Is Btrfs in 10.10 considered stable?
I've done a bit of googling about this since asking the question and found:
- there is currently no fsck for btrfs (as of linux kernel 2.6.36, while maverick has 2.6.35), so "it's rather easy to kill a btrfs by just losing power".
- the btrfs launchpad blueprint has the comment " I deferred this for completion in Natty, as we won't be able to complete all the remaining work for Maverick".
- there is an open bug about dpkg upgrades and installs being very slow on btrfs.
So all these would suggest btrfs should not be used on a production system, or any other system where you care about the data.
It is not considered stable.
People are usually conservative when it comes to new filesystems. You don't want to lose data, right?
If your data under /home is not important to you, brtfs is a good fs choice right now.
