 |
|
Hi,
i'm having a very weird issue were my system starts with all partition mounted as read-only. Here's my fstab
(sda is an SSD, sdb a normal disk)
| Code: | /dev/sda3 / ext4 noatime,nodiratime,discard 0 1
/dev/sdb2 /home ext4 defaults,nosuid,nodev,noatime,nodiratime 0 2
/dev/sda2 /boot ext4 defaults,noatime,nodiratime,discard 0 2
/dev/sdb1 none swap sw 0 0 |
fsck says my disks are fine.
Here is the funny thing that happen if I login and try to create files in different place:
| Code: | touch /home/test2
touch: cannot touch '/home/test2': Read-only file system
touch /boot/test2
touch: cannot touch '/boot/test2': Read-only file system
touch /root//test2
touch: cannot touch '/root/test2': Read-only file system
mount -a
touch /home/test2
touch /boot/test2
touch /root/test2
touch: cannot touch '/root/test2': Read-only file system |
dmesg:
| Quote: | sda: sda1 sda2 sda3
sd 0:0:0:0 [sda] Attached SCSI disk
EXT4-fs (sda3): couldn't mount as ext3 due to feature incompatibilities
EXT4-fs (sda3): couldn't mount as ext2 due to feature incompatibilities
EXT4-fs (sda3): mounted filesystem with ordered data mode. Opts: (null) |
I think the ext3 and ext2 messages are explained by the fact that i turned off ext3/3 support in the kernel.
Any help is welcome, i'm a bit puzzled at this point ! |

I would recommend, that you first follow the gentoo-handbook.
e.g. X86/Installation/Kernel -> Selecting necessary file systems
You cannot do any mistake when selecting these kernel-options compiled in the kernel and not as a module
| Code: |
<*> Second extended fs support
<*> Ext3 journalling file system support
|
When using make menuconfig, open Help for FileSystems-> (ext4) filesystem
| Quote: | ... The ext4 filesystem will support mounting an ext3 filesystem ...
|
Generally, I would enable every kernel-options recomended by the gentoo-handbook,
later You will have time to reduce the options step by step. |
