SVM and "shrinking" a metadevice
I support a group that found out Solaris 9 4/03 doesn't support multi-terabyte file systems (e.g. over 1 TB) so growfs won't go past 1TB. SVM does as metattach will gladly add storage to an existing metadevice.
So now they have this 2TB RAID0 metadevice but they can't grow the file system on top of it.
Is there anyway to:
- Since maintenance upgrades are no longer supported, is there any patch revenue to get the multi-terabyte file system functionality into the OS ? (I know I've kinda asked a question that I've already answered with my qualification.)
- Is there anyway to "shrink" the metadevice without having to destroy it first ?

This should work considering:
- Only the metadevice was expanded - not the file system
- This same concept is used to rebuild a metadevice of shadowimage storage coming off a HDS for backup purposes.
umount /GD <<< this is what d32 is mounted as
