Not as regards the one in current 5.2.

I had this issues:

- locking with samba running on a single node that caused continuous
freezes of the shares, even when exported read-only after the latest
kernel+cman update (this could have been cased by the fact that not
all nodes have been rebooted after the update). After a reboot of all
nodes and a switch to the old stable gfs this hasn't happened any
longer.

- the last modification time of a file is not always updated on all
nodes (doing an ls of the same file on different nodes may show
different modification time after it has been edited on a node).

- sometimes the space used by deleted files is not freed. Launching
gfs2_fsck -y on unmounted filesystem detect lots of "Ondisk status is
1 (Data) but FSCK thinks it should be 0 (Free)" messages, but, despite
that, the space is still not freed.

BTW I've still a corrupted gfs2 empty filesystem that shows incorrect
free space if someone feels like to debug it.

Regards,
Diego.
