I have a little problem with LIO iscsi target and SPC-3 persistent
reservation.
The summary of my setup is:
host:
centos 6.5 x86_64 with custom kernel 3.16.3 + scst patches
targetcli (-fb) 2.1.fb37
this host is configured to export a lun0 to the guest via iscsi
guest:
centos 7 x64_64 with stock kernel 3.10.0-123.6.3.el7.x86_64
iscsi-initiator-utils-6.2.0.873-21.el7.x86_64
sg3_utils-1.37-5.el7.x86_64
[snip]
the guest virtualization is done with qemu-2.0.0+kvm, NIC is virt-io and
the guest
connect to the host via a tap device.
The guest can connect to the iSCSI target and i see the device as /dev/sda.
I partitioned, formatted and mounted it successfully.
My problem that every PR Out command return a sense key not ready
even if the command run successfully, see this sequence:
I think I already experienced these errors. Could you check the
output of `dmesg` and look for errors like:
filp_open(/var/target/pr/aptpl_1a4f52f5-1036-498a-a14f-8818d28de1bb) for APTPL metadata failed
SPC-3 PR REGISTER: Received res_key: 0x0000000000000000 does not match existing SA REGISTER res_key: 0x000000002e5f2049
filp_open(/var/target/pr/aptpl_1a4f52f5-1036-498a-a14f-8818d28de1bb) for APTPL metadata failed
You can fix this issue by creating the /var/target/pr directory.
You should also create the /var/target/alua directory whih is
expected by LIO too.
Best regards,
Oh yeah! that was the problem! my bad I didn't checked dmesg on host :(
I didn't thought about aptpl because I ask for reservation without aptpl
bit on
(-Z flag in sg_persist).
I created the 2 directories and now PR works like a charm :)
thank you very much!
Luigi
