Core will be in ftp://shell.sgi.com/collect/lu4224 within an hour and should remain for a week.

This is using "lastSuccessfulBuild" on 2013.11.06.

My own builds have not had this problem, but there are two notable differences:
1) The last build I tested was a pull from about a week ago.
2) I have been building both server and client against the SuSE provided default kernel.

On a side note: Does automated testing for sles11sp[23] exist? If so, is there an easy way to check the test reports? I noticed that even SLES specific changes (ie http://review.whamcloud.com/#/c/7752/) are tested against CentOS.

Hello Stephen,
Is there any further work required on this ticket from 2013?

Many thanks,
~ jfc.

If you are actively testing sles11sp3 servers with ldiskfs, then this must be resolved.

Good news indeed – thank you for letting us know this Stephen.
Best regards,
