* src/storage/storage_backend_logical.c:
If a logical vol is created with multiple stripes. (e.g. --stripes 3), the "device" field of lvs output will have multiple fileds which are seperated by comma. It means the RE we write in the codes will not work well anymore. E.g. (lvs output for a stripped vol, uses "#" as seperator here):
test_stripes##fSLSZH-zAS2-yAIb-n4mV-Al9u-HA3V-oo9K1B#\ /dev/sdc1(10240),/dev/sdd1(0)#42949672960#4194304
The RE we uses:
const char *regexes[] = { "^\\s*(\\S+),(\\S*),(\\S+),(\\S+)\\((\\S+)\\),(\\S+),([0-9]+),?\\s*$" };
This patch changes the seperator into "#" to fix the problem.

Err, it seems the regexp should be changed too ... as you wrote it seems to expect ',' as the separator.
