Hi, = all,

 

    After I = used LVM2 to create PV, VG, LV on the attached storage

disks, I want to format = logical volume as a file system and

possibly extend the file = system of LV online. But = when I prefer to

“ext3” file system, I find the tool “resize2fs” only can resize

ext3 file system = offline.

 

    OS: = Linux Fedora Core2(kernel 2.6.7-1.494.2.2smp)

    LVM = version: 2.00.15(2004-04-19)

    Library = version: 1.00.14-ioctl(2004-04-06)

    Driver = version: 4.1.0

 

    = Operations:

    = pvcreate /dev/sda

    = pvcreate /dev/sdb

 

    = vgcreate vg1 /dev/sda /dev/sdb

    = lvcreate –L 100G –n lv1 vg1

 

    mke2fs /dev/vg1/lv1

    mount /dev/vg1/lv1 /mnt

    = lvextend –L +50G /dev/vg1/lv1

 

    Then I = used “resize2fs” tool to = extend file system, but failed.

I know it = must be done when “umount” the = lv1.

    If = another tool can finish that running under Linux?

 

    Or if = any other file system can be mounted and resized online under Linux? =

XFS? I = don’t know.

 

Anyone can = help me? Thanks!
