and now is the error information(i didn't use lvextend before):
[root@snap /root]# e2fsadm -L+1G /dev/raid-lvm/lv_raid
e2fsck 1.18, 11-Nov-1999 for EXT2 FS 0.5b, 95/08/09
The filesystem size (according to the superblock) is 338944 blocks
The physical size of the device is 236544 blocks
Either the superblock or the partition table is likely to be corrupt!
Abort<y>? yes

and last is the error information of useing lvextend before:
[root@snap /root]# lvextend -L+1G /dev/raid-lvm/lv_raid
lvextend -- extending logical volume "/dev/raid-lvm/lv_raid" to 1.90 GB
lvextend -- doing automatic backup of volume group "raid-lvm"
lvextend -- logical volume "/dev/raid-lvm/lv_raid" successfully extended
[root@snap /root]# e2fsadm -L+1G /dev/raid-lvm/lv_raid
e2fsadm -- new size too large for "raid-lvm"
e2fsadm -- size of "/dev/raid-lvm/lv_raid" would be invalid
TIA for your help and sorry for my poor English.
