lvrename to a mounted device
Hi,
I wanted to rename a filesystem but I forgot to unmount it before running lvrename and now it is still visible when doing df -k

old name
device:
/dev/mapper/vg01-MGRSTR3
mounted as /MGRSTR3

new name:
/dev/mapper/vg01-mgrusr3
mounted as /mgrusr3

when trying to unmount the old one i'm getting 'device busy' but 'fuser -cu' doesnt show any process running

[root@server MGRSTR3]# umount /dev/mapper/vg01-MGRSTR3
umount: /MGRSTR3: device is busy
umount: /MGRSTR3: device is busy


how can I fix this?

df -k output:

Code:
/dev/mapper/vg01-MGRSTR3
                      75957344  44354216  27746528  62% /MGRSTR3

/dev/mapper/vg01-mgrusr3
                      75957344  44354216  27746528  62% /mgrusr3
