Changing partitions and zfs disklayout without downtime?

When setting up my SSD zpool – which I basically wanted because I wanted *no* constant disk-access to my disk-based zpool, I was lazy. Laziness almost never pays off. Before starting with ZFS, I had almost my full SSD as an LVM physical volume (except the bootdisk). Then, I added my external disk cabinet and… Fortsett å lese Changing partitions and zfs disklayout without downtime?

Todays hack: Integrating a proprietary alarm and lock system into home assistant

Last week, we got our alarm system from alarm.com (yup. I dare say which vendor. Security by obscurity is no such thing) set up.

Serveren er en Intel NUC, med Intel Core i5-8259U, 2.30 Ghz, med 16 GB minne. Opprinnelig ble den innkjøpt for å kjøre Home Assistant, hjemme-automatiseringen min.

IPv6, Canal Digital og Linux.

Canal Digital tilbyr, som en av ikke altfor mange norske ISPer ennå, nå IPV6 til kundene! De har derimot bare brukerguide for den trådløse ruteren de tilbyr. Jeg hadde allerede trådløs ruter, og bestemte meg for å sette opp en Linux-maskin som gateway mot Canal Digital. Linux har god støtte for IPV6, så dette burde… Fortsett å lese IPv6, Canal Digital og Linux.
