We recently replaced a couple of failed drives in our MD3260 storage array, and have been experiencing issues with the rebuild process. For context, our array contains thirty 4 TB HDDs arranged as follows:
We replaced one drive (0-0-7) in dg1 and one drive (0-3-3) in dg2. The drive we replaced in dg2 rebuilt without issue on both virtual disks, but the rebuild of dg1-vd1 is frozen and I originally believed it to be due to unreadable sectors but now I'm not sure... To summarize the issues I've been seeing over this process:
We've been working on temporarily moving all data off the device for expected maintenance. My primary question is with all data off of the virtual disks, would I be able to delete and re-create the offending virtual disks even with reconstruction operations pending/in-progress? I've found conflicting information as to whether or not that will cause other problems. If that is not possible, or if there's an easier method to fixing this than deletion/re-creation, what do you suggest as a next course of action?
Thanks in advance for any help you can provide
First off when you replace a drive in an MD32xx you don’t want to reseat the drive if it stops rebuilding as that will cause the drive to be flagged as bad. If you can send me the support bundle from your MD3260, then I can review it to see what the best way would be to get the virtual disk back online. You may need to destroy and recreate the virtual disk and then restore data but will need to look at the logs to be sure. I will send you a private message so that you can send me the support bundle.
Please let us know if you have any other questions.
