Default mount options ignored on ext3

Default mount options ignored on ext3

[Krzysztof Olędzki]

Hello,

It seems that "Default mount options" from ext3 fs is ignored by
the linux kernel. I have just set "Default mount options" to
"journal_data" on my root fs but kernel still mounts it with
journal_data_ordered:

(part of dmesg)
EXT3-fs: mounted filesystem with ordered data mode.
                                 ~~~~~~~~~~~~~~~~~
VFS: Mounted root (ext3 filesystem) readonly.

$ tune2fs -l /dev/md0
tune2fs 1.32 (09-Nov-2002)

Filesystem features:      has_journal dir_index filetype needs_recovery sparse_super

                          ~~~~~~~~~~~~
Filesystem state:         clean

$ uname -r
2.4.21-pre4

And ofcourse, it is not possible to remount ext3 fs and change
journalling mode.

Best regards,

I am pretty sure you didn't try "append=rootflags=data=journal" did you? :)

Yes. This is true. But if I have to set rootflags= I can't find any reason
for allowing to change "Default mount options". Kernel ignores it, mount
ignores it... Hm....

Well, those option is ignored for your ROOT device. Anything else != rootfs 
will work with mount options / fstab.
