Hi all, I know it's a decade-old question, but I'd like to hear your thoughts of today. By now, I became a heavy BTRFS user. Almost everywhere I use BTRFS, except in situations when it is obvious there is no benefit (e.g. /var/log, /boot). At home, all my desktop, laptop and server computers are mainly running on BTRFS with only a few file systems on ext4. I even installed BTRFS in corporate productive systems (in those cases, the systems were mainly on ext4; but there were some specific file systems those exploited BTRFS features). But there is still one question that I can't get over: if you store a database (e.g. MySQL), would you prefer having a BTRFS volume mounted with nodatacow, or would you just simply use ext4? I know that with nodatacow, I take away most of the benefits of BTRFS (those are actually hurting database performance – the exact CoW nature that is elsewhere a blessing, with databases it's a drawback). But are there any advantages of still sticking to BTRFS for a database albeit CoW is disabled, or should I just return to the old and reliable ext4 for those applications?
