[Kernel-packages] [Bug 1847628] Re: When using swap in ZFS, system stops when you start using swap
Is there any hope that a swap on zvol with sync=standard at least doesn't hang/deadlock? Like: zfs create rpool/swap -V 2G -b $(getconf PAGESIZE) -o logbias=throughput -o sync=always -o primarycache=metadata -o secondarycache=none In my testing this didn't hang when swap got hit. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1847628 Title: When using swap in ZFS, system stops when you start using swap Status in Release Notes for Ubuntu: Fix Released Status in Native ZFS for Linux: New Status in ubiquity package in Ubuntu: Fix Released Status in zfs-linux package in Ubuntu: Won't Fix Bug description: # Problem When using swap in ZFS, system stops when you start using swap. > stress --vm 100 if you doing swapoff will only occur OOM and the system will not stop. # Environment jehos@MacBuntu:~$ lsb_release -a No LSB modules are available.

[Kernel-packages] [Bug 1847628] Re: When using swap in ZFS, system stops when you start using swap
A swapfile on ZFS is a bad idea.
