RE: No spare disks for root
by Alan McLachlan 05 Sep '07

05 Sep '07

Hi Coolhand, Why do you feel that having the small amount of root info in the /etc directory in the same volume as your data is a problem? Having all the disks on the root volume isn't really a problem. I installed many filers in the days before NetApp started recommending people dedicate two disks for the root volume, and never had any issues with using the root vol for data. In fact most of my customers for five years or so when I worked as an SE for a NetApp reseller user vol0 for data such as user homedirs and workgroup directories and no-one even really thought about it. A second volume is needed only where you want to change volume level options ("minra", "noatimeupdate" etc), or have a separate volume for database tablespace files or iSCSI/FCP LUN's. Qtree quotas can deal with most space restriction requirements. Also you will want multiple volumes if you're doing bare-metal backups ("snapmirror to tape") or DR replication for application data volumes with differing RTO's/RPO's. The only real advantage to be gained by dedicating disks for the root volume in earlier versions (before Ontap 7 with FlexVols with it's obvious additional benefits) is that the disks for a dedicated non-root data volume can be moved as a set to another filer and that data volume is then available on the second filer as a foreign volume without having to do extra steps after boot. Any other issues are about configuration and administration and are easy to deal with if you know what you're doing. The obvious major disadvantage to dedicating two disks for the root volume is the vast waste of storage space* at least in Ontap 7 with FlexVol you can have a dedicated root vol for administrative separation purposes without wasting space, although you now if you move physical disk sets all volumes in the same aggregate are visible on the filer you move the disks to. The administrative issues you mentioned are easily fixed. Just rerun CIFS setup and reconfigure to give yourself access. Or if you don't want to change an existing domain configuration you can modify the security information in /etc via the "rdfile" and "wrfile" commands with cut-and-paste, i.e. add the SID for the windows user to the "Administrators" group in lclgroups.cfg and/or add a mapping for the Windows user to "root" in usermap.cfg. Another thing to check is the security style on the volume and the permissions on the /etc directory. One handy thing to do is make the /etc directory a qtree: Filer> qtree create etcnew Copy the contents of /etc to /etcnew Rename /etc to /etcold (from Windows) Rename /etcnew to /etc Then you can delete the /etcold directory or keep it there for a backup. The advantage of doing this is it allows you to separate out /etc for quota management purposes. Also, for a CIFS-only filer in a large domain environment where you want to restrict access to /etc to only specific filer admins you can set the security style on /etc to "unix" then create mappings to "root" in usermap.cfg for specific Windows admin accounts while locking the rest of the "domain admins" out of /etc. You can edit the UNIX permissions on the new /etc qtree using the free SecureShare Access". I've done this on a couple of CIFS-only sites where they had lots of domain admins but wanted only specifically trained filer admins to have access to /etc and it works a treat. Hope this helps.

Now I have no spare disks, and no room in any shelf to add disks. What do I do? I don't care about the information on the filer, I just want a root volume with 2 disks! I promise not to use all the disks on a single root volume again! I have a /etc directory on a NFS host. I don't have NFS license though so I can't copy files onto the filer via NFS, I have a CIFS license but for some reasons it says "access denied" when a CIFS client tries to access it. I have console access and telnet access, I'm so frustrated I took the filer home so I have physical access. I don't however have a support contract with netapp or an account on their site (pending their review of my application). I can't create any new volumes because all the disks are assigned to the root volume vol0.

Re: No spare disks for root.

Sorry about that last post being so full of typos - it was rushed as I'm at work and didn't want to waste much time on it. Adam is obviously correct that you'll need to restart from scratch now if you need to reconfigure your volume layout, which will require a backup and restore if there's any real data there. Just carefully consider whether you really need a second or third volume from the perspective of your data profile, not just because of the general recommendation for a separate root volume. Not only will you lose most of one disk's worth of space, you're wasting another drive for parity. As long as you have your backup and restore procedures nailed down so you don't risk overwriting your active /etc directory on a full volume restore it's really not worth it. You can always keep a copy of your /etc config files on other media for quick recovery just in case anyway. regards, Alan McLachlan Technical Consultant EBM-2 Project Queensland Health Ph. +61 7 31311618 Mobile 0428 655644 ***************************************************************** This email, including any attachments sent with it, is confidential and for the sole use of the intended recipient(s).

