From 4e54382989138155100a5cae90d70ca162dab703 Mon Sep 17 00:00:00 2001 From: Michael Polenchuk Date: Fri, 16 Feb 2018 13:20:41 +0400 Subject: Set nova disk cachemodes to file directsync Set nova/libvirt disk cache modes to file directsync to bypass the host page cache & prevent instance's kernel panic due to absent /dev partition. Caching mode directsync effectively turns all guest I/O operations into direct I/O operations on the host, which is the NFS client (virtuals) or GlusterFS (baremetals). Also return back to hwe kernel as a golden mean between GA & Edge ones.
