Re: DRBD + ...
Попробовал раздел с репозиторием перевести на DRBD.
Расширил до 250 Гб.
Синхронизировалось очень медленно, около 5 часов:
root@cluster-data-1:~# drbd-overview
1:repository SyncSource Primary/Secondary UpToDate/Inconsistent C r-----
[===============>....] sync'ed: 80.7% (49332/254652)Mfinish: 1:11:09
speed: 11,820 (11,480) K/sec
Мало того, для DRBD надо создавать метаданные.
Есть ли вариант без этого?
Т.е., если один диск упадёт, его было возможно легко заменить (просто выключив
сервер, вынув испорченный диск и вставив новый)?
И, если одна машина упадёт, всё работало бы и на одной второй?
Вкратце, что из ресурсов есть, на данный момент (cluster-gate-1 почти идентичен
cluster-gate-2):
