Tested against main RAID6, 7 disk array, with sas extender and work with out error. Tested against 2X mirror of SSD's, direct attached, and worked with out error. Check was a simple RAID check. "echo check > /sys/block/md126/md/sync_action" Patched against: root@nas:~# uname -a Linux nas 4.0.0 #1 SMP Thu Apr 16 09:05:59 PDT 2015 x86_64 GNU/Linux Many thanks to all involved in helping me debug this. Should this patch be tested by a few other then added to the kernel tree? On Thu, Apr 16, 2015 at 10:31 AM, Adam Talbot <ajtalbot1@xxxxxxxxx> wrote: > Oh!
