FC4 Read Only

Electrified · 09-03-2005, 06:52 AM

I have installed Fedora Core PPC on my PowerMac 466 and after some trouble (Disc was labeled as msdos) it booted. But /etc/fstab was really fucked up with allot of stange symbols so I made a new one. Now it only mount / as read only

The line in fstab looks like this

Code:

/dev/hda3	/            	ext3     	defaults       	1 	1

Is this wrong?

EDIT: Remounting root as read/write is failing

EDIT2: I remember having this problem some other time when I just had recompiled my kernel. But this was on a PC. Do you think there might be anything wrong with the kernel? (It's 2.6.11-1.1369_FC4)

Yes.

Check what grub.conf says is the root partition, and see that you have a root=LABEL=/ in the kernel line.

Here is my fstab (for fc4 OK, but it should be OK)

Code:

# This file is edited by fstab-sync - see 'man fstab-sync' for details
LABEL=/                 /                       ext3    defaults                        1 1
LABEL=/boot             /boot                   ext3    defaults                        1 2
/dev/devpts             /dev/pts                devpts  gid=5,mode=620                  0 0
/dev/shm                /dev/shm                tmpfs   defaults                        0 0
/dev/proc               /proc                   proc    defaults                        0 0
/dev/sys                /sys                    sysfs   defaults                        0 0
LABEL=swap               swap                   swap    defaults                        0 0
/dev/fd0                /media/floppy           auto    pamconsole,exec,noauto,managed 0 0
/dev/hdc                /media/cdrecorder       auto    pamconsole,exec,noauto,managed 0 0

This should provide a comparison. The labels are spelled out in grub.conf. I hope you kept a backup of the original fstab?

Since I'm on a Mac I can't use GRUB. I use yaboot instead. I've tried LABEL=/ in fstab and root=LABEL=/ in yaboot but then I get "Unable to resolv Label=/" And I've tried e2label /dev/hda3 / but it still doesn't work.
I'm going to compile a new kernel and se if it works.

EDIT: This is really strange. When I plugged in the mac harddrive into my PC with FC3 and booted it couldn't remount root

But when I removed it again it worked just fine. How the hell can the mac disc, Which isn't even mounting, Stop my PC root drive from remounting?!?

EDIT2: I think the solution to the problem would be to get LABEL=/ to work. When I boot I get

Code:

fsck.ext3: Unable to resolve 'LABEL=/'

Why do I get this error message?

Ok now it's booting. I had to remove the read-only option in yaboot and change LABEL=/ to /dev/hda3. But now I'm afraid fsck will fsck up my drive. Does anyone know why I can't use LABEL= in /etc/fstab???

so your root partition was hda2 not hda3 as you said at first.
you will probably find things become clearer if you fdisk -l

how to use label= will probably be explained in the documentation that comes with your bootloader.

Sorry, It is hda3. hda1 is a partitiontable or something on mac, hda2 is where the apple bootstrap is och /hda3 is my root.

good good - it seems popular for manufacturers to include a very small (a few kay) recovery partition at the beginning of the HDD. This can sometimes cause confusion.
