Ignore the that, sorry.
For simplicity's sake, I changed the dirs in the above example. In reality the situation was more like this:
/mnt1 and /mnt2 are separate fs's.
/mnt2/test1 is symlink to /mnt1/directory
then
mount --bind -o ro /mnt2/test1 /mnt2/test2 mount --bind -o remount,ro /mnt2/test2
but it seems I'm longer able to duplicate that either. (The reason I was able to duplicate it in the first place was propably that the first hanging mount process kept /mnt2/test1 somehow busy and I retried with mount --bind -o ro /mnt2/test1 /mnt2/test3.)
I'll drop you a note if I figure out how to reproduce it.
BTW: This should be reproducible (for what it's worth):
$ mount (...) /dev/hde1 on /mnt/ext2-2 type reiserfs (rw,noatime,nodiratime) $ touch /mnt/ext2-2/a $ rm /mnt/ext2-2/a $ mount --bind -o ro /mnt/ext2-2 /tmp/test $ mount --bind -o remount,ro /tmp/test $ mount (...) /dev/hde1 on /mnt/ext2-2 type reiserfs (rw,noatime,nodiratime) /mnt/ext2-2 on /tmp/test type none (ro,bind) $ touch /mnt/ext2-2/a touch: /mnt/ext2-2/a: Read-only file system $ umount /tmp/test $ mount (...) /dev/hde1 on /mnt/ext2-2 type reiserfs (rw,noatime,nodiratime) $ touch /mnt/ext2-2/a touch: /mnt/ext2-2/a: Read-only file system $ mount -o remount,rw /mnt/ext2-2 $ touch /mnt/ext2-2/a
