@ccooke Hello,

You should be able to make the XOSTOR SR work again if you update sm and sm-fairlock on the other hosts.

yum update sm sm-fairlock

Then you should be able to re-plug the SR on the master and proceed with the RPU.

Hello,

Had the same problem, the command resolved the issue. It needs to be run on every host. Everything is working fine again. However, I had to complete the pool update manually.
