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

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.

Cyber Liability and Data Breach insurance Coverage
by Mike Linett 02 Jan '15

02 Jan '15

Hi: We have spoken to our business insurance brokers about cyber liability and data breach insurance and they assure us that our internal storage is covered, but they will not cover data stored in a 'cloud provider' against cyber liability and Data Breach. Has anyone found a commercial insurance package that provides cyber liability and data breach coverage for data located on a commercial service like Salesforce.com?
