Distribute aggregate across shelves or limit to one shelf?
by Ray Van Dolson 08 Apr '11

08 Apr '11

Best practice (based on my reading of the archives) seems to be to distribute disk membership in an aggregate across disk shelves. This would appear to be for performance reasons primarily (less chance of saturating a shelf's "uplink" to the controller), but how does it affect reliability? If I limit myself to one aggregate per shelf, if I lose that shelf I lose only the one aggregate. If aggregates are distributed I could lose all of them. My thought is that the chance of the shelf failing is actually pretty slim as its hardware isn't all that sophisticated. And obviously there are performance penalties for limiting to one aggregate per shelf (disk count maximums). Thanks, Ray

Has anyone seen an issue where the filer did not update the SNMP settings when set via FilerView? Like changing/modifying the community strings or trap destinations?

Is anyone running ONTAP 8.x with 64 bit aggrs ?
by Steve Losen 06 Apr '11

06 Apr '11

Hello Toasters, Currently all of our filers are running ONTAP 7.3.x and we are looking at upgrading to 8.x and perhaps buying some disks/shelves that require 8.x. We would also like to convert to 64 bit aggrs to get beyond the 16T size limit. As I understand it, there is no way to upgrade an existing 32 bit aggr to 64 bit in place, you need to copy the data. Furthermore, you cannot volume snapmirror 32 bit to/from 64 bit. I presume you can ndmpcopy 32 bit to/from 64 bit. How about "vol copy" ? Is anyone running 8.x and migrating from 32bit to 64bit aggrs? How are you doing it? Is the recommended 8.x release stable? Any serious bugs, issues, or gotchas ? Thanks, Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

DFM 4.01 fragmentation on windows 2003 server
by steve klise 01 Apr '11

01 Apr '11

I have a vm running windows 2003 with DFM on it monitoring a few filers. Its been running for years, and I have gone from DFM 3.3 on up to 4.x. The question is this. The drive that has the application installed on it is heavily fragmented. All the fragmentation is in the perf data type files. Any thoughts? I have run the defrag multiple times. 12,610 7.26 GB \Appspub\DFM\DFM\perfdata\perf_8_21270_1331 9,746 8.19 GB \Appspub\DFM\DFM\perfdata\perf_183_5279_12249 8,363 7.46 GB \Appspub\DFM\DFM\perfdata\perf_8_21270_5022 6,523 1.65 GB \Appspub\DFM\DFM\perfdata\perf_8_282_1333 5,505 264 MB \Appspub\DFM\DFM\perfdata\perf_245_5390_4 4,483 3.52 GB \Appspub\DFM\DFM\perfdata\perf_205_5281_1310 2,941 4.64 GB \Appspub\DFM\DFM\perfdata\perf_8_5279_5808 2,433 4.33 GB \Appspub\DFM\DFM\perfdata\perf_8_5279_5425 2,256 4.73 GB \Appspub\DFM\DFM\perfdata\perf_8_5279_5881 2,028 4.59 GB \Appspub\DFM\DFM\perfdata\perf_205_5281_2356 1,943 190 MB \Appspub\DFM\DFM\perfdata\perf_4_21270_3 1,224 1.74 GB \Appspub\DFM\DFM\perfdata\perf_205_5281_2541 1,063 3.51 GB \Appspub\DFM\DFM\perfdata\perf_183_5279_12995 1,017 1.72 GB \Appspub\DFM\DFM\perfdata\perf_205_5281_2539 966 2.33 GB \Appspub\DFM\DFM\perfdata\perf_8_5279_2658 866 160 MB \Appspub\DFM\DFM\perfdata\perf_1_21270_13 770 121 MB \Appspub\DFM\DFM\perfdata\perf_6_26686_8 724 3 MB \Appspub\DFM\DFM\log\dfmwatchdog-0.log 718 3 MB \Appspub\DFM\DFM\log\dfmwatchdog-1.log 681 416 MB \Appspub\DFM\DFM\perfdata\perf_184_5279_141 645 3 MB \Appspub\DFM\DFM\log\dfmwatchdog-2.log 615 3 MB \Appspub\DFM\DFM\log\audit-2.log 614 3 MB \Appspub\DFM\DFM\log\audit-1.log 585 3 MB \Appspub\DFM\DFM\log\audit-0.log 580 2 MB \Appspub\DFM\DFM\log\dfmwatchdog.log 561 5.27 GB \Appspub\DFM\DFM\perfdata\perf_8_21270_4561 525 290 MB \Appspub\DFM\DFM\perfdata\perf_9_21271_62 517 173 MB \Appspub\DFM\DFM\perfdata\perf_242_5390_26 499 2.84 GB \Appspub\DFM\DFM\data\monitordb.db 485 714 MB \Appspub\DFM\DFM\perfdata\perf_9_10195_134 -- View this message in context: http://old.nabble.com/DFM-4.01-fragmentation-on-windows-2003-server-tp31174… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

