Hello, thanks for quick reply. During weekend I did backups on the iscsi-device with not one single error on kernel 2.6.22.

These errors posted earlier resulting from simply copying a dvdimage from a local logical volume on SATA-Drives to a logical volume on the iscsi-device. Normal usage is to do backups by rsync (dirvish) to this device, which are very slow due to timeouts (normal rsync linux backups via ssh and the windows-filesystems by local rsyncing cifs-mounts). Results stay the same. The errors only happen when copying to the iscsi-device. Restoring of data from iscsi to local volumes works great without errors on the 2.6.24 -Kernel. Another effect is backups are slow and no keyboard interaction is possible during these timeouts. > > When you were using 2.6.22-3-686, were you also using the open-iscsi deb > package 2.0.869.2-2 or was it a older version. We just boot from the former 2.6.22 -Kernel. dpkg -l |grep iscsi ii open-iscsi 2.0.869.2-2 > > On the broken setup could you run > > iscsiadm -m session -P 3 > > and send all the output? iscsiadm -m session -P 3 iSCSI Transport Class version 2.0-724 iscsiadm version 2.0-869 Target: iqn.2002-10.com.infortrend:raid.sn7457154.20 Current Portal: 192.168.7.227:3260,1 Persistent Portal: 192.168.7.227:3260,1 ********** Interface: ********** Iface Name: default Iface Transport: tcp Iface Initiatorname: iqn.1993-08.org.debian:01.b75ebc4b5f99 Iface IPaddress: 192.168.7.2 Iface HWaddress: default Iface Netdev: default SID: 1 iSCSI Connection State: LOGGED IN iSCSI Session State: Unknown Internal iscsid Session State: NO CHANGE ************************ Negotiated iSCSI params: ************************ HeaderDigest: None DataDigest: None MaxRecvDataSegmentLength: 131072 MaxXmitDataSegmentLength: 65536 FirstBurstLength: 65536 MaxBurstLength: 262144 ImmediateData: Yes InitialR2T: No MaxOutstandingR2T: 1 ************************ Attached SCSI devices: ************************ Host Number: 5 State: running scsi5 Channel 00 Id 0 Lun: 0 Attached scsi disk sdc State: running scsi5 Channel 00 Id 0 Lun: 1 Attached scsi disk sdd State: running scsi5 Channel 00 Id 0 Lun: 2 Attached scsi disk sde State: running scsi5 Channel 00 Id 0 Lun: 3 Attached scsi disk sdf State: running scsi5 Channel 00 Id 0 Lun: 4 Attached scsi disk sdg State: running scsi5 Channel 00 Id 0 Lun: 5 Attached scsi disk sdh State: running scsi5 Channel 00 Id 0 Lun: 6 Attached scsi disk sdi State: running greets Michael > > > -- Michael Kindermann Systemadministrator HandyGames www.handy-games.com GmbH i_Park Klingholz 13 97232 Giebelstadt Germany Tel: +49 (0) 9334 9757 - 35 mail:[EMAIL PROTECTED] --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
