You may have very slight corruption from the data still in OS caches, but there's no help for that. Also use --verbose, and save the output for us in case there's further difficulties. > (Yes, there was a sixth member too, but I suffered a crash (kernel > kicked a controller with 5 disks on it) during the re-adding of that one > disk, so I have therefore deemed it unsafe to use for --assemble, so > that one is marked and put away safely) Yes, leave that one out. I also recommend getting any critical backups from the reassembled array before you attempt to add the missing drive.
