Creating a readonly user to monitor NetApp cluster via check_mk
by Sylvain Robitaille 20 Dec '18

20 Dec '18

Hello fellow toasters users ... We're in the process of deploying a pair of new CDOT filers and one of the things we'd like to setup with them is having check_mk (nagios and rrd, under the hood) monitor various attributes. We have a working instance at the moment using snmp to query the filers, but check_mk also provides a "plugin" that claims to work with the filer's web interface, so we'd like to examine that. To that end, I've setup a read-only user on the filer, that I intend will be able to access the web interface: security login create -vserver fc1-na -user-or-group-name nul_cmk \ -application http -authentication-method password -role readonly \ -comment "check_mk monitoring" The user shows up when I "show": fc1-na::> security login show -vserver fc1-na -user-or-group-name nul_cmk Vserver: fc1-na Second User/Group Authentication Acct Authentication Name Application Method Role Name Locked Method -------------- ----------- ------------- ---------------- ------ -------------- nul_cmk http password readonly no none The readonly role is unchanged from the OS default: fc1-na::> security login role show -vserver fc1-na -role readonly Role Command/ Access Vserver Name Directory Query Level ---------- ------------- --------- ----------------------------------- -------- fc1-na readonly DEFAULT readonly security none security login password all security login role show-user-capability all set all 5 entries were displayed. Trouble is that if I try to login to the web interface as that user, the browser stays "stuck" at the "Loading system details..." spinner widget. It's been there now for about two hours as I type this. Of course, check_mk's plugin logs a timeout while trying to access the interface. I fully suspect that I'm missing something, of course, but I'm afraid I haven't been able to find what that is. If someone out there has experience creating such a user for readonly access, a pointer to where I should be looking and/or documentation I should be reading would be hugely appreciated. (cli is preferred because it's easier to document what I've done that way, but if someone points me to resources in the web interface I'm sure I'll be able to find what I need at the cli.) -- ---------------------------------------------------------------------- Sylvain Robitaille syl(a)encs.concordia.ca Systems analyst / AITS Concordia University Faculty of Engineering and Computer Science Montreal, Quebec, Canada ----------------------------------------------------------------------

Audit logs for CIFS events
by Ian Ehrenwald 20 Oct '18

20 Oct '18

Good afternoon Is anyone making use of cDOT auditing capabilities on CIFS shares? I've set up a demo implementation to toy around with and the log output leaves something to be desired, in terms of immediate usefulness/understandability. I was hoping for something that I could hand off to an end user when they ask "why did file X get moved to directory Y?". My demo auditing policy only has file-ops enabled, and the demo share (on NTFS volume) I am testing auditing with has advanced auditing permissions Create Files/Write Data, Create Folders/Append Data, Delete Subfolders and Files, Delete, Change Permissions, and Take Ownership enabled against my demo user. When I connect to this share as the demo user and create a directory, copy a file into it, create a subdirectory, move the file into this subdirectory, I do indeed get logging events I can view with Windows Event Viewer. Technically auditing is working. However, it is difficult to actually put together a chain of events based on the logged information with just my single user access, nevermind thousands of users across hundreds of shares. What are other people using to make sense of this audit data? Exporting via XML instead of EVTX and feeding it to.. something? Custom parsers? Spending hours with the awful Event Viewer and filters when your boss's boss wants an explanation for why files moved? :) Ian Ehrenwald Senior Infrastructure Engineer Hachette Book Group, Inc. 1.617.263.1948 / ian.ehrenwald(a)hbgusa.com

Cluster lifs not consistent anymore after upgrade from 9.3 to 9.4
by Florian Schmid 18 Oct '18

