Cached drives are not mirrored, but always striped. To increase the size of an existing L2ARC, stripe another cache device with it. Dedicated L2ARC devices cannot be shared between ZFS pools. A cache device failure does not affect the integrity of the pool, but can impact read performance. ...

This will increase the bandwidth of many RAIDZ1/2/3 VDEVs. Storage Freedom with TrueNAS SCALE One of the side benefits of the massive TrueNAS 12.0 and OpenZFS 2.0 work is TrueNAS SCALE. Next week we’ll release the second Beta version, TrueNAS SCALE 20.12 “Angelfish”. For most users,...
I have had for a while now an install of FreeNAS 11.2 (most recently U4) on a re-purposed Intel i7 4970K with 16 GB of RAM, 3x mixed size WD Purple hard drives (started with what I have and will slowly increase drives to match size) in Raid Z, 1x 1TB Purple hard drive stand...
The folks at iXsystems hopes this unification will improve development speed, increase the quality of the software, efficiency gains, simplified documentation, and other benefits. TrueNAS CORE is the offering that will be what FreeNAS was. TrueNAS CORE is community-supported, open-source, and foll...
Can you explain that "slog will cache your sync writes and turn them into async writes internally"? That is the one part I don't understand about SLOG or how zfs handles the intent log, write confirmations and the process of re-writing data on slog over to disk platters. I thou...

You can increase l2arc_write_max to a higher value but this has a few potential risks, so you'll want to adjust your tunables slowly (think "double at a time" not "10x at a time") and monitor the L2ARC hitrate and general read/write behavior of the array as you go. First, ...
Moreover, sometimes padding is inserted to better align blocks on disks (denoted by X in the above example), which may increase overhead. However, we have still not touched on two more core advantages of ZFS and it’s RAID management…...
