Slackware root floppy mounted read-only.

Slackware root floppy mounted read-only.

Post by Danny » Thu, 06 Jan 1994 14:42:21



I am unable to install Slackware 1.1.1 using setup due to an error
(twice, in fact) with file /etc/mtab.  I am unable to continue
installation because the mounted filesystem is read-only, which I assume
means the root filesystem currently mounted through fd0.

Any ideas?  Anyone like to talk me through this one?

1. Slackware 3.0 bootkernel floppy can't mount root

 I am somewhat of a bunny, so please bear with me here :)

Installed Slackware 3.0 on 2.1GB SCSI Conner HDD with Adaptec 2940W
controller.  All hardware including SCSI CD-ROM (Matshita CD-504)
detected with install boot floppy. The kernel I installed (Selcted
in setup ) was 1.2.13.

Below is the detected disk geometry and partition table with Linux
fdisk:

Disk /dev/sda: 255 heads, 63 sectors, 261 cylinders
  Units = cylenders of 16065*512 bytes
 (= 8,225,280 bytes per cylinder = 2,146,798,080 bytes - looks ok)

  Device  Boot Begin Start   End   Blocks    Id  System
/dev/sda1   *     1     1    134  1076323+    6   Dos 16-bit >=32
/dev/sda2       135   135    200   530145    83   Linux Native
/dev/sda3       201   201    257   457852+   83   Linux native
/dev/sda4       258   261    134    32130    82   Linux Swap
-------------------------------------------------------------
On /dev/sda1 is Windows 95 which will change eventually
(i.e. I want Linuix as primary boot partition with Lilo
on MBR _eventually_. But first want to crawl before walking)

I have linux root installed on /dev/sda2 and /usr to /dev/sda3

Now here is what happens when trying to boot from bootkernel
floppy (Simple /vmlinuz) created with setup:

"Kernel panic: VFS: Unable to mount root fs on 08:02"

The same result when configuring Lilo and installing Lilo
on a boot floppy (Dos- Win95 boots fine with LILO even when
I set the bootable flag on /dev/sda2 with linux fdisk - Every-
thing looks correct in Lilo config file)

I am however able to mount root with the install boot floppy
when typing "mount root=/dev/sda2" at the "boot:" prompt.
I do however get the obligatory warning about the bootkernel
being read-write (only supposed to be read only) prior to fs
checking. Just press C/R anyway :)

When the HDD boots (or mounts or whatever it is doing -
much disk activity here) at the login prompt I get "Welcome
to Linux 1.3.18"

machinename login:

I installed kernel 1.2.13!!! I am sure of it. Could setup
be installing 1.3.18 kernel on boot/root setup disks by
default? I would think not, but who knows?

Should I try yet another install? All previous installs were
from the slackware CD - maybe should try hardisk install? It would
only be the tenth or so install attempt! lost count:(

Should I try recompiling the 1.2.13 kernel?

Please any methodical advice is welcome. I have been at it for almost
1 month now. (Pity accepted also :)

Regards,
Steve
