The following message is logged when trying "dd if=3D/dev/da0 of=3D/dev/null bs= =3D1m count=3D1" on the client after making the target available: May 31 19:43:46 mizar kernel: (da0:iscsi1:0:0:0): Capacity data has changed However, I then proceeded to remove the target from the configuration. On t= he client this leads to the message May 31 17:44:41 mizar iscsid[4380]: hal.xyzzy (iqn.1995-06.xyzzy.hal:disk1): target returned error: Not found May 31 19:44:41 mizar kernel: WARNING: hal.xyzzy (iqn.1995-06.xyzzy.hal:dis= k1): connection error; reconnecting May 31 19:44:41 mizar iscsid[4220]: child process 4380 terminated with exit status 1 But device da0 on the client still exists. If I now do dd if=3D/dev/da0 of=3D/dev/null bs=3D1m count=3D1" on the client again, I get a non-interrup= tible hang until I make the target available again, and even then the hang only termin= ates after a timeout of 60 seconds: May 31 19:45:42 mizar iscsid[4387]: hal.xyzzy (iqn.1995-06.xyzzy.hal:disk1): target returned error: Not found May 31 19:45:42 mizar kernel: WARNING: hal.xyzzy (iqn.1995-06.xyzzy.hal:dis= k1): login timed out after 61 seconds; reconnecting May 31 19:45:42 mizar iscsid[4220]: child process 4387 terminated with exit status 1 May 31 19:46:43 mizar kernel: WARNING: hal.xyzzy (iqn.1995-06.xyzzy.hal:dis= k1): login timed out after 61 seconds; reconnecting The dd then succeeds. --=20 You are receiving this mail because: You are the assignee for the bug.=
