Backup

I am trying to do a backup. In my script I stop the service first. Then I am trying to do an mysqldump as per the below:

/usr/clearos/sandbox/usr/bin/mysqldump -u zarafa -p -v --single-transaction zarafa | gzip > /var/tmp/zarafadump.sql.gz
With this I get

Enter password: -- Connecting to localhost...
mysqldump: Got error: 1045: "Access denied for user 'zarafa'@'localhost' (using password: NO)" when trying to connect

If I do:
/usr/clearos/sandbox/usr/bin/mysqldump -uzarafa -pPassword -v --single-transaction zarafa | gzip > /var/tmp/zarafadump.sql.gz
mysqldump: Got error: 1045: "Access denied for user 'zarafa'@'localhost' (using password: YES)" when trying to connect

What am I doing wrong

Thanks for the reply. To answer some questions: I am running Clearos 7 Home edition. For clarity, I can install the kernel. When I do a....... yum list installed kernel .........after I install it the kernel appears with the old kernel as the primary operating kernel. The issue I encounter is booting with this kernel. My current kernel and setup is using legacy boot. Does this change any of your response

Kernel Upgrade Issue 3.10.0-957.21.3.v7

I am having issue upgrading to the above kernel. The current kernel is 3.10.0-327.3.1.e17. The kernel appears to install however the server will not boot. It appears in the selection on start up but fails to load. Do I need to do anything in particular. I have tried several time to reinstall and reload
After removing the kernel
rpm -qa | grep ^kernel | sort
kernel-3.10.0-327.3.1.e17.x86_64
