core server, or have you just added additional disks?

As we're in the Core section here, could you please make a new post in the NLS forum relating to it? We do like to keep things isolated to one issue per thread.

I've added new drives, will open another case for NLS thanks

Are you using LVM on the server?

HI,

Sorry its taken me ages, but it is LVM. Home has its own partition.

As long as the paths remain the same, nagios should not care (or know) which drive it is stored on, as this is handled as an abstraction by the filesystem.

Brilliant thank you for all the help guys, please close the case.
