Short nfs failure on 3.9.2019

We have seen the /nfs mount beeing unavailable on the SC cluster nodes on Galaxy, Sirius and Polaris on 3.9.2019 from about 17:20 until 17:45. You probably want to check your jobs running during this.

Maybe the problem was caused due to high metadata load on the nfs directory. We are sorry for any inconveniences.