LUN has run out of space
by Milazzo Giacomo 24 Mar '11

24 Mar '11

Hi all, I've a strange issue on a filer deeply used in FC SAN (3160 with DoT 7.3.2P6 -> it will be upgraded but for now is impossible). On a W2K8 server running Exchange 2010 a mailbox store is hosted on a LUN with this characteristics. The LUN has been created with Snapdrive. Volume /vol/excmbs2FAB01Data/ 155GB 100GB 54GB 65% /vol/excmbs2FAB01Data/ /vol/excmbs2FAB01Data/.snapshot 0KB 2110MB 0KB ---% /vol/excmbs2FAB01Data/.snapshot Vol options are Nosnap on Snap reserve/sched 0 Volume reservation "volume" Fractional reserve 0 Autosize on Volume autosize is currently ON for volume 'excmbs2FAB01Data'. The volume is set to grow to a maximum of 240 GB, in increments of 10 GB. Snap autodelete on Asis is on with a 20% space saved And the LUN /vol/excmbs2FAB01Data/excmbs2FAB01Data 150.0g (161067432960) (r/w, online, mapped) Comment: " " Serial#: W-PqRo/BiR8t Share: none Space Reservation: disabled Multiprotocol Type: windows_2008 Maps: viaRPC.21:00:00:24:ff:04:15:94.SRSEDEEXCMBS2=2 viaRPC.21:00:00:24:ff:04:15:91.SRSEDEEXCMBS2=2 The only snap in the volume comes from a Snapmirror relationship and it takes roughly 2 GB Volume excmbs2FAB01Data working... %/used %/total date name ---------- ---------- ------------ -------- 2% ( 2%) 1% ( 1%) Mar 23 15:03 netapp2040fab1(0135099451)_excmbs2FAB01Data.2 (snapmirror) As you can see the LUN is written by host for only 100 GB but sometimes it happens that the autogrow starts and on the console this messages are logged: Thu Mar 24 16:01:39 CET [netappfa1: wafl.vol.autoSize.done:info]: Automatic increase size of volume 'excmbs2FAB06Data' by 10485760 kbytes done. Thu Mar 24 16:04:56 CET [netappfa1: scsitarget.lun.noSpace:error]: LUN '/vol/excmbs2FAB01Data/excmbs2FAB01Data' has run out of space. Looking for details on NOW I've found no docs on this issue (just one regarding rws issues) and sincerely I cannot understand the reasons of this "out of space" messages. I've other LUNs configured exactly in the same manner without issues. Any idea? Dott.

What if SnapMirrror Cannot Keep Up
by Timothy Hollingworth 23 Mar '11

23 Mar '11

So if a source/destination pair is doing a snapmirror update and the current update is not complete before a new update is requested, what is the behavior? Does it queue the second snapmirror update and just update it when the first completes? I understand the behavior when updates are done by the scheduler on the array itself as per snapmirror.conf. In this case it queues the updates but only to a maximum of three. "If an update is in progress when another is scheduled to occur, SnapMirror starts another transfer as soon as the transfer is complete. However, if three updates pass while the current transfer is in progress, SnapMirror does only one more update; it does not go back and run updates that have been made obsolete by those scheduled later." But I'm not talking updates initiated by the scheduler on the array itself. I'm really asking about something like SME performing a backup and requesting an update. The snapmirror update here is functionally equivalent to issuing a snapmirror update command manually. Suppose the mirror does not complete before the next backup and subsequent update request is made (or snapmirror update command issued manually). What if the rate of data change exceeds the ability of network to complete the mirror or if the WAN link to the DR site is just too darn slow? Do the updates queue on the destination and snapshots build up on the source indefinitely? Or do manual or snapmanager initiated updates follow the "queue to three and then give up" rule above?

AW: RE: Problems with too many cifs clients behind a single IP NAT device?
by Zeitschel, Philipp 23 Mar '11

23 Mar '11

Hi, Cifs got a problem with nat and more user accounts on one ip. There is a cifs option that you can try. the option is called cifs.client.dup-detection and is set default to ip-address Try name, for detection through netbios or set it to off Cifs client detection is a option to detect duplicate sessions in order to terminate any session that did not terminate when a client system rebooted Hope that helps, greetz Philipp
