Message-ID: <4FD1918A.2060908@gmail.com> Date: Fri, 08 Jun 2012 15:45:46 +1000 From: Jason Stubbs <jasonbstubbs@...il.com> To: linux-kernel@...r.kernel.org, xen-devel@...ts.xen.org Subject: PROBLEM: Possible race between xen, md, dm and/or xfs Hi, To quickly summarize, on a Xen domU instance with a disk structure of XFS on LVM2 on RAID10 on 8x virtual disks, all tasks performing I/O to said XFS partition hung and I cannot prove or disprove it to be dom0 issue. And now the long(er) version: On an Amazon EC2 (xen) instance, I had I/O to one of the EBS (Elastic Block Store virtual disk) devices block with iostat showing one single request pending. Kernel logs showed hung tasks so after grabbing those I reset the instance but - while I'm told that Amazon's logs don't show any problems with the EBS - Amazon want the opportunity to exclude an EBS problem by examining things from the dom0 side while the problem is occurring before delving into the kernel. So what I'm really hoping for is for somebody to take a look at the call stacks of the hung tasks and rule in/out a race condition. The kernel is linux-2.6.35.14-106.53.amzn1 but I've resolved the call stack to the source using gdb "list *(...)" as described in http://ds9a.nl/symoops.html. If it's needed, I'll send the relevant parts (or all of it) in a separate mail as it'll make this one too big. I'm sending to xen-devel as I'd think XFS on LVM2 on RAID10 would be not so uncommon, so I'd say Xen has something to do with it if there is in fact a race condition. I think that covers everything. Thanks in advance to anybody who takes the time to glance at this. Please ensure my mail address is included in replies as I am not subscribed. Firstly, the hung task information: INFO: task md127_raid10:967 blocked for more than 120 seconds.
