    I have tried to do fullbackup with snapshot, the error appears.

    Do you really want to remove active logical volume "ZimbraBackup"? [y/n]:   Logical volume "ZimbraBackup" successfully removed
    Backup ended at:
    Sat Jul 29 04:41:52 CST 2006
    my fullbackup script
    Code:
    #fullbackup.sh
    #!/bin/bash
    
    time=`date +%Y-%m-%d_%H-%M-%S`
    
    #########################################
    # Modify the following variables according to your installation
    #########################################
    
    # backup_dir - directory to backup to
    backup_dir=/opt/fullbackup
    
    # zimbra_vol - the Logical Volume that contains /opt/zimbra
    zimbra_vol=LogVol00
    
    # vol_group - the Volume Group that contains $zimbra_vol
    vol_group=VolGroup00
    
    #########################################
    # Do not change anything beyond this point
    #########################################
    
    # Output date
    echo Backup started at:
    date
    
    # Enable Snapshot
    /sbin/modprobe dm_snapshot
    
    # Stop the Zimbra services
    /sbin/service zimbra stop
    
    # Create a logical volume called ZimbraBackup
    /usr/sbin/lvcreate -L1000M -s -n ZimbraBackup /dev/$vol_group/$zimbra_vol
    
    # Create a mountpoint to mount the logical volume to
    mkdir -p /mnt/ZimbraBackup
    
    # Mount the logical volume to the mountpoint
    mount /dev/$vol_group/ZimbraBackup /mnt/ZimbraBackup/
    
    # Start the Zimbra services
    /sbin/service zimbra start
    
    # For testing only
    #echo Press Enter to continue . . .
    #read input
    
    # Create the current backup
    mkdir -p $backup_dir
    tar zcvf $backup_dir/zimbra.backup.tar.gz /mnt/ZimbraBackup/zimbra/ > /dev/null
    
    # Unmount /mnt/ZimbraBackup and remove the logical volume
    umount /mnt/ZimbraBackup/
    /usr/sbin/lvdisplay
    echo y | /usr/sbin/lvremove /dev/$vol_group/ZimbraBackup
    
    # Output date
    echo Backup ended at:
    date
    So many directory can not stat. What's the problem?

    Default

    I only used tar command to do the fullbackup, and no error appears.

    The conculsion is that it can not use snapshot to do backup.
