Booting CD, /usr not found

[BarryK]

No unfortunately, the tcl/tk libs are in /usr/lib, in the usr_cram.fs file.

[BarryK]

Okay, in an rxvt terminal you type:

# disktype /dev/hdg

I would like to know the exact error message returned -- just drag the mouse pointer over the message to highlight the text and it will automatically go into the clipboard when you release the left mouse button -- then ctrl-v to paste it into this forum.

Also try this:

# probepart

...if this works, what i could do is modify the bootup code so if disktype returns error msg, then use probepart.

Although you have worked around the problem i would like to solve the original problem!

Jonathon,
where are you?!!
I'm keen to get feedback on this.

[Guest]

In my case I have
# disktype /dev/hdc

--- /dev/hdc
Block device, size 60.42 MiB (63358976 bytes)
CD-ROM, 1 track, CDDB disk ID 00000001
Track 1: Data track, 0 bytes

# probepart
ext3
ext3
/dev/hdc|iso9660|0|VMware Virtual IDE CDROM Drive
/dev/hda1|ext3|4016187|Linux Ext3FS
/dev/hda2|swap|803250|Linux Swap
/dev/hda3|ext3|3566430|Linux Ext3FS
#

Note that the 'CD' is a VMware virtual CD, mapped to the .iso file (as opposed to a virtual CD mapped to a real drive)

I had to type the above data in, so there might be typos.

[BarryK]

Thanks for the response.
That is very interesting. In my case, with a real CD drive:

Code: Select all

# disktype /dev/hdc

--- /dev/hdc
Block device, size 60.35 MiB (63277056 bytes)
CD-ROM, 1 track, CDDB disk ID 02019B01
Track 1: Data track, 60.35 MiB (63277056 bytes)
  ISO9660 file system
    Volume name "CDROM"
    Application "MKISOFS ISO 9660/HFS FILESYSTEM BUILDER & CDRECORD CD-R/DVD CREATOR (C) 1993 E.YOUNGDALE (C) 1997 J.PEARSON/J.SCHILLING"
    Data size 60.31 MiB (63242240 bytes, 30880 blocks of 2 KiB)
    El Torito boot record, catalog at 32
      Bootable non-emulated image, starts at 33, preloads 2 KiB
        ISOLINUX boot code
    Joliet extension, volume name "CDROM"

The rc.sysinit boot script looks for that string "ISO9660", but in your case it ain't there. Hence failure.
But, probepart does report "iso9660", so I will modify rc.sysinit to use that as a fallback test.

...or, did you just not type in the entire response from disktype?

Bye the way, you don't have to type it in.
From a rxvt terminal, drag mouse pointer over text to highlight it, release mouse button, text is automatically placed in clipboard. ctrl-v to paste it.

[Guest]

That was the entire response from disktype. The track shows as 0 bytes, so I suppose it can't look to see if there is a file system there. Possibly a problem in the vmware cd emulation.
Cut and paste was not available as I was doing it from the text only boot up, and didn't have the network running, so I had to type it into firefox on my main system.

BarryK, sorry about the hiatus, I have been very busy on other things. The short version is:

When I am booting purely off the CD, when I have not copied the /usr data and the pup001 data to my V drive, the messages are "device not found". /dev/hdg is not present at all, in no way shape or form, when I am booting purely off the CD, and this is reported by diskpart and probepart and ls /dev/hd*. But when I copy the /usr data and pup001 data to my V drive, /dev/hdg etcetera are present, and all is well.

Because of this, I cannot simply copy/paste the error messages, because all I have is root command line when the error messages are present!

[Flash]

If you have a digital camera you can take a 'screen shot' with it, crop everything but the text and resize it to minimum resolution that is readable, then post it.

[BarryK]

Well, I have to finalise 1.0.4 tomorrow...
I can probably make an improvement based on feedback from "Guest".
Running in VMware, disktype is reporting "Track 1: Data track 0 bytes", so I can get the boot script to detect that condition and fallback to probepart, then it should detect the iso9660 filesystem.

[JonathanBrickman0000]

Sorry, no digital camera I have, however, just set up my drive partition situation differently, so that there is a FAT32 partition visible to the CD-only-boot command line (I converted my M: to FAT32). So, I can now paste the full text of dmesg, and the full text of ls -CF /dev/hd*. I hope it is very obvious that probepart cannot return anything useful using a devicename that is not present in /dev!
