RE: Upgrading firmware
by Noll, Kevin 21 Feb '02

21 Feb '02

We have a 2 x F820 clustered. We have experienced 2 hardware failures on one of our F820 is the space of 1 week. During these hardware failures, the filer didnt manage to do a failover automatically. We had to do a force take over. All configs are identical as per cluster options. The only thing I see is that time clock is out of sync, which was caused during an upgrade in DataOnTap. (Known Bug) What I would like to know is if this is normal behaivour with clusters and hardware failure, and can the time sync be the problem that is stopping the live Netapp from automatically taking over the failed Netapp. Kevin -----Original Message----- From: Coatney, Sue [mailto:Sue.Coatney@netapp.com] Sent: 21 February 2002 02:25 To: 'Daniel Jung'; toasters(a)mathworks.com Subject: RE: Upgrading firmware > Also, I've heard that you "can" upgrade disk firmware while > having both > filers ON-LINE and clustered.

File access via Windows (laptops)
by Steve Turner 21 Feb '02

21 Feb '02

We are running a Netapp F820, NetApp Release 6.0.1R3. I finally got our Netapp setup to allow windows users to access files (specifically the users home directory). As long as the user is on a PC that logs into the domain, they can access the files without any problems. We have serveral users that use laptops and do not login to the domain. They cannot access any shares on the netapp. They have accounts on the win2k server and can access files on the windows server. If I change the laptop so that they are logging into the domain, it works. no problems. When users are on the road and/or accessing our network via VPN, it would be difficult for them to login to the domain. Is there a workaround? Any suggestions would be appreciated, Please let me know if you need more info. Thanks, Steve ---------------------------------- Mitsubishi Electric and Electronics Design Engineering Center - East Durham, NC

Slow writes
by edward valencia 21 Feb '02

21 Feb '02

Hi all, I hope that someone has gone through this as I have been trying to figure this out and its making me go nuts. On our solaris(2.8, 2.6) we usually do small file writes, our users do cvs checkouts to thier home directories and compile software that they are working on in that directory also. The problems is not the reads but the writes, I have changed the client machines to nfs3/tcp with rsize and wsize or 32k. The avg time todo a cvs checkout has been about 24 seconds, if this is done to local disk we are seeing the avg. of 4 seconds. The size of the module they are checking out is 4mb, this is what I have been doing tests with, but other cvs modules are also slow while being written to the nfs mount home directory. The filers also have the nfs.tcp.xfersize of 32k. Here are the configs of the filer: F760 NetApp Release 6.0.1R3: Fri Feb 16 02:42:49 PST 2001 e0: flags=8042<BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.174.32.67 netmask 0xffffff80 broadcast 10.174.32.127 ether 00:a0:98:00:56:a3 (auto-100tx-down) e4: flags=900042<BROADCAST,RUNNING,TCPCKSUM> mtu 1500 inet 10.174.32.126 netmask 0xffffff80 broadcast 10.174.32.127 ether 00:60:cf:20:31:fb (1000fx) e6: flags=848043<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.174.32.7 netmask 0xffffff80 broadcast 10.174.32.127 ether 00:90:27:f4:5b:0e (auto-1000sx-fd-up) flowcontrol full lo: flags=948049<UP,LOOPBACK,RUNNING,MULTICAST,TCPCKSUM> mtu 9188 inet 127.0.0.1 netmask 0xff000000 broadcast 127.0.0.1 We currently only use e6. nfs.mount_rootonly on nfs.per_client_stats.enable off nfs.tcp.enable on nfs.tcp.xfersize 32768 nfs.udp.xfersize 8192 nfs.v2.df_2gb_lim off nfs.v3.enable on nfs.webnfs.enable off nfs.webnfs.rootdir XXX nfs.webnfs.rootdir.set off malibu> sysconfig -r Volume vol0 (root, zoned checksums) RAID group 0 RAID Disk HA.ID HA SHELF BAY CHAN Used (MB/blks) Phys (MB/blks) --------- ----- ------------ ---- -------------- -------------- parity 7.13 7 1 5 FC:A 8600/17612800 8683/17783112 data 7.14 7 1 6 FC:A 8600/17612800 8683/17783112 data 7.1 7 0 1 FC:A 8600/17612800 8683/17783112 data 7.12 7 1 4 FC:A 8600/17612800 8683/17783112 Volume vol1 (zoned checksums) RAID group 0 RAID Disk HA.ID HA SHELF BAY CHAN Used (MB/blks) Phys (MB/blks) --------- ----- ------------ ---- -------------- -------------- parity 7.3 7 0 3 FC:A 8600/17612800 8683/17783112 data 7.2 7 0 2 FC:A 8600/17612800 8683/17783112 data 7.4 7 0 4 FC:A 8600/17612800 8683/17783112 data 7.5 7 0 5 FC:A 8600/17612800 8683/17783112 data 7.6 7 0 6 FC:A 8600/17612800 8683/17783112 data 7.8 7 1 0 FC:A 8600/17612800 8683/17783112 data 7.9 7 1 1 FC:A 8600/17612800 8683/17783112 data 7.10 7 1 2 FC:A 8600/17612800 8683/17783112 Here is a copy of sysstat when doing the write to the nfs dir: malibu> sysstat -x 1 CPU NFS CIFS HTTP Total Net kB/s Disk kB/s Tape kB/s Cache Cache CP CP Disk in out read write read write age hit time ty util 2% 0 0 0 0 0 0 0 0 0 0 >60 100% 0% -

