How to extend the volume
Dear All
My current Solaris 9.0 using the VM 4.1 version. I have the one mount point in 90 % usage, and need to extend the volume but there is no space usage. Therefore I add the new disk space to VM by using vxdiskadm c3t40d1s2
root@devuardms01 # vxdisk list
DEVICE TYPE DISK GROUP STATUS
c1t0d0s2 auto:sliced rootdg01 rootdg online
c1t1d0s2 auto:sliced rootdg02 rootdg online
c3t40d1s2 auto:cdsdisk rootdg03 rootdg online
Extend the volume dctm
root@devuardms01 # vxprint
Disk group: rootdg
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0
dg rootdg rootdg - - - - - -
dm rootdg01 c1t0d0s2 - 143318784 - - - -
dm rootdg02 c1t1d0s2 - 143318784 - - - -
dm rootdg03 c3t40d1s2 - 51193600 - - - -
sd rootdg01-06 - ENABLED 8390112 - - - -
v dctm fsgen ENABLED 20972736 - ACTIVE - -
pl dctm-01 dctm ENABLED 20972736 - ACTIVE - -
sd rootdg01-05 dctm-01 ENABLED 20972736 0 - - -
pl dctm-02 dctm ENABLED 20972736 - ACTIVE - -
sd rootdg02-05 dctm-02 ENABLED 20972736 0 - - -
I would like to know if there is way to extend the volume , is it need to downtime to extend the volume? Please provide the step to do guide me.
Thank you !
Solaris 9.0, YaY!
Ok, here is what you need to do:
You need one more disk. The reason why is because your original volume is mirrored. To extend a mirrored disk, you need to add two disks not one.
Now once you have another disk that is went through vxdisksetup, vxdg -g rootdg adddisk <diskname> and visible in vxprint, you just run:
vxassist -g rootdg maxgrow dctm
This will give the max size you can grow the volume to
Now you can refer to something like http://www.veritas.com/docs/100029279 if you have VxFS and it will be online, for other file systems you need to check whether the file system supports online resize
if memory serves me well, something like
vxresize -g rootdg dctm 106415296 alloc=rootdg03,rootdg04
should do the trick, provided it's VxFS and it is mounted
