dear non-Patronizers: February's "See the Sausage Being Made" is now public. https://mwl.io/archives/24612

includes a reveal of the #openzfsmastery cover painting!

February’s Febrile Sausage – Michael W Lucas

"They cranked the OpenZFS version up to 5000, leaving Oracle plenty of space to add new version numbers--as if Oracle would EVER innovate rather than merely exploit acquired intellectual property." #nonotryagain #openzfsmastery
"Remember, happy filesystems are all alike; every unhappy filesystem is unhappy in its own way." #openzfsmastery

Ground out some words on #openzfsmastery today, discussing lopsided pools and self-healing. Also got tomorrow's #60SecondsOfWIP recorded!

I'd appreciate your help keeping the lights on while I finish this book. https://sponsor.mwl.io

I should replace this whole section with "make sure your filesystem blocks align with your disk's physical sectors or ZFS will GUT YOU LIKE THE SQUEALING PIGLET YOU ARE." #openzfsmastery

Today in #openzfsmastery: re-re-redrafted the section on block size, then discussed ashift autodetection, stripes, and mirrors.

Want to help me keep the lights on while I scribble this silly thing? https://sponsor.mwl.io

I got to use the word "pernicious" today, yay! #openzfsmastery

Finally getting back to my 72-disk draid bhyve VM for #openzfsmastery.

Turns out that setting ahci_device_limit="8" in the vm-bhyve config let it boot just fine.

Thank you everyone for your suggestions, but especially @dch for this one!

spent the day arguing with debian and bhyve. finally got to crack open the #openzfsmastery manuscript and discovered: my brain is done.

It's Friday. I'm gonna knock off a bit early, fold some laundry, do some dishes, and go to the dojo.

My boss is gonna hate it, but to hell with that guy.

Hey #freebsd #bhyve users!

I'm trying to test draid virtually for #openzfsmastery, because nobody's gonna give me a shelf of 60 disks to play with. I set everything up like:

disk35_name="disk35"
disk35_type="ahci-hd"
disk35_dev="sparse-zvol"

Seems that if I have 35 ahci-hd entries, disk0 through disk34, bhyve and freebsd works. At disk35, the host panics on boot.

Is this expected with bhyve? Or does FreeBSD need a special tweak with 36 disks?
