Dvc: pyfastcopy causes BlockingIOError

Please provide information about your setup

DVC version: 0.83.0
Python version: 3.6.9
Platform: Linux-4.12.14-150.38-default-x86_64-with-glibc2.9
Binary: False
Package: pip
Cache: reflink - not supported, hardlink - supported, symlink - supported
Filesystem type (cache directory): ('gpfs', 'tlhome2')
Filesystem type (workspace): ('gpfs', 'tlhome2')


I am getting the error BlockingIOError: [Errno 11] Resource temporarily unavailable when running dvc checkout. This has been solved by uninstalling pyfastcopy, but for future reference I am submitting it as a bug report.

Unfortunately I don't have access to a Linux setup to test that module, I just put in the code for symmetry with the Windows version. If nobody is complaining about Linux network perf you can probably just leave it out and wait for the transition to Python 3.8.

Otherwise it might be worth a bug report to the upstream project, but with no possibility to test it I'll have to let someone else handle that.

Hi @murnanedaniel !

Thanks for the report! We've removed pyfastcopy from deps for now, will release a new version soon.

Need to revisit pyfastcopy in general, not liking these BlockingIOError errors popping up.
