I think you're going to be kind of on your own with this. Running containerd or docker on nfs isn't really done. If you need to run on diskless nodes I'd probably use iscsi or something else like that to expose a traditional block device and then put ext4 or xfs on it, since those are the two filesystems that both of those projects are tested against. The native snapshotter is barely more than a "better than nothing" naive implementation and putting that on top of nfs just makes it worse. It's cool that it worked for you for so long but honestly I'm surprised.

Hey, thanks for the reply! Yeah i was kind of surprised it worked too, but it was as simple as just setting docker back in 1.18 and off it went, no problems. I can look into iSCSI, as it's all off a TrueNAS box, maybe just mounting the volume as the containerd directory would be easier than trying to boot from it but I'll see. Shame it's not as simple as getting devmapper to work though, but I hear you on it being kind of uncharted!

there is an lvm snapshotter as well, but I’d go the iscsi route like brandond said with a filesystem like ext4 or xfs directly

thx @early-sundown-21192 - in the spirit of speed and getting my cluster back online I've decided to do something in-between and just mount an iSCSI volume at
and leave the rest on NFS, rather than try to figure out iSCSI boot at this time I have it working on one node since last night and so far, it seems to work well, just need to repeat for the others 🙂
