Well said. Linux is a treasure for mankind. Mars is not the end of its journey with human but only a new beginning. Looking forward to where it can take us to in the next 30 years #30YearsOfLinux #LinusTorvalds

OpenZFS on Linux is great (agree that it's more mature and business grade solution), however, relying on DKMesS (non Ubuntu) to rebuild modules after each kernel upgrade isn't that pleasant. The best tool is the one that does what you need at the best cost, choose wisely ;-)
Good points raised by @2_5adm1ns Ep 12 @OpenZFS @btrfs with scheduled snapshots provide a rollback mechanism to painlessly deal with ransomware. Obviously snapshot's "go back in time" ability has a lot more to offer, take snapshots folks ;-)
Deploying @btrfs at Facebook at scale by @josefbacik youtu.be/U7gXR2L05IU
The "Managing the @btrfs File System" chapter in Oracle Linux 8 Docs is NOT bad, in fact a quite good quickstart guide for noobs ;-) docs.oracle.com/en/operating-s…
Butter FS - Chris Mason & Avi Miller pronounced that way a lot when the former worked for Oracle (latter still does) in the early days, later on widely adopted in talks and popular podcast shows from @LinuxUnplugged @LinuxActionNews @SelfHostedShow @DestLinuxPod @2_5adm1ns etc.

Very good points raised in the @SelfHostedShow Ep 25 by Jon from @UnraidOfficial @btrfs is perfect for self-hosted home consumer grade storage solutions with mixed spec HDDs using old PCs, as long as users know what to use & when to avoid its raid{5,6} Read the Btrfs Wiki ;-)
Btrfs now has a status page btrfs.wiki.kernel.org/index.php/Stat…
Be aware of Btrfs raid5/6 serious data-loss bugs btrfs.wiki.kernel.org/index.php/RAID… Consider using ZFS on Linux before the bugs are fixed.
New tree-based space cached added to Btrfs by Facebook to improve perf during commits on large FS (30TB+), mount with space_cache=v2 ;-D
#Btrfs inband / online deduplication - dedup done in the write path (processes write data) is NOT supported yet. It'll eat RAM when ready;-D
Oracle UEK R4 (mainline 4.1.12 based) added Btrfs RAID 5, 6 support, snapshot-aware defrag, offline deduplication by dedup or duperemove 1/2
Linux 4.0 adds code to Btrfs inode struct to hold the file creation time.
Oracle Linux 7.1 offers Production support for Btrfs with its UEK Release 3 (kernel-uek-3.8.13-55.1.5.el7uek.x86_64) goo.gl/VeLLkS
Linux 3.19 added support for #Btrfs scrubbing and fast device replacement in RAID 5 and 6.
With SUSE Linux Enterprise 12 #Btrfs is the default file system for / while xfs is the default for all other use cases. Enjoy snapper.io ;-D
New #Btrfs changes in Linux 3.14 1. inode properties 2. new mount options 3. Publish internal info under /sys/fs/btrfs some can be changed
