Error while writing unwrap output file

[yutingtai]

Hi everyone, I'm processing sentinel-1 5 years data on the WSL enviroment with ISCE, during the unwrapping step, I got an error:

Error while writing to file /mnt/d/.../filt_fine.unw (device full?)
Abort

I checked my device which is not full yet, and also the input files have the normal size in this step.
Does anyone have any idea about what happened to this error? or where can I start trying to find the issue?

thank you
