Unable to mount root partition

Unable to mount root partition

Post by Corey Scob » Fri, 08 Dec 1995 04:00:00

HEEEEEEEEEEEEEEELP! For no known reason, my Linux system (Slackware 3.0) just decided to hang.
I was installing some disk packages and I'm pretty sure I ran out of disk space but I'm not sure.
If you couldn't tell by now I am a Linux newbie. The problem is that when I boot the system hangs at this
"VFS: Mounted root (ext2 filesystem) readonly."
I've tried a boot disk and get the same result.
What do I do?

By the way, if you are answering this question then please tell me how to determine how much space is
left on a hard drive partition.

Thanks in advance,


Unable to mount root partition

The root partition is mounted read only when you boot so that it can be
checked.  It should do its check(or skip it) then remount it read write.
 to check disk sapce, use du.  It has several options.  Also you can use
dp(I'm not sure off hand if that is right, it might be df or something).
 That will tell you blocks etc. free. as well as free space on each


1. Unable to mount root partition as RW on NEC Powermate V466 -Please help

Hi Linux gurus,

I'm trying to install the latest version of slackware 1.2.8 (which I
downloaded from ftp.cdrom.com ) on an NEC Powermate V466 with a 520MB
harddrive (CHS=1048/16/63) with 16MB of memory and a 486DX2-WB CPU.

I used the bare boot diskette and the color144 root diskette to
install. I noticed that during fdisk, Linux thought that my hard drive
is 524 cyls with 32 heads per cyl instead of 1024 cyls with 16 heads
per cyl as reported by the NEC BIOS setup.

The installation seemed to go OK (I did all the A disks and the N
disks) except that after creating the boot diskette and rebooting the
system (I used the IDENET kernel), after the message: large kernel:
low 1M memory tight CRC error, the system would hang. I fixed this by
disabling external caching using the NEC BIOS setup.

Then the boot process went much further but also ran into trouble with
the following messages:
Paralelling fdsk version 0.5b (14-Feb-95)
/dev/hda2 is clean, no check
Remounting root device with read-write enabled
/etc/rc.d/rc.S: /sbin/mount: No such file or directory
Attempt to remount root device as read-write failed! This is going to
cause serious problem......
Please press ENTER to continue then reboot and use one of the above
methods to get into your machine and start looking for the problem.
init[nnn]; cannot execute agetty
init[1]: no more processes left in this release (This message is
repeated forever until CNTL-ALT-DEL is pressed)

I suspected that either executables were missing or somehow the load
process could not access them.
I have tried to re-format and re-install many times but always got the
same problem. My 520 MB harddrive has 3 partitions: /dev/hda1 is an
MSDOS partition with 180 MB, /dev/hda2 is the Linux root partion with
300 MB and /dev/hda3 with around 20 MB as the swap partition.

Any help would be greatly appreciated. Please post on this newsgroup
