RE: Windows Shadow Copy Client & Snapshots
by Iain Barnetson 17 Mar '05

17 Mar '05

I don't know about that, I've only just become aware that it can be used and we're on version 7.0.0.1. And I know that I couldn't get it to work before switching on the snapshots using that command. Interestingly enough, and I've not got back to NetApp about this yet, I turned it off again - as I'm still not sure about providing this facility - and it still works. But it definately didn't before turning on that setting. Now that I've switched it off again I keep expecting the facility to disappear, I've been waiting to see what happens.

We are running 6.5.3P4 and have that option turned off and STILL users with Windows Shadow Copy Client can see the previous versions of their files and folders. We deliberately turned off showing the snapshots on CIFS because our users were confused about it (most of them have "show hidden files" option turned on). We installed the shadow copy client on their machines to help them do the restores themselves without the hassle of them "seeing" multiple copies of the same files when they do a search or browse through their shares and folders. The Shadow copy client was perfect for our needs - no ~snapshot folders visible, yet users can restore previous versions by themselves. NOTE: Even with show_snapshot set to off in 6.5.3, one can go into the snapshot folders by manually typing in the path, e.g: \\<filername>\<share_name>\<dir_name>\~snapshot\ either in the Run command box or widnows explorer. This would show the traditional snapshot folders. One more reason for us to stay away from 7.0.0.1 for now. Hope NetApp reverts the behaviour back to how it was in 6.5 and earlier versions. Would they consider this as a bug ? -G On Thu, 17 Mar 2005 10:22:49 -0000, Iain Barnetson <Iain.Barnetson(a)halliburton.com> wrote: > > > You may remember I emailed asking about using Windows Shadow Copy > Client as I couldn't see any snapshots. > My config is > Filer: Data OnTap 7.0.0.1 > Clients: Windows XP sp1 & sp2 > Snapshots were set to visible from the web gui > > Jourdan Bailey of NetApp found the solution that resolved the problem > and allowed us to use the Win Shadow Copy client: > options cifs.show_snapshot on > > > Regards, > > Iain Barnetson > IT Systems Administrator > UKN Infrastructure Operations

You may remember I emailed asking about using Windows Shadow Copy Client as I couldn't see any snapshots. My config is Filer: Data OnTap 7.0.0.1 Clients: Windows XP sp1 & sp2 Snapshots were set to visible from the web gui Jourdan Bailey of NetApp found the solution that resolved the problem and allowed us to use the Win Shadow Copy client: options cifs.show_snapshot on Regards, Iain Barnetson IT Systems Administrator UKN Infrastructure Operations

Although NetApp's OS looks nothing like BSD (it has no user space for instance, and a very different internal structure from any UNIX kernel), we certainly did use a good bit of code from the Net/2 and BSD-lite releases, back when that was being mostly funded by Berkeley and DARPA. As Luke says, we used the TCP/IP stack. Also the boot and locore code for both Intel and Alpha. And although we don't have a user space for commands to run in, we did take chunks of user space code in commands like "ping" and "ifconfig" and massage them into kernel code. I don't know the specifics, but I'd be surprised if we hadn't found more stuff to borrow over the years. I confess that we haven't made any dollar contributions, although if you look at the code contributions I think you'll find that Guy Harris (also of NetApp) and myself were both early contributors. For instance, I contributed cp(1). (When I was done, "cp -R" was a good bit faster than the AT&T version. Instead of doing the copy for a directory in a single pass, I scanned the directory twice, doing files on the first pass and directories on the second. This optimized for the fact that in FFS files in a directory tend to end up in the same cylindar group, so doing the files all together reduces disk seeks.) So at the time, we figured that we gave some code, and took some code -- call it even-Steven. :-) Not that I would object if we found a way to make a corporate contribution. We have made some source contributions to Linux, and I've personally made some contributions to Mozilla, so we are definitely fans of the open source movement.

In order for previous versions to work on WinXP SP1 and Win2K you have to install the Shadow Copy Client. http://www.microsoft.com/downloads/details.aspx?familyid=e382358f-33c3-4de7… WinXP SP2 does not require this installation as far as I know. //Johan Gislén > -----Original Message----- > From: owner-toasters(a)mathworks.com > [mailto:owner-toasters@mathworks.com] On Behalf Of Iain Barnetson > Sent: den 15 mars 2005 22:24 > To: toasters(a)mathworks.com > Subject: RE: Windows Shadow Copy client > > I've been trying to use Windows Shadow Copy client but when I > right click a file/folder although the previous version tab > is there no previous versions show. > I'm using WinXP sp1, Data OnTap 7, the shadown copies are set > to visible from the Web GUI. > > Do I have to enable something on the filer?

Donations thru guilt? Great tactic. Wasnt aware the license for BSD required tithing. I AM aware that the proper maintenance of a SCSI bus involves sacraficing goats however. What will Netapp now owe Crane for over a decade of trouble free flushing? What homage does Netapp pay BSD?

I've been trying to use Windows Shadow Copy client but when I right click a file/folder although the previous version tab is there no previous versions show. I'm using WinXP sp1, Data OnTap 7, the shadown copies are set to visible from the Web GUI. Do I have to enable something on the filer? I believe that's the case for Windows 2000 clients, but this is solely for WinXP sp1 & sp2 clients. Cheers Iain

RE: Quotas
by Iain Barnetson 15 Mar '05

15 Mar '05

Actually that sounds very similar, at first this affected only a few Qtrees & Home folders on the two volumes. Toward the end of yesterday afternoon I thought the filer had sorted itself out, this morning it started again around 09:30Hrs and was affecting pretty much all our qtreees & home folders. The problem became apparent yesterday around 13:00Hrs and dropped off around 16:30Hrs, starting again around 09:30hrs this morning but worse! So there may be some correlation between filer workload and this problem. What DFM was reporting and initially alerted one of the guys to there being a problem, was that about a dozen Qtrees were, according to DFM, set at 50Mb. The quotas file had them set to 31.5Gb. When a asked the filer for a quota report it itially told me that the quotas were set to 50Mb as well, after a quota off followed by a quota on I again queried the filer for a quota report, this time it reported the quotas correctly BUT still users couldn't write to their Qtrees or Home folders. I even forced the cluster partner to take over the disks and rebooted the filer having the problem but that dind't resolve it either.

Have checked the filer is reading the quotas file correctly by doing a rdfile /etc/quotas and comparing to the physical quotas file and it's exact. Have tried switching on and off the quotas, and also rebooting the filer (it works for MS boxes!) Have a ticket open with NetApp but so far no resolution.
