I know there is a ML ocfs2-user, but it has such low traffic (no E-Mail in the second half of 2020 !) that it doesn't help much. I have a two-node HA-cluster with pacemaker. My ressources are virtual domains. The virtual disks of the domains are raw files on an OCFS2 volume on a SAN. Each evening the domains are shutdown to make a consistent reflink of each raw file which i copy afterwards in the background to a CIFS share.

I "think" the call of the function ocfs2_reflink_ioctl returns a "-17", which indicates clearly that someting is wrong. But i have no idea what. My systems are SLES 12 SP5 with kernel 4.12.14-122.46-default and ocfs2-tools-1.8.5-3.3.1.x86_64. The point is that i have trouble starting some domains after creating the reflinks, some fail occasionally and boot e.g. into emergency mode and i try to narrow down the problem. I'd appreciate very much your help. Thanks.
