RE: Requests on Slashdot for donations for OpenBSD.

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? It could be running Linux. -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com]On Behalf Of Maren S.

Anyone who uses a NetApp knows immediately that the OnTap OS is BSD, always has been BSD. Considering the Billions (yes, Billions) of dollars in revenue NetApp has derived from the BSDs, I am appalled at the company's lack of contribution back to the BSD community!

RE: Windows Shadow Copy client
by Iain Barnetson 15 Mar '05

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

When you make a change to a file then try using the previous versions tab, does the previous version appear?

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.

If I run quota resize again, it complains about the default user entry. Quotas remain confused like this until I perform a full quota off/on, then quotas seem to operate perfectly fine for me.

Well, it's alarmingly reminiscent of two recent toasters threads "unix quota and df" (Charles Bartels) "df size reporting differences in ONTAP 7.0" (Adam McDougall) except that they didn't actually report "disk full" conditions. I think the chances of us going to ONTAP 7.x at Easter are now almost indistinguishable from zero! Many thanks to those of you who jumped in the deep end, and let us know where to send the wreath ... :-) It's a pity that no-one from NetApp has contributed to any of these threads. Surely someone there at least knows what they were _trying_ to do with (NFSPROC_STATFS, NFSPROC3_FSSTAT, etc.) results? -- Chris Thompson Email: cet1(a)cam.ac.uk

RE: single vs. multiple nfs mounts
by Jeff Mohler 15 Mar '05

Well..back in the bad old days (1998ish) when I was running God's own public Usenet service with cyclone/typhoon products, I learned that parellelizing NFS mounts was a -huge- performance benefit in the Solaris of the day until you reached the limits of the machine itself. The filer didnt care, the client OS sure did. I can only assume it's the same today. -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com]On Behalf Of Steve Losen Sent: Tuesday, March 15, 2005 3:18 PM To: George Kahler Cc: toasters(a)mathworks.com Subject: Re: single vs. multiple nfs mounts > >I'm a bit worried over the resultant nfs performance all going though > >this single mount point.

However, if it makes sense to use different NFS options for different applications, then I believe you can still do it. Just mount the same netapp volume on different mount points with different sets of NFS options, and on the NFS client have each app use the appropriate mount point for the NFS options it needs. mount -o rw,hard,opt2,opt3 toaster:/vol/big /mnt1 mount -o rw,hard,opt4,opt5 toaster:/vol/big /mnt2 ...

None

Hi - I have all our Oracle9i databases defined as individual qtrees spread over two filers. Some time ago the decision was to split an individual database into 3 separate components (qtrees), one for the data (tables) the other two qtrees for duplex logs, one on each filer head. A Sun Solaris 8 dataserver that runs 6 Oracle databases then has 18 nfs mounts. On the recommendation of NetApp the qtrees are mounted with these options: rw,hard,intr,bg,proto=tcp,llock The DBAs now would like to have this rearranged so that there is a single qtree per dataserver host (think of this as one large blob of space) with ALL of the databases that this server will run as a sub-directory of this qtree. I'm a bit worried over the resultant nfs performance all going though this single mount point. Can someone comment on the issues of multiple nfs mounts vs. a single mount ? What about locking ? Thanks, George

RE: unix quota and df

I believe this has shown up as a bug on the NOW site. I would check. I seem to remember seeing something like this in 7.0+ bug list. Derek -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Charles Bartels Sent: Monday, March 14, 2005 1:48 PM To: toasters(a)mathworks.com Subject: unix quota and df Hi, I have a filer running ONTAP 7.0 connecting to a Solaris box with automounted home directories, and I'm getting different results depending on whether I have a quota in a qtree vs. a volume. If anyone can shed some light on this "problem" I would appreciate it. Thanks. -C. In the examples below, there is 35GB qtree ("home") under vol0 and a 35GB flexible volume ("home"). Both have default user quotas of 5GB. If a user's home directory is in a qtree and they do "df" on the unix box, their "partition" shows up sized to their quota. This is good; although this is *not* the way things worked pre-ONTAP 7.0 Ex. User1@unixbox> df -kh . Filesystem Size Used Available Use% Mounted on filer:/vol/vol0/home/user1 5.0G 2.0G 3.0G 40% /home/user1 If a user's home directory is in a volume, their "partition" shows up sized to the size of the volume. They need to run "quota -v" on the client to get their quota. Ex. User2@unixbox> df -kh . Filesystem Size Used Available Use% Mounted on filer:/vol/home/user2 32G 11G 21G 35% /home/user2 User2@unixbox> quota -v Disk quotas for user2 (uid 1001): Filesystem usage quota limit timeleft files quota limit timeleft /home/user2 1914808 5242880 5242880 2172 -1 -1
