File system resizing in vxvm

Hi,

We have to increase size of below filesystem. by 100GB however, I am confused which disk and diskgroup I have to check.

When I checeked vaultdg41 I found 6 GB of space free. But, when I checked vxprint o/p it shows volume v41 with subdisk emcpower38 and got confused, in b/w emcpower75 and emcpower38.

For temporary, use we can increase 5 GB, but i don't know, How should I proceed, please assist what diskgroup and disk do I have to check and what command should I use?

This is an urgent requirement, request to help as soon as possible.

 

root@lyle# df -h /vaults/v41/
Filesystem             size   used  avail capacity  Mounted on
/dev/vx/dsk/vaultdg/v41vol
                       5.0G    18M   4.7G     1%    /vaults/v41
root@lyle#

WHen checked we found the 

vxdisk list

emcpower68s2 auto:simple     vaultdg19    vaultdg      online thin
emcpower69s2 auto:simple     vaultdg24    vaultdg      online thin

    Have another look at df -h output:

    /dev/vx/dsk/vaultdg/v41vol

    This volume is in vaultdg diskgroup. 

    So, you need to look for disks in vaultdg diskgroup. Not vaultdg41.

    PS:
    I have moved this post to Storage Foundation forum.

    Do,

    vxassist -g vaultdg maxsize

    AND

    vxassist -g vaultdg maxgrow v41vol

    will provide same information of  maximum size to grow?

     

    Thanks.

    You are in the perfect situation where you can issue both commands and see the difference in output for yourself. The maxgrow command will take the current volume layout into account. Remember your previous attempt to grow a striped volume?

    As your volume is not striped or mirroed, then both should give the same, but as Marianne says, if the volume you are growing is mirrored or striped, then maxgrow and maxsize may give different results.

    Mike Can you suggest, if I have to increase the size of the volume through a particular disk, then which command should I have to use?

    For instance, through vxdg -g dgname free, I got the info that emcpower75 disk has some space in vaultdg diskgroup may be 6 GB to extend, then which command do I have to use?

    I believe if i go with with vxassist -g vaultdg maxsize command and then resize the volume, it would take space from any of the disk which there also chance of data corruption, right?

    Please suggest?
