That doesn't look like RAID 6. That looks like RAID 5 with a hot spare. There appear to be two drives missing. If you can locate one of those two drives and add it to the array, you should be able to start it and mount the filesystem. Otherwise you'll have to restore backups.
The drive that failed this weekend may work well enough to add it to the array temporarily if you need to refresh your backups.
