Hi all,
hope this is the right section and even the right forum for asking help on this problem.
Using LVM2 i have this partion layout:

LABEL=/                 /                       ext3    defaults        1 1
/dev/VolGroup00/VZ      /vz                     ext3    defaults        1 2
/dev/VolGroup00/VZDUMP  /dump                   ext3    defaults        1 2
/dev/VolGroup00/BACKUP  /backup                 ext3    noquota,rw      1 2
LABEL=/boot             /boot                   ext3    defaults        1 2
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
LABEL=SWAP-sda3         swap                    swap    pri=0,defaults        0 0

Now i have all my container inside /vz and i backup on /dump.
Everything works fine, but i'm a bit worried about some error/message that i got inside messages when using snapshot.
From command line there are no errors:

~]# vzdump11 --dumpdir /dump --snapshot 440
INFO: Starting new backup job - vzdump --dumpdir /dump --snapshot 440
INFO: Starting Backup of VM 440 (openvz)

INFO: file size 135MB
INFO:   Logical volume "vzsnap" successfully removed
INFO: Finished Backup of VM 440 (00:00:17)

But looking inside log message i see those line:

Jan 20 16:39:56 srv1 vzdump[12782]: Starting new backup job - vzdump --dumpdir /dump --snapshot 440 
Jan 20 16:39:56 srv1 vzdump[12782]: Starting Backup of VM 440 (openvz)

Jan 20 16:40:13 srv1 vzdump[12782]: Finished Backup of VM 440 (00:00:17)

Is there something of anomalous ?
Wy those lines EXT3-fs: dm-3: 25 orphan inodes EXT3-fs: recovery complete ?
The system has an'array of 4 disk in raid10 mode.
Tryied searching both this forum and web, and i can't find a solution.
Thanks in advance for any suggestion.
