Hi Tomo, I have problems which OTOH don't seem to be related to this patch, but OTOH don't allow me to declare the latest code to work... First, with TCP, I can't login, the initiator complains and prints the "Could not create connection due to crc32c loading error. Make sure the crc32c module is built as a module or into the kernel" famous crc32 load error, but the RHEL 5.3 config file has it all in place (info below), I am quite sure its RTFM but I don't find the "M" that would tell me what I am doing wrong... Next, with iSER, I can't write with disktest but can with dd (bs is null) > # dd if=/dev/zero of=/dev/sdi bs=1k count=1024 > 1024+0 records in > 1024+0 records out > 1048576 bytes (1.0 MB) copied, 0.042389 seconds, 24.7 MB/s > # disktest -PT -T30 -h1 -K1 -B32k -ID /dev/sdi -D 0:100 > | 2009/09/17-09:54:42 | INFO | 27601 | v1.1.12 | /dev/sdi | Balancing percentage between reads and writes > | 2009/09/17-09:54:42 | START | 27601 | v1.1.12 | /dev/sdi | Start args: -PT -T30 -h1 -K1 -B32k -ID /dev/sdi -D (-N 2000) (-r) (-c) (-p r) (-L 31) > | 2009/09/17-09:54:42 | INFO | 27601 | v1.1.12 | /dev/sdi | Starting pass > | 2009/09/17-09:54:42 | ERROR | 27601 | v1.1.12 | /dev/sdi | Write failed: seek 1, lba 1280 (0x500), got = -1, asked for = 32768 > | 2009/09/17-09:54:43 | STAT | 27601 | v1.1.12 | /dev/sdi | Read throughput: 0.0B/s (0.00MB/s), IOPS 0.0/s. > | 2009/09/17-09:54:43 | STAT | 27601 | v1.1.12 | /dev/sdi | Total read throughput: 0.0B/s (0.00MB/s), IOPS 0.0/s. > | 2009/09/17-09:54:43 | END | 27601 | v1.1.12 | /dev/sdi | Test Done (Failed) Or > # grep -i crc /boot/config-2.6.18-128.el5 > CONFIG_CRYPTO_CRC32C=y > CONFIG_CRC_CCITT=m > CONFIG_CRC16=m > CONFIG_CRC_ITU_T=m > CONFIG_CRC32=y > CONFIG_LIBCRC32C=y # iscsiadm -m node --target tgt-xxx # BEGIN RECORD 2.0-868 node.name = tgt-xxx node.tpgt = 1 node.startup = automatic iface.hwaddress = default iface.iscsi_ifacename = default iface.net_ifacename = default iface.transport_name = tcp node.discovery_address = 10.10.5.62 node.discovery_port = 3260 node.discovery_type = send_targets node.session.initial_cmdsn = 0 node.session.initial_login_retry_max = 4 node.session.cmds_max = 128 node.session.queue_depth = 32 node.session.auth.authmethod = None node.session.auth.username = <empty> node.session.auth.password = <empty> node.session.auth.username_in = <empty> node.session.auth.password_in = <empty> node.session.timeo.replacement_timeout = 120 node.session.err_timeo.abort_timeout = 15 node.session.err_timeo.lu_reset_timeout = 30 node.session.err_timeo.host_reset_timeout = 60 node.session.iscsi.FastAbort = Yes node.session.iscsi.InitialR2T = Yes node.session.iscsi.ImmediateData = No node.session.iscsi.FirstBurstLength = 262144 node.session.iscsi.MaxBurstLength = 16776192 node.session.iscsi.DefaultTime2Retain = 0 node.session.iscsi.DefaultTime2Wait = 2 node.session.iscsi.MaxConnections = 1 node.session.iscsi.MaxOutstandingR2T = 1 node.session.iscsi.ERL = 0 node.conn[0].address = 10.10.5.62 node.conn[0].port = 3260 node.conn[0].startup = automatic node.conn[0].tcp.window_size = 524288 node.conn[0].tcp.type_of_service = 0 node.conn[0].timeo.logout_timeout = 15 node.conn[0].timeo.login_timeout = 15 node.conn[0].timeo.auth_timeout = 45 node.conn[0].timeo.noop_out_interval = 5 node.conn[0].timeo.noop_out_timeout = 5 node.conn[0].iscsi.MaxRecvDataSegmentLength = 131072 node.conn[0].iscsi.HeaderDigest = None node.conn[0].iscsi.IFMarker = No node.conn[0].iscsi.OFMarker = No # END RECORD -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
