One of the ambassadors tried running with 250GB plot and it succeeded, just took about 5 days to sync and plot, so everything appears to be working.
In my case the issue might be an unstable connection hence the ETA was unrealistic and I saw no progress in plotting.
I think I have a similar issue with 100GB plot. Synced in a day, but only plotted 1GiB in the next day. The expectation is now 196 days… ./subspace-cli-macos-aarch64-v0.1.9-alpha farm Starting node ... Node started successfully! Starting farmer ... Farmer started successfully!
