Reload to refresh your session. The weird thing is that I can't explain this high memory usage. However, this did not affect memory usage at all. (Unless I need to reboot for the change to take effect?) You can find my current arc_summary.py output here: https://0x0.st/MFJ.txt This is have a peek here This memory (which I can directly account for) adds up to 14 GiB (43%), leaving behind 10 GiB of memory in use by zfs's various slabs.

One thing I noticed while inspecting /proc/spl/kmem/slab is that the zio_data_buf_131072 usage is extremely high: https://0x0.st/SOb.txt (6 GiB in total). Together, this means that my system should be consuming 11+3 = 14 GiB of memory, meaning my usage should be 14/32 ≈ 43%, rather than 60%. Edit: I just realized, spl_kmem_cache_slab_limit is a lower limit, not an upper limit. with Help from Jekyll and Bootstrap Articles are licensed under the CC BY 3.0
What are these 10 GB currently doing?
