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
