If you turn it off, the owner should be able to chown a file that he owns. Hope this helps. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com

We are using a converter made by "Paralan" to connect an F630 (FW single ended) to a tape robot (FW diff.) The unit is active (has a power cord) but has worked so well we often forget it's there.

Graphing write volume?
by Brian Hostetter 08 Mar '00

08 Mar '00

I have installed filer-mrtg, which has almost all the information I need. The only thing I need now is to know how much bandwidth would be needed to mirror our 740 across a wan link. Since it should it is a mirror we should only need to know the amount of nfs writes. Also in filer-mrtg the Network K sent/recv seems really really low. It is showing us at 5.2KB/s? But when I graph something like 1:public@netapp I get about 30Mbps, Big difference. I tried to graph mib number ...789.1.3.1.3.1.1.34.1 but that gives me a 0. Ideas? --Brian

differential to single-ended
by George Kahler 08 Mar '00

08 Mar '00

Hi, I finally received a new F760 filer but failed to realize that the built-in tape interface will be differential. All of my current filers have dedicated ADIC 224 libraries with DLT7000 fast/wide tape drives. Q: I need to be able to connect the new F760 to the existing tape library. Does anyone know if there is a host adapter (fast/wide) that I can plug into the F760? If not, then my second thought was a passive differential to single-ended adapter. Does anyone have any experience with that? The backup software is NetBackup.

How do I determine the firmware level of the Q47 ? tmac(a)netapp.com on 03/08/2000 12:50:00 PM To: Fowle_Mark_D@cat.com@INTERNET cc: toasters@mathworks.com@INTERNET (bcc: Mark D. Fowle/0V/Caterpillar) Subject: Re: Tape Drives Retain Until: 04/07/2000 Retention Category: G90 - Information and Reports Yeah, I know a government customer who does. Word of caution: If the Q47 is somewhat dated, you should upgrade the firmware in the library. There is a bug in their firmware that prevents a filer running 5.3 and later from booting. The Q47 firmware in question is version 4.41. Moving to anything later than that will be fine, like 4.43 & 4.53. --tmac Mark D Fowle wrote: > I have a Breece Hill Q-47 tape library, and I was wondering if anyone has a > library similar to this attached to the netapps ? > > Mark Fowle > Caterpillar

It's kind of a fuzzy distinction, since you are trying to satisfy a diverse set of applications, but in general, EPERM ("Operation not permitted") is used to bounce attempts to do things that don't work because you're not the right UID/GID, whereas EACCESS ("Permission denied") is used when the object in question does not grant you access. In the case of NTFS qtrees, I think you could argue it either way, but to me it feels more like you're the "wrong user" than "this object denies access". We have plans to allow users from UNIX clients to manage NT ACLs on the filer, which would allow you to see what is going on in cases like this. In the meantime, now that the Samba team has published the necessary DCE/RPC info to do this*, there's nothing stopping some enterprising third party from providing such a command. Any takers? :-) Mark Muhlestein -- mmm(a)netapp.com *See Luke Leighton's book _DCE/RPC over SMB: Samba and Windows NT Domain Internals_ from Macmillan Technical Publishing. The Samba "rpcclient" utility gets you 95% of the way there. If anyone seriously wants to try this, let me know. -----Original Message----- From: Bruce Sterling Woodcock [mailto:sirbruce@ix.netcom.com] Sent: Wednesday, March 08, 2000 4:11 AM To: Bond, Andrew; bhaskar.g(a)philips.com; toasters(a)mathworks.com Subject: Re: Problem in ownerships ----- Original Message ----- From: Bond, Andrew <abond(a)netapp.com> To: <bhaskar.g(a)philips.com>; <toasters(a)mathworks.com> Sent: Wednesday, March 08, 2000 3:42 AM Subject: RE: Problem in ownerships > I'd take a quess that the file is on a qtree (or volume) with NTFS security. > This is expected behaviour in that situation. Good point. I would have expected a different error message (EACCES rather than EPERM), but it appears that chown(2) and utimes(2) may interpret those very strictly, and assume that EPERM must mean that you are not the owner if you're not root, rather than simply being denied write access. They don't seem to consider the possibility of being denied write access even when the times argument is non-NULL. Still, wouldn't it be more appropriate for the filer to return NFS[3]ERR_ACCES instead of NFS[3]ERR_PERM in those situations? Bruce

These libraries were a purchasing mistake. They aren't the most reliable on the market - that's putting it lightly. Graham
