systemd
provide more detail on failure during extraction
I get this when trying to run an extract of a rather large set of ISOs (some 30gb).
Failed to run synchronizer: Operation not permitted
Given the number of syscalls, I'd rather not trouble shoot with strace :)
Additionally, it might be nice if it could continue trying to extract further files (which might succeed) even though this one particular file failed.
This problem is not specific to extraction. I tried to create an OS tree archive as normal user and it failed with the same error message. Finding why did this fail took a while (because some files in /etc are not world readable), but casync should definitely print who caused the failure.
I stumpled upon this today, also getting
Failed to run synchronizer: No such process
As already said, the output of strace is quite overwhelming and some more context would make error message really helpful.
What I did figure out:
It happens when a file you extract is owned by some user not existing on the system you are extracting on. At least either running casync --without=user-names or creating that user both fixed it for me.
