We have a server that was being decommissioned and it was thought that all the data and services had been migrated to new systems. Instructions to our tech was to remove drives and prepare the system for recycling. Just before this was done it was discovered that one of the virtual instances hosted on this system had not been correctly migrated and now we need to spin up the server again. This system was built by a previous tech who didn't document the system well and therefore we are left with little information to go on, other than the HOST OS is some form of Ubuntu hypervisor and the guests are in separate partitions managed by the host in a software RAID configuration. - There are 10 SATA disks … we don't know the original order as the system was slated for decommission.
Question : Can we just plug in the drives and hope it boots? Do we need to find the drive with the OS on it?
