I noticed this the other day, and thought it was interesting. When the jailed property is set on a ZFS fileset, it affects the mountpoint within the jail. If your jail uses allow.mount.zfs (known as allow_mount_zfs when using iocage), the mountpoints become relative to the jail. For example, in my poudriere jail, this is what […]

In this post, I’m not exporting an iocage jail to another host. I am moving the entire iocage instance to another host. This is accomplished by doing a zfs export on the zpool, moving the drives to a new system, and doing a zfs import. The drive migration is covered in a previous post. In

Today is the day. Today I move a zpool from an R710 into an R720. The goal: all services on that zpool start running on the new host. Fortunately, that zpool is dedicated to jails, more or less. I have done some planning about this, including moving a poudriere on the R710 into a jail.

This post is all about moving poudriere from the host into a jail, but you could probably use it for creating a new jail and running poudriere in it. NOTE: If you’re looking for a jail configuration for poudriere, please refer to Configuration for running poudriere in a jail on FreeBSD 14 – it contains

Today the drive caddies arrived for the R720. I refer to the services provided by the R710, not the server itself. I will list those services later and outline how I want to move them. I could do all this over this coming weekend but I have already allocated that time to some errands I

I planned to create a zroot mirror when I installed FreeBSD on the R720 but the supplier shipped only one of the two purchased SSDs. Today the second drive arrived. Let’s create a zroot mirror. In this post: FreeBSD 12 man 8 zpool Posts I looked at: creating a mirrored ZFS Pool out of a

Over the years, I have learned not to rely on hostnames for important services. Hosts go away, new ones come in. I want to rely on, what I refer to as, service names. For example, instead of relying on a hostname for my ntp server, I have: $ host time time.int.unixathome.org has address 10.55.0.1 This

This post talks about how I reduced the power consumption on my Dell R720 by adjusting the configuration settings. In this post: Dell R720 Sources I found Taming a 12th gen Dell PowerEdge when I was researching data cables for the SAS card I was going to use. For the record, the cables referred to
