【Question Details】

1.       The Fusionserver RH1288 V3 quorum server's user password has been forgetten, the server is shut down after each startup.

2.       The quorum server keeps rebooting because of full log capacity.

【Solution Steps】                                                            

1      Modify Startup Parameters

1：Startup in the “kvm” interface, and enter “menu.lst” configuration interface.

2：Press ‘p’ and input the password ‘Huawei@123#’ or ‘Huawei@123’ (if wrong, use ‘Huawei@SYS3’), and press ‘Enter’ for entering the modify mode.

3：Press ‘e’ for entering the configuration modify mode.

4：Choose the ‘kernel’ line, and press ‘e’ again to modify this line’s configuration.

5：Add the ‘single’ to the end of this line.

6：Press ‘Enter’ to confirm your modify, and back to the following interface.

7： Press ‘b’ to startup the system.

2      Modify Password

1：When the startup finished, input the password ‘Huawei@123#’ (if wrong, use ‘Huawei@SYS3’) for entering the system.

2： Check whether you are in the following interface.

3： Modify the password for which account you want. (For example, the account is ‘QuorumAdmin’)

passwd QuorumAdmin

4： And recover the system (solving log capacity exhausting issue and password expired issue) as following command lists (you  can copy these commands and paste in the CLI to run together):

mount /dev/sda10

rm -rf /var/log/libvirt /var/libvirt

df -h #double confirm

rpm -e UVPHostd-1.0-131.x86_64

rpm -e qemu-kvm-2.3.0-B003

rpm -e libvirt-client-1.2.17-B153

chage -M 99999 quorumsvr

chage -l quorumsvr

df -h

echo “If you confirm all the commands execute successfully, then you can run ‘reboot’ now”

5： Double check before rebooting

chage -l quorumsvr #command to check the expiration setting of account

df -h #command to check the capacity usage of file systems.

Before removing, the /var/log/libvirt logs, the /var/log is almost full, after removing the logs, the capacity usage of /var/log decreases from 98% to 24%.

After erasing the unused packages of UVPHostd, qemu and libvirt, there will be no output of command rpm -qa | grep -E “UVPHostd|qemu|libvirt”

6： Reboot the quorum server to normally boot.
