FWIW, replace the component with only one UNAVAIL line has been finished ok (UNAVAIL line disappeared together with "replacing" one); and for strange set of multiple UNAVAIL I'd overcome this by `zpool detach' all UNAVAIL components but one and then `zpool replace' the last one. What bothers me is (actually, two things, hence are): - how this situation could have place at the first time - what leads to locks requiring hard resets Unfortunately, this motherboard has dead com port, so no much luck for the serial console -- or can it be assigned to one of puc() card I have? -- Sincerely, D.Marck [DM5020, MCK-RIPE, DM3-RIPN] [ FreeBSD committer: marck@FreeBSD.org ] ------------------------------------------------------------------------ *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- marck@rinet.ru *** ------------------------------------------------------------------------
