Description

We had a few hundred clients all LBUG and then kernel panic on unmount of a lustre filesystem recently. All the ones that I checked have the same backtrace. See the attached sierra32_console.txt.

It looks like others have hit this in earlier 1.8 versions. See bugzilla.lustre.org bug 23861.

• Trackbacks: Lustre 1.8.x known issues tracker While testing against Lustre b18 branch, we would hit known bugs which were already reported in Lustre Bugzilla https://bugzilla.lustre.org/. In order to move away from relying on Bugzilla, we would create a JIRA
