P acemaker + corosync cluster with 2  virtual machines (ubuntu 22.04, 16 Gb RAM, 8 CPU each) are assembled into a cluster, an HBA is forwarded to each of them to connect to a disk shelf according to the instructions  https://netbergtw.com/top-support/articles/zfs-cib /. A ZFS pool was assembled from 4 disks in draid1, resources were configured - virtual IP, iSCSITarget, iSCSILun. LUN connected in VMware. During an abnormal shutdown of the node, resources move, but at the moment this happens, VMware loses contact with the LUN, which should not happen. The journalctl log at the time of the move is here:  https://pastebin.com/eLj8DdtY . I also tried to build a common storage on drbd with cloned VIP and Target resources, but this also does not work, besides, every time I move, there are always some problems with the start of resources. Any ideas what can be done about this? Loss of communication with the LUN even for a couple of seconds is already critical.
