iSCSI help required

[Rais Ahmed]

using san storage with iscsi multipath, connected 3 storage drives after removing one volume, i am continuously receiving following error.. restarted multipath services but still same error. i think it should resolve after restarting iscsi service or rebooting host server, but i need a solution without restarting iscsi or server. its a production server. pls help

this looks to me like a iscsi connectivity problem
the LUNs exposed from your SAN are not available, hence the kernel cannot perform IO on the associated bloc device

verify if your iscsi session is still active with:

iscsiadm -m session -P 2

you should be logged in and active

LUN and volume is removed from proxmox server and removed from SAN.
