I tried that and got a different error message: # mdadm --assemble --verbose --invalid-backup --force --backup-file=/home/gwr/2015/2015-08/grow_md6.bak /dev/md4 $OVERLAYS mdadm: looking for devices for /dev/md4 mdadm: /dev/mapper/sdd4 is identified as a member of /dev/md4, slot 0. mdadm: /dev/mapper/sdc4 is identified as a member of /dev/md4, slot 1. mdadm: /dev/mapper/sdg4 is identified as a member of /dev/md4, slot 2. mdadm: /dev/mapper/sdh1 is identified as a member of /dev/md4, slot 3. mdadm: /dev/mapper/sdi1 is identified as a member of /dev/md4, slot 5. mdadm: /dev/mapper/sdj1 is identified as a member of /dev/md4, slot 4. mdadm: /dev/md4 has an active reshape - checking if critical section needs to be restored mdadm: No backup metadata on /home/gwr/2015/2015-08/grow_md6.bak mdadm: Failed to find backup of critical section mdadm: continuing without restoring backup mdadm: added /dev/mapper/sdc4 to /dev/md4 as 1 mdadm: added /dev/mapper/sdg4 to /dev/md4 as 2 mdadm: added /dev/mapper/sdh1 to /dev/md4 as 3 mdadm: added /dev/mapper/sdj1 to /dev/md4 as 4 mdadm: added /dev/mapper/sdi1 to /dev/md4 as 5 mdadm: added /dev/mapper/sdd4 to /dev/md4 as 0 mdadm: failed to RUN_ARRAY /dev/md4: Invalid argument > If you get the array up and running again but it's still reshaping but at > position 0, issue a --continue to it (this has worked for others).

I'm up to mdadm v3.2.4 now, which is the latest version offered by the Fedora 22 update repo (and Fedora 23 doesn't offer a newer one): # mdadm --version mdadm - v3.3.4 - 3rd August 2015 Thanks again. -- George Rapp (Pataskala, OH) Home: george.rapp -- at -- gmail.com LinkedIn profile: https://www.linkedin.com/in/georgerapp Phone: +1 740 936 RAPP (740 936 7277) -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
