FC5 not bootable (after installation) on RAID system
Last modified: 2007-11-30 17:11:39 EST
Description of problem: After installation of FC5 on a Compaq system fitted with a Compaq Smart Array 431, the system comes to a halt during it's first boot with the following message: ---------------------------------------- Checking filesystems fsck.ext3: Permission denied while trying to open /dev/ida!c0d0p2 You must have r/w access to the filesystem or be root ---------------------------------------- For your info: /dev/ida/c0d0p2 is a partion assigned as / Why there is a ! in the path I can't explain. Version-Release number of selected component (if applicable): Fedora Core 5 + SELinux enabled (default enabled during installation) How reproducible: As long as SELinux is enabled, no way to get passed the problem. Steps to solve it: 1. Booted the system with the first installation cd of CentOS4.3 (no SELinux!) 2. Manually edited /etc/fstab and set the checks to "0 0" on all /dev/ida/.. partitions 3. Reboot and the system will boot. 4. Disable SELinux and restore /etc/fstab. 5. System works without a flaw! Additional info: Although I did not test FC6t1, I expect SELinux to be enabled during installation by default in the coming release(s). Please, implement SELinux in FC6 in the same way as BEFORE FC5: disable SELinux and ask the user during the configuration at the first boot to enable it. After restoring /etc/fstab, I noticed not all /dev/ida/c0d0p1 - c0d0p7 partitions being displayed correctly. Although the system works, some are displayed still displayed as /dev/ida!c0d0p2 (as in the original crash message), but others are displayed as /dev/ida/c0d0pX
The problem here is that udev or something else is creating a badly named/labeled file. SELinux has no idea what this is so it ends up labeled device_t instead of fixed_disk_device_t.
Udev replaces '!' with a '/' and creates a subdir. I don't think it's udev who creates these nodes.
