No problem for installation, but after installation you have to create a particular initrd.You can read a good document here at http://www.simonf.com/usb/ and I have also a document written by John Austin (I do not remember where he posted this document!!!)
I understand that your disk is not recognized when hooked.What is the output of lsusb???
Hi Antonio
Thanks for the information. In fact I just found the document of simonf after some googling. I will try it later today.
In the mean time i will make an update of this issue:
I was able last night to install to the external USB Hard Disk by following the instructions of the "RFE: Add USB install support" from Bernd Bartmann at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=151690
The instructions and my results (MR) were:
1. enter "linux expert" at the syslinux prompt (expert is important because the USB storage devices are only available in disk-druid in this install mode)
--- MR: OK
2. you should now be able to partition the USB storage device as you like
and
3. install as usual but switch to Console #2 before the final reboot
--- MR: I just started the installation and partitioned the disk as --- usual. I tried both manual and automatic partitioning (with and --- without manually changing the automatic partition settings). Every --- time I went over this process a pop up window came lots of times --- complaining about several functions failing (example: Assertion ((c --- * heads + h) * sectors + s == a) at disk_dos.c:494 in function --- probe_partition_for_geom() failed).
--- MR: Every time this error window was shown I just clicked "continue" --- and every time the installation just continued and at last it ended --- (apparently ok).
--- MR: Some times I selected GRUB to be installed to MBR and sometimes --- I selected it to be installed to root. Again, installation process --- finished apparently ok every time.
--- MR: I was not able to switch to console #2, I think this was because --- I installed in graphical mode but not sure if this is the cause.
--- MR: Anyway I created a rescue CD (from iso found in setup CD as --- C:\xx\fedora3\images\rescuecd.iso) and after boot the rescue cd --- found the installation made to USB disk and mounted it to --- /mnt/sysimage, so I just ignored next step (step 4).
4. chroot /mnt/sysimage
--- MR: Ignored this step in my case, read previous step results.
5. mkinitrd --preload=ehci-hcd --preload=usb-storage --preload=scsi_mod --preload=sd_mod /boot/usbinitrd.img 2.6.11-1.1177_FC4
--- MR: OK. I just changed the kernel version from 2.6.11-1.1177_FC4 to --- 2.6.9-1.667 (FC kernel version of my FC installation).
6. edit /boot/grub/grub.conf to use the new initrd
--- MR: I did not found grub.conf at this directory. It might be somewhere else and/or with other name. Or maybe grub uses a different file name/format on FC3. I will investigate this later today.
7. Reboot
--- MR: Of course, my system wont booted. I tries to boot but displays --- some errors. I will manually copy these error messages and send --- another post later to see if somebody knows the answer.
(8.) This seems to be a bug:
When system booted it found my CF card but could not mount / although the e2label was created during installation. So I changed root=LABEL=/ to root=/dev/sda1 in grub.conf and was finally able to successfully boot from my CF card.
--- MR: I haven't checked this.
Conclusions:
I was able to install FC3 to my external USB Hard Disk. Partition and some installation steps showed lots of errors but it apparently finished ok as I was able to "boot" to this installation by chrooting it with the rescue CD.
I was not able to complete Mr. Bartmann's steps because grub.conf was not in the pointed directory. My installation can't boot by itself.
Next steps:
- Locate grub.conf or check if grub is configured somewhere/somehow else in FC3 and try to finish Mr. Bartmann's steps.
- Try and/or adapt Mr. Simon's steps.
- Try to create a bootable "disk" in my USB memory card with grub or lilo and boot from there (my laptop lacks of Diskette Drive).
- Try to create a bootable MBR (master boot manager) "disk" in my USB memory card and boot from there (my laptop lacks of Diskette Drive).
I'll keep you posted.
Anybody have more information?
Regards and thanks again.
