I remarked to a local computer repair shop that I have a four TB backup drive. He said "replace it. Four TB isn't ready yet."
How so? I though 4TB is showing its age...
I'm running 12x 4TB drives. Used SAS drives. Accumulated power on time ranges from 40,166 to 73,439 hours.
Smartctl informs me device /dev/sdf is worsening with increased read errors over time. That one shows 73408 hours powered up, 72360.67 GB read, 119545.193 GB written, 195 power cycles (13 since July 13 2024). Defect list increased from 3 to 6872.
I see two other drives have defect lists of 23 and 14, respectively. All others are at 0. Considering that, I should probably prioritize replacing at least sdf soon to avoid losing redundancy during resilver, considering the age of the pool.
