Hi John, Can you try to limit the memory pool iser is trying to allocate? i.e.: tgtd --iser pool_sz_mb=100 Thanks, Roi -----Original Message----- From: stgt-owner@xxxxxxxxxxxxxxx [mailto:stgt-owner@xxxxxxxxxxxxxxx] On Behalf Of John Francis Sent: Tuesday, July 23, 2013 4:32 AM To: stgt@xxxxxxxxxxxxxxx Subject: iser Issue, cannot allocate memory Hi, I have an iser target configured. When I try to log in to that target from another machine, it doesn't work, and the following appears in /var/log/message: 10:54:33 stor1 tgtd: iser_device_init(3204) iser_init_rdma_buf_pool failed 10:54:37 stor1 tgtd: iser_init_rdma_buf_pool(589) ibv_reg_mr failed, Cannot allocate memory ... I've tried fiddling with various limits but to no avail. I'm struggling to figure out if the memory limit being hit is card related of host related. Using some Mellonox cards with ib_mthca module. IPoIB seems to be working fine. It should be noted that this error occurs on initial log in to the target. -- Kind regards, John Francis www.recompute.com.au 6/38 Canterbury Rd Bankstown NSW 2200 T: (02) 9709 5775 ext 9150 Sign up to Hit Refresh, our newsletter with specials, discounts and tips, or follow us on Twitter @recompute_au. -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
