Hello Everyone,
I have been having some vSAN issues where drives will show degraded when in actuality they are fine confirmed by in LSI controller and via hardware status. The drives (SSD) seem to become degraded once I/O hits the disks like (i.e. creating a VM). All hosts have 2 x SSD with one of those SSD tagged as a HDD. I wrote a post about it back in March here which has screenshots and more detail. Life has been very busy (chasing my 17 month around ) finally have time to continue troubleshooting. Everything is on the HCL for vSAN expect the actual SSD drives.
Below is the hardware specs:
Hosts:
Supermicro Servers (X9SCM-F) x 2:
- CPU: 2 x Intel Xeon E3-1230v2 “Ivy Bridge”
- Motherboard:2 x Supermicro X9SCM-F
- Raid Controller:2 x LSI Internal SATA/SAS 9211-8i
- Memory:2 x Kingston 32GB Kit DDR3 1600MHz PC3
- Disks:2 x Lexar Echo ZX 16GB
- SSD: 4 x Sandisk Ultra II 240GB
- Network Cards:
- 2 x HP Infiniband DDR Dual Port HCA Adapter 20Gbps
- 2 x HP NC360T Dual Port PCI-e Gigabit Card
- Power Supply: 2 x Seasonic 400W 80 Plus Platinum Fanless ATX12V/EPS12V
Supermicro X10SAE-O:
- CPU: Intel Xeon E3-1231 “Haswell”
- Motherboard: Supermicro X10SAE-O
- Raid Controller: LSI Internal SATA/SAS 9211-8i
- Memory: Kingston 32GB Kit DDR3 1600MHz PC3
- Disks:
