Issue | An RSA NetWitness appliance hangs at the "Probing EDD" step during the boot process. |
Resolution | If you are unable to get past the 'Probing EDD' screen you must do the following:
mount -o remount,rw / Once the root filesystem is mounted read-write, the /etc/rc.sysinit file must be edited to provide additional time for the RAID volumes to come online prior to LVM initializing. Currently, the sleep statement is set to 2 seconds but this value should be increased to 10 seconds. To do this, perform the following steps:
Here are the affected lines as they appear prior to editing: if [ -x /sbin/lvm ]; then sleep 2 action $"Setting up Logical Volume Management:" /sbin/lvm vgchange -a y --ignorelockingfailure fi Here is how they should appear after the edit: if [ -x /sbin/lvm ]; then sleep 10 action $"Setting up Logical Volume Management:" /sbin/lvm vgchange -a y --ignorelockingfailure fi |
Notes | It has been found that some appliances will hang on boot while at the "Probing EDD" message screen. This is due to the RAID volumes not coming online in time prior to LVM starting. Due to the fact that serial console redirection is turned on by default, if connected with a monitor and keyboard you will not be able to see where the OS boot is stalled at, but it is most likely unable to mount a filesystem on a RAID volume. |
