ReadyNAS OS6 6.7.3 Upgrade - Users With Full Root
Hi all, I haven't yet upgraded to 6.7.3 from 6.7.1 but I've seen numerous threads on here regarding the system failing to boot due a full root volume. My question to the Netgear team is wheth...
It was an issue with 6.7.3. It mainly affected systems where the root volume was fully allocated even if very little was actually used.
If you have updated to 6.7.3 and ran into this issue please try USB Boot Recovery with ReadyNAS OS 6.7.4 which is now available!
If you have not yet upgraded please upgrade to 6.7.4 rather than 6.7.3. If your system has already been fixed I would still suggest updating to 6.7.4 the normal way using the web admin GUI.
I'd also like to know whether to defer upgrading other units with 6.7.3 even if the current root partition looks ok?

OK Thanks... This is why I always defer upgrading for at least a month. I let others test for me. On a business system, running the latest and greatest isn't always the most stable.
Please can you advise what you mean by fully allocated vs fully used? If I remember correctly the root volume has 4GB allocated to it by default.
I'm talking about the BTRFS chunk allocation for data and metadata vs what is actually consumed. Empty chunks are returned to unallocated space, but chunks that aren't are not.
6.7.3 has a problem when all the space is allocated even if it's not actually in use. This is what's fixed in 6.7.4. The system should work fine with the space fully allocated.I now understand, thanks.
Does the upgrade check for any obvious issues prior to proceeding with the upgrade? I appreciate that wouldn't circumvent this issue but I am curious.
