Re: veritas volume manager


Hi,

You can use either "vxresize" or "vxassist" command to extend the veritas file system.



vxresize:

#vxresize -F vxfs disk
disk ---> spare disk
size ---> in gb, mb or sectors . default is sectors
eg:

#vxresize -F vxfs /test 18g disk1

vxassist:

# vxassist growto length
(To extend the volume to a specific length)

# vxassist growby length
( To extend the volume by a specific length

For example

>/opt/VRTS/bin/vxresize -F vxfs -g rootdg usrvol 2140000

Use man pages also.

Re: veritas volume manager

Hi Avizen,

Below is an example of the command to extend a vxvm volume.

# vxresize -F vxfs -g your_dg your_vol +100g

will add 100GB to your_vol

Re: veritas volume manager

I am not quite familiar with VxVM but here is a cheat-sheet page, to find all VxVM related commands and info:

http://www.blacksheepnetworks.com/security/resources/veritas/veritas_lvm_cs.htm

finding the info you need is not as trivial as vgdisplay command on LVM unfortunately.

Good luck

Re: veritas volume manager

Hi,

Not sure what you mean exactly by VxSF_FULL. If you are referring to Veritas Storage Foundation then that is not a free product as it offers alot more functionality over the base VxVM product.
If you are looking for Veritas's equivilent to OnlineJFS, that is already available as standard functionality in the base VxVM.

Re: veritas volume manager



normally in hpux if i want to extend any logical volume i should perform below task.

1) umount /tmp (/dev/vg01/lvol7)
2)lvextend -L 5000 /dev/vg01/lvol7 this will extend current lvol7 to around 5g
3) extendfs -F vxfs /dev/vg01/rlvol7
4) mount /dev/vg01/lvol7 /tmp

what are the steps i should perform in veritas volume manager

i am having /tmp which is in

/dev/vx/dsk/rootdg/testvol

and rootdg having space to extend,


also in my privious question i asked about Online JFS, is there any similiar utility available for veritas volume manager so we can extend current file system without umount it,

if yes is it freeware, where to download, thansk,

No, for an application of this sensitive nature, you expect to pay a lot for it, so you know your data isn't corrupted and to have support.
