Oracle VM: root (/) or /boot Filesystems Go Read-Only when a Path Fails on Multipathed LUN (Doc ID 1215384.1)

Last updated on AUGUST 04, 2018

Applies to:

Oracle VM - Version: 2.1 and later   [Release: OVM21 and later ]
Generic Linux
***Checked for relevance on 25-Mar-2012***

Symptoms

Oracle VM Server installed in a multipathed LUN (/boot, / and swap). When a specific SAN cable is detached the /boot filesystem (and sometimes the root filesystem at /) becomes read-only. It may also lead to system hangs or unconditional reboots.

The cables, SAN and HBAs  are working properly. So it is confirmed that nothing is wrong with them.

Changes

New installation.
