Dear btrfs experts,
I hope this is the correct place to ask, the wiki and manpages did not help me on these questions.
BTRFS has gained extended inode refs, skinny metadata and no-holes quite a while ago and these are now the defaults for new mkfs.btrfs. btrfstune can activate those features.
However, I miss two things:
- How do I see on an existing FS which of these features are on?
btrfstune (it seems) can only "set", but not "get" the feature flags.
- Is it worthwhile / recommended / safe to activate those on existing FS?
Are there any steps (e.g. balancing metadata with -musage=0, I'd guess) needed to make them become active afterwards?
If there is any documentation on this and I missed it, please RTFM me.
Cheers and thanks a lot,
Oliver
