最近需要使用到 FSCache,今天调研一下FS-Cache,主要记录一些索引,方便以后查阅:
RedHat 文档:https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/storage_administration_guide/ch-fscache (此文档讲解较为详细)
内核社区文档:https://www.kernel.org/doc/Documentation/filesystems/caching/fscache.txt
FS-Cache: A Network Filesystem Caching Facility:https://people.redhat.com/dhowells/fscache/FS-Cache.pdf
NFS 相关,请阅读:https://www.cnblogs.com/xuyaowen/p/NFS_install.html (之前写的关于nfs 的内容)
