So the > problem is specific to ZFS root. Now I think I know what is the source of problem. After all, on 13.0-RELEASE i386 system simply loading zfs module results in system hang up. The steps to reproduce it are, 1. Boot with install media of 13.0-RELEASE i386 2. At the first menu of FreeBSD installer, select 'Shell'. 3. At the shell prompt, type `kldload zfs` and return key. I confirmed hangup happens with VirtualBox, VMware Player and my bare metal PC environement. So the problem doesn't depend on hardware. And hangup also happens with 13-STABLE and 14-CURRENT. --- Yasuhiro Kimura ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

You're limited to 4 GB of memory space, so you need to tune the ARC to use less than that. The auto-tuning has improved a lot over the years, but you still need to limit the ARC size to around 2 GB (or less) to keep the system stable. KVA memory space tuning shouldn't be needed anymore, but you can do research into that, just in case. You can compile a custom kernel to enable PAE support, that will sometimes help with memory issues on i386 (and will allow you to use more than 4 GB of system RAM, although individual processes are still limited to 4 GB). If you really need to, you can make ZFS work on i386. If at all possible, though, you really should run it on amd64 instead. -- Freddie Cash fjwc...@gmail.com ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

I was somehow mistaken how the release.sh process works. I have a local tree with some modifications to the i386 GENERIC kernel config to hopefully get FreeBSD booted on an old Thinkpad X31. Just starting a release build with the default i386.conf always checks out HEAD, no matter of what branch I started the release build from. --Gordon ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

Install of 13.0-RELEASE i386 with ZFS root hangs up
Hello, Does anyone succeed to install 13.0-RELEASE i386 with ZFS root? I tried this with VirtualBox and VMware Player on Windows with following VM condition. * 4 CPUs * 8GB memory * 100GB disk * Bridge mode NIC But in both cases, VM gets high CPU load and hangs up after I moved to 'YES' at 'ZFS Configuration' menu and type return key. If I select UFS root installation completes successfully. So the problem is specific to ZFS root. --- Yasuhiro Kimura ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
