On a second thought, it does not seem to be that the db size puts the limit per se. Thread-1245::DEBUG::2011-06-22 12:33:11,118::iscsi::372::Storage.Misc.excCmd::(addiSCSIPortal) '/usr/bin/sudo -n /sbin/iscsiadm -m discoverydb -t sendtargets -p 10.35.64.10:3260 --discover' prints to stderr multiple lines like iscsiadm: Could not add/update [tcp:[hw=,ip=,net_if=,iscsi_if=default] 10.35.64.10,3260,1 iqn.2010-03.com:server.target.moran-50g-07] iscsiadm: Could not stat /var/lib/iscsi/nodes//,3260,-1/default to delete node: No such file or directory reports success (rc=0) but presumably does not updates the discoverydb. Does this make any sense? (In reply to comment #1) > iscsiadm: Could not add/update [tcp:[hw=,ip=,net_if=,iscsi_if=default] > 10.35.64.10,3260,1 iqn.2010-03.com:server.target.moran-50g-07] > iscsiadm: Could not stat /var/lib/iscsi/nodes//,3260,-1/default to delete node: > No such file or directory This is a bug in the iscsi tools. We have been chasing this in another bz (https://bugzilla.redhat.com/show_bug.cgi?id=656284), but have not been able to replicate it lately. Is this a system in red hat, and if so can I login (send me the login info to mchristi). it happened again on one of my hosts - sending the connection details to Mike. |
Created attachment 506014 [details] log Description of problem: working with the rhevm and iscsi I was trying to connect my host to my iscsi lun. I was getting an error for command: /sbin/iscsiadm -m node -T Dafna-blonds-Linux -l -p 10.35.64.10:3260 after some digging we found that we have exceeded 190 targets on the same connection and there for were unable to login. after removing the nodes under /var/lib/iscsi/nodes/*/*/default and discover again - we were able to connect again to the storage. why are we limited to 190 targets? Version-Release number of selected component (if applicable): iscsi-initiator-utils-6.2.0.872-21.el6.x86_64 How reproducible: Steps to Reproduce: 1. exceed 190 targets under same connection and try to login to lun 2. 3. Actual results: you cannot login Expected results: exceed 190 nodes limit Additional info: vdsm log which can show the error we were getting
