This error did indeed happen during discovery (against an OpenSolaris iSCSI target): # dpkg -l open-iscsi ... ii open-iscsi 2.0.865-1 High performance, transport independent iSCS # iscsiadm -m discovery -t sendtargets -p 10.100.101.51 iscsiadm: buffer size 32768 too small for data length 32768 > In http://www.open-iscsi.org/bits/open-iscsi-2.0-865.15.tar.gz you can set: > > # To specify the maximum number of data bytes the initiator can receive > # in an iSCSI PDU from a target during a discovery session, edit the > # following line. > # > # The value is the number of bytes in the range of 512 to (2^24-1) and > # the default is 32768 > # > discovery.sendtargets.iscsi.MaxRecvDataSegmentLength = 32768 > > Some targets have a limit of 64K and there is a bug where we do not > handle multiple pdus correctly. > > In http://www.open-iscsi.org/bits/open-iscsi-2.0-869-rc2.tar.gz you can > set the same value and the pdu handling should be fixed. This works a lot better: # /open-iscsi-2.0-869-rc2/sbin/iscsiadm -m discovery -t sendtargets -p 10.100.101.51 | wc 889 1778 84341 Thanks for providing a solution so quickly. Has it already been decided when open-iscsi version 2.0-869 will be released ?
