Leave a Comment / homeassistant, Open Source / By / March 1, 2023

I have the Let’s Encrypt Add-on configured for my Home Assistant logon. I got it to renew. I see the cert is stored at /data/letsencrypt/live/hass.example.org/fullchain.pem. But I don’t see directory in my terminal session for Home Assistant. It’s as if I should just give up and use an Nginx proxy instead. At least I know …

Now that I’ve filled up data01, I bought some more SSDs and created another zpool. Today, on this snow-is-anticipated Saturday winter morning, I’m going to move some ZFS filesystems/datasets around. Side note: I like the term dataset better than filesystem. man zfs talks about datasets, which can be a file system, a volume, a snapshot, …

Wrong recordsize on zfs send | zfs recv filesystems

Leave a Comment / FreeBSD, Open Source, syncoid, ZFS / By / February 23, 2023

Over the past few days, I’ve posted a lot about transferring jails from two hosts into one host. One of the steps involves using zfs send | zfs recv to send the files from one host to another. I’m using syncoide for that transfer. A new fileystem’s recordsize defaults to 128K. In my case, that …
