Hello,
I run my dpdk applications with "file-prefix" option, so I can run them
concurrently. I see that it creates a runtime directory under /var/run/dpdk. This
directory still persists after the application has terminated. The code calls
rte_eal_cleanup before exiting but that doesn't seem to remove the directory and its
content. In my setup I have to consistently bring my applications up, run then for short
period and terminate them, each application run picks a new file-prefix, thus creating
new directory under /var/run/dpdk. After enough number of runs the tempfs partition fills
up and results into rte_eal_init failure.
Is there a cleanup routine or sequence I need to implement to unlink this
directory? Your help is appreciated.
Chaitanya.
This is a natural consequence of how our multiprocessing works. Running
a secondary process *after* primary has already exited is a supported
use-case (meaning, primary won't clean up *everything* after itself -
only things that are not shared), and secondary processes may be running
as well (meaning, we cannot remove shared data because it may be used by
other processes).
I don't think it's possible to do this from within DPDK. Of course, you
could always use --in-memory mode if you don't use secondary processes.
