Hello,
I am trying to setup a host for a seperate oVirt engine/node environment
(version 3.1). I managed to get my host up and running and active in my Data
Center. I managed to create 4 storage domains on that host. 2 Data domains and
1 ISO domain and one Export domain.
I am successful in attaching the ISO/Export/smaller Data domain to my Data
Center. The web admin interface is indicating they are active. I activated my
smaller test Data domain because I was having some issues earlier getting my
storage attached. I worked through those issues and now I want to attach my
actual Data storage so I can detach the test one. Whenever I attempt to attach
the storage I get an error message and when I look in the vdsm log I see the
following:

Which seems to indicate the disk is full. Which is not the case as this is a
brand new machine with a fresh install and a 1T drive in it. The error does
point to sanlock so when I look at the sanlock log I see this:
2013-01-17 16:55:22-0500 4161 [3187]: r12 cmd_acquire 3,14,3830 invalid
lockspace found -1 failed 0 name 807c2e91-52c3-4779-9ebb-771b96bf5a4c
I googled around for that particular error message and I couldn't find anyone
with any suggestions as to the source of that problem.
Could someone please give me a pointer of where to look or help me debug the
issue.
Thanks,
Alexander
