Problem working with WBSAirback (Bacula) and TS3500

Postby rodrigo_fsantos » Sat Nov 17, 2018 2:22 am

I'm trying to work with WBSAirback (Bacula Enterprise) and TS3500 LTO5 drive through Starwind Tape redirector.

I'm able to mount, label and write some backup jobs, but sometimes I get an I/O error (results attached)

These are the errors logs on Starwind console..
11/17 0:50:34.545 1348 Sw: *** Swn_SocketRecv: WSARecv() failed with error 10054 (0x2746)!
11/17 0:50:34.545 1348 Srv: *** SwSocket::Recv: Swn_SocketRecv() failed with error 10054 (0x2746)!
11/17 0:50:34.545 1348 C[2], LIN: iScsiConnection::receive: recvData returned 10054 (0x2746)!
11/17 0:50:34.545 1348 C[2], LIN: iScsiConnection::recvWorker: *** 'recv' thread: recv failed 10058.

I read some notes talking about transfer size, I did some test changing these parameters, but I didnt have success.
Could you help me?

Tks.

These messages are related to network interruptions.
Is it possible to send us full logs in order to investigate the issue more deeply?

Hi Oleg,

These are the configs in the iscsid.conf on the initiator side... Do you think that I need to change something?

#WBSAirback iSCSI autoconfiguration
node.startup = automatic
node.session.timeo.replacement_timeout = 120
node.conn[0].timeo.login_timeout = 15
node.conn[0].timeo.logout_timeout = 15
node.conn[0].timeo.noop_out_interval = 5
node.conn[0].timeo.noop_out_timeout = 5
node.session.initial_login_retry_max = 8
node.session.cmds_max = 128
node.session.queue_depth = 32
node.session.iscsi.InitialR2T = No
node.session.iscsi.ImmediateData = Yes
node.session.iscsi.FirstBurstLength = 262144
node.session.iscsi.MaxBurstLength = 16776192
node.conn[0].iscsi.MaxRecvDataSegmentLength = 131072
discovery.sendtargets.iscsi.MaxRecvDataSegmentLength = 32768
node.session.iscsi.FastAbort = Yes

Thank you Rodrigo,
Could you please also give more details about WBSAirback, does it have ISCSI initiator?
Is it possible to get the log from this client?

Hello Oleg,

WBSAirback is a software backup tool that runs in Linux Debian 7, but we are working in a appliance format, just the WBS has root access.
It has an Linux iSCSI initiator to access the tape drive from Starwind.
What logs would you like?

Thanks,

Rodrigo.

Hello Oleg,

Yes, I'm trying with the new parameters on iSCSI initator, but.....
- I was able to complete a backup job and a restore job once... and after I tried to write a new backup job I had the same I/O error.

I've noticed that errors always occur when a tape operation is required, such as position to the end, rewind the tape....
It is an intermittent error! Attached the new logs!

Do you know that is better to use Windows 2012?

Thanks for your help!
