Hi,
I have two machines (in different locations) which has exactly same hardware as well as proxmox versions (4) running. The first machine was deployed two years ahead of the second one. The first server has more network transactions than the second one.
It is strange that smartctl states that the SSD used for ZIL and ZLARC in the second server deployed later worn out completely while the first one is intact. However 'zpool status' shows no errors and log and cache online to suspect whether smartct reports false positive? 'systemctl staus' shows datapool 'degraded', but zpool status shows no issues (ONLINE)!
Details below:
FIRSTOLDSEVER=2 HDDs single rpool + SSD for ZIL and ZLARC
SSDRAPIDWEAROUT= 4HDDs striped rpool and striped datapool + SSD for ZIL and ZLARC
The outputs are as of below:
