Centos 7에 ZFS (0.6.5)를 설치했으며 zpool도 만들었습니다. 재부팅시 데이터 세트가 사라진다는 사실과는 별개로 작동합니다.
다양한 온라인 리소스와 블로그를 사용 하여이 문제를 디버깅하려고했지만 원하는 결과를 얻지 못했습니다.
재부팅 후, 나는이 실행할 때 zfs list명령을 내가 얻을 “사용 가능한 데이터 셋” 하고 zpool list있습니다 “아니오 풀 가능”
온라인으로 많은 연구를 수행 한 후, 나는 그것을 수동으로 사용하여 캐시 파일을 가져 와서 작업을 만들 수 는 zpool 가져 오기 -c과 CacheFile을 하지만, 여전히 재부팅 후에 나중에 가져 오기 위해 재부팅 전에 zpool set cachefile = / etc / zfs / zpool.cache 풀을 실행 해야했습니다.

이것은 무엇입니까systemctl status zfs-import-cache 처럼 보인다

이것이 알려진 문제인지 확실하지 않습니다. 그렇다면, 이에 대한 해결 방법이 있습니까? 재부팅 후 캐시 파일의 오버 헤드없이 데이터 세트를 유지하는 쉬운 방법 일 것입니다.
