I could imagine using kpartx to script a solution to (1) above, skipping over the md headers. Some kind of shim may be needed to fool the kernel to see a different UUID for each source volume so they can be mounted simultaneously without md.
The kernel can do it, on a fully operational array. cat /sys/block/md0/md/sync_action echo check > /sys/block/md0/md/sync_action cat /sys/block/md0/md/sync_action then cat /proc/mdstat cat /sys/block/md0/md/mismatch_cnt Regards. -- Roberto Ragusa mail at robertoragusa.it _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
