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!

Additional comments: ReiserFS 3 can be enlarged while mounted, but shrunk only when unmounted. ReiserFS 4 can not yet be resized at all. EXT2/3 can be enlarged online with a kernel patch and utils from http://ext2resize.sourceforge.net/ XFS must be mounted while enlarging but can AFAIK not be shrunk, even off-line. JFS must be mounted while enlarging but can not be shrunk, same as XFS.

My /home and /usr/local file systems are on logical volumes. The lvm script is in /etc/init.d, with a link in /etc/rcS.d, S26lvm (mountall has a greater number). dm-mod is in /etc/modules At boot time, everything stops; I have to type "modprobe dm-mod", , and everything is OK. What's wrong with my boot config.? Any hint appreciated. -- Laurent Bloch -- lbloch@noos.fr -- http://laurent-bloch.org
