When kdump on an Oracle VM Server is configured to use sparse files for vmcore dump files to reduce the dump file size, kdump fails with an error similar to:
Scanning and configuring dmraid supported devices ... cp: unrecognized option `--sparse=always' ...
Workaround: Add the following to
the kdump.conf
on the Oracle VM Server:
extra_bins /bin/cp core_collector /bin/cp --sparse=always
