ReadyNAS Ultra 6 hot swap resync error
Hello, I am running a ReadyNAS Ultra 6 with RAIDiator 4.2.31. I have been running with all 6 disk bays full for years, and I had started to approach the capacity of the RAID array (91%). I had ...
I'd love to hear any suggestions before I swap out HDD 1 and likely lose the entire data array. Many thanks for sharing any thoughts.
Is HDD1 also a green drive? I have seen drives declared "dead" in OS4.2.x because they failed to spin up as fast as the rest. If HDD1 is now the only green drive, that could be the issue. There certainly does seem to be a big risk of losing the array if you swap out HDD1, but I don't think you have a lot of options. You could try cloning HDD1 to another drive, but there is still some risk there. Just make sure your backup is up to date and hope you don't have to take the time to reestore it.
Thank you for the reply, Sandshark! Strangely, HDD1 is actually a 4TB WD Red drive that I installed within the last year. Bad luck on this early failure while hot swapping another drive, I suppose.
Sadly, I think that you are correct that I don't have many options here. I'll look into cloning HDD1; thanks for the advice. Luckily, I do have a current backup of all data. I'm just not looking forward to spending many days (weeks?) restoring everything.
Cheers,

So I ended up swapping out the malfunctioning <1-year-old WD Red 4TB HDD1 and lost the volume. It's OK, because I have backups.
With new HDDs in Bays 1 and 6, I then performed a factory reset to build a new volume and then restored my configuration settings. I started restoring from backup overnight, but I awoke this morning to find that HDD3 has now failed. This is a >5-year-old WD Green 2TB HDD, so it's possibly true (as suspected by Sandshark); however, a bunch of failures at the same time makes me suspicious of a global hardware problem in the NAS. Can someone please suggest any appropriate diagnostics to run to ensure that my NAS hardware is operating properly, before I buy and swap in a new HDD3?
The saga continues... (*sigh*) Thanks for suggestions, everyone.
