Erlang : Mnesia : Is it safe to remove files with prefix _fs?
原标题:

I have a couple of files in mnesia directory, like

fs_my@node_14585_1263_545605_962084.273
fs_my@node_14702_1263_545842_879762.273 
fs_my@node_14585_1263_545605_962084.290 
... 

Can I remove them (because it is big files) without risk to lose data?

Why does these files apear? What are these files for? Is it safe to remove them?

最佳回答

See http://www.erlang.org/doc/man/file_sorter.html

So without looking into the files, I would say that 1.+4. Yes, you can remove them, but first give it a try, as Zed said. 2.+3. They are temporary files used for sorting and should have been removed. """[...] Temporary files are deleted unless some uncaught EXIT signal occurs."""
