High CPU
by Sayla, Mustafa 10 Jun '16

10 Jun '16

Is there a way to find out why in a CDOT cluster controller A is always between 50 and 55% CPU usage and controller B is less than 25%. Storage wise data is evenly balance but seem like some volumes are used more heavily than others and if I can identify them I would balance them to that CPU usage is even between the controllers.

Risk of assigning disks in a loop to two controllers
by BERNTSEN Basil 10 Jun '16

10 Jun '16

Hi folks, I have a CDOT 8.2 system (in prod) where new shelves were installed on a SAS stack on the wrong node. I want to create an aggregate on node1, but the disks are on node2. Based on the guidelines<https://library.netapp.com/ecmdocs/ECMP1196912/html/GUID-99C1AA7C-79D9-4E4F…>, I'm thinking of delaying the aggregate creation and changing the shelves. My question is whether it's worth the delay. What are the risks of just assigning the disks to the partner of the node they're currently assigned to? The documentation says to "Always assign all disks on the same loop or stack to the same system." Why? Thanks!

Closing cifs sessions by id in 8.2
by Basil 31 May '16

31 May '16

Hi, I'm running 8.2.3 and need to close a specific cifs session by ID for troubleshooting and taking a trace. The command cifs session close appears to have been introduced in 8.3... Is there another way, maybe from node or system shell, to kill a specific session?

Support Bulletin 7010246
by Philbert Rupkins 27 May '16

27 May '16

Toasters, Does anybody have more information on support bulletin 7010246? I just received an email urging us to upgrade to ONTAP 8.1.4 P9 as earlier versions of 8.1.4 are "more susceptible to potential system disruptions and/or data loss due to drive failures exceeding the two drive failure protection offered by RAID-DP." We've been planning to upgrade to P9 so this isn't that big of a deal. However, I'm just curious if this is a new development or has this always been a problem with pre-P9 releases of 8.1.4? The support bulletin is light on background information. If this hasn't always been an issue, the only logical conclusion I can come to is NetApp is shipping new replacement drives that don't play well with pre-P9 releases of 8.1.4. Thank you all very much. Phil

incorrect language for volume
by Darry Cooley 16 May '16

16 May '16

We are in the process of migrating data from our 7mode filers (8.1.2P4 7-Mode) to our new CDOT filers (8.3.1P1), and we noticed that a few of our 7mode volumes (NFS volumes) do not have the correct language set. 7mode documentation says I can change the language of a volume, however: Note: If you are changing the NFS character set, you are asked to confirm > your choice, and also whether you want to halt the system so that > WAFL_check can be run to check for any files that will no longer be > accessible using NFS. The default answer for this question is yes. If you > do not want to halt the system, you must enter n. > I'd really prefer to not halt the filer. What are the ramifications of not halting the filer? Can I safely change the language and snapmirror over to the new filers without issue? Thanks. ...Darry -- Darry Cooley Factory Systems Engineer Broadcom Limited - WSD FS/FAST 4380 Ziegler Road, Fort Collins, CO 80525 darry.cooley(a)broadcom.com

Listing NTFS style ACLs from unix client via NFS (Take 2...)
by John Adams 12 May '16

12 May '16

Hi all.. I asked this a few weeks ago: If a qtree is using NTFS style permissions, and that same qtree is exported via NFS to a unix client...Is there a way to see the NTFS acl's from that unix client? The usual "ls -l" just shows what looks like mode 777. I got some good responses, but I'm not seeing what I want to see. Qtree on filer is security style NTFS. Qtree is exported to linux box via export file on filer: /vol/secgroup_group -sec=sys,rw=mfanfs,root=x.x.x.x,nosuid Qtree is mounted on linux box: > mount -o vers=4,acl secgroup:/vol/secgroup_group /secgroup > grep secgroup /proc/mounts secgroup:/vol/secgroup_group/ /secgroup nfs4 rw,relatime,vers=4,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=x.x.x.x,minorversion=0,local_lock=none,addr=x.x.x.x 0 0 NFS option on filer: > options nfs.ntacl nfs.ntacl_display_permissive_perms on >From a windows box, using the CIFS share to that qtree, I can right click on a file, select security, and then see/set the usual NTFS style ACLs. When use getfacl from the unix box, I still only see the unix style (User,Group,Other) permissions. What I'm hoping to see is the Windows style ACLs that are on the files. I can see them from the filer: secgroup@testfs1> fsecurity show /vol/secgroup_group/ccc/pit [/vol/secgroup_group/ccc/pit - File (inum 28476)] Security style: NTFS Effective style: NTFS DOS attributes: 0x0020 (---A----) Unix security: uid: xxxx(username) gid: 101 (groupname) mode: 0777 (rwxrwxrwx) NTFS security descriptor: Owner: DOMAIN\username Group: DOMAIN\Domain Users DACL: Allow - DOMAIN\budget - 0x001f01ff (Full Control) Allow - Everyone - 0x001200a9 (Read and Execute) - (Inherited) Allow - DOMAIN\username - 0x001f01ff (Full Control) - (Inherited) Allow - DOMAIN\group - 0x001f01ff (Full Control) - (Inherited) I am hoping to be able to see the above output, from the linux client. I'm looking for a way for users on linux clients to see the windows ACLs that are on this NTFS qtree. Any suggestions? Thanks.

nfsstat in cmode 8.3
by Douglas Siggins 05 May '16

05 May '16

Greetings, Dipping my toes into cluster mode. It seems the ability to monitor specific nfs clients in 8.3 is no longer there? ::> statistics settings modify -display-rates true -client-stats enabled Warning: System performance may be significantly impacted. Are you sure? Do you want to continue? {y|n}: y ::> statistics show -object client I dont believe I am seeing the hostname field, has anyone used this prior? I know about nperf and pcpconfig in the sytemshell, but I'd prefer not to use "unsupported" tools.
