This is driving me crazy since hours now. I have done the setup of 5 instances in AWS (some micro, some large) and after a while when i stopped them and rebooted them many times one of them won't boot.
I digged the problem to the point where when dracut start and try to switch the root filesystem there is some errors with the disk mapping and the /dev/xvd* devices.
Logs from a working one :
udev: starting version 147 dracut: Starting plymouth daemon xlblk_init: register_blkdev major: 202 blkfront: xvde1: barriers disabled Changing capacity of (202, 65) to 14680064 sectors xvde1: detected capacity change from 0 to 7516192768 EXT4-fs (xvde1): mounted filesystem with ordered data mode. Opts: dracut: Mounted root filesystem /dev/xvde1 dracut: Loading SELinux policy
Logs from a non working one :
udev: starting version 147 dracut: Starting plymouth daemon xlblk_init: register_blkdev major: 202 blkfront: xvde1: barriers disabled EXT4-fs (xvde1): mounted filesystem with ordered data mode. Opts: dracut: Mounted root filesystem /dev/xvde1 dracut: Loading SELinux policy
I have tried to delete /etc/blkid/* but without luck.
If someone could help me on this i would be very thankfull
