RE: Snapvault question
by Glenn Walker 18 Jan '07

18 Jan '07

To clarify this further: I _believe_ you can make use of VSM, then implement QSM\SV, but you would end up losing the existing snapvault relationships. I'm not so sure the LREP is much of an improvement on this. I hope I'm wrong.

Oracle Replication & Snapshot-space Queries
by Raj Patel 18 Jan '07

18 Jan '07

Hi, Couple of quick queries - 1. In terms of Oracle data replication - is it worth using low level data replication to another SAN (eg using NetApps tools) or do it via Oracle itself ? Which is 'safer' / 'faster' ? Whats the bandwidth requirement comparison for SAN replication vs database replication ? 2. What sort of space utilisation do people 'allocate' for their snapshot cycle ? Vendors quote storage space and snapshot functionality but seem to gloss over the fact that snapshots eat into the SAN's available space. Thanks in advance, Raj.

DR suggestions for CIFS
by Ammar Zolkipli 17 Jan '07

17 Jan '07

Guys, I'd require some input for a project I'm involved in. I have two sets of 3050 clusters in two sites. The primary site is serving CIFS data to home and project directories. The secondary site is just the snapvault destination, and tape backup source. Now, we're planning to do a DR implementation for this setup. From what I can recall, there are a few things that you need to do to make it work: 1. have snapmirror and snapvault (SM-SV combo) license at the secondary site. I can turn a snapvaulted volume snapshot into a RW volume. Is that correct? 2. I copy the cifs shares config file from the primary filer, edit it a little bit, and paste it into the secondary filer 3. I need refresh my DNS server to point to the secondary filer IP address using the primary filer hostname. Anything else that I need to do? I heard something about changing netbios names as well, but I don't really understand windows enough to know what that will do to help with the DR. Oh, and also, the MS active directory domain are running on win2k3 servers. I'm assuming that different AD versions will significantly in make DR implementations different? Thanks for any feedback

RE: wafliron output -- is wafl OK?

So far as I know, it's still logged to /etc/messages with output. It will show any corrections and completion status. It does not prompt for committal of changes, unlike wack/wafl_check.

Why did you run wafl_iron in the first place? It will log corrections in the messages log, if I remember correctly. Maybe there is a new seperate log under etc/log these days.

Re: User defined Notifications

If you do this, I assume you had to set some thresholds somewhere on the filer right? I didn't realize that sending those thresholds would do anything other than send snmp traps. I'll consult the docs, but do you have a quick syntax on how you set those thresholds (preferable from the command line). ----- Original Message ---- From: Glenn Marsh <glennm(a)latticesemi.com> To: toasters(a)mathworks.com Sent: Monday, January 15, 2007 1:27:08 PM Subject: Re: User defined Notifications I have been using SWatch (System Watch) for some time now for this purpose with great success. http://sourceforge.net/projects/swatch/ It is Perl based and fairly easy to configure. ************************************************************************ Glenn Marsh Lattice Semiconductor Corporation Senior Unix Systems Administrator 5555 NE Moore Court CAD Engineering Hillsboro, Oregon 97124 glenn.marsh(a)latticesemi.com 503-268-8000 503-268-8136 phone - 503-268-8459 fax ************************************************************************ ____________________________________________________________________________________ Looking for earth-friendly autos?

NetApp equivalent of all_squash,anonuid=100,anongid=100
by NetApp 15 Jan '07

15 Jan '07

I'm trying to set up an NFS path where all clients get squashed to a single UID The normal export doesn't work, as my NFS clients are Linux 2.6 with real uid/gids sent /vol/vol1 -sec=sys,rw,anon=100 In this case, only ROOT client access get squashed to uid 100. Instead, here's what I tried: /vol/vol1 -sec=none,rw,anon=100 Unfortunately, my Redhat Linux client (2.6.9-42.ELsmp) refuses to mount Mounting NFS filesystems: mount: 192.168.1.10:/vol/vol1 failed, security flavor not supported Packet traces show the Linux system sends the MNT request with Flavor AUTH_UNIX, and the NetApp replies OK-Flavor:AUTH_NULL along with the appropriate supplemental fsid file handles. Only, Linux is 'smart' and refuses. I also don't have any server side control over GID either.
