The crux of the problem is that the file system was mounted with different options than specified by user and this option can't be changed on the fly. Ext4 Data=writeback To see how to do this, follow the BBCode link below.That fstab example above, is that actually copy and pasted here? You can tune2fs -l to check whether the filesystem features include has_journal. original site Why Do That?
It would be nice to support MS_FORCE|MS_REMOUNT by mount(2) syscall and implement it as an atomic in-kernel umount+mount, then it would be possible to remount from usersapce with arbitrary mount options. Ext4 Barrier=0 Might be a solution, but also slows down the boot process. Once there, issue the following command on the filesystem: On the next boot you can find the new mount option in /proc/mounts Technical stuff: What happens there is that Ubuntu initially In case of a VPS do it from the host, otherwise from a PXE boot emergency kernel or LiveCD.
This should be fixed though. Because you are specifying the data=journal option the remount fails and the root filesystem is left read-only.I agree. Data=writeback Bad Option rebuilding updates now. Ext4 Commit You can list the options on the file system with "tune2sf -l /dev/sda1".
It always worked for me. Check This Out It will update your grub and will exit from Grub menu. Comment 16 Lukáš Czerner 2015-11-11 04:43:56 EST From my point of view the best solution would be to mount it with the right options in the first place, however if you Take it off = mounts fine. Ext4 Data=journal
Anyway what is you suggestion kernel should do about this ? Most notably xfs where the problem is much bigger, because they would currently silently drop the options (intentionally) they can't change on remount (vast majority of the mount options btw) leaving I wonder if you are getting caught by this: Code: errors=remount-ro Remount the filesystem read-only on an error. Source Registration is quick, simple and absolutely free.
Should we use that switch from systemd-remount-fs? Ext4 Disable Journaling Given the hints solve the puzzle Why is the 'You talking to me' speech from the movie 'Taxi Driver' so famous? xyepblraOctober 21st, 2009, 04:35 PMFinally I found the thread my help request it would be proper to post to.

I'm running an armbian version from June, maybe this can explain it. have a peek here The kernel the executes the 'init' process and during this the fstab is read and the filesystem is remounted read-write.
sda4 = Vbox -> mounts fine with data=writeback Maybe that's where the conflict is?!? Having a problem logging in? If the /etc/fstab was changed, then initramfs needs to be regenerated though (not sure that was the case here ?) Anyway assigning to dracut to move things forward. I followed Cody Little's guide until the last step that I did was blessing my boot partition within OSX (right before configuring XORG).Afterwards, I was supposed to boot into Arch for
Now I am being prompted with read only file system error on boot. Opts: (null) [ 17.557900] EXT4-fs (nand2): Cannot change data mode on remount [ 17.604119] EXT4-fs (nand2): Cannot change data mode on remount As the official cubieboard 2 download Several functions may not work. I'm trying to do a kickstart install for a SSD based machine, hence the need for data=writeback.
This will override the problem you created and you will then be able to go fix it. try chmod +r or +w or +a through z / miegielAugust 18th, 2009, 06:27 AMHave you tried mounting it twice, I maen monting it automatically as you boot and then manually Need help badly. Even if its not my main data volume, I like the idea of the whole OS running with the best integrity.
How do I deal with my current employer not respecting my decision to leave? afroman10496August 18th, 2009, 05:56 AMsudo chmod +x / will make it executable... Register now! do: mke2fs -t ext4 -O ^has_journal /dev/sdaX (root) 3.
