RE: CIFS & Cluster Failover

Nope.

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

AW: nfs logging / debugging

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.

nfs logging / debugging
by Zeitschel, Philipp 24 Aug '07

Hi, I'm new to this list, and my english is not very well... i've got some nfs problems, so i wan't to read some log's. With the option nfs.mountd.trace on the filer logs some stuff to /etc/log/ems, is that right? the ems log, looks like some pseudo xml, is there a special tool to analyze the file? are there other possibilitys to debug nfs on the filer? NetApp Release 7.2.3 greeting Philipp

Re: copying qtree

Meanwhile i read the documents and it looks like ndmpcopy is the best option as i have limited downtime (3hrs total). I will also try out VFM and robocopy on the simulator. I would like to thank each one of you for taking time to answer the queries. We have ordered few more Filers and i hope to improve my knowledge of the netapp systems by then. If I get stuck somewhere, I now know whom to ask... :) Thank you very much.

copying qtree
by Lohit 22 Aug '07

22 Aug '07

Hello experts, I am very new to the netapp world. Sorry if this has been answered already or if it sounds stupid.I have the following situation, What we have is a FAS940 with DS14MK2 shelves(3nos). There is a qtree "proj-CFD" which is 200GB in size and the containing volume is 500GB. The volume is 90% full. I have been asked to increase the space for the qtree to 400GB. Previous admin created the aggregate(Aggr1) with a raidsize of 8 and there are two raidgroups with 8disks in each raidgroup. I have three spares and adding these to the current aggregate would create another raidgroup of 3 disks and i will be left with 1 usable disk (we have raid_dp) and also i will have no spares left. But fortunately there is another aggregate(Aggr2) with a raidsize of 16 and there are 14 disks in that aggregate now. Now my question is, how can move the "proj-CFD" qtree to a volume in Aggr2 with minimum downtime and keeping all the ACLs intact(It is ntfs only). Thanks -- With warm regards Lohit
