Best practice for replacing failing drive in a TWO Domain Controller domain

  • 772

Hi I have a two domain controller domain and i will refer to them as DC1 and DC2, here is some info on them.

  • DC1 is or has all FMSO roles
  • DC2 serves as another Domain Controller for replication
  • DC1 is a basic server with a 3ware RAID 1 setup
  • There is a buggy hard drive in DC1 and the 3ware rep recommends replacing the drive in slot 0 sooner than later.

Based on the above information I would like to know if the best practice way would be to move the FMSO roles to DC2 first and then turn off DC1, replace the bad drive and let it rebuild and then move the FSMO roles back to DC1. The reason I want the FSMO roles back to DC1 is that is is a one year old system whereas DC2 is about 6 years old and I don't want it to hold the roles.

Is there anything else I should be looking at too example would be should I move the roles and unjoin DC1 from the Domain and then do the steps above?

Any help is appreciated. Thanks.

    You don't need to do anything other than replace the failed drive. There's no need to move the FSMO roles, even if DC1 is offline for a short period of time. If for some reason DC1 can't be brought back online after the drive replacement then you can seize the FSMO roles. Here's some additional info:
