Hi, I have old 11-STABLE as an iSCSI server, but out of the blue I encountered weird problem: only 579 targets can be created. I mean, I am fully aware that the out-of-the-box limit is 128 targets, with is enforced by the CTL_MAX_PORTS define, and I've set it to 1024 (and of course rebuilt and installed a new kernel), but when I add more that 579 targets I start to get the protocol errors: Sep 22 10:16:48 san1 ctld[8657]: 10.0.3.127 (iqn.1991-05.com.microsoft:worker296): protocol error: received invalid opcode 0x4 Sep 22 10:16:48 san1 ctld[8658]: 10.0.3.127 (iqn.1991-05.com.microsoft:worker296): protocol error: received invalid opcode 0x46 Sep 22 10:17:31 san1 ctld[8746]: 10.0.3.127 (iqn.1991-05.com.microsoft:worker296): protocol error: received invalid opcode 0x4 Sep 22 10:17:31 san1 ctld[8747]: 10.0.3.127 (iqn.1991-05.com.microsoft:worker296): protocol error: received invalid opcode 0x46 Sep 22 10:19:58 san1 ctld[9190]: 10.0.3.127 (iqn.1991-05.com.microsoft:worker296): protocol error: received invalid opcode 0x4 Sep 22 10:19:58 san1 ctld[9191]: 10.0.3.127 (iqn.1991-05.com.microsoft:worker296): protocol error: received invalid opcode 0x46 Sep 22 10:21:33 san1 ctld[9518]: 10.0.3.127 (iqn.1991-05.com.microsoft:worker296): protocol error: received invalid opcode 0x4 Sep 22 10:21:33 san1 ctld[9519]: 10.0.3.127 (iqn.1991-05.com.microsoft:worker296): protocol error: received invalid opcode 0x46 So, the question is - is it possible to have more than 579 targets and if yes - how can this be achieved ? Right now I'm experimenting with extending luns, not targets. One may think that I am merey greedy, but the thing is, I really have hundreds of initiatorsm and it's just logical to have as many targets as I do. Thanks. Eugene.
