Hi Jitendra, thanks for the data you provided. I have some questions in order I can better simulate your environment:
(a) You said "vendor's iSCSI target" <- can you elaborate more about this, like which vendor/solution are we talking about? (b) You mention, in the last comment: "note that Ubuntu host is running in a virtualized environment" <- the scsi removal is being executed in a virtualized env? If so, what is the hypervisor/VMM used? KVM/qemu, VMWare, etc... Any clarification regarding the environment virtualization is very useful. (c) "Currently system is in repro state" <- this is interesting, is it still in reproduce state? If so, can you run the following commands as root user? echo 1 > /proc/sys/kernel/sysrq dmesg -c > /root/dmesg.out echo w > /proc/sysrq dmesg > /root/dmesg.w echo l > /proc/sysrq dmesg > /root/dmesg.l This would help to understand if there's a potential deadlock ongoing.
