Hi, I just deleted all old partitions, created new partitions and installed a fresh FC4 system. The installation did not show any error. After the installation, I reboot it. During the booting process, I saw an error message after "Setting hostname xxx: [OK]" as: Setting up Logical Volume Management: /var/lock mkdir failed, read-only filesystem Then, other booting processes pass through. Now, the system is running, I can access it using ssh, httpd is working. However, when I start dovecot (I did not change /etc/dovecot.conf), it failed: # /etc/init.d/dovecot start Starting Dovecot Imap: [FAILED] I turn the service dovecot on, then reboot. I saw the error message as above and the new error: Starting service dovecot failed: can't use SSL certificate ... /etc/pki/dovecot/dovecot.pem permission denied (it went through so fast that I can't catch all the words). If I start dovecot manually, it is ok: # /usr/sbin/dovecot # ps xa | grep dov 2622 ? Ss 0:00 /usr/sbin/dovecot 2624 ? S 0:00 dovecot-auth The system logs don't show anything related to dovecot, nor the message ".../var/lock mkdir failed..." I update the kernel from 2.6.11-1.1369_FC4 to 2.6.12-1.1447_FC4, reboot, but got the same error messages as before. Can somebody tell me what's wrong with the installation and the system? Are the above two error messages related each other? Will the error "/var/lock mkdir failed" cause any other problems? If I turn off selinux, then I can start service dovecot: # setenforce 0 # /etc/init.d/dovecot start Starting Dovecot Imap: [ OK ] and it creates an entry /var/lock/subsys/dovecot. However, when I reboot the system, the same problems and errors show up again. It seems that it is related to selinux. I am using targeted, enforcing selinux and has the policy selinux-policy-targeted-1.23.16-6 installed from the FC4 CDs. How to solve the problem? Thanks a LOT! Hongwei Li
