So i added 2 new ironwolf 8tb nas drives to my readynas .
While it was syncing a drive failed .
after a couple of days the drives were synced and i took out the bad drive but now i still get the message my volume is degraded .
I started a disk test but how do i get my volume back to redundant .
Schould i put in another NEW drive in the bay the failed drive came out ? Schouldnt it have made the data redundant again with the 2 new drives added ?

What RAID mode are you running? I'm guessing RAID-6 (perhaps X-RAID with 8 or more drives)?
It sounds like you now have an empty slot - is that correct? If that is the case, then the NAS will report a degraded volume. If that is the situation, you do need to fill the slot with a new drive.
If the drive failure occurred after the second new drive started to sync, then the NAS had already configured the RAID to use that drive, it just needed to sync it. So, with one drive now removed, you're a drive short of how it's configured, so not redundant.
Failure of a drive during sync is always a possibility since it puts so much strain on all the drives. If you are using RAID5, then you are lucky you didn't lose the entire volume with that failure.