18 Oct '18

Hello, I have upgraded our two node cluster from 9.3P7 to 9.4P2, because we got a new AFF system, which needed version 9.4. Since the upgrade, I have the problem, that I'm not able any more to revert one cluster lif on both nodes. For both nodes, it is the same cluster lif! Here our cluster lifs (already with the new AFF system): network interface show -vserver Cluster Logical Status Network Current Current Is Vserver Interface Admin/Oper Address/Mask Node Port Home ----------- ---------- ---------- ------------------ ------------- ------- ---- Cluster aff-01_clus1 up/up 169.254.45.231/16 aff-01 e0a true aff-01_clus2 up/up 169.254.43.102/16 aff-01 e0b true aff-02_clus1 up/up 169.254.173.54/16 aff-02 e0a true aff-02_clus2 up/up 169.254.163.234/16 aff-02 e0b true fas-01_clus1 up/up 169.254.4.144/16 fas-01 e0c false fas-01_clus2 up/up 169.254.130.246/16 fas-01 e0c true fas-01_clus3 up/up 169.254.131.229/16 fas-01 e0b true fas-01_clus4 up/up 169.254.168.120/16 fas-01 e0d true fas-02_clus1 up/up 169.254.89.228/16 fas-02 e0b false fas-02_clus2 up/up 169.254.106.140/16 fas-02 e0c true fas-02_clus3 up/up 169.254.26.197/16 fas-02 e0b true fas-02_clus4 up/up 169.254.4.232/16 fas-02 e0d true As you can see here, both lifs fas-01_clus1 and fas-02_clus1 are not at home. When I try to revert them or migrate to their home port, I get the same error. Migrating the lif to a different port is possible without any problems: network interface revert -vserver Cluster -lif fas-01_clus1 Error: command failed: LIF "fas-01_clus1" failed to migrate: failed to move cluster/node-mgmt LIF. network interface migrate -vserver Cluster -lif fas-01_clus1 -destination-node fas-01 -destination-port e0a Error: command failed: LIF "fas-01_clus1" failed to migrate: failed to move cluster/node-mgmt LIF. I have checked the physical port e0a and haven't found any issues and it was working nicely before... I even made a cluster switch upgrade two weeks before and I was able to revert all ports. I have disabled the port e0a, disabled the switch port and checked cable. Nothing changed. Here the port config: network port show -node fas-01 -port e0a -instance Node: fas-01 Port: e0a Link: up MTU: 9000 Auto-Negotiation Administrative: true Auto-Negotiation Operational: true Duplex Mode Administrative: auto Duplex Mode Operational: full Speed Administrative: auto Speed Operational: 10000 Flow Control Administrative: none Flow Control Operational: none MAC Address: 00:a0:98:3a:52:13 Port Type: physical Interface Group Parent Node: - Interface Group Parent Port: - Distribution Function: - Create Policy: - Parent VLAN Node: - Parent VLAN Port: - VLAN Tag: - Remote Device ID: sw1 IPspace Name: Cluster Broadcast Domain: Cluster MTU Administrative: 9000 Port Health Status: healthy Ignore Port Health Status: false Port Health Degraded Reasons: - network port show -node fas-01 -port e0c -instance Node: fas-01 Port: e0c Link: up MTU: 9000 Auto-Negotiation Administrative: true Auto-Negotiation Operational: true Duplex Mode Administrative: auto Duplex Mode Operational: full Speed Administrative: auto Speed Operational: 10000 Flow Control Administrative: none Flow Control Operational: none MAC Address: 00:a0:98:3a:52:15 Port Type: physical Interface Group Parent Node: - Interface Group Parent Port: - Distribution Function: - Create Policy: - Parent VLAN Node: - Parent VLAN Port: - VLAN Tag: - Remote Device ID: sw2 IPspace Name: Cluster Broadcast Domain: Cluster MTU Administrative: 9000 Port Health Status: healthy Ignore Port Health Status: false Port Health Degraded Reasons: - Port e0c is working without any problems. I made now some more tests and I found a strange issue with the cluster ping command. Nodes fas-02, aff-01 and aff-02 behave the same, all of them get the correct cluster addresses from network interface table, only fas-01 doesn't get any addresses here: Example with fas-02: cluster ping-cluster -node fas-02 Host is fas-02 Getting addresses from network interface table... Cluster aff-01_clus1 169.254.45.231 aff-01 e0a Cluster aff-01_clus2 169.254.43.102 aff-01 e0b Cluster aff-02_clus1 169.254.173.54 aff-02 e0a Cluster aff-02_clus2 169.254.163.234 aff-02 e0b Cluster fas-01_clus1 169.254.4.144 fas-01 e0c Cluster fas-01_clus2 169.254.130.246 fas-01 e0c Cluster fas-01_clus3 169.254.131.229 fas-01 e0b Cluster fas-01_clus4 169.254.168.120 fas-01 e0d Cluster fas-02_clus1 169.254.89.228 fas-02 e0c Cluster fas-02_clus2 169.254.106.140 fas-02 e0c Cluster fas-02_clus3 169.254.26.197 fas-02 e0b Cluster fas-02_clus4 169.254.4.232 fas-02 e0d Local = 169.254.89.228 169.254.106.140 169.254.26.197 169.254.4.232 Remote = 169.254.45.231 169.254.43.102 169.254.173.54 169.254.163.234 169.254.4.144 169.254.130.246 169.254.131.229 169.254.168.120 Cluster Vserver Id = 4294967293 Ping status: ................................ Basic connectivity succeeds on 32 path(s) Basic connectivity fails on 0 path(s) Here the example from fas-01: cluster ping-cluster -node fas-01 Host is fas-01 Getting addresses from network interface table... Getting addresses from sitelist... Local = 169.254.4.144 169.254.130.246 Remote = 169.254.89.228 169.254.106.140 169.254.45.231 169.254.43.102 169.254.173.54 169.254.163.234 Cluster Vserver Id = 4294967293 Ping status: ............ Basic connectivity succeeds on 12 path(s) Basic connectivity fails on 0 path(s) As you see here, fas-01 is missing a lot of addresses here and wasn't able to them from network interface table at all. When I explicit enable -use-sitelist true , I see the same behavior on all nodes, even on the new ones... Has someone from you ever had such an issue? My problem is, that the FAS system is not in support anymore and I can't create a ticket at NetApp. Hopefully someone can help here?! Best Regards Florian Schmid

