I've been running gluster under valgrind. E.g. see
It's pretty hit or miss, sometimes the client-side glusterfs process (at
least IIRC it's the client-side glusterfs) will lock up and consume 100%
CPU. And so far I haven't been able to trigger a core dump of the
spinning process to see where it's locking up.
It would be nice to solve that so that I can do unsupervised nightly
I'll look at the review you referenced for disabling pools.
