Hi, I have multinode Openstack Icehouse setup. I am trying to attach a volume of 100GB through cinder service. But I am not able to do that and it is failing.
When I checked "/var/log/messages" I got the following error while attaching the volume from the instance. Nov 11 07:22:34 network-Blade3 sudo: cinder : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/cinder-rootwrap /etc/cinder/rootwrap.conf tgt-admin --force --delete iqn.2010-10.org.openstack:volume-ed123cfc-17f8-4fc6-bad4-24aea78407d2 Nov 11 07:22:34 network-Blade3 sudo: cinder : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/cinder-rootwrap /etc/cinder/rootwrap.conf tgt-admin --show *Nov 11 07:22:34 network-Blade3 kernel: [945233.808908] tgtd[14087]: segfault at 0 ip 00007fbb0b8e5b46 sp 00007fffb2591f48 error 4 in libc-2.11.3.so <http://libc-2.11.3.so>[7fbb0b7d3000+16e000]* As far as I have understood, Cinder uses tgtd service as iscsi back end to expose the volumes to the VMs running on compute nodes. There will be a target created by tgtd for every volume created by cinder. Compute nodes will start an iscsi session to this target while attaching the volume and also it closes the session while detaching. When I further debug this issue by attaching tgtd service to gdb. Segmentation fault is raised in following method: Program received signal SIGSEGV, Segmentation fault. *0x00007f082caa5b46 in __strcmp_sse42 () from /lib64/libc.so.6* Can anyone tell me how can I fix this? BR, Varun
