<div dir="ltr"><div>Hi,</div><div><br></div><div>I'm running OpenVZ (OS container) kernel variant of RHEL6 kernel on</div><div>several amd64 machines by different manufacturers (HP and Supermicro)</div><div>and different RAID cards (HP and Areca).</div><div><br></div><div>I've started seeing kernel crashes in October, as per the netconsole</div><div>logs attached, on two of the machines (one HP, one Supermicro). The</div><div>traces look quite similar, the machine in question cannot write</div><div>anything to its own filesystem when this happens so the logs are made</div><div>over the network. The XFS filesystem is not root (that's ext4), but</div><div>one for data (OS containers), on both machines. When I run xfs_check</div><div>and xfs_repair on the filesystem after the kernel crash & reboot, no</div><div>issue is ever found.</div><div><br></div><div>This may very well have nothing to do with XFS kernel code you wrote</div><div>and maintain, but in that case, could you, from looking at the traces,</div><div>tell me whether it maybe looks like something issue related to</div><div>vm/paging just ending up in XFS related code path?</div><div><br></div><div>I'm happy to test any suggestions/fixes for this if it is XFS related.</div><div><br></div><div>Thank you,</div><div>-- <br></div>Jan Kokoska<br>Glow Internet s.r.o.<br>
