I have a server running GroupWise. Has a small Btrfs partition (that is full) and a large XFS partition that is mostly unused. All the GroupWise apps run in the FULL Btrfs partition. If this were Windows I could easily shrink one partition and expand the other. Apparently, can’t shrink XFS? ☹ How do I fix this space allocation problem? Tried using DD to “clone” to a larger drive (500GB to 1TB), but the image created was corrupted somehow. There should be an EASY solution, but can’t find one or think of one. [I saw KB 7018329 that talks about adding a drive, but that seems to deal with virtual drives, and I am dealing with a real hard drive. Plus, seems like data could be corrupted easily with one partition spanning 2 drives, and would cause mounting problems.] ---

Btrfs is not the right filesystem on which to install a database (i.e. GroupWise). XFS is where your domain and post office should be installed. Because it is a different filesystem that would imply it would also be a different partition than the one formatted for Btrfs. [color=blue] > Plus, seems like data could be corrupted easily with one > partition spanning 2 drives, and would cause mounting problems.][/color] First of all, a partition cannot span multiple drives. A partition is wholly contained within a single drive. If you use XFS for your GroupWise domain and post office, it (XFS) could reside on the same physical drive along with your Btrfs partition but a better solution, one that would provide better performance, would be to use a completely separate hard drive for your GroupWise data. You don’t say whether or not GroupWise is using eDirectory. Just a note: eDirectory should never be installed on a Btrfs filesystem. – Kevin Boyle - Knowledge Partner If you find this post helpful and are logged into the web interface, please show your appreciation and click on the star below this post.

I know only enough to be dangerous. But, I think domains and post office are both installed on the Btrfs. When we installed, we accepted all default locations. The Btrfs partition fills up when we fail to archive GroupWise data for a while, and when we archive if shows as less full. So on that alone I believe it is where data is located. … No eDirectory at all. ---

You would likely obtain better performance if your domain and post office were installed on XFS but that is your choice. – Kevin Boyle - Knowledge Partner If you find this post helpful and are logged into the web interface, please show your appreciation and click on the star below this post.
