**The Filesystem Diaries: Scaling Btrfs in an Enterprise**
|
||
|
||
Btrfs was merged into the Linux kernel in 2009, arriving with bold
|
||
promises—and, let's be honest, a reputation for instability. I first tried it
|
||
on my laptop in 2011. It wiped my data. Twice. On the bright side, it taught me
|
||
the value of backups.
|
||
|
||
Fast forward to 2025: btrfs is no longer the experimental filesystem of the
|
||
past. It's stable, mature, feature-rich, and fully part of the Linux kernel.
|
||
But old reputations die hard. Even today, Google Cloud Platform doesn’t
|
||
officially support it—not because of technical shortcomings, but because
|
||
customer demand hasn’t pushed the issue.
|
||
|
||
At Chronosphere, we decided to take a fresh look. After months of evaluation
|
||
and testing, we migrated petabytes of customer data across thousands of disks
|
||
to btrfs. This talk is our story: why we made the leap, what we learned along
|
||
the way, and how we’re helping bring btrfs into wider enterprise
|
||
adoption—including working with Google to support it natively.
|
||
|
||
I'll share the decision-making process, key performance and reliability
|
||
insights, and the quirks you only discover when running btrfs at scale. Whether
|
||
you're btrfs-curious or just love a good ops tale, you'll walk away with
|
||
real-world takeaways—and maybe a newfound respect for this once-maligned
|
||
filesystem.
|
||
|
||
If you know what NTFS, ext4, or ZFS are, you’re ready for this journey.
