tool to generate cifs I/O load
by Rhodes, Richard L. 30 Jan '15

30 Jan '15

I'm looking for a tool to generate a load onto a CIFS share from a Windows server. I see lots of comments out on the internet with folks using IOMETER to do this, but when I downloaded it I found that it doesn't support network shares. Any suggestions for a Windows tool to generate I/O onto a share? Thanks!

CDOT domain joining with a prestaged account?
by Basil 29 Jan '15

29 Jan '15

Installing my first CDOT machine, and when we got to the point of joining the first CIFS SVM to the domain, we hit a snag. It looks like ontap expects to be creating the machine account. In 7-mode, if it finds an account where it wanted to create one, it would ask if we wanted to reuse that. In CDOT, it just failed. I'm checking to make sure it's not something else like credentials or access, but has anyone else tried this? What should happen in CDOT when you join a domain where the computer account already exists? Basil

Everything in a qtree?
by Rhodes, Richard L. 22 Jan '15

22 Jan '15

Hi, Back about 7 years ago when we purchased our first NetApp systems we hired a NetApp consultant to help us set them up. One of the things he told me was to always put everything in a qtree. Whether it's a cifs shares, nfs export, or luns . . . put them in a qtree. I have followed that practice. I think part of this was that our NetApp systems are for a particular application and we use snapvault for some of the backups (luns and cifs shares). This is all on OnTap v8 in 7-mode. As I'm about to create some CIFS shares for other uses, I'm wondering if this is a good practice. The new shares would be volume snapmirror'ed to a DR site, but no snapvault. Any opinions are appreciated.

Failed disks...
by Camillo Gornati 20 Jan '15

20 Jan '15

Hello all… We have a FAS2040, with 2 shelves, which are not under support… One failed disk on shelf A, purchased disks, but i am afraid that will take about 1 week to receive them. What could happen if another disk fails (there is no more spares)? There is no DATA at all on SHELF B, should i get one disk from shelf B and put on A? If another disk goes bad, is it possible to make SHELF B takeover? Is it possible to destroy the aggr on shelf B and add it to shelf A so we would have 12 spares? What you guys would do ? Thanks in advance!

RHEL Kerberos root
by Edward Rolison 20 Jan '15

20 Jan '15

I'm hoping some of you fine folk can help my search for enlightenment. I'm working on getting Kerberos deployed across my environment. Our big stumbling point appears to be RHEL 5 and Kerberos root users. Specifically - RHEL5 hardcodes 'nfs' as a service principal to be used by 'root' for accessing an NFS mount. We've been looking at various different solutions, like creating an NFS user with uid 0, or (somehow) trying to map nfs <=> root on the filer. But was wondering - does anyone have a kerberized RHEL 5 environment? How are you handling root access? We've got RHEL 6 sorted, probably, because it looks like you can simply cut down your keytab to have 'just' root, which is then used for mounting/access etc.

cmod failover group
by Iluhes 14 Jan '15

14 Jan '15

Hi Folks,Do the failover group get generated by netapp intial install?Somehow I have a group call "0ba_fg" on the node that is called 06b. Looks like someone made a typo.But most importantly: It look like the policy for node mgmt IP only have 1 node in it, is that right? Should the second node be in the policy for mgmt1 for each node?the way it is setup now, will it failover?

Is it possible to copy a qtree to its own volume?
by Basil 13 Jan '15

13 Jan '15

I'm trying to take a qtree and move it into its own flexvol (7 mode). It has millions of small files, so robocopy or ndmpcopy are taking too long for the final pre-cutover sync of the migration. So far, the best option I can come up with is to use qtree snapmirror to copy it into a qtree in a new volume and share that qtree, however this isn't clean, and qtree snapmirror still has to span the filesystem. My other considered option was to use a volume snapmirror and then delete everything but the qtree that I need to keep on the destination volume once it's been split off, however this still leaves me with a cifs share pointing to a qtree instead of a volume. At least it would be a block copy instead of a filesystem copy, though. Anyone have any ideas? Basil

Lots of low water mark CPs on idle filer
by Edward Rolison 09 Jan '15

09 Jan '15

I've got a set of 4 filers, who have all - pretty much concurrently - decided to start racking up the 'low water mark' consistency points. E.g. wafl_susp -w is clocking up quite quickly, giving me as many as 10/sec. I think this may have caused my filers to get into a tizzy and crash, but I have two more that are still doing it. (I'm not 100% sure, because once they 'came up' the problem is gone ... for now). But anyway - these boxes have very little on them - they're not in service yet, so they only have a couple of vfilers and associated vol0s. So there is -literally- nothing happening, storage wise. The only activity is fairly regular ssh polling for performance stats/usual DFM activity. So can anyone give me a suggestion as to how to check why these might be running out of memory? I can stop the performance collection I guess, but that's been running fine for months. (And is also doing so on around another 40 filer heads, so I don't _think_ it's a problem!) They're 2240-4s, with a single shelf in a HA pair. I have 2 'pairs' (4 controllers) and the two that I've rebooted are fine again. The ones I'm looking at are dev, so I've held off doing so because I'd rather figure out what's going wrong instead.
