Posted: Wed Oct 10, 2012 2:13 pm Post subject: Kernel Boot error |
|
|
I have configured my kernel for a new server.
when i boot up i get...
Code: |
EXT3-fs (sda3): error: couldn't mount because of unsupported optional features (240)
EXT2-fs (sda3): error: couldn't mount because of unsupported optional features (240)
EXT4-fs (sda3): error: mounted filesystem with ordered data mode. Opts: (null)
VFS: Mounted root (ext4 filesystem) readonly on device 8:3.
|
Then some stuff about kernel memory..
What could be the problem ?
I have had the problem with my rootfs mounting as RO but not this.
my fstab is:
Code: |
/dev/sda1 /boot ext2 defaults,noatime 0 2
/dev/sda2 none swap sw 0 0
/dev/sda3 / ext4 noatime 0 1
/dev/cdrom /mnt/cdrom auto noauto,user 0 0

not really a problem. just says ext2, ext3 can't mount an ext4 file system
leave alone
or
add rootfstype=ext4 to grub's kernel line
and/or
menuconfig: Quote: | < > Second extended fs support
< > Ext3 journalling file system support
<*> The Extended 4 (ext4) filesystem
[*] Use ext4 for ext2/ext3 file systems (NEW)
[*] Ext4 extended attributes (NEW)
[ ] Ext4 POSIX Access Control Lists (NEW)
[ ] Ext4 Security Labels (NEW)
[ ] EXT4 debugging support (NEW) |

Sorry I should have been more clear.
This happens and then the system fails to boot.
Any suggestions on why this would happen ? _________________ Slugggerzzz ... |

Hello Sluggerzzz
Get a live DVD and chroot into your environment.
Rebuild the kernel with the options DONAHUE points out. _________________ Whatever you do, do it properly! |
