jeff0628 Posted October 31, 2015 Share Posted October 31, 2015 I have a question regarding data protection. I had a v5 unraid server with 1P, 5D drives with 9TB total storage, ran perfect for the last 5+ years. Recently decided to upgrade to v6.1.3. My storage requirements have also changed and no longer need the 9TB. So, I rebuilt and currently I'm running a single 2TB parity and a single 2TB data drive running v6.1.3. Since the drives are 5+ years old, I don't expect them to last too much longer. Question: With just the 2 drives, can either one be rebuilt from the other? Can the single parity rebuild the single data drive and vice versa? If not, why? What can I do to ensure I'm protected? TIA. Quote Link to comment
BRiT Posted October 31, 2015 Share Posted October 31, 2015 Yes. The parity protected array can be fully rebuilt on a single drive failure. Quote Link to comment
trurl Posted October 31, 2015 Share Posted October 31, 2015 But even so, don't overlook the importance of backups. The only thing that counts as a backup of a file is an extra copy of the file somewhere. Quote Link to comment
jeff0628 Posted November 1, 2015 Author Share Posted November 1, 2015 I do have other copies, i just wanted to make sure I can rebuild the single data drive if/when it fails. If I understand correctly, unraid can recover any single drive failure, regardless of the total number of drives making up the server, providing the parity is correct. Quote Link to comment
