While running a local 'rsync -avP', the following error was reported:
rsync: writefd_unbuffered failed to write 32768 bytes: phase
"unknown": No buffer space available
rsync error: error in rsync protocol data stream (code 12) at io.c(515)
In this case, it appears that this was due to running out of disk
space, but "No buffer space available" did not lead us to that
Also, this error sometimes showed up immediately, at other times, it
occurred part way through the copy of the failing file, so that made
diagnosis even more difficult, as this appeared to be a rsync issue
rather than a disk space issue.
Version-Release number of selected component (if applicable):
This was 100% reproducable during a low disk space condition.
Steps to Reproduce:
1. Try to copy a file set larger than the available disk space.
The error messages above.
Something along the lines of "No space left on device" would have lead
us to the real cause sooner.
