https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=262595 Bug ID: 262595 Summary: Swap on ZFS doesn't work properly. 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: firstname.lastname@example.org On one of my FreeBSD hosts I use swap on ZFS configured this way: ``` zfs create -V 64gb -o org.freebsd:swap=on -o checksum=off -o compression=off -o dedup=off -o sync=disabled -o primarycache=none zroot/swap swapon /dev/zvol/zroot/swap ``` The thing is… the swap is used in 1% there but I get OOMs from the kernel with Influxdb using a bit over 50G RSS. Had exactly the same issue on one arm64 machine also with ZFS, crashing the same way… having gigabytes of free swap available. Seems like swap on ZFS is not a real thing, or it simply doesn't work well? -- You are receiving this mail because: You are the assignee for the bug.
