Vsphere 5.5u1 vs NFS
by Andrew Laurence 24 Apr '14

24 Apr '14

Word is going around that vSphere 5.5u1 causes lots of NFS disconnects. Has anyone here seen this? http://datacenterdude.com/vmware/nfs-disconnects-vmware-vsphere/ -Andrew -- Andrew Laurence Office of Information Technology atlauren(a)uci.edu University of California, Irvine

OCB setup and filer addition
by Ehrenwald, Ian 24 Apr '14

24 Apr '14

Hello I've downloaded a demo of OCB 4.1.1.2R1 virtual appliance. When attempting to add a/any filer to OCB using either predefined credentials or new ones, the response OCB comes back with is "Unauthorized". When connecting to the filer via HTTPS in a browser I get "Error 505 - HTTPS not supported". I believe my httpd options look fine: netapp01> options http httpd.access legacy httpd.admin.access legacy httpd.admin.enable on httpd.admin.hostsequiv.enable off httpd.admin.max_connections 512 httpd.admin.ssl.enable on httpd.admin.top-page.authentication on httpd.autoindex.enable on httpd.bypass_traverse_checking off httpd.enable on httpd.ipv6.enable off httpd.log.format common (value might be overwritten in takeover) httpd.method.trace.enable off httpd.rootdir /vol/vol0/home/http httpd.timeout 300 (value might be overwritten in takeover) httpd.timewait.enable off (value might be overwritten in takeover) netapp01> netapp01> options ssl ssl.enable on ssl.v2.enable on (same value required in local+partner) ssl.v3.enable on (same value required in local+partner) netapp01> netapp01> secureadmin status ssh2 - active ssh1 - inactive ssl - active netapp01> I've read that I could possible do 'secureadmin setup -f ssl' to regenerate the SSL certificates but I'm not sure I want to do that yet, as other things I use may depend on the installed certificate. Using SSH to get to the filer with the same credentials I'm telling OCB to use does work correctly. Any hints?

ONTAP 8.1.4P2
by Philbert Rupkins 24 Apr '14

24 Apr '14

Hi Toasters, Has anybody upgraded to ONTAP 8.1.4P2 yet? We were planning an upgrade to 8.1.4P1 and just noticed the availability of P2. It looks like 8.1.4P2 was released on 4/21 (Monday of this week). If you have upgraded to 8.1.4P2, why did you upgrade so quickly and how has your experience been thus far? We generally like to wait a while before upgrading to a recent patch level but some of the issues fixed with 8.1.4P2 seem compelling enough to take the plunge. Hope all is well with everybody! -Phil

Determining what's contributing to fast aggregate growth
by Fletcher Cocquyt 16 Apr '14

16 Apr '14

Hi all, In the last 36 hours or so we have a 19Tb aggregate that is growing above 18Tb used. Usually the aggregate used level only grows if we grow its volumes. This is different - I was forced to delete snapshots and shrink volumes to get it back under 90%. And in the last 3 hours its back above 91% - used level is climbing 5-10g/minute I so far can not see where the growth is coming from, Aggr snapshot is OFF Ontap 8.1.2 na02> aggr status Aggr State Status Options aggr0 online raid_dp, aggr root, nosnap=on, raidsize=19 64-bit thanks for any tips!

admin access to ntfs permissions
by scl＠virginia.edu 11 Apr '14

11 Apr '14

Hi folks, I have run into some ntfs permission problems on a filer running 8.0.1 7-Mode. I am not a Windows domain admin, just the filer admin. I thought that I could map the share using the filer Administrator account like this: share: \\filer.virginia.edu\sharename user: filer.virginia.edu\Administrator I can login just fine, but this account apparently has no special admin privileges. I get permission denied when I try to access folders whose ntfs permissions I suspect are wrong. I also tried filer.virginia.edu\root but login fails. So does this mean that only Windows Domain admins can repair these permissions? And what about this filer option: wafl.nt_admin_priv_map_to_root Must this be "on" ? What do you do if someone revokes all access to a ntfs style folder? Is there any way for a filer admin who is not a Windows domain admin to get unrestricted access to all ntfs security style objects? Can a Windows domain admin even do this? I searched Netapp support but it just says to login as a user "with enough privilege" to change the permissions. Thanks for any help. We almost always use Unix security style.

nfs.authsys.extended_groups_ns.enable?
by Rue, Randy 11 Apr '14

11 Apr '14

Hello All, Trying to work around the 16 group limitation of NFS v3 on our 8.1 vfiler and finding references to a "hidden" option "nfs.authsys.extended_groups_ns.enable" that will effectively disable group lookups via auth_sys/RPC and instead look to the filer's AD authentication for a user's group memberships. This is similar in spirit to Isilon's "mapuid" feature and "regular" NFS's -manage-gid switch. But I've tried in regular mode, priv set advanced and priv set diag, and I always get "No such option nfs.authsys.extended_groups_ns.enable" if I try to view or change the option. Am I missing some step to make this hidden double-secret-probationary option available? Randy

snapmirror destination volume is not growing after source
by Iluhes 10 Apr '14

10 Apr '14

Folks, Please help I have snapmirror setup between 2 qtrees. netapp1:/vol/vol1/q1 --> netapp2/vol/vol1/q1 I was under impression that in 8.2 you can add space to source volume and destination will grow. When I add space or change maxfile on source, the destination remains the same Is my issue due to having just qtree snapmirror? Or I am missing something? fs_size_fixed=off

CPU usage and HA
by Martin 08 Apr '14

08 Apr '14

I know that if a Filer is not busy serving data it will run background task at a higher priority that will use the spare CPU while the Filer is not under load. In an active/active config the Filer CPU shouldn't be over 50% on each controller as above this the Filer is not longer HA. My question is if a Filer is showing low latency and isn't busy but its CPU is at 50% on each controller is this an issue? I'm not clear if you have two controllers showing 40/50% CPU due to background tasks that isn't busy whether it will still be HA if one controller were to fail? My thinking is those background tasks will just run at a lower level (some may not run in failover state??) -- View this message in context: http://network-appliance-toasters.10978.n7.nabble.com/CPU-usage-and-HA-tp25… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.
