Specifically, adding a Cache vdev to a new or existing pool and allocating drives to that pool enables L2ARC for that specific storage pool. Cached drives are always striped, not mirrored. The downside of increasing the throttling is CPU consumption: the L2ARC periodically scans the ARC to find buffers to cache, based on the throttling size. If you increase the throttling but the pool disks cannot keep up, you burn CPU needlessly. In extreme cases of tuning, this can consume an entire CPU for the ARC scan.TrueNAS is setup as follows. * 2 x vdev pools of 8 drives with z1. * L2ARC is using the Crucial NVME. * 2 x 1TB SSD in raid 0 for log drive. * 1 x 1TB SSD as the dedup drive (not sure this actually does anything ). military vehicle supply. vmi wheelchair lift demag kbk; rain bird esp 6 troubleshooting tomorrowland 2022 lieder;.
