Hi, Are ZFS ARC memory pages relocatable so if UE or too many CE happens in a given page being used by ZFS ARC it will be nicely handled in most cases...? Would data in a page be automatecally re-read from a dataset if the page wasn''t dirty or would it be just gone from cache and page would be retired? What if data was dirty? or are arc mem pages non-relocatable and system would just panic...? -- Robert Milkowski http://milek.blogspot.com
