r/btrfs

I've got my main desktop switched from Windows 10 to Arch with some subvolumes, Suse-like and snapper based. This is a single NVMe drive with the btrfs subvolumes living inside a LUKS partition. All subvolumes are mounted with the nodiscard option and I'm running fstrim weekly via a systemd timer.

So far I have encountered no issues, but I'm wondering how I should check the health of these subvolumes. Any advice would be appreciated.

I have used btrfs as my daily driver file system for a very long time. I have restored my system with snapper and snapshots numerous times through grub.

I have one issue though and it may just be me, but I feel that btrfs is very sensitive to every day mishaps like system freezes and hard reboots. It seems to me that it's much easier to get a more or less corrupted file system on my btrfs powered machines after a freeze or power outage than on my ext4 or even ntfs ones. Sometimes i am able to repair things but most often if there's some corruption it's not much I can do.

Is it just me or is btrfs more sensitive to hard reboots than other file systems?

I'm not a developer, just a Linux user since 1998 kind of guy so I ask here since I recently had my main laptop freeze beyond reproach and did a hard reboot. After that my monthly scrub has been complaining about corruption.
