@Mahdi_KamaliMahdi_Kamali**:** How can I fix these errors to set smp_affinity for disk IRQs successfully? Is it important?
Setting non-NVMe disks: sdf, sdc, sdh, sdb, sda, sdd, sdg, sde4...
Setting mask 00000001 in /proc/irq/191/smp_affinity: failed to write into /proc/irq/191/smp_affinity: (<class 'OSError'>, OSError(5, 'Input/output error'), <traceback object at 0x7f2abeaf0800>)
Setting mask 00000001 in /proc/irq/212/smp_affinity: failed to write into /proc/irq/212/smp_affinity: (<class 'OSError'>, OSError(5, 'Input/output error'), <traceback object at 0x7f2abeaf0840>)
@avi**:** Those disks probably don’t support it. There will be some performance loss.
