Hi, in my company laptop (Lenovo X220) I installed openSUSE 12.3 RC2 with btrfs then I updated to 12.3. I had an encrypted partition. The performance was very good at the beginning. But it became worse and worse over time due to my hardisk being busy for no reason. At some point I began to experience time slots up to one minute in which I my laptop got frozen and came back to life again like nothing happened. I thought it was due to Akonadi. So I deactivated it but problems remained. Ludwig Nussel checked it and determined that the source of the problem most likely was btrFS. I reinstalled my machine some days ago with ext4 and full hard disk encrypted and so far the laptop goes fine. Nothing different from BtrFS behavior at this point in time for me though. Please remember that I am not an engineer and my knowledge about the system is very limited. On Thursday 04 July 2013 11:54:05 Jeff Mahoney wrote:
Hi all -
Over the past year, btrfs has received substantial attention in the areas of both stability and performance. I've been running it, personally, on a 4 TB data volume as well as my root partitions for my openSUSE 12.2/12.3 systems. I've been able to do stress tests like a long fsmark run simultaneously with creating and removing snapshots (with syncs to force them to disk) and haven't run into any issues. David Sterba, who's been leading the charge at SUSE for btrfs stability has likewise regularly run it through an array of torture tests and has found that problems are occurring a whole lot less frequently than they have in the past. The upstream btrfs community in which we participate has also started focusing less on feature development and more on stability and performance.
But these are only anecdotal data points from two file system guys and if my experiences working for a major operating systems vendor have taught me anything, it's that our users can be a lot more creative at finding ways to break things than we are. ;)
So, I'd like to hear your stories. What's worked for you? What hasn't worked? What would you consider the pain points with using btrfs?
Lastly, I'd like to ask that you take the opportunity to test with the latest openSUSE Factory kernel running 3.10-final. 12.3 used the 3.7 kernel since it was the most recent release going into the beta cycle and we've seen a bunch of btrfs fixes since that release.
I look forward to your feedback and the opportunity to improve btrfs for the 13.1 release and future releases.
Thanks!
