you just have to close them then:

Code:
#!/bin/bash

{
	exec 62>&-
	exec 63>&-
	lvcreate -s -l 100%FREE -n var-data-snapshot vg00/var-data
} 2> >(logger -t "loggingtest.crit") 1> >(logger -t "loggingtest.info")

sync &
wait

{
	exec 62>&-
	exec 63>&-
	lvremove -f vg00/var-data-snapshot
} 2> >(logger -t "loggingtest.crit") 1> >(logger -t "loggingtest.info")
