Hi, i'm using centos with dm-multipath and iscsi as a database system. All packages are normal centos packages from their mirrors.
This night I was updating centos to the current release (5.3, previous version was 5.2). So the first thing I have done was stopping the multipathd and iscsi. After this I was doing the normal update stuff (yum check-updates, yum clean all, yum update glibc\*, yum update). During the last yum update the new kernel was installed (2.6.18-128.1.6.el5, previous was 2.6.18-92.1.22.el5). During the installation process of the kernel, the yum process hangs. Looking with ps for the hanging processes, I see that the kernel package was building the initrd. After killing this process and repeating the yum update process (this time only the kernel-package) about 5 times, the same strange failure occurs (process hangs on building initrd). The sixth time I was stracing the whole update process and see that the mkinitrd process does a wait-syscall for sth.. After killing this process again I went down to the server room to reboot the system and try another update process. I reboot the systems, stops multipathd and iscsi and starting the update process. On this update I could see that during the mkinitrd process, a kernel message "device-mapper: failed path x:x:x:x" occurs. Hmm this is strange I thought, because I've stopped multipathd and iscsi, so why means the kernel that a path is failed? Once again killing the mkinitrd process and then starting multipathd and iscsi I've tried another update process. And, yeha, it works??? I could reproduce this behavior on 2 machines, both centos with standard packages. So can anybody comprehend this "failure" or any ideas?
