Jarrodr Posted August 17, 2022 Share Posted August 17, 2022 (edited) Hi All, I bought a 4tb to replacement my Parity, I haven't installed yet though. I have a dilemma, Issue: I have a corrupt disk and want to replace it. Requirement: Parity - 4tb (new) Disk 1 - remains the same. Disk - 3tb (using the old parity drive) How do I replace the parity and disk with losing data?

JorgeB Posted August 17, 2022 Share Posted August 17, 2022 When complete the parity swap procedure will have replaced both disks. 1 Quote Link to comment
itimpi Posted August 17, 2022 Share Posted August 17, 2022 For some reason the phrase Parity Swap is not acting as a hyperlink to the relevant part of the documentation, so here is the link. 1 Quote Link to comment
trurl Posted August 17, 2022 Share Posted August 17, 2022 6 hours ago, Jarrodr said: have a corrupt disk and want to replace it The disk is disabled, not corrupt. If it were corrupt, filesystem repair would be the correct fix, rebuilding from parity typically won't fix filesystem corruption. Emulated disk2 has 1.5+ TB contents. Disk2 does look like it should have been replaced before now, assuming that is the SMART report for disk2 you attached. Can't confirm since screenshot doesn't show serial. Do you have Notifications setup to alert you by email or other agent as soon as a problem is detected? Do any of your other disks have SMART warnings on the Dashboard page? Attach Diagnostics to your NEXT post in this thread. Quote Link to comment

You can acknowledge it by clicking 👎 and it will warn again if it increases. Since it is WD disk I am wondering about attributes 1 and 200 for that disk. Why are you doing read-check?

Jarrodr Posted August 18, 2022 Author Share Posted August 18, 2022 @trurl Not sure if this helps, I picked it up. I followed this yesterday, and no luck. Took some time. Quote Link to comment
itimpi Posted August 18, 2022 Share Posted August 18, 2022 Apparently nobody reads the documentation All the necessary steps are covered in this section of the online documentation accessible via the ‘Manual’ link at the bottom of the GUI. Quote Link to comment

Was hoping for a miracle :-|. Will have to replace the parity with the new drive first and then use the old parity drive as disk 2. Quote Link to comment

If you want to use a disk larger than parity you would have to do parity swap. That is not at all the same as replacing parity first. Please tell us what you want to do so we can make sure you are going to do the right thing. Quote Link to comment

Solution Jarrodr Posted August 19, 2022 Author Solution Share Posted August 19, 2022 Resolved. Installed the new drive. With the array off, assign the new drive as a parity and old parity as a new disk. Start array, it copies the parity then installs the new disk. Quote Link to comment
