I use a linux server as my store's data storage.
I have linux installed on 2x 250GB hdd.
The first HDD failed this morning. The system still boots fine if I leave both the HDD intact. It just run the system with 1 out of 2 drives.
However, if I remove the first (failed) HDD, the system no longer boots, I suspect it's the bootloader record is stored in the first HDD.
I need advise on how I can remove first HDD and replace it. From my understanding, if I remove the first HDD, the system won't boot and I won't be able to put in a new HDD to sync with the second HDD.
Thanks in advance for your valuable information.
