Hi all exprets in VXvM

can you please tell me which type of layout is there in this vxprint display.
roo # vxprint -g esintprd-stell-dg -htv

This is the file system :/opt/stellent/server Current size of this file system is 39GB, and i have to increase the file system size by 50G to this file system.

what would be the command i use to resize the file system. I am sending attaching one doc, that i have prepared, can you cross check it.

Hi Indrajit,

This volume is a mirror-concat volume (2 data plexes).
To extend I would use /etc/vx/bin/vxresize -F vxfs? -g esintprd-stell-dg +50g alloc=Cstellvol??,Pstellvol??

This will extend both the volume and filesystem by 50Gb.

From the output above though it looks like the volume is already 80Gb in size not 39Gb as you stated?

oops forgot to add volume name after diskgroup:

/etc/vx/bin/vxresize -F vxfs -g esintprd-stell-dg stellvol +50g alloc=Cstellvol-??,Pstellvol-??

The question marks should be replaced with a disk that has the required space to fulfill the request.

cheers

Richard

hi ;

as richard said , this voluem has ~80gb. perhaps it is extended but filesistem is not extended by extendfs.

I would extend fs first by extendfs .

umount it.
extendfs /dev/vx/rdsk/esintprd-stell-dgstellvol
mount it

look at size

You can use the vxresize command as shown by Richard to avoid the extra step of filesystem resizing by fsadm command after volume growth.

You also can use the "vxassist growby" stanza,
where you can specifically exclude disks by prepending a shell quoted exclamation mark.

But before you need to find out if the free pool for this particular disk group has sufficient free blocks for allocation.
You can find out by

# vxdg -g sintprd-stell-dg free

Hi,

The vxvm volume stellvol is correctly extended to 81Gigabyte.

To extend the filesystem, online, use the following command.

#fsadm -b 81788928
