A new create LVM volume and a ext3 filesystem seeems to be ok. And
online resizing is possible without problems.
$ sudo lvcreate -n tmp -L 1G system
$ sudo mkfs.ext3 /dev/mapper/system-tmp
$ sudo file -s /dev/mapper/system-tmp
/dev/mapper/system-tmp: symbolic link to `../dm-7'
$ sudo file -s /dev/dm-7
/dev/dm-7: Linux rev 1.0 ext3 filesystem data, UUID=f676c63e-81e6-4fc8-a78b-8247082af1f6 (large files)
No message from the file command about a need to journal recovery!

resize2fs does not expand filesystem; no error messages are displayed
Status in “e2fsprogs” package in Ubuntu:
Assuming /dev/mapper/system-backup has 50GB of space ...
1. Expand an LVM volume with lvextend:
lvextend -L +50G /dev/mapper/system-backup
2. Resize the filesystem:
All seems OK, no warning or error message will be displayed. No errors in syslog, too.
BUT the filesystem is only 50G big, the additional 50G will not be available.
df -h will tell you, that there is 50GB of free space, but if you try
to use this space, you will see the error: "filesystem full".
This bug exists at least since Ubuntu 10.10! Ubuntu 12.04.1 is also
