Why automatically snapshot filesystems? Because snapshots let you magically fall back to older versions of files and even the operating system. Taking a manual snapshot before a system upgrade is laudable, but you need to easily recover files when everything goes bad. So I surveyed my Twitter followers to see what FreeBSD ZFS snapshot automation . . . → Read More: a survey of FreeBSD ZFS snapshot automation tools
You can now buy my next tech book, FreeBSD Mastery: Storage Essentials, for $7.99.
This is an incomplete book. It has not been tech reviewed. The advice in it might eat your disks and sell your soul to a Manhattan hot dog vendor for use as a dish cloth. So think of it as a . . . → Read More: FreeBSD Mastery: Storage Essentials – discount pre-pub available
Well, “profit” is a strong word. Maybe “not losing money” would be a better description. Perhaps even “not screwing over readers.”
I back up my personal stuff with a combination of snapshots, tarballs, rsync, and sneakernet. This is fine for my email and my personal web site. Chances are, if all four of my backup . . . → Read More: Installing and Using Tarsnap for Fun and Profit
My employer’s mail server runs DirectAdmin on FreeBSD, with ZFS. The mail server is important to the company. We want to be able to restore it quickly and easily. While we back it up regularly, having a “known good” base system with all the software installed, where we can restore the mail spools and account . . . → Read More: Cloning a FreeBSD/ZFS Machine with ‘zfs send’
I need to add drives to one of my FreeNAS 8.3.1 boxes. This machine has an “Intel RAID” card in it. I don’t want to use the Intel RAID, I want just a bunch of disks that I can plop a mirror on top of. The BIOS utility doesn’t give me the “just a bunch . . . → Read More: mfiutil on FreeBSD
A couple weeks ago, I monopolized the freebsd-hackers mailing list by asking a couple simple, innocent questions about managing disks using gpart(8) instead of the classic fdisk(8) and disklabel(8). This is my attempt to rationalize and summarize a small cup of the flood of information I received.
The FreeBSD kernel understands several different disk partitioning . . . → Read More: FreeBSD Disk Partitioning
I’m writing about FreeBSD disk and storage management. (The folks on my mailing list already knew this.) For the last few months, I’ve been trying to assimilate and internalize GEOM.
I’ve always used GEOM in a pretty straightforward: decide what I want to achieve, read a couple man pages, find an archived discussion where someone . . . → Read More: next book(s): FreeBSD storage
I didn’t see any public notes on this, so I decided to post it:
Google’s Compute Engine SDK installs and runs just fine on OpenBSD. Exactly as per the documentation. Which is what I’d expect, but it’s nice to confirm it.
Have a good weekend!
My Ansible host is OpenBSD. Because if I’m going to have a host that can manage my network, it needs to be ridiculously secure. The OpenBSD host runs on KVM (through the SolusVM virtualization management system).
During heavy data transfers, the network card would occasionally stop passing traffic. I could run any Ansible command without . . . → Read More: virtio NIC on OpenBSD 5.5-current
On Tuesday 27 May 2014, at 1pm EDT, I’ll be doing a live webcast on the O’Reilly community site.
The topic is “Beyond Security: Getting to Know OpenBSD’s Real Purpose.”
Anyone who has seen my mug.org talk already has an idea what angle I’ll take. Some of the slides will differ, and I’ll have some . . . → Read More: Live webcast on O’Reilly
