Unable to boot with LVM mount on USB drive (Fedora 10)

[Bruce Thompson]

Hi all,

I haven't seen this reported anywhere else and it's kind of driving me  
nuts.

I've got an LVM volume group that extends across two internal drives  
and one external USB drive. Prior to Fedora 10, the volume group  
initializes fine during boot and the filesystems listed in /etc/fstab  
mount fine. As of Fedora 10, the initialization of the volume group  
fails apparently because the USB drive is not yet registered when LVM  
attempts to bring up the volume group.

I have a workaround, namely the following in rc.local:

vgchange -ay Backups
mount -o defaults,noatime /dev/Backups/Backup /backup
mount -o defaults,noatime /dev/Backups/Staging /staging

Obviously this is non-optimal since it bypasses the automatic fsck step.

Heres the relevant bit from /var/log/boot.log:

In /var/log/messages I see that the external drive (sde) is attached  
immediately prior to filesystems being mounted but I can't tell from  
that whether LVM initialization occurs before or after USB Mass  
Storage comes up.

Has anyone else encountered this? Is there a known workaround? I did  
see the thread on fedoraforum regarding SCSI boot problems but it  
appears to me that these are not the same issue.

Thanks much!
Bruce.