7m -> cDOT question
by Ian Ehrenwald 18 Oct '18

18 Oct '18

Good afternoon I have a single node FAS2520 with 12x3t SATA internally running 8.2 7-mode at a remote site. I need to upgrade it to cDOT to match the rest of our environment. If I (roughly): - Purchase a second-hand DS4243 filled with disk - Attach this shelf to the FAS2520, create aggregate - Move the data volumes from the internal disk to this external shelf - Copy the cDOT bundle to the filer - Shut down the filer, disconnect the external shelf - Reboot the filer, wipe the config, 'install new software first' from the boot menu Would I then be able to reconnect the external shelf with the moved volumes and import them to cDOT? The reason I need to go this route is because there is not enough bandwidth and time at the site to SnapMirror the data to our data center and then suck it back down. I took a look at the 7mtt to do something like this but it looks like no matter the copy-free mode used, it still requires a separate controller running cDOT to attach the moved shelves to. Any other better options/ideas? Ian Ehrenwald Senior Infrastructure Engineer Hachette Book Group, Inc. 1.617.263.1948 / ian.ehrenwald(a)hbgusa.com

AFF Post Process Compression?
by Philbert Rupkins 17 Oct '18

17 Oct '18

Hello Toasters, I've come across several docs that make it clear that both secondary and adaptive post-process compression are not compatible with AFF systems. I have yet to find an explanation for this. Does anybody know why? My best guess is it will shorten the life of the SSD's. We have several large deduped-but-not-compressed volumes we're migrating from 8.1.4 7-Mode to AFF systems running ONTAP 9.2. I was hoping to run post-process compression on these volumes once cutover to the 9.2 system to reap additional savings. I'm currently looking into enabling compression before cutting the volumes over to ONTAP9. However, each volume has 70+ snapshots associated with them and I see best practices for compression suggest removing as many snpashots as possible before running the post-process job. Thank you, Phil

vol clone split
by Chris Hague 12 Oct '18

12 Oct '18

Hi Toasters, I have a number of volumes running from a common snapshot and would like to split them out. All these volumes are snapmirrored to our DR site. However, when I try to perform a vol clone split, it complains about an in-use snapshot. Reading further, it appears that the split will delete all snapshots, so doesn't like the snapmirror snap. What is the best way to split these volumes? Ideally without having to re-baseline \ lose my snapmirror destination volume \ snaps. ONTAP v9.1P2 Error below; Time Node Severity Event ------------------- ---------------- ------------- --------------------------- 8/30/2017 09:02:17 filer1 INFORMATIONAL mgmtgwd.jobmgr.jobcomplete.failure: Job "Clone Split" [id 6716] (Split vol1) completed unsuccessfully: Volume has locked snapshots (1). 8/30/2017 09:02:17 filer1 DEBUG wafl.config.req.error: Config request 'VV_CONFIG_REQ_CLONE_SPLIT_START' by WAFL for volume vol1 is not being processed because of the error: '387 - CR_VV_VOLUME_SNAPSHOTS'. 8/30/2017 09:02:17 filer1 NOTICE wafl.vv.clone.splitBusySnap: Volume 'vol1 has locked snapshots, not splitting.

FLI & Windows Clusters
by Chris Hague 10 Oct '18

10 Oct '18

Hi All, We have been using Foreign LUN Import to migrate 3rd party storage systems into CDOT. So far, we have been shutting down servers to perform the cutover. However we are now due to migrate some multiple node SQL clusters and looking at the possibility of using windows failover cluster manager to make these migrations non-disruptive. i.e. Failover node 1 resources to node 2 FLI node 1 LUN's & re-zone Failover node 2 resources to node 1 FLI node 2 LUN's & re-zone We are worried that if we fail over each windows node, migrate it's disks using FLI and change the zoning. When we failover the next node which still has direct access to the 3rd party storage, any writes made will not go through the LUN import relationship on CDOT and potentially cause corruption. Can anyone offer any advice on this? Many Thanks, Chris. This email is being sent by a subsidiary of Arthur J. Gallagher Holdings (UK) Limited, part of the Arthur J.
