I am able to reproduce this smart error now. I have done it twice, so maybe other things are causing this also. When I scanned the devices this morning with smartctl via webmin I lost 8 of the 9 drives. They are howerver still in my /dev folder. Now I sent out my logs from the first failure last night, smartctl was on the system... I dont know if ubuntu server's default smartd configuration makes it do periodic scans because I didnt change anything. I would hate to move back to 9.10 and see this problem again. Should I just not install smartmontools? This seems like a bad solution because now I wont be able to check the drives in advance for failures. Have you installed LSI's linux drivers? Some people say this solves their issue. >From the logs sent out last night do you think it could be something else?
