Massive messages files.
by Jeff Cleverley 20 Jan '12

20 Jan '12

Greetings, I upgraded to 7.3.5.1P4 from 7.3.3P5 on January 1st. Since then my messages log files have gotten huge. My current one is 123 MB and the average size in December was 250K. I've always had the syslog.conf set up to send info levels to the messages file. Since the upgrade I've been getting a log of messages about things that used to never show up such as MNTPool and ExportPool entries. There are other entries that never showed up before either. I like having the info level because it shows me who is connecting via cifs, time stamp update, nis updates, etc. I would rather not have to change all the logging to the warning level. Parsing through messages files with 800k lines in it is not pretty :-) Is there another way to tune what shows up at the info level in 7.3.5? Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

v-filers and external network isolation
by Craig A. Falls 20 Jan '12

20 Jan '12

Good People, I am a long time reader, novice poster, and I have a question for you. I have a environment where I want to put a single physical filer across two distinct networks (one internal and once external). Using v-filers I want to provide services for both networks. Generally I would use two physical filers for this, so attacks on the physical filer in the external network would only compromise storage in the external network. In using a single physical filer, and using v-filers, I am hoping to achieve the same results, the issue is however that I can still get to v-filer0, and thus the filer as a whole from the IP address on the interface that is hosting the v-filers provisioned to the external network. Thus providing an attack vector to something that before (with two physical filers) was completely inaccessible. I see two possible solutions that I am not sure are implementable: (1) Somehow creating the interface connected to the external network without an IP address, thus v-filers would have IP address on that interface, and be accessible, but the v-filer0 would not be accessible, as there is no IP to access it, or (2) Somehow deny ssh to v-filer0 from the external network interface, but it would still have to work for the v-filers on that interface. Not sure if these are possible, or an extensive list of the ways to achieve what I am attempting. Also in re-reading this SSH isn't the only attach vector, http and any other management interface would have to be denied from the external interfaces as well. Any advice or thoughts would be much appreciated. thanks c

Head swap
by Simon Ogilvie 19 Jan '12

19 Jan '12

Hi all, I have a query regarding a head-swap upgrade which I've never attempted before, so any help would be much appreciated! We currently have a single-head FAS3020 running a small number of SATA and FC shelves. The head is EOL and so I've been able to persuade my bean counters to buy me a pair of FAS3240 heads to use as an HA pair. We're keeping all the disk shelves, so I "just" need to swap the heads over. From what I've read, it's best practice to upgrade the old head to the version of ONTAP that the new head will run, but we don't have that option as the 3020 won't run ONTAP 8 and the 3240's won't run ONTAP 7! This is our central storage system, using CIFS, NFS and LUNs over FC, so getting it wrong isn't really an option. Is this going to be achievable or should I call professional services in? I'd rather do this myself if possible, not least because PS are rather expensive... Can I just copy the latest ONTAP onto the existing vol0 and shut the head down, power up the new head and make the disks owned by the new head? I assume I'll also have to tell the FC switches about the new WWPNs for the LUNs to work. Will that work or will I end up with a very large, very expensive brick? Thanks! Simon.

cifs operations
by Crawford, Mark (CBC) 15 Jan '12

15 Jan '12

Hello toasters: Can anyone explain what CIFS operations that are neither read nor write operations? In addition, can anyone think of what process(es) could be causing these? ops/s reads(n, KB/s) writes(n, KB/s) suspect/s 860 | 0 0 | 0 0 | 0 | We have 1500+ windows 7 workstations connecting to their homeshares on this head. Lately we have been seeing CIFS latency where the user workstations are hanging within their windows explorer window. When this occurs, a cifs top shows high "ops/s" with no associated reads or writes. We are running DATA ONTap v7.3.5.1P1. Any insights would be greatly appreciated.

