RE: Legato and NDMP
by Hill, Aaron 09 Apr '03

We use legato to backup over NFS mounts and it works perfectly. Note: must be hard mounts, not automounter. In fact, we have just installed and R100 and R150 to do staging via legato. The idea being we suck the data on to the R100 quickly and then move it onto tape at our leisure. Snapvault is going to fit in there for fast retrieval. The bonus is that it can be used just like normal Legato restores using the Disk Backup/NetApp Nearstore module for Legato.

I set my schedules to do levels 1,2,3,4. etc in the days after a full (level 0) which works fine for me. You can backup over the NFS mounts, I know some people do that. Matt

quotas and unix automount
by Charles Bartels 08 Apr '03

08 Apr '03

Hi, Is it possible, with individual user quotas and automount, to have mount points reflect the user's quota? For example: Currently df shows my home directory like this: Filesystem kbytes used avail capacity Mounted on pluto:/vol/vol0/home/cbartels 15728640 9979060 5749570 64% /home/cbartels But my quota is this: pluto>quota report /vol/vol0/home/cbartels K-Bytes Files Type ID Volume Tree Used Limit Used Limit Quota Specifier ----- -------- -------- -------- -------- -------- ------- ------- --------------- user cbartels vol0 home 336836 5242880 3545 - cbartels tree 6 vol0 home 9979304 15728640 390987 - /vol/vol0/home It would be great if /home/cbartels looked like a 5GB (my quota) partition instead of the ~16GB which is the size of the qtree quota. -Charles Bartels

Peoplesoft cache
by Bui, Marcus 08 Apr '03

08 Apr '03

Hello Toasters, I ran into a weird problem with Peoplesoft (PS). The client run PS from the Citrix Metaframe 1.8 server with the PS database on the Unix Server. The client cache folder resides on F760c (ONTAP 6.3.1R1, Gig NIC). The cache folder has the client's configuration settings when the app is started. With this setup, it takes about 5minutes to load the app and 100MB of traffic exchange between the Filer and the Citrix server. Even though the cache folder only has about 1.5MB of files. I'm not an expert in decoding network traces but it show a lot retransmission packets size of 1.4MB with no data. But when I moved the cache folder to another NT server or Filer F820 (ONTAP 6.3.1R1, Gig NIC), the app loads in 10secs. Any ideas? thanks, Marcus Bui

Re: converting a directory to a qtree (fwd)
by Haynes, Tom 08 Apr '03

08 Apr '03

I was told this never made it to the list. If it is the case that it made the list, but was blocked at NetApp, please excuse the noise. Most move algorithms are: move(old, new) if (!rename(old, new)) { copy(old, new) if (is_dir(old)) { foreach entry in old { move(old/entry, new/entry) } delete(old) } In pre-6.4 systems, we always failed a rename() for directories and files between qtrees. In 6.4 systems, we allow renames() for files across qtrees, but not directories across qtrees. A rename() results in the inode and none of the data nodes, being modified. Thus a 10G file gets moved as fast or as slow as a 1k file. Allowing the rename() of the dir adds too much complexity in that we would have to handle atomicity, recovery, users modifying subdirs, multiple hard links inside the directory (detecting whether it stayed within the tree or not), and so on. Handling just the files reduces the majority of the IO with a resulting savings in time and space. I.e., the inode is all that changed, so that the snapshot ends up with about 4 dirty blocks and not effectively 2 per data block in the file. BTW: The FSF implementation of mv, as seen in most Linux distros, etc, has an optimization which states that if a directory can not be renamed, then its children can also not be renamed. FSF have removed that in coreutils-4.5.2 such that mv will take advantage of this new feature in OnTap 6.4. --------------------------------------------- Chris Thompson asked: > What happens if the file being rename()'d has multiple hard links? Wouldn't > this result in the inode being linked into more than one qtree? I replied: We don't allow the rename, which forces a copy. This in turn reduces the hard link count. ----- Forwarded message from Steve Losen ----- >From owner-dl-toasters(a)netapp.com Fri Mar 14 06:18:05 2003 X-Authentication-Warning: fred.mathworks.com: majordom set sender to owner-toasters(a)mathworks.com using -f Message-Id: <200303141353.h2EDrhB04815(a)sasha.acc.Virginia.EDU> X-Mailer: exmh version 2.4 06/23/2000 with nmh-1.0.4 To: "Toasters" <toasters(a)mathworks.com> Subject: Re: converting a directory to a qtree In-Reply-To: Your message of "Fri, 14 Mar 2003 09:05:46 GMT." <003101c2ea09$1c676aa0$43c1869f@E689> Date: Fri, 14 Mar 2003 08:53:43 -0500 From: Steve Losen <scl(a)sasha.acc.virginia.edu> Sender: owner-dl-toasters(a)netapp.com Precedence: bulk > Hi, > > Has anyone any experience of converting a directory to a qtree (we want to > make use of the qtree to qtree snapmirror features in DOT 6.2 and greater) > > There's a doc on NOW which gives two ways either do a copy, which requires > enough free space (which we don't have) or to use the built in ndmpcopy > feature of DOT. > > There's also the possibility of doing a 'mv' on each file, although I'd be a > bit concerned that this might leave the filesystem in a less than optiomal > state on the filer. > > I'd be interested in hearing from anyone who has done this, especially about > throughput (The directories we need to convert have approx 150G of mail in > them, so lots of small files, on a 840C) > GB > > ---- > Garrett Burke, > Service Implementation & Support Manager, > Eircomnet. > http://www.eircom.net As far as I know, there is no way to move a file across a qtree boundary other than to copy the file and delete the original. Even if you use the unix "mv" command, when crossing a qtree boundary mv must copy and delete. Since you have limited free space, you may need to copy and delete each mailbox individually. If you are using snapshots, this will obviously gobble up most if not all of your snapshot reserve, so you may need to delete all your snapshots beforehand.

