Could not delete share due to snapshot deletion failure, Code 1004030000 OS6
I have a ReadyNAS 316 OS 6.10.2 with 3x2TiB + 3x4TiB disks so currently at 12TiB. Seem to have a problem with one of my share folders. I am unable to delete a share due to a snapshot deletion error a...
Clearly the file system for the data volume has become corrupted somehow. The most conservative approach is to do a factory default, rebuild the NAS, and restore the data from backup.
If you purchased the NAS (new) between 1 June 2014 and 31 May 2016, then you have lifetime chat support at my.netgear.com. You could try using that if you have it.
SSH is another possibility - using it to manually delete the snapshots and share. You'd log in as root, using the NAS admin password.
You can list the btrfs subvolumes (e.g., shares and snapshots) with btrfs subvolume list /data
Then you can manually delete the ones you want to get rid of with btrfs subvolume delete <path>
You need to use the full name in the path (e.g., it needs to start with /data/OldChive ). When deleting snapshots you need to delete each one independently (something like /data/OldChive/.snapshots/XX/snapshot for each one).
StephenB Hey, I somehow clicked on my first reply to you as the "solution" do you know how to fix that?
I'm glad you figured it out. Subvolumes look like ordinary folders, but they aren't - and as you found, rm can't delete them.
It might be good to also run a balance. That will scan the allocated data and metadata. It will also consolidate more free space.

Yes, I've undone that, so you can pick a different post.
StephenB Thanks again!
I ran Balance from SSH, figured that was going to be more intense and comprehensive. Wish I had been less tired when I read your first reply, would have solved the problem more quickly.
I already selected that as the "Solution" and gave you a thumbs up.
Thanks for your knowledge and reply.
I haven't read your reply to my volume question post, expect I will be clicking another thumb there too.
Any recommendation on a Linux or Ubuntu to run as learning device, and or site to learn from?

ReadyNAS use Debian linux, but as far as learning goes I think ubuntu would also be fine. You can create a "live" disk for either, so you can boot up a normal x86 PC under linux for either variant.
https://www.debian.org/CD/live/
https://help.ubuntu.com/community/LiveCD
Note these don't need to be bootable CDs, you can also boot from a USB drive or a thumb drive (if it has enough capacity).
There is also a ReadyNAS VM out there, though that is more useful if you are wanting to test a specific package w/o risking installing it in your main NAS.
I don't have a recommendation on a learning/tutorial site; it would be good if someone else chimes in on that.
