[Kernel-packages] [Bug 1529146] Re: btrfs balance leads to kernel panic
Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of a regression, and when this regression was introduced. If this is a regression, we can perform a kernel bisect to identify the commit that introduced the problem. ** Changed in: linux (Ubuntu) Importance: Critical => High ** Also affects: linux (Ubuntu Wily) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Wily) Status: New => Triaged ** Changed in: linux (Ubuntu Wily) Importance: Undecided => High ** Tags added: kernel-da-key -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1529146 Title: btrfs balance leads to kernel panic Status in linux package in Ubuntu: Triaged Status in linux source package in Wily: Triaged Bug description: Running rebalance on a 3 drive btrfs volume with both data and metadata set to raid1 leads to a kernel panic.

[Kernel-packages] [Bug 1529146] Re: btrfs balance leads to kernel panic
Happens to me too any time I try a balance against either a single drive btrfs partition or a multi-drive btrfs partition. It will usually happen about 20% into the balance operation. I've been able to reproduce this on demand 6 times now.
