Description of problem:
I am unable to use ext2 labels to mount lvm based partitions.  It fails with a LABEL=<label> duplicate - not mounted.

It appears to be based on the partition being references in multiple searches in the /proc filesystem for mount points.

Version-Release number of selected component (if applicable):
util-linux-2.12a-16.EL4.6 lvm2-2.00.31-1.0.RHEL4

How reproducible:

Steps to Reproduce:
1. create lvm partition : lvcreate -n test -L 128M lvm0
2. format partition : mke2fs /dev/lvm0/test
3. use e2label to label partition : e2label /dev/lvm0/test testlabel
4. mount LABEL=testlabel /mnt


Actual Results:  # mount LABEL=testlabel /mnt
mount: LABEL=testlabel duplicate - not mounted

Expected Results:  Successful mouting

Additional info:

# strace -eopen mount LABEL=testlabel /mnt

mount: LABEL=testlabel duplicate - not mounted

Comment 1 zweers 2005-06-02 23:49:15 UTC
Obvious fix is to mount by path and not by label.
