Subject: Re: Btrfs progs release 6.16.1
Date: Sun, 21 Sep 2025 14:25:34 -0400	[thread overview]
Message-ID: <a529e1bd-49c2-4463-90fe-847dd2c128f7@app.fastmail.com> (raw)
In-Reply-To: <eaf33285-5d77-4b7e-851a-61e40e61d3ae@harmstone.com>

I resolved it with a single command: 
mount -o clear_cache,space-cache=v2 /dev/dm-1 /mnt

clear_cache alone doesn't resolve it because a subsequent mount creates a v1 cache by default (kernel 6.17.0-0.rc6.49.fc43.x86_64)

My question is if it makes sense for the kernel to be capable of, by default, fixing problems like this? Future feature?

For now though, the `btrfs check` message lacks an indication of the (un)seriousness of the problem, or what the user should do about it. Maybe this message could be prefaced with INFO: ? to suggest it's just an informational level concern? 

The problem with the message and documentation is users are being advised to ask a btrfs developer or expert what to do about this message. So I kinda expect there will be messages on this list from users asking about it.
