Добрый день.

Столкнулся с пренеприятной проблемой.

В общем Фря крутится на софтверном зеркале gmirror
на днях по причине наличия беда вывалился диск из массива (ad0 - винт WD 160 GB)

Винт проверил MHDD - по адресу 47208092 обнаружен один бед
стер диск командой MHDD erase - бед пропал, т.е. это был софтверный а не физический бед

еще раз проверил винт MHDD - поверхность диска чистая, - все ОК

вернул диск на место - массив не синхронизируется
smartd сыпет на мыло сообщения:

ситуация тупиковая - виртуальный бед, которого фактически нет, чтобы исправить(реалокейтом например), но он (какбы) есть и винт поэтому в зеркало не пускает


Помогите, пожалуйста, подскажите, как решить эту проблему
