Hi Team,

In one of our node, we are seeing this type of error, will it affect the production environment. Currently in PetaSAN rbd images we are not using PR-related features like exclusive-lock.

Log error on node:

Are you getting any errors on any of your iSCSI disks ? or are they working fine ? what client environment are the iSCSI clients: Linux?Win?VMWare? how many disks/images you have?

Currently we don't see any errors of our ISCSI Disk, it is working fine. Linux are our client environment.

Around 185 disks/images we are using.
