I came across this thread while searching for the error I am facing with iscsitarget and open-iscsi. I am working on a project where i am experimenting on a hadoop cluster. I have a fuse-dfs filesystem newhdfs which is mounted at /media/ myDrive. and i have created a storage directory holding a lun image inside this newhdfs.
I get the same error that is mentioned in one of the posts on this thread. On the target I get: $/etc/init.d/iscsitarget restart $dmesg iscsi_trgt: fileio_attach(283) -5 iscsi_trgt: Registered io type fileio iscsi_trgt: Registered io type blockio iscsi_trgt: Registered io type nullio iscsi_trgt: open_path(119) Can't open /media/myDrive/newhdfs/storage/ lun3_2.img -5 where i created the lun image using the following command: $mkdir /media/myDrive/newhdfs/storage $cd /media/myDrive/newhdfs/storage $dd if=/dev/zero of=/media/myDrive/newhdfs/storage/lun3_2.img bs=1024k count=2000 now, when i run open-iscsi on the initiator, this is what i see: $/etc/init.d/open-iscsi restart $cat /var/log/messages aasthainitiator-desktop kernel: connection12:0: detected conn error(1020) aasthainitiator-desktop kernel: iscsi: registered transport (iser) $fdisk -l $cat /var/log/messages aasthainitiator-desktop kernel: session recovery timed out after 120 secs aasthainitiator-desktop kernel: sd 82:0:0:0: [sdd] Unhandled error code aasthainitiator-desktop kernel: sd 82:0:0:0: Result: hostbyte=DID_TRANSPORT_FAILFAST driverbyte=DRIVER_OK aasthainitiator-desktop kernel: sd 82:0:0:0: CDB: Read(10): 28 00 00 00 00 00 00 00 08 00 $dmesg Buffer I/O error on device sdd, logical block 0 sd 80:0:0:0: [sdd] Unhandled error code sd 80:0:0:0: [sdd] Result: hostbyte=DID_TRANSPORT_FAILFAST driverbyte=DRIVER_OK sd 80:0:0:0: [sdd] CDB: Read(10): 28 00 00 00 00 00 00 00 08 00 end_request: I/O error, dev sdd, sector 0 i tried some of the commands suggested on the thread like pvscan, lvscan, vgchange -a ly. But i get only errors on running each of them. I see, "no matching physical volumes found" on running pvscan. I see, "iscsi-target: unrecongnized service" on running service iscsi- target stop/start. On doing $netstat -pnt I see: Proto Recv-Q Send-Q Local Address Foreign Address state PID/Program name tcp 0 0 10.72.147.218:54299 10.72.147.219:3260 TIME_WAIT - Can someone help with this matter? If this is not the write place to discuss, do please guide me to an appropriate mailing list. Thanks in advance. Regards, Aastha.
