You can grow xfs partitions with xfs_growfs, which has a man page. Make
sure you have the 'xfsprogs' RPM (available via apt) if you're using an
RPM-based distro. As my problem seems to be accumulation of data, I've
never needed to shrink a partition. ;)
Incidentally, a minor warning about xfs over lvm. While I've never had
corruption with xfs over lvm alone, I tried running an AES encrypted
loopback partition (work security requirement) over xfs over lvm (over
SATA, but I don't think that mattered), and *always* got corruption; I
couldn't even build an ext2 filesystem on the loopback and then remount
it. I finally grabbed an old drive and looped a disk partition, that
worked fine. Never had problems with cryptoloop over ext3 either.
I don't know whether this is a problem with xfs, lvm, or the cryptoloop
modules (which I had to build from source, despite the export regs being
dropped. grr.) So, xfs over lvm *may* be buggy, but I've decided it's
stable enough for TV recordings. Like I said I've never had corruption
(that I know of) except with aes/cryptoloop.
