Given your link to the ZFS-related post, I assume that you use ZFS on the device. If so: with or without OpenZFS kernel module? <https://forums.FreeBSD.org/threads/79169/post-529408> I see that with FreeBSD 14.0-CURRENT, this occurs: trim: open failed: /dev/da7: Operation not permitted – when, for example, a partition within the device is a cache vdev for a pool.
