Hi All!
I came across some problems trying to create a new LVM-based storage
pool using this config
<pool type="logical">
<name>test_vg</name>
<source>
<device path="/dev/sdb1"/>
</source>
<target>
<path>/dev/test_vg</path>
</target>
</pool>
Volume group did not previously exist so I did
virsh pool-define <above.xml>
virsh pool-build test_vg
pool-build failed since the backend logical storage driver does not have
VIR_STORAGE_BACKEND_POOL_SOURCE_DEVICE set in flags. Without this flag
set, the device element is never parsed in virStoragePoolDefParseDoc()
(storage_conf.c), causing pvcreate to fail since no physical volume is
specified.
Yep, mea-culpa. I went through so many re-designs & re-writes of the
LVM modelling I guess I forgot to test pool creation in the final
code :-(
After this problem was memory corruption cause by miscalculating the
size of vgcreate command line :-).
Opps, not so much mis-calculating, as not calculating at all !.
ACK to this patch
