Hi Gurus,
I am trying to grow a vxfs volume by 100G but it fails. My current file
sytem size is 1 TB (962 GB) and am trying to grow to 1.1 TB. I am
running Sol9 with VXvm 3.5
(VERSION: 3.5,REV=06.21.2002.23.14) Is there a issue with veritas vxvm
3.5 for file ssytem support > 1 TB? If i try to upgrade on another
volume which is 100GB the maxgrow command tells me i can grow to 300 GB
which means space is available for grow. Is there a bug with Vxvm 3.5?
or i am missing something like need vxrelayout? Please help.
Also i have to do a mirror volume and then preverve the data in case of
data corruption. To do this i am going create a mirror volume and then
remove the plex to preserve data. In case original data gets corrupted i
can start the volume with mirror plex. For that should i just Dissociate
plex from volume (vxplex dis mirror-plex-name) or remove a plex (vxplex
o rm dis mirror-plex-name) after mirroing volume.
Also if i need to bring the mirror plex volume what should be the procedure?
Thanks in Advance.

Volume in question is striped. I am adding 100GB (2 LUNs) to it.
