OK so Ronan, I'm gonna guess the simplest work around for your problem is to disable quota support, and see if the problem happens again. If it doesn't happen again then it sounds like the reproduce steps are: a. enable quota support b. do something metadata heavy workload that's also maybe hitting fsync; from opensuse list the example that sometimes causes it: osc co home:Ronis_BR/julia cd home:Ronis_BR/julia osc build --root=`pwd`/jail openSUSE_Tumbleweed x86_64 I wonder if it's easier to hit it on a hard drive, slower fsyncs? -- Chris Murphy -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
