On an 8.0-RELEASE/amd64 box, I used the net/istgt port to share iSCSI targets. The installation succeeded, but I'm now seeing write errors when using the targets: Mar 16 15:10:26 bettini istgt[1202]: istgt_iscsi.c: 640:istgt_iscsi_write_pdu: ***ERROR*** iscsi_write() failed (errno=32) Mar 16 15:10:2 6 bettini istgt[1202]: istgt_iscsi.c:3038:istgt_iscsi_op_scsi: ***ERROR*** iscsi_write_pdu() failed Mar 16 15:10:26 bettini istgt[1202]: istgt_iscsi.c:3859:istgt_iscsi_execute: ***ERROR*** iscsi_op_scsi() failed Mar 16 15:10:26 bettini istgt[1202]: istgt_iscsi.c:4337:worker: ***ERROR*** iscsi_execute() failed Mar 16 15:10:30 bettini istgt[1202]: Login from 172.31.4.12 (172.31.4.22) on iqn.2010-04.com.example.bettini:bettini4 LU5 (172.31.4.5:3260,1), ISID=23d000001, TSIH=4, CID=0, HeaderDigest=off, DataDigest=off Mar 16 15:12:10 bettini istgt[1202]: ABORT_TASK Mar 16 15:14:15 bettini istgt[1202]: ABORT_TASK Mar 16 15:16:04 bettini last message repeated 2 times The istgt documentation doesn't offer any help in pinpointing a root cause for the write errors. Writes to these targets are extremely slow, too. In case it matters, the target is a ZFS block device set up with 'zfs create -V 1T tank/bettini4'. Thanks in advance for clues on the care and feeding of iSCSI on 8.0-RELEASE. dn
