migrated to a raid 5 array. Same deal, got to 50% quickly then stopped. processor back to normal, 17 hours passed, still migrating, restarted anyway, against manuals instructions, all seems ok. Nothing else was happening. Hope all is ok. Dont know if its the disks, the software or a hardware problem. Anyway, hoping all will progress from here OK, had most data backed up, hard to do totally with a 6 TB array.
Has anyone ever seen this stuff before?
