snapshots schedules and snapmirror for DR
by Rhodes, Richard L. 05 Feb '15

05 Feb '15

Since our filers are used for a document management system, backups (snapshots/snapmirror) are controlled by a host script which coordinates CIFS shares and Oracle DB backups, and DR transfers. Now, I've setup a general CIFS share (ie: a junk drawer) which uses "snap sched" for hourly/daily/weekly snapshots and snapmirror.conf to schedule snapmirror to a DR site. Q) When the snapmirror is broken and the DR copy of the share is in use, will the snap sched kick in and start working automatically, or does something need done for the DR site for the snap sched to start working?

The snapshot schedule is part of the volume configuration so it will start working automatically on the DR site if the snapmirror is broken off.

You’re right. CBC error. Computing Before Coffee. That said, is it generally kosher to mix speeds in any given shelf? RM From: Clark, André M.

meta: yahoo/hotmail/aol list users and DMARC
by Tom Yates 31 Jan '15

31 Jan '15

**PLEASE DO NOT REPLY TO THE LIST ON THIS MATTER.** Following a query by an aol user who kept getting unsubscribed, I did some digging, and the list has a problem with respect to mail from yahoo/ hotmail/aol, and a few other smaller domains. As far as I can tell, as summarised at http://postmaster-blog.aol.com/2014/04/22/aol-mail-updates-dmarc-policy-to-… , a few fairly large email providers have unilaterally implemented a policy called DMARC, and are now rejecting inbound emails that don't meet the policy requirements. In brief, the requirements are based on the content of the From: (the Header-From, rather than the Envelope-From) header line, and basically amount to "no mail may be sent with a From: line that matches our domain, from outside our domain). Until recently, this meant that whenever a list user from an afflicted domain sent mail to the list, noone inside an afflicted domain would receive it, and a bouncee would be generated for each such user. Recently, list traffic went up enough that sufficient bounces were generated to unsubscribe everyone on the list who was subscribed from an afflicted domain (47 users, the vast majority from yahoo and hotmail). They can resubscribe, and some have, but they will still not see emails from users in DMARC'ed domains, and if the list has another busy period, they'll all be unsubscribed-by-bounce again. As far as I can tell, the only remedy is to reconfig the list so that the From: address is set to a generic address, probably toasters(a)teaparty.net, rather than the actual sender (as it is now). This will mean that misconfigured autoresponders will send to everyone on the list, rather than to the sender as they do now. Before you ask, no, I am not willing to set it my own address, and sort through all the bounces manually. I've polled the other lists I'm on, and most (90%) of them seem to be ignoring the problem. I think DMARC is a rather foolish attempt to make the contents of the From: header reliable (at least as regards domain name), and am therefore inclined to ignore it, and say to yahoo/AOL/hotmail users that they need to subscribe from a provider with a bit more clue. But as usual I will be guided by you lot in this. If anyone feels strongly that the list should be reconfigured as described above, please let me know in the next week or two. If you have strong feelings the other way, it would be useful for me to know that also. And if anyone knows more about this than I do, and is aware of errors in the above, I'd value an off-list email even more. -- Tom Yates - http://www.teaparty.net

tool to generate cifs I/O load
by Rhodes, Richard L. 30 Jan '15

30 Jan '15

I'm looking for a tool to generate a load onto a CIFS share from a Windows server. I see lots of comments out on the internet with folks using IOMETER to do this, but when I downloaded it I found that it doesn't support network shares. Any suggestions for a Windows tool to generate I/O onto a share? Thanks!

CDOT domain joining with a prestaged account?
by Basil 29 Jan '15

29 Jan '15

Installing my first CDOT machine, and when we got to the point of joining the first CIFS SVM to the domain, we hit a snag. It looks like ontap expects to be creating the machine account. In 7-mode, if it finds an account where it wanted to create one, it would ask if we wanted to reuse that. In CDOT, it just failed. I'm checking to make sure it's not something else like credentials or access, but has anyone else tried this? What should happen in CDOT when you join a domain where the computer account already exists? Basil

Everything in a qtree?
by Rhodes, Richard L. 22 Jan '15

22 Jan '15

Hi, Back about 7 years ago when we purchased our first NetApp systems we hired a NetApp consultant to help us set them up. One of the things he told me was to always put everything in a qtree. Whether it's a cifs shares, nfs export, or luns . . . put them in a qtree. I have followed that practice. I think part of this was that our NetApp systems are for a particular application and we use snapvault for some of the backups (luns and cifs shares). This is all on OnTap v8 in 7-mode. As I'm about to create some CIFS shares for other uses, I'm wondering if this is a good practice. The new shares would be volume snapmirror'ed to a DR site, but no snapvault. Any opinions are appreciated.
