That's my understanding too, except in one of the scenarios I observed 100% SYS CPU for long stretches even when there was a significant amount (~50GB) of the device unused.
However, if it was a soft lockup it was for >8 hours, during which the machine was totally unresponsive to HTTP requests, which amounts to a very dead production machine. In the end I'm not sure what to do about all of this. I'm surprised to find out that BTRFS can back itself into a corner from which it cannot retrieve itself. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1349711 Title: Machine lockup in btrfs-transaction To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1349711/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
