March 29, 20224 yr Hi All, I recently acquired 2 3.84TB Samsung PM1633 MZILS3T8HCJM SAS drives I want to use for my Cache Pool, but I'm having trouble adding them. I can select them in the Cache Drive dropdown, but when I start the array it just says "Unmountable: No pool uuid". I tried setting the filesystem to 'auto' with a single drive, but still get the error. I've attached the SMART reports but I don't know what they are saying. I'm using a LSI-9201-16e card, and a Xeon E5-2660 system. Any help is appreciated! Thanks! alexandria-smart-20220329-1419(1).zip Edited March 29, 20224 yr by Kainhander Clarification
March 29, 20224 yr Community Expert When you started the array after assigning the drives did you run the option to format unmountable disks?

No, I just tried to assign the drives and start the array initially. When that didn’t work I stopped the array, unassigned the second drive, set the file system to auto, and started the array again.
