BTRFS maintenance

[gilcon]

Hello good day,

Since the release of Pahvo, I’m planning to do a clean install and want to try the new GNOME 40.

But I have question about BTRFS, does the BTRFS maintenance is already take cared by Manjaro, or I still need to configure it?

Currently I’m using ext4 and I also want to try BTRFS.

BTRFS maintenance

What do you mean?

[gilcon]

I mean about scrubbing, balancing and defrag.
Something like this GitHub - kdave/btrfsmaintenance: Scripts for btrfs maintenance tasks like periodic scrub, balance, tri

I suppose it’s taken care of with the right options/packages (when applicable).

So we still need to configure it after install?
I was watching this from the Manjaro Pahvo | The Best GNOME Experience - YouTube
And just say a “enhanced support for BTRFS” and about the snapshot, but doesnt talk about the maintenance.

BTRFS does need little maintenance.

I do nothing regularly. Once in a time maybe a balance with limit 75% (after 3-6 month)

• If you are worried that the data on a btrfs volume has been corrupted, test it with btrfs scrub
• Please use btrfs balance sparingly. Most of the time it is unnecessary and only burdens the system. And if so, please always use it with limits (e.g. 75% or 50%)
• Take automatic snapshots (e.g. with snapper ). If possible every hour. With btrfs it doesn’t cost anything. Snapper can also automatically free these snapshots after a set time. (delete seems the wrong term here)
• If you have several (2, 3 or 4) devices and can combine them into one btrfs volume, then use RAID1
• Don’t forget to make good backups of your data. btrfs send is your friend

[Howto] rescue data from a damaged btrfs volume

Difficulty: ★★☆☆☆ You used btrfs. Now it’s paying off. There is an easy way out (I’ve already done this myself):

In most cases, when a btrfs volume breaks, it is possible to recover the data

This is because btrfs works with copy on write. This means that new changes are always appended at the end, so to speak. The previously existing data is not actually overwritten. (In reality this is a bit more complicated, but for us here this simplified view is sufficient). If the file system ge…

What does your btrfs balance command look like?
