CIFS performance Issue
by Tim Driggers 02 Apr '04

02 Apr '04

Hi All, I have been playing with an F760 with ONTAP 6.4.1 for about thirty days. I am having a problem understanding a CIFS transfer rate difference I am seeing between writing to and from the NetApp. First, a little background: The F760 has a X1025B gigabit card (SX fiber) in it, connected to an Extreme BlackDiamond 6808. The BlackDiamond does -not- have jumbo frames enabled at this time. The NetApp has full flow control configured. I am able to copy a single (30GB) file (generated by mkfile in FreeBSD) to and from the NetApp over NFSv3 at between 92-96mbit consistently, with the FreeBSD using an NFS mount having a 100mbit link. I am able to copy the same 30GB file from the NetApp to a Windows 2000 server using CIFS at 130-160mbit consistently. The Win2k server has a gigabit SX card. When copying the file to the NetApp from the Win2k server, I am seeing a maximum throughput of 69mbit, and usually it settles around 33-40mbit. I am monitoring this transfer rate using 'sh port utillization' on the BlackDiamond. I have tested this on three different Win2k boxes, with nearly identical results. I have also followed instructions on NetApp's website on how to 'improve' performance through registry edits, with no apparent result (positive or negative). I have tried three different flowcontrol settings on the Win2k cards (send, recieve and full) - again with no change in performance. I'm thrilled with the NFS performance, but we are a windows shop. I need to get performance increased on the CIFS writes to the NetApp if it's possible. I have tried every tweak I could find, and nothing seems to change the rate at which I can write to the NetApp via CIFS. I have included some NetApp information: slot 8: Gigabit Ethernet Controller II e8 MAC Address: 00:03:47:25:36:6a (auto-1000sx-fd-up) slot 9: NVRAM Memory Size: 32 MB netapp1> options cifs cifs.audit.autosave.file.extension cifs.audit.autosave.file.limit 0 cifs.audit.autosave.onsize.enable off cifs.audit.autosave.onsize.threshold 500k cifs.audit.autosave.ontime.enable off cifs.audit.autosave.ontime.interval cifs.audit.enable off cifs.audit.file_access_events.enable on cifs.audit.logon_events.enable on cifs.audit.logsize 524288 cifs.audit.saveas /etc/log/adtlog.evt cifs.bypass_traverse_checking on cifs.comment cifs.guest_account cifs.home_dir cifs.home_dir_namestyle ntname cifs.home_dirs_public_for_admin on cifs.idle_timeout 1800 cifs.max_mpx 50 cifs.netbios_aliases cifs.netbios_over_tcp.enable on cifs.nfs_root_ignore_acl on cifs.oplocks.enable off cifs.oplocks.opendelta 8 cifs.per_client_stats.enable off cifs.perm_check_ro_del_ok on cifs.perm_check_use_gid on cifs.restrict_anonymous.enable off cifs.save_case on cifs.scopeid cifs.search_domains cifs.show_snapshot off cifs.shutdown_msg_level 2 cifs.sidcache.enable on cifs.sidcache.lifetime 1440 cifs.snapshot_file_folding.enable off cifs.symlinks.cycleguard on cifs.symlinks.enable on cifs.tcp_window_size 64240 cifs.trace_dc_connection off cifs.trace_login off cifs.wins_servers <edited> netapp1> options ip ip.fastpath.enable on ip.ipsec.enable off ip.match_any_ifaddr on ip.path_mtu_discovery.enable on ip.ping_throttle.alarm_interval 0 ip.ping_throttle.drop_level 10 ip.tcp.newreno.enable on ip.tcp.sack.enable off If anyone can help, I would really appreciate it.

Hi Jack, We are currently using both vendors. In my view, a mixture of the both allows for coverge, if one of the vendors are a bit slow in reacting and releasing an update to cover a new virus type. The latest offering from Trend allows for one scanner to scan more than one NAS Appliance, which was a restriction that was becomming a pain to live with. I have had not seen McAfee for NetApps in action, but from reading the documentation it behaves in a similar way. Generally we run McAfee on Local client machines and Trend on Servers, and currently we are serving a user base of 5000+ users accross EMEA and have had no problems.

All that problems affected my selxual activity, my wife was not as happy as before with me. I tried Viagras - both genedric and Pfdizer's, but they does not act as good and as long as i want it to be. Finally, my colleague told me about Cialdis and i ordered it. The results were really better, trust a doctor. I'd recommend it to anybody with erectlion troubles. P.S.: By the way, you can mix Ciaplis with alcohol without any harm!

RE: NDMP performance with a 960
by John Clear 27 Mar '04

27 Mar '04

Many small files isn't too much of a problem on fulls, but is painful for incrementals. I have a 650GB qtree with 10 million files. The full takes about 16hrs, and the incremental takes 3-4hrs, most of which is just figuring out which files to back up. On both full and incrementals, no data is written to tape for the first 2+hrs. This isn't as big a deal on fulls (~40GB/hr average), but makes incrementals take much longer then similar sized volumes with fewer files. Once either the full or incremental starts moving data, the speed is similar to any other data. John

And if so, what happens if I add the following entry to the exports: /vol/vol1/dir/subdir -access=host3 Can host1 and host2 now only mount /vol/vol1/dir or can they still mount /vol/vol1/dir/subdir?

