Description of problem:
when vdsm attempts to add a new record to the iscsi database it fails with the following error, and rc = 3:
iscsiadm: Error while adding record: no available memory.

The commands that were run:
/usr/bin/sudo -n /sbin/iscsiadm -m discoverydb -t sendtargets -I default -p <server> --discover (succeeds)

/usr/bin/sudo -n /sbin/iscsiadm -m node -T <target> -I default -p <server> --op=new (fails)

Version-Release number of selected component (if applicable):
vdsm-4.12.0-72.git287bb7e.el6ev.x86_64
iscsi-initiator-utils-6.2.0.873-5.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Add second host to existing iscsi datacenter on rhevm 

Actual results:
Host becomes non-operational due to error when connecting to storage

Comment 5 Chris Leech 2013-08-27 21:01:05 UTC
This looks like a regression caused by a problem in the fix for #884427.

The GLOB_NOMATCH return code is being passed along in idmb_rec_write_old, and later taken to be ISCSI_ERR_NOMEM as they are the same value.  A no-match in glob here is not an error, and the return code needs to be reset to 0.

Comment 12 Bruno Goncalves 2013-09-12 13:59:46 UTC
Reproduced the same issue on iscsi-initiator-utils-6.2.0.873-6

iscsiadm -m discoverydb -t sendtargets -I default -p <server> --discover
[  OK  ] iscsid: [  OK  ]

[root@storageqe-17 ~]# iscsiadm -m node -T <target> -I default -p <server> --op new
iscsiadm: Error while adding record: no available memory


----

Fixed on iscsi-initiator-utils-6.2.0.873-8.el6

iscsiadm -m discoverydb -t sendtargets -I default -p <server> --discover
[  OK  ] iscsid: [  OK  ]

[root@storageqe-17 ~]# iscsiadm -m node -T <target> -I default -p <server> --op new
New iSCSI node [tcp:[hw=,ip=,net_if=,iscsi_if=default] <server>,3260,-1 <target>] added
