SLES 11 SP2: Ext4 readonly mount

Posted in Linux at 10:30 am by alessiodini

Yesterday i was doing some test on my SLES 11 for SAP.
I was trying to mount an ext4 filesystem on /mnt.

During the mount i saw the message:

mount: warning: /mnt seems to be mounted read-only

I was surprised to see that message , so i tought about some problem with lvm or iSCSi ( i maked a volume group on a disk via iSCSi ).

Looking the system messages i saw this:

Mar 19 15:59:19 suse1 kernel: [ 1147.951164] EXT4-fs (dm-2): ext4 is supported in read-only mode only

Now it was clear! I understand too why SLESS 11 had the root filesystem on ext3 🙂

    Is about the ext4 bug http://www.phoronix.com/scan.php?page=news_item&px=MTIxNDQ

    But you can mount ext4 in rw mode if you use the other module form the kernel

    ext4-writeable-kmp
