Due to legacy constraints, I have a rather complicated system that is currently using Sun QFS (actually the SAM portion of it.) For a lot of reasons, I'd like to look at moving to ZFS, but would like a "sanity check" to make sure ZFS is suitable to this application.
First of all, we are NOT using the cluster capabilities of SAMFS. Instead, we're using it as a way of dealing with one directory that contains approximately 100,000 entries. The question is this: I know from the specs that ZFS can handle a directory with this many entries, but what I'm actually wondering is how directory lookups are handled? That is, if I do a "cd foo050000" in a directory with foo000001 through foo100000, will the filesystem have to scroll through all the directory contents to find foo050000, or does it use a btree or something to handle this? This directory is, in turn, shared out over NFS. Are there any issues I should be aware of with this sort of installation? Thanks for any advice or input!
