I have a set of servers i built then i have a set of servers that were here before me.
Same release level of Centos 7
Same bios
same Config for the most part.
When i updated the kernel on a server i built, i have no issue. it boots up fine.
When i update the kernel on a server that was built before mine, i get into the Dracut shell with the below errors. if i switch back to the old kernel, it boots up fine as well.
- ive tried rebuilding the initramfs for the new kernel, same result.dracut-initqueue[565]: Warning: could not boot.
dracut-initqueue[565]: Warning: /dev/centos/root does not exist

You might want to save "/run/initramfs/rdsosreport.txt" to a USB stick or /boot after mounting them and attach it to a bug report.
dracut:/#
-tried running lvm vgscan and i get nothing returned besides the message stating it may take awhile to scan then it instantly moves down to the next line of "dracut:/#" while returning no results.
-ive compared the two lvm.conf files to see if there was any difference at all and i could not locate any.
anyone have any other ideas of what to try or look into?
something else to note, when i ran the dracut -f to rebuild the initramfs i got the below error.
but when i navigate to that directory i see files in there all named modules.xxx.Kernel version initramfs-3.10.0-862.11.6.el7.x86_64.img has no module directory /lib/modules/initramfs-3.10.0-862.11.6.el7.x86_64.img
