I too am suffering from this. Whilst a proper oVirt-configuration item would be ideal, the RFE suggests that there is a manual work-around for setting sanlock's io_timeout, albeit not recommended. Could anyone share what it is? It seems clear from the sanlock code that io_timeout is the only configurable item, and that the renewal fail timeout is 8 x io_timeout. In that case, increasing the io_timeout from the default of 10 to 15 should cover me. https://pagure.io/sanlock/blob/master/f/src/timeouts.h https://pagure.io/sanlock/blob/master/f/src/timeouts.c Searching suggests two different ways. Firstly, putting, e.g. SANLOCKOPTS="-o 15", in /etc/sysconfig/sanlock, though the sanlock docs do not confirm that should work and the search hits are all very old. Secondly, as oVirt is using libvirt, setting io_timeout=15 in /etc/libvirt/qemu-sanlock.conf. Does anyone know if either of those work? Or if there's another way? Thanks, Jon
