Product: Base System Version: 13.0-RELEASE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: risner@stdio.com I'm building a system with limited redundancy consisting of a raidz1 array = 18 TB drives holding ephemeral data (not backed up) and a mirrored special vde= v on SSD for metadata and smaller files (being backed up). In my research I hoped to use zfs_max_missing_tvds=3D2 and mount read-only = to copy the small files to a new pool and destroy the ephemeral data? It looks like there is no way to enable this option in FreeBSD, yet it is covered in man zfs-module-parameters? Linux has it accessible via the /sys filesystem. Is there a reason it's not something that can be set from sysctl or /boot/loader.conf? --=20 You are receiving this mail because: You are the assignee for the bug.=