DS14MK4 as DAS
by Don Elmore 08 Jan '12

08 Jan '12

Apologies if this has been asked before. We have a DS14MK4 shelf with 144G FC disks and 2 ESH4 modules that's no longer in production. I've heard of people using these shelves as direct-attached storage (no filer head, just directly cabled to a host), but I haven't been able to pull up any details after searching online. I figure if anybody has tried something this silly, they're probably on this mailing list :) Has anybody been able to get this to work? Any tips/tricks? Thanks!

SNMP poll timeouts
by Jeff Cleverley 03 Jan '12

03 Jan '12

Greetings, I upgraded a 6080 and 6040 cluster from 7.3.3P5 to 7.3.5.1P4 this past Sunday. Since then I have been getting periodic timeout alerts followed by a resolved message on the 6080 cluster. I don't have any errors on the 6040 cluster. I didn't have any problem with either of these clusters at the old level. I'm sure I can have our NMS manager adjust timeouts or retries, but this is basically masking the issue. The filer doesn't seem to be particularly busy and the network interfaces are not showing any obvious issues. Does anyone have any idea of what may have changed in the release and why it is only affecting the 6080 cluster?

64 bit root volume conversion.
by Jeff Cleverley 31 Dec '11

31 Dec '11

Greetings, We have a filer (3140) running 8.0.1 and the group wanted to convert it to a 64 bit root aggregate and vol0. I let them practice on my 8.1 test box and everything went as planned. When they did it on their 8.0.1 box, all went as plan except for the assigning the root volume. They had moved the original vol0 out of the way and renamed the new 64 bit volume to vol0. When they ran the "vol options vol0 root" command it gave the following output: >> Necessary system files are not present on the volume 'vol0'. It is recommended that you copy system files from the current root volume to the new root volume using the steps outlined in System Administration Guide, chapter 'Understanding Root Volumes', section 'Changing Root Volume'. If you do not, then after reboot, the appliance will enter setup and service will be disrupted until all the setup steps (including a reinstall of system software) have been completed. Continue with set root operation (y/n)? >> He answered no. We did file listings and verified all the files are in both places. There were no obvious ndmpcopy errors. The size of space used differs a little bit, but I assume the 32 vs 64 bit aggregate layouts would cause some fluff. I even had him destroy the 64 bit vol0 volume and run everything again. Same results. Does anyone know what this is complaining about? Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

ndmp restores
by Ian Dotson 21 Dec '11

21 Dec '11

We've just started using our first Netapp here. One surprise involves backups (we're using NetVault's NDMP plugin). I'll let our local backup guy explain: "We're setting up our new netapp, have the ndmp plugin in place and can back up ok. But I don't see how to set up backups of netapp filer volumes so that I can do restores in the same way we can do restores from windows file servers. Specifically, the ndmp restore window only shows the files backed up in that specific dump, so if I want to restore all files that existed in a directory up to that date, it appears I have to separately do a restore of the level 0 dump, then all pertinent level 1 dumps, then all pertinent level 2 dumps, etc. With windows file restores, I could restore the whole directory with one job. How do I set up the netapp ndmp to work like that? " The NetVault folks reply that "the NDMP protocol doesn't allow for that. Each restore builds on the previous restore, so you have to do Level 0, Level 1, etc.. It would be the same with any filer that utilizes the NDMP protocol" -- which doesn't seem right at all. So, is this indeed the same for those using NetBackup, etc.? Are you forced to restore each dump level individually? Thanks, Ian Dotson

Flex_scale licensing question.
by Jeff Cleverley 20 Dec '11

20 Dec '11

Greetings, I'm confused about the flex_scale licensing. We have installed PAMII modules in 2 of our clusters running 7.3.x. We have a license for pamii, but not for flex_scale. To manage the extended cache, it has us set flexscale.xxx options. Since we don't have flex_scale licensed, are these options doing any good at all? I didn't know if flex_scale was tied to the old flashcache modules and pamii now incorporates the same thing for the new PAMII cards. Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611
