Zainstalowałem ZFS (0.6.5) na moim Centos 7 i utworzyłem również zpool, wszystko działa dobrze oprócz tego, że moje zestawy danych znikają po ponownym uruchomieniu.
Próbowałem rozwiązać ten problem przy pomocy różnych zasobów internetowych i blogów, ale nie mogłem uzyskać pożądanego rezultatu.
Po ponownym uruchomieniu, gdy wydam zfs list
polecenie, otrzymuję „brak dostępnych zestawów danych” i zpool list
daje „brak dostępnych pul”.
Po przeprowadzeniu wielu badań online, mogłem go uruchomić ręcznie importując plik pamięci podręcznej za pomocą zpool import -c plik pamięci podręcznej , ale wciąż musiałem uruchomić zestaw cachefile = / etc / zfs / zpool.cache zpool Pool przed ponownym uruchomieniem, aby zaimportować go później po ponownym uruchomieniu.
Co to jestsystemctl status zfs-import-cache
wygląda jak,
zfs-import-cache.service - Import ZFS pools by cache file

Nie jestem pewien, czy jest to znany problem ... jeśli tak, czy istnieje jakieś obejście tego problemu? być może jest to łatwy sposób na zachowanie moich zestawów danych po ponownym uruchomieniu komputera i najlepiej bez obciążenia pliku pamięci podręcznej.
