This morning I turned on dual disk redundancy with plenty of free space available (over 60%), and the Drobo then sent 2 messages:
Notification: Drobo is converting to dual disk redundancy.
Critical Drobo Alert: Drobo cannot currently protect your data against hard drive failures.
The dashboard status indicates I need to provide “2 hard drives for single disk redundancy or 3 hard drives for dual disk redundancy.”
I have 1 3TB drive and 5 2TB’s - I replaced a 2TB with the 3TB on Friday and it finished rebuilding yesterday. I decided to turn on DDR before replacing more 2TB’s with 3TB’s in case of a drive failure as I did those.
Should I wait it out and hope its still converting to DDR?
1-6 are solid green, and #7 is solid red (7 total drives).
I opened a ticket with DR this morning, and they’ve come back to say it appears to be doing some sort of internal maintenance, and that I should reboot it tomorrow and then generate 2 back-to-back diagnostic files for them to review.
Interesting note in your sig about WD 3TB red drives - that’s what using to replace the existing 2TB greens in my Pro.
