Too many open files¶
When migrating a large installation of MSR 2.9.x to MSR 3.0.x, MMT can fail due to too many files being open. If this happens, the following error message will display:
failed to extract blob data to filesystem: failed to copy file <filename>
from storage driver to <registry name>: error creating file: <filename>:
open <filename>: too many open files
To resolve the issue, run the following command in the terminal where you are running MMT:
ulimit -n 1048576
