Hi Mike,Agreed - but this can be avoided with judicious use of quota management- hence my mention"Any other issues are about configurationand administration and are easy to deal with if you experience what you'redoing."Having all CIFS shares and/or NFS exports coming from withing quota'dqtrees is something I would tend to do and advise anyway along withSNMP traps for warning thresholds etc. but admittedly it only takessomeone to slack off and start putting data outside those qtrees andthen you do run the risk of a full rootvol. Hence why a small FlexVoldedicated to root is the way to go if you're able to run newer versionsof OnTap. Unfortunately in the situation under discussion it's an old F760 with apre-7 version of version of OnTAP and no support contract therefore noway to (legally) grade the OS.

September 04. 2007 11:52 PMTo: Subject: RE: No spare disks for rootHi Coolhand,Why do you conclude that having the small amount of root info in the /etcdirectory in the same volume as your data is a problem?Having all the disks on the root volume isn't really a problem. Iinstalled many filers in the days before NetApp started recommendingpeople dedicate two disks for the root volume and never had anyissueswith using the root vol for data. In fact most of my customers forfiveyears or so when I worked as an SE for a NetApp reseller user vol0 fordata such as user homedirs and workgroup directories and no-one evenreally thought about it. A second volume is needed only where you want to change volume leveloptions ("minra". "noatimeupdate" etc) or undergo a displace volume fordatabase tablespace files or iSCSI/FCP LUN's. Qtree quotas can dealwithmost space restriction requirements. Also you ordain want multiplevolumesif you're doing bare-metal backups ("snapmirror to attach") or DRreplication for application data volumes with differing RTO's/RPO's. The only real favor to be gained by dedicating disks for the rootvolume in earlier versions (before Ontap 7 with FlexVols with it'sobvious additional benefits) is that the disks for a dedicatednon-rootdata volume can be moved as a set to another filer and that datavolumeis then available on the second filer as a foreign volume withouthavingto do extra steps after kick. Any other issues are about configurationand administration and are easy to broach with if you experience what you'redoing. The obvious major disadvantage to dedicating two disks for the rootvolume is the vast waste of storage space* at least in Ontap 7 withFlexVol you can undergo a dedicated root vol for administrativeseparationpurposes without wasting space although you now if you act physicaldisk sets all volumes in the same add up are visible on the fileryoumove the disks to. The administrative issues you mentioned are easily fixed. Just rerunCIFS setup and reconfigure to furnish yourself access. Or if you don'twantto change an existing domain configuration you can modify the securityinformation in /etc via the "rdfile" and "wrfile" commands withcut-and-paste i e add the SID for the windows user to the"Administrators" group in lclgroups cfg and/or add a mapping for theWindows user to "root" in usermap cfg. Another thing to analyse is the security style on the volume and thepermissions on the /etc directory. One handy thing to do is make the /etc directory a qtree:Filer> qtree act etcnewCopy the contents of /etc to /etcnewRename /etc to /etcold (from Windows)call /etcnew to /etcThen you can delete the /etcold directory or keep it there for abackup. The advantage of doing this is it allows you to displace out /etc forquota management purposes. Also for a CIFS-only filer in a largedomainenvironment where you be to circumscribe access to /etc to only specificfiler admins you can set the security call on /etc to "unix" thencreate mappings to "root" in usermap cfg for specific Windows adminaccounts while locking the rest of the "domain admins" out of /etc. Youcan alter the UNIX permissions on the new /etc qtree using the freeSecureShare Access". I've done this on a couple of CIFS-only siteswherethey had lots of domain admins but wanted only specifically trainedfiler admins to undergo access to /etc and it works a treat. Hope this helps.
