Centos 7'ye ZFS (0.6.5) yükledim ve ayrıca bir zpool oluşturdum, veri kümelerimin yeniden başlatıldığında kaybolması dışında her şey iyi çalışıyor.
Çeşitli çevrimiçi kaynaklar ve bloglar yardımıyla bu sorunu ayıklamaya çalışıyorum, ancak istenen sonucu alamadım.
Yeniden başlattıktan sonra, ben kesilirken zfs list
komutu alıyorum "hiçbir veri kümeleri" ve zpool list
verir "hayır havuzları mevcut"
çevrimiçi çok araştırma yaptıktan sonra, ben elle kullanarak önbellek dosyası içe aktararak işe yapabiliriz zpool ithalat -c CacheFile ama yine de daha sonra yeniden başlattıktan sonra almak için yeniden başlatmadan önce zpool set cachefile = / etc / zfs / zpool.cache Havuzu çalıştırmak zorunda kaldı .
Bu nedirsystemctl status zfs-import-cache

Bunun bilinen bir sorun olup olmadığından emin değilim, eğer evet ise, bunun için bir çözüm var mı? veri kümelerimi yeniden başlattıktan sonra ve tercihen bir önbellek dosyasının yükü olmadan korumanın kolay bir yolu olabilir.
