Upgrading localbase on 13.0-CURRENT using ports-mgmt/synth

I upgraded base from 12.0-ALPHA9 to 13.0-CURRENT (r339639) on a VM today. While preparing for rebuilding localbase, I wiped clean /var/synth/live_packages/{All,Latest}/*, and cleaned the ccache repo stored in /var/cache/ccache. Trouble arose when I ordered ports-mgmt/synth to rebuild some 116 ports according to a specification stored in a local metaport.

iperf3 and Chelsio T6225-CR

I ran four tests yesterday using iperf3. The T6225-CR NIC still runs with Chelsio’s SM10G-SR optics. It’s amazing that receiving TCP streams runs at full speed. Sending TCP streams limps away only at a few megabits per second. This wasn’t expected at all. Even IPv6 runs faster than IPv4 for these particular tests. The Cisco switch at the other end uses Fiberworks’ SFP-10G-SR optics. Does anyone have any clues? Continue reading iperf3 and Chelsio T6225-CR

Chelsio T6225-CR and SM10G-SR

I finally got my two Chelsio SM10G-SR SFP+ optical modules. First light have finally been achieved.

Chelsio T6225-CR and SM25G-SR

I recently ordered a Chelsio T6225-CR network interface card and a couple of SM25G-SR SFP28 optical modules.

The aim is to get a 10 Gbit/s connection to the LAN, utilise the off-load capabilities of the NIC, and of course utilise the on-board crypto accelerator. The latter will not be useable until the system moves to the upcoming stable/12 branch.

Speaking of stable/12, I look forward to encrypted crash dumps and linear ZFS scrubbing.

I hope both OpenSSH and OpenSSL will be able to use the crypto accelerator by ways of crypto(4). Imagine a crypto speed in excess of 30 Gbit/s. That’s pretty neat. If all goes well, another T6225-CR may find its way to a VPN router.

Migrating UFS filesystem from one disk to another

I needed to migrate an UFS filesystem from one disk to another. I had several options including using two tar processes in a pipeline or using dump and restore in a pipeline. I opted for the latter to make sure everything got preserved during the transfer.

Here’s the sequence of commands where /dev/gpt/nroot0 is the GPT label of the new filesystem and / is the donor filesystem:

newfs /dev/gpt/nroot0
mount /dev/gpt/nroot0 /mnt
cd /mnt
rmdir .snap
dump -0LaP 'restore -rf -' /
cd /
umount /mnt

efi_max_resolution needed on base/head for UEFI systems without FHD displays

r331464 added efi_max_resolution. If you run base/head on monitors without Full HD (FHD), then you might need to specify your desired resolution in /boot/loader.conf.

This should suffice for a resolution of 1280×1024 on 19 inches displays.

efi_max_resolution="1280x1024"
