ZFS is the last word in the filesystem period. Many administrators are confused about using it – because ZFS is more than a filesystem. It introduces many new concepts. This blog’s mission is to bring ZFS to more homes/companies and show that we don’t need any other filesystem.

The ZedFS gathers information and tutorials about ZFS. If you are curious about ZFS, this website will become your home.

Ok, but why ZedFS?

There is an endless discussion if we should pronounce ZFS as ZeeFS or ZedFS. The debate is so hot that even Michael W Lucas and Allan Jude (the authors of the FreeBSD Mastery: Advanced ZFS) disagreed on how we should pronounce ZFS. Because of that, there is a Canadian version of the “ZedFS FreeBSD Mastery.” (The story of the book). If you are from the ZeeFS camp, then ‘ed’ in the blog’s name is from EDucation.

For many of us, memories of our childhood have become a bit hazy, if not vanishing entirely. But nobody really remembers much before the age of 4, because nearly all humans experience what's termed "infantile amnesia," in which memories that might have formed before that age seemingly vanish as we move through adolescence. And it's not just us; the phenomenon appears to occur in a number of our fellow mammals.

The simplest explanation for this would be that the systems that form long-term memories are simply immature and don't start working effectively until children hit the age of 4. But a recent animal experiment suggests that the situation in mice is more complex: the memories are there, they're just not normally accessible, although they can be re-activated. Now, a study that put human infants in an MRI tube suggests that memory activity starts by the age of 1, suggesting that the results in mice may apply to us.

Now an 11th-grader, Gallagher was back on the track for a Portland Interscholastic League meet at the athlete's home track, where Gallagher was spotted blowing out the competition, especially in the 400M, where the athlete finished more than seven seconds better than the rest of the field. //

There's a great way to end this. It will be painful and unfair for a time, but no less unfair than what's happening now. Every girls' team that faces a team with a male member should walk off the field. Every girl on a team that has a male member should walk away. Refuse to play the game. Refuse to dignify this by participating. Refuse. Enough is enough. This may well be the only way this hideously unfair practice is ended for good.

In traditional file systems we use df(1) to determine free space on partitions. We can also use du(1) to count the size of the files in the directory. But it’s different on ZFS and this is the most confusing thing EVER. I always forget which tool reports what disk space usage! Every time somebody asks me, I need to google it. For this reason I decided to document it here – for myself – because if I can’t remember it at least I will not need to google it, as it will be on my blog, but maybe you will also benefit from this blog post if you have the same problem or you are starting your journey with ZFS.

Since “Judge” Reyes is now a top military planner, she/they can report to Fort Benning at 0600 to instruct our Army Rangers on how to execute High Value Target Raids…after that, Commander Reyes can dispatch to Fort Bragg to train our Green Berets on counterinsurgency warfare.

In my view, the bottom line is that no one has an inherent right to serve in the Armed Forces. When the person suffers from a diagnosable mental illness and requires daily infusions of hormones and other drugs as well as surgery at government expense to live their best fantasy life, they shouldn't be allowed near weapons, ammunition, or explosives. From what we've seen of the impact of transgender "women" on women's athletic teams, you'd have to be a moron not to think they would have a much more deleterious effect while living in close quarters in barracks or deployed.

It is easy for Reyes to make the decisions she's made so far because she has never served in the military and will never have to live with the consequences of her actions.

The zfs list command provides an extensible mechanism for viewing and querying dataset information. Both basic and complex queries are explained in this section.

For one of my datasets zfs list and df show significantly different used numbers: //

Okay, zfs list -o space reveals that it’s (a) snapshot(s):

zfs list -t snapshot myPool/myDataset

For the life of me, I really don't understand why it is in our interests to fund research at foreign universities using federal funds. Research funding is a zero-sum affair. Doling out $386 million to Australian universities means that money will not be available for funding opportunities for American scientists or world-class scientists living in other countries who want to come to America. We should've learned the folly of pushing our research dollars into foreign universities where we can't control what goes on with our Wuhan Institute of Virology tragedy.

Recovering from measles does not protect against cancer or any other disease besides measles. In fact, a measles infection has the ability to wipe out immune responses built up against other infections—a phenomenon called immune amnesia, driven by the destruction of memory T- and B-cells. This leaves people who recover from the measles virus more vulnerable to all other germs.

This is not the only severe risk of measles. In addition to neurological and respiratory complications from measles infections, which can demonstrably turn deadly, measles can cause subacute sclerosing panencephalitis (SSPE), a fatal neurological condition that can flare seven to 10 years after a measles infection. //

Before the development of measles vaccines, the virus infected 3 to 4 million people each year, sending an estimated 48,000 to the hospital. About 1,000 developed brain swelling and 400 to 500 died.

Two doses of MMR vaccine are 97 percent effective against measles, and the protection is considered lifelong.