If I'm running CIFS on node 1 of a cluster, and I failover node 2 to node 1, will it disrupt the CIFS connections on node 1? Thanks, --Carl

Dump
by David McWilliams 29 Aug '07

29 Aug '07

I know this is a little 'non-NetApp' related, but please bear with me. I am in the process of trying to troubleshoot a Veritas NDMP backup problem on a filer. I have been asked to try using the dump command on the filer to see if I can backup successfully, thus taking NetBackup out of the picture. I would appear to have an NDMP three-way config, is using the dump command to check this config valid? -- Sláinte, David Get a safer, faster, better web browser @ http://www.mozilla.org/products/firefox/

clarion cx3-20 vs. netapp
by Willeke, Jochen 28 Aug '07

28 Aug '07

Hi toasters, has anyone a clue to which netapp modell the clarion cx3-20 can be compared?? I have read an older toasters-post where it is put in the ring with a fas270c. Is this really a good competitor? What do you think? Best Regards and thanks for your opinion Jochen

Cifs ACL reporting
by Jon Hill 26 Aug '07

26 Aug '07

We have a requirement to audit our cifs share security on a monthly basis. For my windows servers I use a vbscript leveraging WMI and the Win32_LogicalShareSecuritySetting. The filers don't respond to the WMI calls, so I thought I'd use plink to execute a cifs shares command. The problem is the formatting of the output of that command is atrocious - basically machine-unreadable. If I grep for "Domain Users," for example, I miss the shares that the group has access to. Plus the description field is usually separated from the path by a single space, which means there's no way for a script to tell where the path ends and the description begins (our paths include spaces). FilerView produces exactly the same output. I thought DFM might help but after reviewing the documentation it doesn't look like it applies. Has anyone come up with a good way to generate a useful (preferably tab-delimited) report on a filer's share permissions? If not I can ignore the description and path fields and kludge together the output I need. I was just hoping for a better way.

nfs not working until cifs terminate
by Willeke, Jochen 24 Aug '07

24 Aug '07

Hi toasters, today we had a strange issue on one of our R200 with 7.2.3 on it. The nstore was not serving nfs at all. There was no messages in the logs and the r200 was feeling quite well doing some cifs-ops and some other stuff. We really had no clue what was going on and support was confused, too. The only idea we had was to reboot the system (although ontap is no windows, ha :D), so we connected to the console and started to shut down cifs first in order to shut down the system and suprise suprise, as soon as cifs termination was finished NFS started to work again. We then started cifs too and now everything is fine again. I am really confused how this is related. Has anybody ever had this effect or an idea upon this? Best Regards and thanks in advance Jochen

Hi, in the syslog messages in FilerView is nothing about nfs. in the /etc/log/ems is a littlebit about nfs, but only lines like this: <LR d="20Aug2007 07:33:08" n="sodn02x" pn="sodn01x" t="1187587988" id="1184669953/106342" p="7" s="C=1U" o="ExportPool00" vf="erpvfiler"> <kern_syslog_msg_3 msg="Client erlm5p1x (xid 313175200), matches to erlm5p1x for misc access" vfilerName="erpvfiler"/> </LR> <LR d="20Aug2007 07:33:08" n="sodn02x" pn="sodn01x" t="1187587988" id="1184669953/106343" p="7" s="C=1U" o="ExportPool00" vf="erpvfiler"> <kern_syslog_msg_3 msg="Key erlm5p1x (xid 313175200), group ptdsiscon is not found in netgroup med for misc access" vfilerName="erpvfiler"/> </LR> <LR d="23Aug2007 17:14:28" n="sodn02x" pn="sodn01x" t="1187882068" id="1184669953/131313" p="7" s="C=1U" o="MNTPool08" vf=""> <kern_syslog_msg_3 msg="Client 146.254.168.188 (xid 102334387) in mount, does not have access rights to path /vol/vol0/delme_schaar" vfilerName=""/> </LR> but this is not really usefull vor debugging.
