关于校验盘,zfs的问题

Featured Replies

    今天在网上看到关于raid5阵列的科普视频,视频里说如果在写入文件的时候断电概率下次开机阵列无法正常启动,我想问下unraid下如果写入文件时断电,下次开机会报错吗?unraid是先把文件写入数据盘等写入完了再写校验,还是和raid5一样按照块一边写入数据一边写入校验?如果unraid下写入文件时断电了,下次开机是以校验盘为准还是以数据盘为准?还有问下以后有没有支持zfs的计划,然后jbod+校验盘,类似非条带式raidz?既可以使用zfs文件系统的特性(去重快照压缩克隆),又能随时随地增加硬盘扩容或增加校验盘?还有如何跟群晖一样使用文件历史多版本?

不管是服务器还是客户端PC,都建议配置ups系统,以防止突然掉电对磁盘的冲击,而损坏硬体和数据。我的理解是,在完全奇偶校验后,阵列磁盘和校验盘实时同步数据。后续开发详情可到主版咨询开发者。
