I don't know what this could be, but have you tried turning on the
various GIT_TRACE env variables document in "man git"? Some of those
might hold a clue to what's going on here.

Have you tried to do other git-independent tests to see if in general
the NFS failover isn't resulting in data being written as applications
expect? E.g. doing a recursive wget of some data with known SHA1-sums,
or doing a stess test of some sort on a filesystem that uses checksums
(such as btrfs), which could be loop-mounted to a file stored on NFS.
