Hi, I just tried to setup a one-device raid onto an USB flash drive. Creating, setting up ext3 and filling with data was no problem. But when I tried to work with it afterwards the metadevice was unresponsive. I tried both linear and raid0 levels, but that made no difference. For my uneducated eye it looks like something is deadlocking if md tries to read from the device. I'm using kernel 2.6.18 (gentoo) on a VIA EPIA CN10000 mainboard with a 2GB USB flash drive (extreme). Please ask if I should provide more information like dmesg or lspci. The main reason why I'm trying this weird setup is that the USB drive is always enumerated last in my kernel, and I want to boot from it. That means every time I add a disk or remove one I have to edit grub.conf and fstab. Very inconvenient. So my idea was to create a single device md on it and leave it to the autodetection to find the device. So I never have to edit /etc/fstab again for a simple hardware change and I'm independent of any enumeration changes in future kernel releases. But unfortunately it doesn't work :-( Any help appreciated. --Arne - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
