Weird CIFS problem
by David McWilliams 01 Feb '08

01 Feb '08

I'm domain admin, and I'm accessing a share on my filer \\filer1\tdrive<file://filer1/tdrive>(/vol/vol0/tdrive). It is a seperate qtree, the only perms on the share are everyone/ full control. I even added a domain/administrator full control entry. I can see the top level of sub-dirs, bt I cannot go any deeper. Does this make sense, or am I missing something? -- Sláinte, David Get a safer, faster, better web browser @ http://www.mozilla.org/products/firefox/

ToE and NFS in VMware
by Page, Jeremy 30 Jan '08

30 Jan '08

On page 20 of Network Appliance and VMware ESX Server 3.0 Storage Best Practices the authors say "With the release of VMware ESX 3.0.1 Support for TOE enabled NICs has been added", can someone tell me where I can find a list of TOE enabled NICs for 3.5? Everything I have read says that TOE is only supported for iSCSI, not NFS. I am getting ready to move a mid to large sized ESX environment from FC to NFS (probably with x3850's) and I want to make certain I get the right NICs. If I can use TOE cards for NFS then that's a no brainer, but I want to make certain there will be a benefit. If not does anyone have any recommendations? I want to make certain they support TSO and hopefully IOAT (at least I'd like to experiment with it), even if they are just regular NICs This message (including any attachments) contains confidential and/or proprietary information intended only for the addressee.

NetApp & Leopard
by Carl Howell 30 Jan '08

30 Jan '08

I've stumbled across a problem we're having accessing filer hosted CIFS shares from Mac OS X Leopard 10.5.1. The Leopard boxes I've tried this on are all bound to our Win2k3 Active Directory. If you log into Leopard with your domain credentials and try to access a share on a filer(this happens on all of our filers and all are at 7.x and above), you will be prompted for your password. If you try to access the same CIFS share hosted on a Win2k3 box, you will get right in. Has anyone else seen this? Thanks, --Carl

Usermapping from Linux User to WIndows
by Willeke, Jochen 30 Jan '08

30 Jan '08

Hi Toasters, i have a question regarding usermapping from linux users (local /etc/passwd) to windows users. Let me explain my problem with a short example: SystemA, alex (UID 600) SystemB, alex (UID 700) --------- usermap.cfg DOMAIN\user.test <= SystemA:alex DOMAIN\user.test <= SystemB:alex --------- /etc/passwd on the filer alex::600:600:user:/home/user: --------- When i mount a qtree (NTFS-Sec-Style and "DOMAIN\user.test" has access) on SystemA everything works, but when i want to use it from SystemB it won't work due to the different UID. Does anyone know if there is a way to get this running, or are the only solutions to have the same UID's in local /etc/passwd on the hosts or to have a directory service like NIS for user-management??

Recommended iSCSI timeout
by Robert Lazzurs 29 Jan '08

29 Jan '08

Hello all, I have been searching for a while on the NOW site and the only reference I can find about what the timeout settings for iSCSI should be are in "iSCSI SUSE(R) Linux(R) Host Utilities 3.1 for Native OS Setup Guide". In that document it says the configuration value node.session.timeo.replacement_timeout should be set to 5 however the default it 120. Now if anything I expected for head failover to work it would have to be higher? Does anyone have any experience with iSCSI head failover in Linux who can comment on what this value in the iscsid.conf should be? Thanks in advance.

Thin provisioning LUNs, A-SIS, and notifications
by Daniel Keisling 27 Jan '08

27 Jan '08

Hello, I am starting to thin provision LUNs (lun set reservation disable) in order to start using A-SIS on some large (1TB) volumes. Before I turn A-SIS on, I started testing these LUNs and do see the space on the filer grow accordingly with writes on the host. However, the space never seems to go down when I delete files on the host: rtpstore2b> df /vol/iscsi Filesystem kbytes used avail capacity Mounted on /vol/iscsi/ 10485760 9974748 511012 95% /vol/iscsi/ /vol/iscsi/.snapshot 0 0 0 ---% /vol/iscsi/.snapshot [root@vrhel5 /]# df /mnt/iscsi Filesystem 1K-blocks Used Available Use% Mounted on /dev/sde1 10321192 7804844 1992064 80% /mnt/iscsi I see that when I begin writing again, the filer space won't start increasing until there is an increase in space above what the filter already thinks. Is this behavior normal? When I turn SIS on, will the filer LUN size reduce as blocks are deduplicated so that I can then reduce the volume? Lastly, I will definitely need to know when my volumes autosize so I can focus my attention on not having the aggregate fill up. It would be wonderful if I could set up an SNMP trap to send to Nagios for notification. Before I dig into the MIBs and create the custom trap (if I even can), has anyone done anything similar they could share?

ssh public key authentication (NetApp Release 7.2.3)
by Karl Amrhein 25 Jan '08

25 Jan '08

NetApp Release 7.2.3: Thu Jul 5 10:06:16 PDT 2007 How do I get ssh public key authentication working? I tried putting ssh V1 and V2 public keys in /etc/sshd/authorized_keys /etc/sshd/authorized_keys2 /etc/sshd/root/.ssh/authorized_keys /etc/sshd/root/.ssh/authorized_keys2 But none of that worked. Is there some documentation about how to get ssh key (non-password) authentication working? Thanks in advance, Karl

Netapp and VMware ESX 3.5
by Davies,Matt 25 Jan '08

25 Jan '08

Hello all, Having decided to upgrade our VMware ESX servers to 3.5 from 3.0.2, we have come across a strange problem. On each ESX server we have 3 VSwitches, 2 of them each contain a service console port and VMkernel port. One of Vswitches we have been using for Iscsi in ESX 3.0.2 without any problems. (The first VMkernel port is enabled for Vmotion and is routable) Once we upgraded to 3.5 we have noticed that the filer now shows 2 sessions from the esx host, one from each of the VMkernel ports, however one of the paths is routed and one of the paths is switched. On the ESX host we see each LUN twice, with different paths but with the same canonical path. Does anyone know how to restrict what targets are being sent by the filer based on the interface ? We cannot disable Iscsi on any of the interfaces on the filer. Or does anyone have any other bright ideas ?

Cleaning up Messy SW iSCSI connections
by Hadrian Baron 25 Jan '08

25 Jan '08

Hello Toasters, We have Snapdrive + MS iSCSI on a few boxes. I've noticed that once in awhile the iSCSI connection will become unavailable. If you browse the iSCSI front-end in Snapdrive, it will show unavailable where it would show the IP addresses for target & portal. If you browse the iSCSI control panel, it shows a target that is "reconnecting", but you cannot disconnect it to properly re-establish the connection. Does anyone have a way to properly clean up these connections? Typically disabling iSCSI / Snapdrive services, bouncing the box, and turning them up will let me re-establish, but this is painful. If anyone is wondering, it's Snapdrive 4.2.1 + MS iSCSI 2.05. Thanks all, - Hadrian
