* Traversing XFS mounted VM puts process in D state @ 2017-12-08 1:16 Dinesh Pathak 0 siblings, 0 replies; 4+ messages in thread From: Dinesh Pathak @ 2017-12-08 1:16 UTC (permalink / raw) To: linux-kernel Hi, We are mounting and traversing one backup of a VM with XFS filesystem. Sometimes during traversing, the process goes into D state and can not be killed. Eventually system needs to IPMI rebooted. This happens once in 100 times. This VM backup is kept on NFS storage. So we first do NFS mounting. Then do loopback mount of the partition which contain XFS. After that we traverse the file system, but this traversing is not necessarily multi threaded (We have seen the issue in both single-threaded and multi-threaded traversal) I see a similar problem reported here: https://access.redhat.com/solutions/2456711 The resolution given here is to upgrade the linux kernel to kernel-3.10.0-514.el7 RHSA-2016-2574 RHEL7.3. Upgrading the kernel may not be possible for us. Is there any patch/patches that we can apply to fix this issue. One more thread here says that this issue is fixed only in the above kernel version. It is seen in previous as well as later versions. https://bugs.centos.org/view.php?id=13843&history=1 Is there anyway to reproduce this problem. All our efforts to reproduce this issue have not succeeded. Please help me know if any more debugging can be done.
