缓存池两块固态,容量是怎么算的,为啥我的容量不能增加

Featured Replies

如图,我添加了一个缓存池,插槽2,然后将两块512G的固态放进去启动阵列,然后我lsblk命令查看,cache的容量只有512G,我其实是想增大缓存池的容量,到1G,有办法吗,还是两块缓存盘512G互作备份了WX20230628-093723@2x.thumb.png.6526cd6964ef9fb7a25ce438994cb2f8.png

挂载后的容量情况

缓存池两块硬盘默认是 RAID1 模式, 先停止阵列,然后更新下缓存池的配置,改成RAID0就行

你好,谢谢,但是cache pool我没有看到raid0和raid1的设置诶,只有slot插槽选几块而已

需要擦除重新格式化,就可以raid0了

cache pool默认还是保存了很多重要数据的,比如docker的container里具体配置,vm的东西等等,不建议改raid0。 当然不在意数据丢失的话随意

是的,主要是容量感觉重要一些,新固态稳定性还是有的,应该没啥太大问题

不需要停止阵列的

然后选择你想要的模式即可,它可以一边运行一边改变raid模式的.
