Hello List, In libdlm code, cluster_ringid_seq variable is defined with uint32_t in dlm_controld/dlm_daemon.h, the corosync API returns uinit64_t ring_id, in the current code, we use type cast to get the low-32bit ring-id. But, in some case, the corosync returns a huge ring-id (greater than 32bit), the DLM daemon does not work normally (looks stuck). Then, I want to know if we can change cluster_ringid_seq in libdlm from uint32_t to uint64_t? If you'd like to know the details about why corosync ran into such a huge ringid, you could check the info from: https://github.com/corosync/corosync/pull/532#issuecomment-617647233 Thanks Gang _______________________________________________ linux-lvm mailing list linux-lvm@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
