Testing btrfs compress option

https://bbs.archlinux.org – When using the compress mount option, there's usually a message in dmesg with btrfs recognizing that compression is enabled.I guess one way to confirm compression is enabled is to do something likedd if=/dev/zero of=file bs=1M count=1024 btrfs fi sync /btrfsmountpoint du -h file then check the file size.Also, I think it should be lzo and not Lzo. I'm not sure if it's case sensitive. And AFAIK lzo is now default compression algorithm in btrfs, so =lzo shouldn't be needed. Furthermore, if your HDD is REALLY abysmal as you say, you can try using zlib instead of lzo as it has h (HowTos)
