Confusion in vxfs & ufs
Hi All,

I have rootdg encapsulated within Veritas Volume Manager.
Code:
/# vxprint -vg rootdg
TY NAME         ASSOC        KSTATE   LENGTH   PLOFFS   STATE    TUTIL0  PUTIL0
v  rootvol      root         ENABLED  24585216 -        ACTIVE   -       -
v  swapvol      swap         ENABLED  20484288 -        ACTIVE   -       -
v  temp_back    fsgen        ENABLED  73400320 -        ACTIVE   -       -
v  var          fsgen        ENABLED  24585216 -        ACTIVE   -       -
/# fstyp -v /dev/vx/rdsk/bootdg/var | head -1
ufs
/# fstyp -v /dev/vx/rdsk/bootdg/rootvol | head -1
ufs

I just created this new volume temp_back inside rootdg. Since rootdg is encapsulated within Veritas Volume Manager, I am not sure if I should run mkfs or newfs to create new file-system. I am afraid, I should not screw my root thing.
Please help.

vxvm and vxfs are different things... one is a volumemanger and the other a filesystem.

Is the name of the volume group "rootvg" or "bootvg"? You seem to be talking about 2 VGs here.

Go ahead and make the FS in your volume, that won't destroy your other volumes in your DG.

Here's the syntaxe I use:
Code:
mkfs -F FSTYPE -o OPTIONS /dev/vx/rdsk/DGNAME/volumeName

I put largefiles as an option to be able to have files over 2 Gbytes. Might not be needed in your case but I need it most of the times.

You'll then have to mount it and if you want it to be mounted on boot, don't forget to edit your /etc/vfstab.

Thanks plmachiavel. I am able to do it with your syntax. I am good now.
rootdg and rootdg seems same. vxprint gives me same output for both
