Thank you all for the very helpful advice:- If I understand you all the problems are ZFS is choking because I don't have enough disk space. The reason I don't have enough disk space is because the files I deleted are still in the old snapshots, plus it was already pretty full.
This seems like a good way forward but is it really and if so how do I do it? First things first ZFS is choking due to lack of disk space. However, I have a lot of totally unused diskspace on a windows partition so how can I reduce the windows partition and increase the ZFS to stop it choking. It has 560GB of which I do not need more than 200max to leave for Windoze. Gparted apparently doesn't like ZFS but does this matter? I can I assume use it to shrink the Windows partition and free up about 360GB, then how do I expand the ZFS to use that free space? Second, I have checked /etc/cron and find auto snap shot commands for hourly, daily, weekly & monthly hourly = 24, daily = 31, weekly = 8, monthly = 6. It seems I could change that to hourly = 24, daily = 7, weekly = 4, monthly = 6 and get pretty much the same coverage with a lot less snapshots. Listing snapshots shows some from 2019, where are they coming from as with monthly only storing 6 months there shouldn't be anything newer than February 2020 or am I not understanding something here? The computer is a Lenovo W541 laptop, the longer term plan is to double the memory to 32GB and put a 2TB SSD in this box. Does that sound sensible? In the meantime, a thorough backup is running in at least two external drives (one incremental and one fresh). Stripes.
