I am planning to replace my motherboard to get one with additional functionality. I currently have a volume group that spans multiple physical HDD. I plan to use the same o/s disk/config (just shut down, swap mother board, reboot).
Am I in danger of breaking the volume group and loosing the data since the device name may change? If so, what can be done to keep the data (other than the obvious back it up).
edit: adding background history. This is my first experience with any flavor of Linux. My o/s experience is in VMS where physical device name is significant. I started this PC project to learn a new o/s (a retirement project). My concern is that since the devices are SATA connected, the port they connect to on the motherboard seems to control their device id (SDA, SDB, etc). So, I was concerned that if the way I connected the HDD so the motherboard might cause them to get a different device ID. If that happened, I am fearful that it would break the logical volume that spans multiple physical HDD. If the logical volume is made of SDA, SDB and SDC on the current system. Would the volume still mount and be intact if the same physical HDDs became SDC, SDE and SDF (as an example) or if the disk that is SDA on the current motherboard becomes SDB on the new motherboard. Would the change in device ID cause the logical volume to break.
