If you are interested in a non-GUI Perl Code solution that will slice-n-dice your storage data in just about any way possible, you might take a look at yadu (Yet Another du) which can be found at: http:/www.komar.org/ -> Misc. Tech Stuff -> yadu alek P.S. If you want to "stretch" your data, you might also take a look at the "Longest Car on the Internet" which is also there ... or simply type "longest car" into Google and go from there! ;-)

Hello Toasters, I'm looking for a solution to manage the disk space usage on the storage environment (Windows NT/2000, Netapp Filer, SAN - Sun, Hitachi). Need to track who is the 'disk hog', duplicate files, keep historical data, etc.. I'm sure there's more to it. Anyways, have not dealt with any storage management solution so any suggestion will help. thanks, Marcus Bui

CIFS getattr load
by Todd C. Merrill 11 Mar '03

11 Mar '03

Instead of standing at a crossroads or a fork in the road, I'm standing in an open field, and need somebody to point me in a direction... My filers are showing loads and loads of CIFS getattr operations, on the order of 80% of the CIFS traffic, which is 80-90% of the total NFS and CIFS traffic. Finding out why this is so, or alleviating it or reducing it so the load on the filers goes down, is my goal. The filers are used in a software development environment, in an automated testing environment (generally no interactive usage by people). The CIFS/getattr load is most imbalanced not when a software build is happening but while testing suites are run. On the order of only 10 Windows clients (generally Win2k) can nearly cripple an F840. So, at this point, any WAG's are welcome. Do directories with large numbers of files stress the getattr operations? Has anyone run across any applications that are very "chatty" with filers? Has anyone run into any bugs (with ONTAP or with Windows) that might show such a symptom? Perhaps the application mix we are running is just this way, but something in my gut tells me something is amiss. I have a sniffer available, but before I get to that detail, I was hoping to mine the wisdom of this list, to approach this vague problem armed with some good ideas. Until next time...

ClearCase 5.x on NetApp, mixed NFS/CIFS setup issues
by John Stoffel 11 Mar '03

11 Mar '03

Hi all, We're starting to roll out a new ClearCase instance here, and we're taking advantage of the support between Rational and Network Appliance to put all the data onto our F760 running 6.3.1 with both NFS and CIFS licenses. The VOB and View servers just run the lock managers and other processes. The clients (NT and Linux) just access the storage directly from the NetApp after getting the info they need from the VOB/View servers. We've setup a seperate volume for ClearCase (CC) VOBs and VIEWs with mixed security settings. The problem is that running as root on one of the ClearCase servers, we cannot remove a file that was created by a user running on a PC with CC client software. Our infrastructure is pretty simple, with just one NIS domain and one NT domain to work with. But because our corporate IT group won't give us a short group name in the Win2K domain, we're forced to use the unix username of 'mss-vobadm' with an NT username of NA05\sa106068ccalbd. We've got a usermap.cfg as shown below. Does anyone have any hints on how we can fix this up, or track down the proper setup for this environment? NA05\sa106068ccalbd => mss-vobadm NA05\sa106068ccalbd <= root And we've tried to use the following cifs options: > options cifs cifs.audit.enable off cifs.audit.file_access_events.enable on cifs.audit.logon_events.enable on cifs.audit.logsize 524288 cifs.audit.saveas /etc/log/adtlog.evt cifs.bypass_traverse_checking on cifs.comment cifs.guest_account cifs.home_dir cifs.home_dir_namestyle cifs.idle_timeout 1800 cifs.max_mpx 50 cifs.netbios_aliases cifs.netbios_over_tcp.enable on cifs.nfs_root_ignore_acl on cifs.oplocks.enable on cifs.oplocks.opendelta 8 cifs.per_client_stats.enable off cifs.perm_check_ro_del_ok on cifs.perm_check_use_gid on cifs.restrict_anonymous.enable off cifs.save_case on cifs.scopeid cifs.search_domains cifs.show_snapshot off cifs.shutdown_msg_level 2 cifs.sidcache.enable on cifs.sidcache.lifetime 1440 cifs.snapshot_file_folding.enable off cifs.symlinks.cycleguard on cifs.symlinks.enable on cifs.trace_login off cifs.wins_servers X,Y,Z Along with the following for share security: tswtoast> cifs shares Name Mount Point Description ---- ----------- ----------- vobstg /vol/ccvol/vobstg everyone / Full Control mss-ccase{g} / Full Control mss-eng{g} / Full Control NA05\sa106068ccalbd / Full Control viewstg /vol/ccvol/viewstg everyone / Full Control mss-eng{g} / Full Control NA05\sa106068ccalbd / Full Control clearcase /vol/vol0/clearcase everyone / Full Control Any hints or help would be appreciated.

CIFS shares and auditing
by Geoff Hardin 11 Mar '03

11 Mar '03

Toasters, Let me start by stating that I am a UNIX admin and I administer my filers strictly by command line or scripts we've written. Most of our data is shared via NFS with a few CIFS shares setup on only a couple filers. That said, a user want a log of who accesses his share and which files were viewed/changed. Reading the man pages and the admin guide for ONTAP 6.1, it appears that the best/only solution is the cifs.audit.enable option. I have enabled this per the instructions in the System Administrators Guide (http://now.netapp.com/NOW/knowledge/docs/ontap/rel61r1/html/sag/cifs36.htm#…). According to this document, you can turn auditing on in five simple steps. My problem is with step number 4: "Activate access auditing for individual files and directories according to your Windows documentation." Since I'm a UNIX admin, I don't understand the Windows aspect of filer administration. I tried getting our NT admins to take a look at it, but they say they can't set the file and directory auditing on the filer using the User Manager tool (the menu items under the Policies menu are unselectable). I have tried creating a non-root, administrative account using the useradmin console command, but that left them with fewer rights on the filer than as the domain admin. Any help or pointers would be greatly appreciated. Thanks, Geoff Hardin geoff.hardin(a)dalsemi.com This space is for rent in order to increase company revenue.
