Hi,

What are your steps to upgrade ? Did you remove the old packages before upgrade ?
Let me show you steps to upgrade hopefully it will work.

1. Stop mysqld
2. Remove percona server packages.
3. Install new percona server packages.
4. Run mysql_upgrade
5. Start mysqld

To be on safe side you can take important database backup before upgrade. Look likes you didn’t stopped the mysqld before upgrade.

What are your steps to upgrade ?

I was running the upgrade via webmin and assuming that it would go through the sequence of steps correctly.

Look likes you didn’t stopped the mysqld before upgrade.

I focused on the error that says “two PID files”…so are you saying that 2 PID files is not the problem?

P.S. Sorry it took me a bit to reply…got no notification from these forums that someone has posted a reply to this topic…
