    growfs not growing the FS

    918007
      Hi.. There is a task to add space on one of the FS with 10GB.

      Storage team has allocated the disk name "emcpower7a" having 10GB size. i have formatted, labelled the disk before adding it into the metadevice d80. but after doing the # metattach d80 emcpower7a and doing growfs on the FS, the FS size remained the same. Is there any way to remove the device emcpower7a from d80 that i have attached earlier, reformat it and reattach and do a growfs on the FS.

      root@modena> metastat -p d80
      d80 4 1 emcpower0a \
      1 emcpower4a \
      1 emcpower7a \
      1 emcpower10a

      root@modena> df -kh|grep -i d80
      /dev/md/dsk/d80 97G 64G 32G 67% /apps/ora/oradata


      root@modena> metastat d80
      d80: Concat/Stripe
      Size: 204565760 blocks (97 GB)
      Stripe 0:

      Thanks for your help in advance.

          How about showing us the output of the command:

          <pre>/usr/sbin/prtvtoc /dev/rdsk/emcpower7a</pre>

              Ok that looks like I would expect. May we see the prtvtoc output from the other three disks please?

              Go ahead and include a "metastat -t d80" while you are at it.

                  I am disturbed the timestamps didn't show when you specified the "-t". Also your block counts are not adding up right. If you subtract the blocks from the disk you added you are left with a lower number than the size of d80.

                    Yes.. That is my concern too.. The timestamp for all the volumes with devices emcpower* is not showing up but all looks good for those with the internal device.

                    Is it possible that this might have happened when i allocated the disk, the disk was not fomatted/labelled properly?
                    If we try to remove the device emcpower7a from d80, would it corrupt the data already available in d80?

                    as far as i'm aware, when i ran growfs after adding emcpower7a to d80, there was no change in the size of the FS.. but after i added emcpower10a (10GB in size), (following the normal procedure), the FS size increased with with 10GB.
