Установил в домашний сервер контроллер с модулем AFM-600. На сервере работает Proxmox 6.2.
Включил кэширование записи командой
arcconf SETCACHE 1 LOGICALDRIVE 0 wbb. Из-за глюка ИБП несколько раз сервер выключался нештатно, и каждый раз бьются данные на диске (таблицы MySQL InnoDB, LVM встаёт в ошибку, не говоря уже об ошибках на EXT4). Что это, нерабочий кэш, или я что-то не так настроил?
Вывод
arrconf getconfig 1:
