It means a process running has a file open on the MyDocs partition.

Give it a reboot, then try the umount etc as soon as the phone has booted.

If it still complains about open files, then it's probably a widget that's got an open file lock...

One other thing to try, to avoid a reboot, would be to just 'cd' to another directory outside of /home/user/MyDocs, in case you're the one sitting in /home/user/MyDocs in the Terminal, holding up the umount.

I added 'cd /' after 'sudo gainroot' in the orginal commands

Code:
sudo gainroot
cd /
umount /dev/mmcblk0p1
fsck -af /dev/mmcblk0p1
mount /dev/mmcblk0p1 /home/user/MyDocs

That's a very good point...

You do not have to avoid a reboot, but in that case, if you are not on that directory and you would like which program is blocking the partition and avoiding it to be umount you can use
lsof /dev/mmcblk0p1

and you'll see which applications are using that device, of course that command can be usefull in other situations

And actually, you'd probably want to something like...

Code:
cd
sudo gainroot
...
where the first 'cd' would put you in /home/user, with the unprivileged 'user' account.

because if you were sitting in /home/user/MyDocs before you did the 'sudo gainroot', you'd still have the same problem

Thank you Guys!! I finally got fsck to work. I cd'd to / both before after becoming root,

lsof sounds like an interesting command, but It didn't give me any result, even when dropbox was syncing in the background...

I hope all my read-only file systems are gone for good. Once again, thanks to all!

fsck did not help me here! will formatting the MyDocs partition lead me to a state where I have to reinstall the EMMC image?

basically I have one rogue directory that I am not able to delete including its contents. Plus my MyDocs partition keeps turning into readonly on its own!

install backup menu , let it load ,connect your n900 to your pc, press "w" , do whatever repairs or format the first partition on the emmc .
if it gets mounted automatically on your box , unmount it by issuing
umount /dev/sdb1 , replace sdb1 with the correct name in your situation .
don't forget to format it as fat32 . I recommend that you use gparted for any modifications to your partition .
