When to replace hard drive in a RAID array
-
When I started at my current place, we had an 8TB OBR5 with a failed disk, and our MSP didn't even notice it during maintenance...
How they weren't fired immediately I have no clue.... restoring the entire thing would've ticked me off to no end. We got super lucky and the resilver completed without issue. Something like 23% chance of success... . .
This system is now gone..

What is your storage footprint like? % used/free.
Can you buy a two bay synology for under $200 on amazon and get some drives for it, copy your stuff there and blow away?
Remember you cant have 5 drives in R10, with your setup at least.
2 pairs of the 3tb drives, so you only get 6TB then a hotspare, but the space you loose. So think of that.. Will you need larger drives? What is your growth like? -
@Texkonc Yeah, I know I can't have 5 in a RAID 10. Currently we're using under 500 GB of this storage, so losing that drive isn't significant. Once my current two hair-on-fire esque tasks are done, I'll get on figuring out the procedure.

Only 500GB!
Go to staples now and buy a 1TB external and move the data off of this array.

@EddieJennings And growth? 500 GB in about 6 years (which I believe is the age of the NAS and its drives).

Moving the 500GB off of this and onto a USB 1TB would likely be way faster than trying to resilver too.
Send someone out to get a drive now, don't "wait to finish putting out those fires".

If you have 500GB in use today, and its been in place over the past 6 years, your delta is tiny.
You'd be fine with a 2 bay with 2x2TB drives in RAID1.

I'm with Dustin, go to Walmart and fix this, this instant. If the data isn't worth $100, then scrap the whole thing. If the company can't come up with $100, find a different job. In all other cases, just fix it right now

Hell $100, I'm seeing drives in stock at my local staples and walmart for under $60!

That's awesome news man, you have 4 good drives left to make a sexy OBR10 array that will serve them well for years
-
Hell, he has a Synology. He should be able to add the spare drive he has as a standalone disk. Move the share. nuke the array and rebuild with the 4 good drive and then move the share back.

Oh yeah. That makes sense.
