To be honest, I couldn't find good directions on how exactly to
resize an array to be smaller so I put some bits and pieces together
to do it. Guess I didn't understand everything beforehand because I
didn't read anything about resizing the file system. I thought
setting the "array-size" would take care of moving data before
rebuilding onto the 6 disks.
Since I haven't resized the XFS filesystem, any recommendations on
what to do next? Think it's possible to recover any of the data?
For what it's worth, I haven't done anything to the 2 disks that I
was going to remove.
XFS isn't shrinkable. See if
xfs_check /dev/mdX
tells you anything. If you have a backup, a restore would be the
fastest option. If you don't, and you have no other possible way of
recovering the data from another source, try
xfs_repair /dev/mdX
I usually run it with the verbose flag on so I can see what its doing.
I am not sure it will work, or result in recoverable data.
If you need to shrink xfs file systems, in general, it is best to use
xfsdump/xfsrestore or tar.
