Error in logging when restart from previous simulation without logging in API37

[XiulinGao]

Describe the issue

I found that in API37, when turn on logging in a hybrid run using restart file from previous simulation that did not activate logging, the model will report error that landunit dimension variable is expected to be 3 in the restart file. I then compared the restart files from simulations with (initialized with inventory file) vs without logging using API37, indeed found that the landunit variable is different (3 vs. 1 for the restart file with and without logging, respectively). My understanding is that when logging is not turned on in API37, restart file is written assuming landunit is 1 while when logging is turned on it changed to 3.

Not sure if this is already solved in recent versions of FATES or not, I also suspect this is probably a CTSM-site issue.

@XiulinGao was there log output associated with the issue? I don't see anything in that section above.

@glemieux the log file is overwritten already but it was saying "expected value for landunit is 3". I am also attaching two restart files from simulations with and without logging using API37, you can see the difference for landunit dimension and variables using this dimension between the two.

@XiulinGao thanks for the files. When you're turning on logging which fates_harvest_mode are you engaging?

[XiulinGao]

@glemieux I was using the "landuse_timeseries" mode, which basically is the approach FATES uses in older versions. But I'd suspect there's change on the CTSM side.

Thanks. I don't think this is currently possible with this FATES harvest mode, but I'm also not sure if its possible with ctsm. @ekluzek can you weigh in here? Is it possible to run a hybrid transient landuse case from a restart that wasn't transient?
