It is nice to be able to move a VM from #FreeBSD to :omnios: #Omnios in a snap using the network just because they both ship with #ZFS and #bhyve. It nearly feels like vMotion.
Always nice to wake up to a "Drive failure expected in less than 24 hours. SAVE ALL DATA" cron alert...

(as opposed to actively scammy boards with firmware to make two random micro SD cards from the failed bin hot glued in place pretend a capacity in the TB range)
I actually thought "but how to I expose the individual cards to #zfs ?" before closing the page and waving a fork in the air near my eyeballs)
After over a week of trying to figure out why the fuck I couldn't access my #zfs pool from inside a #docker container, I finally found the solution.
It turns out that if you install docker from the ubuntu install screen (which installs via snap), the bind permissions are completely incompatible with zfs.
Once I uninstalled docker from snap and reinstalled from apt, the problem went away.
Geeeeeee, so rclone syncing into an encrypted remote can make file names so long that they exceed the file system's limit! The original isn't even that long.
So I'm using #ZFS on #TrueNAS and today I noticed that "auto-trim" is turned off on my ZFS pool. "Hmm," I asked myself "what is TRIM on ZFS?"
After a few minutes of searching, I have no idea what TRIMming does. I know a hundred ways to do "it" manually or automatically. But I don't know what it DOES.
So I finally found this presentation from 2019 that pretty well lays out what it is and why it exists. My drives, however, are rotating magnetic drives (just like in Victorian times), so I'm not sure there's any value in TRIMming my ZFS. Thoughts?
Patching #ZFS kernel module's license info to be able to get back to my files, as the #Linux kernel blocked non-GPL access to some of the previously used functions - and while following up on that, seems like #ArchLinuxARM might be sickly?
Seems like their package sources are unreachable ("internal error"), while the kernel stuck at a version from close to a year ago...
Gonna have to switch distros?
@technotim is back with @adam to discuss the state of homelab in 2024 🧑🔬
They discuss homelab environments providing a safe place for experimentation and learning, network improvement as a gateway to homelab, trends in network connection speeds, to Unifi or not, storage trends, ZFS configurations, TrueNAS, cameras, home automation, connectivity, routers, pfSense, and more.
This time a short one, I'm presenting my small weekend project, a NAS running ZFS on a Raspberry Pi Zero. The idea was to have a RAID1 mirror using two USB drives, but that did not turn out so well. But hey, it's the journey that matters. And it's running ZFS so it's serious stuff.
My 13 year old HP Microserver N40L finally died. Luckily, I had a new (8 year old) Gen8 one standing by. Moved the HDDs, did a ZFS import, and up we go! Thank you, #ZFS! #SunMicrosystems#Ubuntu
In week 2 of my #SysAdmin class, we're talking about storage models and disks: DAS, NAS, SAN, Cloud storage, disk interfaces, #RAID, LVM, #ZFS, physical disks, and partition types and tables.
The exercises include spinning up #AWS#EC2 instances and filling up disk space, using up all inodes, and moving an EBS volume across different instances and OS.
has anyone first hand experience with using live #zfs snapshots of #postgres? what i read seems to confirm that postgres should just start right up like it was recovering from a crash. what i worry about a bit is a quite large and high traffic database thats currently being handled by pgbackrest (which even for diff backups is quite slow).
currently considering something like ZnapZend :think_bread:
background being two dead ssd raids after reboot in a row.
Will those voices in my head please give it a rest !
Tempting to try a #VoidLinux#bcachefs install on an old laptop or pc now it's officially made it into the Linux 6.7 kernel. You know just for research purposes you understand. Like seeing how it compares to my daily drivers #ZFS filesystem. 🤔
