Re: btrfs on LVM: Out of space

2010/9/9 Zhu Yanhai [off-list ref]:

200B ~ 2000B is really too small to the modern hard disks (some of them
already have 4KB-sectors instead of 512B).

I know. But I thought that btrfs is the best FS for handling that.
Besides other storage methods than keeping small files on a
filesystem.
This is why I wanted to give it a try. It's currently just an
experiment for me to evaluate best practices.

Besides, currectly Btrfs doesn't play quite well with such small files, you may

had a patch for it, IIRC. Here it is:
http://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg05292.html
I don't know whether it has been in the kernel you are using.

Looking real quick on the patch and the git commits I would confirm
that this is already in the kernel 2.6.35 (which Ubuntu 10.10 uses).
So there is a good chance to have a "repaired" filesystem when I
recreate it.
