Good afternoon!
I’m trying to set l2arc_prefetch=0 via the GUI on the truenas Scale. an error is returned. What should I do, how can I change the variable?
Error ZFS module does not accept ‘l2arc_prefetch’ parameter.
Which version of TrueNAS?
Are you just looking to disable pre-fetch?
From AI:
To disable ZFS prefetching, set the zfs_prefetch_disable parameter to 1. This can be done through system tunables, typically by modifying the /etc/system file. Alternatively, for native ZFS on Linux, you can set it through module options, such as using modprobe zfs zfs_prefetch_disable=1 and creating a persistent configuration file in /etc/modprobe.d/
