List administrivia
by Tom Yates 31 Oct '11

Regarding out-of-sequence messages: yes, I'm aware that messages are arriving out-of-sequence again. This is caused by people posting from addresses other than those by which they are subscribed. In what I think is fairly standard anti-spam behaviour for 21st Century mailing lists, this one holds (for moderation) posts from apparently-unsubscribed users. For fastest, and therefore sequential, throughput, *please post from the address at which you have subscribed*. Regarding … [View More]

Is there a graph somewhere of performance vs raid group size?
by Cotton, Randall 31 Oct '11

31 Oct '11

We're a relatively small shop just getting started with NetApp (1 2020 and 2 2040's all active/active, plus 3 4342's for the 2040's ). Since committing a disk to a raid group via an aggregate is essentially a permanent thing (you can't change your mind and later shrink an aggregate to pull out a disk from a raid group to use with another node), we'd prefer not to put all our (80) disks in aggregates just yet. We might want more in some nodes and less in other nodes as future needs come into … [View More]

8.1 64 bit upgrades.
by Jeff Cleverley 22 Oct '11

22 Oct '11

Greetings, I've starting playing around with the 8.1 RC1 release. I want to upgrade some aggregates from 32 bit to 64 bit. From what I can tell, the only way to do this is to add additional disks to an existing aggregate. Is that correct? I've got one filer with limited disks and don't want to add 1 additional disk to a raid group. I don't want to do all the associated reallocates to smooth out the data allocation. Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler … [View More]

TOE fun?
by Mark Flint 21 Oct '11

21 Oct '11

Hi all, I recently upgraded a V3140 to 8.0.2P1, and all went well apparently. I'n now seeing strange NFS/CIFS behaviour, where a client will make a connection succesfully, but when the client requests a read, the filer FIN ACK's instantly, for no reason I can work out. Got a call open with netapp, but they seem a little fazed by it as well. Anyone seen something similar and can point me? It does seem like it's a TOE problem, but I have TOE turned off on the NIC's, but am wondering if ONTAP is … [View More]

by Luca Domenella 13 Oct '11

Hi guys, i have 2 fas2050a used only with NFS protocol. I need to reinstall one from scratch and snapmirror the data in it. After that I want to swap (one by one) the heads from the other fas2050a in order to dont change the support contract from this storage. Do you see any issue in performing the head swap ?

weird name mapping issues - using LDAP for name services
by Page, Jeremy 13 Oct '11

13 Oct '11

We are using Active Directroy for LDAP on our Linux clients. I'd like to set up the filer to be able to resolve the usernames both directions but I'm having a couple of issues. Filers are running 7.3.3. I have had this working before at a previous job but I am missing something & the docs are not quite as helpful as I'd like. 1) I can't get LDAP working at all (getXXbyYY is not working even though I see the filer connecting to the DC on the appropriate port but I'm missing … [View More]something. 2) Not all users have rfc2307 information set, ideally I'd use their samaccountname for both (it always matches). 3) I am in a multiforest environment, I'd like to use Global Catalogs for my lookups instead of normal DC's & do it on the GC port so it can retrieve info for any user on my network. This may not be possible, I am not sure. NIS works fine, if I am not able to get this to work I'm either going to have to script a dump of AD to NIS or use the MS tools to do the same thing and do this with a usermap.cfg. Either possibility is ugly so any suggestions would be appreciated. I've tried changing the ldap.minimum_bind_level to simple but it does not appear to help. dr-array02*> options ldap ldap.ADdomain ldap.base dc=site,dc=company,dc=com ldap.base.group dc=site,dc=company,dc=com ldap.base.netgroup ldap.base.passwd dc=site,dc=company,dc=com ldap.enable on ldap.minimum_bind_level anonymous ldap.name cn=ldap-auth-proxy,ou=ldap,ou=services,dc=site,dc=company,dc=com ldap.nssmap.attribute.gecos gecos ldap.nssmap.attribute.gidNumber gidNumber ldap.nssmap.attribute.groupname cn ldap.nssmap.attribute.homeDirectory unixHomeDirectory ldap.nssmap.attribute.loginShell loginShell ldap.nssmap.attribute.memberNisNetgroup memberNisNetgroup ldap.nssmap.attribute.memberUid memberUid ldap.nssmap.attribute.netgroupname cn ldap.nssmap.attribute.nisNetgroupTriple nisNetgroupTriple ldap.nssmap.attribute.uid uid ldap.nssmap.attribute.uidNumber uidNumber ldap.nssmap.attribute.userPassword userPassword ldap.nssmap.objectClass.nisNetgroup nisNetgroup ldap.nssmap.objectClass.posixAccount posixAccount ldap.nssmap.objectClass.posixGroup posixGroup ldap.passwd ****** ldap.port 389 ldap.servers vm-sitedc01.site.company.com ldap.servers.preferred ldap.skip_cn_unescape.enable on ldap.ssl.enable off ldap.timeout 20 ldap.usermap.attribute.unixaccount uid ldap.usermap.attribute.windowsaccount sAMAccountName ldap.usermap.base ldap.usermap.enable on Please be advised that this email may contain confidential information.

Migrate Solaris FC LUN to Linux iSCSI ?
by Steve Losen 11 Oct '11

11 Oct '11

Hi toasters, Is it possible to take a Solaris FC LUN and attach it to Linux via iSCSI? I suspect problems since the "lun create" command needs to know the OS type (solaris in this case). I don't think FC to iSCSI is a problem, though. Naturally we would love to "just move" the LUNs without creating new Linux LUNs and copying the data from Solaris to Linux. In case you are wondering about the FS on the LUNs, this is disk cache for a StorNext filesystem and we want to replace our very old … [View More]

Snapvault advice
by Unnikrishnan KP 07 Oct '11

07 Oct '11

Hello all, We are planing a snapvault backup of data from a snapmirror destination. Most of the volumes that are to be snapvaulted are luns in qtrees. The rest are nas data. I was looking at different ways to do this and came up with the following conclusion for block data: 1. Run a snapvault update on the _recent copy. Schedule a snapvault snap sched on the secondary after the update. This require a bit of scripting and schedules. 2. The best practises guide recommends using the … [View More]
