I want to set up a iscsi high availability with sheepdog distributed storage.
Here is my system set up. Four nodes with sheepdog distributed storage and i am sharing this storage through iscsi using two nodes as well as using a virtual ip set up using ucarp.Two nodes using same iqn. And mounted the iscsi storage as lvm partition (sdc)
Problem: when a failover happens ie iscsi switching from node one to two, the iscsi disk fails on initiator
Code:
root@prox1:~# pvdisplay
/dev/sdc: read failed after 0 of 4096 at 0: Input/output error
/dev/sdc: read failed after 0 of 4096 at 104792064: Input/output error

iscsi - iSCSI software initiator driver
The iscsi driver is a software initiator that transports SCSI commands over TCP/IP as described in RFC 3720. The initiator is administered
through iscsiadm(1M). The iscsi initiator acts as a host adapter driver that attaches the appropriate target driver (for example sd(7D) for
disks or st(7D) for tapes) for devices it discovers. See the System Administration Guide for more information.
