Help! Why does my RT (AIX 2.2.1) create the /native directory under the root and them mount the entire root filesystem there? It never did this before, as far as I know. The commands are in the /etc/rc file. Did some LPP put these commands in and if so, why. I've installed DOS Access, Network Filesystems, and Distributed Services. Are one of these the culprit? Any help would be appreciated. db =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | Daniel P.

In an environment where you are using NFS or DS to overmount lots of files from remote systems, it's sometimes desirable to be able to have access to the files that you've mounted over. By taking all local filesystems and putting them in /native, you can always get to them if you so choose. If you normally remote mount a directory but want to have a local copy in case the server goes down, it's convenient to be able to make the local copy by issuing "cp /a/b/c/* /native/a/b/c". The /native stuff is in the base AIX 2.2 product. Another reason for it is that there's no reason for "skulker" to go cleaning up remotely mounted filesystems...if you have a file server with 50 clients, you don't need to have 50 systems banging on the server at 3am trying to clean up .bak files etc...one will do just fine. So skulker cleans up /native, not /, and thus doesn't get any remote mounted directories or files. (The "skulker" program is run by cron at 3am to perform various cleanup functions.) I'm not in AIX development, just an AIX user, and I'm speaking for myself, not for IBM. Nothing I say is accurate. :-) Sam Drake / IBM Almaden Research Center VNET: DRAKE at ALMADEN BITNET: DRAKE at ALMVMA Internet: drake@ibm.com UUCP: uunet!ibmarc!drake Phone: (408) 927-1861 IBM Tieline: 457-1861

Yes, DS does this, though why it does it for every file system I really don't know. The idea is to always give you a path to your native file systems even if you presently have them shadowed by another mount. You can ignore them, and I don't think it will hurt if you delete the mounts from your rc file, but be careful. -John -- ...................................