Legato and NDMP
by Gavin Kelman 08 Apr '03

08 Apr '03

We've just received a nice new F825, which we're trying to integrate into our exsiting Legato Networker backup system. I've been speaking to our Legato support, but they're not getting very far, and each day that passes is another day for us without backups. We have a Quantum ATL1500 jukebox directly attached (Robot controller and one drive) to a Sun box, which is a Legato storage node. The 2nd SCSI drive is connected to the back of our F825, which picks it up fine, and is configured as an NDMP device in Networker. Now, the problem is, Networker complains that it can't establish an NDMP connection to the F825, even tho NDMP is enabled on the F825, and I've double-checked the username is root and the password is correct. Attempting to do an inventory in nwadmin fails on either device in the jukebox. Also, NDMP doesn't do incrementals the normal way, so I was thinking of just backing up the F825 over the NFS mounts, but I hear that's not a good idea with Legato. We're running DOT 6.3.1r1 and Legato Networker 6.1.3. Anyone have any suggestions, apart from "stop using Legato"?

RE: Security on Win2k

Thanks to all who responded. Pls check this fix in ONTAP 6.4.R1: * 91117 Incorrect permission check when creating a file from CIFS Regards, Bill -----Original Message----- From: Mike Sphar [mailto:mike.sphar@Remedy.COM] Sent: Thursday, March 27, 2003 8:22 PM To: toasters(a)mathworks.com Subject: RE: Security on Win2k This doesn't sound correct to me. Have you actually tested it? In windows network permissions, share permissions are applied first, then individual file or directory ACLs are applied, and the most restrictive permissions always apply. So if a share is read-only to a user, then even if all the files in that share are writeable by everyone, then that user should not be able to update those files or create any new files or directories in that share. I would be very surprised to find that Netapp was not emulating the standard windows file server behavior in this case. -- Mike Sphar - Sr Systems Administrator - Remedy, a BMC Software Company -----Original Message----- From: Bill Bello [mailto:Bill.Bello@hds.com] Sent: Thursday, March 27, 2003 6:46 PM To: toasters(a)mathworks.com Subject: Security on Win2k All, A question has come up in our lab on the subject. If 'read only' is set on the filer for a CIFS share, a user can still have full rights to that share IF security is NOT set in Win2k as well. Has anyone figured a way to make the share secure from the filer only? Thanks in advance.

quota question
by Charles Bartels 02 Apr '03

02 Apr '03

Hi Folks, I have yet another quota question. Do I need explicit extries in the quotas file for all PC users or can I use a wildcard? The reason I'm asking is that all the PC users get mapped to "pcuser" which is the setting in wafl.default_unix_user. So the result is that *all* the users get counted in the same quota. Thanks. -Charles Bartels
