My Windows 10 plotter has been running for 22 days.
Once, every few months, some resource runs out, and my plotting on its associated NVMe drive stalls.
Today, it ran out of disk space. Why? Who knows. For 22 days it never got low on space.
As such, the plotting stalls (it keeps waiting 5 minutes for space to be available, and tries again). So I killed one of the k33 plotting sessions, and deleted all of its associated tmp files. That freed up a few hundred gigabytes of space, the the remaining k34 plotter continued – sort of.
It plotted for another 20 or 30 minutes, and it stalled. Still hundreds of gigabytes were free, and this time, no complaints from the plotting job. It just stalled. I waited 2 hours, and it did nothing. Task Manager showed no reads/writes to that NVMe drive.
So I killed that last plotting job, and I deleted all of its associated tmp files.
This should have made 100% of the NVMe drive’s space available, but it did not.
Of the 2 TB capacity of the NVMe drive, only 1.4 TB became available, and yet there were zero files on the drive (other than the directory files, which effectively use zero bytes). No hidden or system files. Simply zero files, and 600 GB of space is missing.
This happens once every few months. Upon rebooting, I get 100% of my space back. Everything returns to normal.
I would rather not do a reboot, but I do not know any other way to “reset” the space on the drive.
I have not yet rebooted the PC, because other plotting it still running on a different NVMe drive.
When that other plotting completes, I will do a reboot.
Something is holding on to file space.
Can anyone offer a way to identify what is holding on to the space, and how I can have it release the space, thereby not forcing me to do a reboot?
