The labels are removed by glabel as soon as something opens the = underlying provider, i. e. the disk device, for writing. Since that = process could change the part of the disk that the label information is = extracted from, the label is removed. glabel will re-taste the provider = once the process closes it again. Since you're using gpt labels, I would expect them to continue to be = available, unless zpool import somehow opens the disk devices (instead = of the partition devices).
