[Bug 1629118] Re: lxd init should set compression=lz4 on ZFS
I see that you're only setting compression=on as part of zpool create, so this only applies when lxd creates the pool. I think that's a reasonable decision (figuring that if the admin created the pool, they've already made a policy decision on compression). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1629118 Title: lxd init should set compression=lz4 on ZFS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxd/+bug/1629118/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1629118] Re: lxd init should set compression=lz4 on ZFS
Right, because these are *containers*, so it's a filesystem tree, not a single device. I'm so used to full VMs. So this all sounds great and fixed.

[Bug 1629118] Re: lxd init should set compression=lz4 on ZFS
LXD itself doesn't care about the atime, though we could potentially use it to reduce overhead to figure out the last time some resource was used (rather than track in our database). But where it matters is for the container itself. Some workloads do care about atime, such as file servers, file indexing services, some databases, ... and we have no idea what the user is going to use the container for, so just turning it off isn't really an option. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1629118 Title: lxd init should set compression=lz4 on ZFS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxd/+bug/1629118/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1629118] Re: lxd init should set compression=lz4 on ZFS
I'm not sure how the workload is a factor. Is there ever a case where lxd needs the atime value for these files? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1629118 Title: lxd init should set compression=lz4 on ZFS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxd/+bug/1629118/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1629118] Re: lxd init should set compression=lz4 on ZFS
We did not disable atime. We'd rather people opt into that if they know it's fine for their workloads. It's really just a matter of them setting "zfs set atime=off " at any point in time, whereas compression makes sense to do right from the start. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1629118 Title: lxd init should set compression=lz4 on ZFS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxd/+bug/1629118/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Cool.
