Re: RAID5 / 6 Growth

["Majed B." <majedb@gmail.com>]

John,

I grew software RAID arrays with XFS on top without issues before. I
tried with the filesystem both mounted and unmounted. Never had a
problem. And XFS can't be grown unless it's mounted, so the size of
the block device is not the one causing the issue here, as the size of
the block device (array) is larger than what the filesystem is
occupying, which is normal.

After mounting the filesystem, the admin can increase the size of the
FS to fit the newly expanded array size.
