------- Comment #1 from sandeen@redhat.com  2009-02-12 11:49 -------
-30 is EROFS

I assume you've had some error that shut down the filesystem previously, can
you look?

This seems to ring a bell for me but can't remember for sure if it's fixed,
yet.

                /* start a new transaction*/
                handle = ext4_journal_start(inode, needed_blocks);
                if (IS_ERR(handle)) {
                        ret = PTR_ERR(handle);
                        printk(KERN_CRIT "%s: jbd2_start: "
                               "%ld pages, ino %lu; err %d\n", __func__,
                                wbc->nr_to_write, inode->i_ino, ret);
                        dump_stack();
                        goto out_writepages;
                }

we should maybe check for a shutdown fs here before we generate all these
messages.

Yes, it's fixed already in 2.6.29-rcX, and it's in the queue of patches that
I'm preparing for 2.6.27 and 2.6.28.
