The complete fsck was able to repair it, but it shrunk it back to the old size again.

I've just attempted a gfs2_grow again on the filesystem (and confirmed all hosts see the disk, which is a CLVM LV, as the same larger size), and whilst it's grown to the correct size I shortly receive ENOSPC errors when it tries to use the extra disk space.

To work around the problem for now, I've provisioned a new LV of the larger size, created a new GFS2 filesystem on it and rsync'd the data across.

I've kept the old LV + filesystem available to do any further debugging, if necessary.

Regards,
Tom
