Chapter 5 Notes and RestrictionsMessages written to syslog when multiple mirror disk resources orhybrid disk resources are usedWhen more than two mirror disk resources or hybrid disk resources are configured on a cluster, thefollowing messages may be written to the OS message files when the resources are activated.This occurs by a fsck command function (function to access a device block which is not a targetof fsck) on some distributions.kernel: [I] NMPx I/O port has beenclosed, mount(0), io(0).kernel: [I] - This message can berecorded by fsck command when NMPx becomes active.kernel: [I] - This message can berecorded on hotplug service starting when NMPx is not active.kernel: [I] - Ignore this and followingmessages 'Buffer I/O error on device NMPx' on such environment.kernel: Buffer I/O error on device /dev/NMPx, logical block xxxxkernel: NMPx I/O port is close,mount(0), io(0).kernel: Buffer I/O error on device /dev/NMPx, logical block xxxxIPMI messageThis is not a problem for ExpressCluster. If this causes any problem such as heavy use of messagefiles, change the following settings of mirror disk resources or hybrid disk resources.- Select “Not Execute” on “fsck action before mount”- Select “Execute” on “fsck Action When Mount Failed”When you are using ipmi for user mode monitor resources, the following kernel module warninglog is recorded many times in the syslog.modprobe: modprobe: Can`t locate module char-major-10-173When you want to prevent this log from being recorded, rename /dev/ipmikcs.138ExpressCluster X 3.1 for Linux Getting Started Guide