RE: exports and mount of subdirectories
by Krause, Oliver 22 Mar '04

Hi Thorsten, the " System Administration File Access Management Guide" says: How Data ONTAP matches mount requests with exported resources When Data ONTAP receives a mount request from a client, it compares the path name in the mount request to the path names of the exported resources. If Data ONTAP finds a match, the NFS client can mount the resource. Data ONTAP uses the longest matching prefix in the path name in determining access restrictions. Example Suppose you export both the /vol/vol0/home resource and the /vol/vol0 resource. When a host tries to mount the /vol/vol0/home/user1 directory, Data ONTAP applies the access restrictions specified for the /vol/vol0/home resource to determine whether the host should be granted access. Similarly, when a host tries to mount the /vol/vol0 directory, Data ONTAP applies the access restrictions specified for the /vol/vol0 resource.

I have made several enquiries to your Embassy to locate any of my clients relatives immediate and extended, and close business associates this has proved unsuccessful. After several unsuccessful attempts, I decided to trace his relatives over the Internet and locate any member of his family but of no avail. Hence,I am contacting you.I need you to assist in securing the money and property left behind by my client before they get confiscated or declared unserviceable by the bank where his huge deposits were lodged. Particularly, the bank where the deceased had a domicilliary account valued Twenty-six million, five hundred thousand ($26.5m) United States Dollars. The bank has issued a notice to provide the Next of Kin or have the account confiscated within the next one month. Since I have been unsuccesful in locating the relatives for over two years now I seek your consent to present you as the next of kin of the deceased since you have same surname so that the proceeds of this account valued at $26.5 million Dollars can be paid to you and then you and me can share the money. 60% to me and 35% to you,while 5% should be for expenses or tax as your government may reqiure. I have all necessary documents to back up claims as Next of Kin on your behalf. All I require is your honest cooperation to enable us see this deal through. I guarantee that this will be executed under a legitimate arrangement that will protect you from any breach of the law.

Hi To All Just to let you all have a chance, I have the responsibility to remove quantities of older Netapp equipment, such as;F230's, F330, F630's F540, C1100's and also SCSI shelves differential and single ended with 9gb drives and FC7's, I even have the storage 1 shelves single ended and differential with that the 4gb drives. F330 spares kit, as well I have power supplies for the storage 2 and FC7 shelves, NVRAM cards, networks cards, scsi cards. This inventory is at give away prices and some I will just give away and that's probably what I will do, donate to our Ottawa University's and Colleges. I also have none Netapp equipment. This is a large list over 350 items. These cover Sparc 5's,10's,20's, Ultra 10's, SUN clones Axil311's 320's, along with these we have scsi single connect, fast narrow and differential disks, video cards 13w3 and svga's. Cycle SUN clone MLB's, tape drives, cdrom drives, power supplies. SCSI bus and PCI adapters Anyway if you are interested give me a call or email would be great. Txs Peter Gauthier 613-721-3300 x6223

RE: RAID4 Catch-22
by Strange, Steve 17 Mar '04

Geoff, You'll need to boot with floppy boot option 29/7, which tells RAID to ignore media read errors. The reconstruct will then complete, but you'll want to run WAFL_check after that, since ignoring media errors means some blocks of data could be lost (user data or metadata). The RAID subsystem in ONTAP was rewritten in version 6.2, and reconstruct (among many other things) is much improved. We keep track of reconstruct progress between reboots, and in even more recent versions, we won't panic when we hit a media error during reconstruct. WAFL iron will allow you do do a sanity check on the volume following this, without having to bring the filer down for WAFL_check. Data ONTAP 6.5 features RAID-DP, or RAID double parity, which makes this problem disappear. The RAID group would then have double redundancy, and could handle a media failure during the reconstruct of a single disk without data loss or downtime. Any RAID-5 or RAID-4 system won't be able to handle this without at least some data loss. Hope this helps. Steve -----Original Message----- From: Geoff Hardin [mailto:geoff.hardin@dalsemi.com] Sent: Tuesday, March 16, 2004 6:23 AM To: toasters Subject: RAID4 Catch-22 We are stuck in a RAID 4 Catch-22 and we really can't see any way out of it. Here's the situation: I have a clustered pair of F760 filers running ONTAP 6.1R1P1. Early Monday morning, disk 6.20 (72 GB drive in a DS14 shelf) failed. Immediately, the filer began to rebuild on spare disk 6.29 and (because of the large size of the volume, approximately 800 GB), the reconstruction was still running at about 7 pm. It was at 7 pm that disk 6.25 experienced an unrecoverable read error on sector 128273044; however, since there is no parity disk available, the filer was unable to recover this data and the filer panicked and rebooted. Fast forward twelve hours and again we're about 90% done with reconstruction and disk 6.25 has an unrecovered read error on sector 128273044; the filer panics, reboots, and the countdown begins again. Does anyone know of any way out of this dilemma, short of restoring from tape? Many thanks in advance. Geoff Hardin UNIX System Administrator Dallas Semiconductor geoff.hardin(a)dalsemi.com
