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.
Hum, looking at the current code now I see .poolOptions = { .flags = VIR_STORAGE_BACKEND_POOL_SOURCE_NAME, .formatFromString = virStorageBackendLogicalPoolFormatFromString, So there is an initialization of the field. It's unclear to me if the two should be OR'ed, or should be kept as-is, if we have the pool name do we need to provide the pool device then ? I get a bit confused now.
After this problem was memory corruption cause by miscalculating the size of vgcreate command line :-).
Whoops !! :-) That one applied cleanly. So at least I'm commiting this part. thanks ! Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel@veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
