Dear,
Do you someone know method, how can be pool converted from concatenating to
regular mirror? By mistake I replaced failed disk in pool using add not
replace, which caused me to change pool configuration.
I looking method allow me to have pool online during whole replacement
procedure.

Regards

Jan
