The command is being rejected by the target because the target does not support it. >> [ 748.430030] connection1:0: detected conn error (1020) >> [ 754.695618] connection1:0: detected conn error (1021) >> >> and the co9nnection is broken. >> Any idea what could be the reason? >> >> Thank you. >> >> (the storage I connect to is a Dell MD3200i storage, no issues before of >> this kind). > > Ok, some more information: > > Error appeared in Debian with kernel linux-image-4.3.0-0.bpo.1-amd64 > (jessie-backports) and open-iscsi 2.0.873+git0.3b4b4500-14 (also > appeared with open-iscsi 2.0.873+git0.3b4b4500-8+deb8u1). > > Error is gone on debian jessie kernel 3.16+63. > > FS is a ext4 on storage. > I think this was caused due to newer ext4/block layer code sending a command the storage did not support in newer kernels by default or maybe the block/SCSI layer changed the format being used. I want to say it was discard related, but I cannot remember for sure. Could you take a tcpdump or writeshark trace when you run this test, so I can see what SCSI command we are failing on? Also, is there anything in the MD320 logs about a command being rejected because it is not supported? -- You received this message because you are subscribed to the Google Groups "open-iscsi" group.
