I had a similar problem with a new usb disk under centos5: the disk (sdb) was not listed under /dev/disk/by-uuid. I had to create the symlink there manually: [root at xen by-uuid]# udevinfo -q all -n sdb P: /block/sdb N: sdb S: disk/by-id/usb-WD_Ext_HDD_1021_574343305330343332373736 [root at xen by-uuid]# ln -s ../../sdb1 usb-WD_Ext_HDD_1021_574343305330343332373736 After that everything worked fine. I have no idea if what I did was somehow wrong and what will happen after next reboot, but the server has been running just fine for months after that operation. Regards, Peter
