Reveal Solution Hide Solution
Correct Answer: A, D

The error message ''wafl.cp.toolong:error'' indicates that a WAFL consistency point (CP) took longer than 30 seconds to complete. A CP is a process that flushes the data from the NVRAM buffer to the disk.A long CP can cause latency and performance issues for the system1

One possible cause for a long CP is excessive SSD load causing the wear leveling to become unbalanced. Wear leveling is a technique that distributes the write operations evenly across the SSD cells to extend the lifespan of the SSD.If some SSD cells are written more frequently than others, the wear leveling will become unbalanced and the SSD performance will degrade2

Another possible cause for a long CP is an SSD disk performing garbage collection to create a dense data layout. Garbage collection is a process that reclaims the space occupied by invalid or deleted data on the SSD.Garbage collection can improve the write performance and storage efficiency of the SSD, but it can also consume CPU and disk resources and cause long CPs3

A disk failing or being failed is not a likely cause for a long CP, because the system will automatically mark the disk as failed and remove it from the aggregate.The system will also initiate a disk reconstruction or a RAID scrub to restore the data protection and redundancy4

There is no evidence that the system has SATA HDDs, so there is no reason to assume that there is excessive SATA HDD load.Moreover, SATA HDDs are usually used for secondary or backup storage, not for primary or performance-sensitive workloads5