Toasters - How can one forward auditlog events to syslog
by Alek O. Komarnitsky (N-CSC) 20 Feb '02

20 Feb '02

I've searched the archives for the answer to this question and searched with Google, but have not found it ... yet! ;-) We use syslog quite a bit to log stuff remotely, but there are certain events (such as root rsh activity) that are logged into auditlog that do NOT show up in syslog - we are logging *.info. Is there a way to get those events also sent to syslog so that we can use what is defined in /etc/syslog.conf to forward those events to our loghosts? Thanx, alek

Upgrading firmware
by Daniel Jung 20 Feb '02

20 Feb '02

Hi Fellow toasters, I need to upgrade OnTap on the couple of F840s that is clustered. According to the NOW site, it is recommended that I should bring down both filers and do disk firmware upgrade on one while the other filer is halted. Is this really necessary? What I planned to do was to upgrade OnTap on one of the filers (while clustering is disabled) first before I bring down the second one. Is this more dangerous than what NOW site recommends? Also, I've heard that you "can" upgrade disk firmware while having both filers ON-LINE and clustered. Is this true? Thanks Daniel Jung System Administrator GMO inc

RE: Reset of Archive bit causing very large backups

Robert, We experienced the exact problem that you describe, except with an F760 running a different ONTAP version. There is an ONTAP bug detailed in NetApp Bug ID #49892 that might help you out. The fix for us was to upgrade to 6.1.1R2P1 which solved the problem. I hope that helps.

A full backup will take up approx. 340GB of tape, however our differential backups are taking up on average 80GB. Last week we saw two consecutive differential backups of 240GB and 340GB.

While investigating this we noticed that files not accessed in a long time (6+ months) were still showing their archive bits set. As these files have not been changed in sometime the archive bit would be expected to not be set. Sure enough, on all files we looked at, the archive bit was set on all. Is this a bug?

MySQL on a filer...
by johnd＠energis2.net 18 Feb '02

18 Feb '02

A quick question for all you good people in Toaster List Land. Has anyone had any experience of running a (busy) MySQL DB off a filer? We'd quite like all the nice, scrummy data-protection features of a proper filestore but, well, you know, NFS and databases. Are we mad, or will it work? We have Filers aplenty so we can mess around, but the databases are all a bit company-critical so we're being cautious. We know it will *basically* work, but performance issues are the main worry. The DB has to be reasonable quick still, and random block access isn't a NAS strong point. So, any previous wins or horror stories?

This worked, thanks. Thanks also to the others who sent the same information and other helpful information and suggestions. I will also look into getting the upgrade as someone pointed out that the newer version is more win2k friendly. I think I will get a netapp class out of this also :).

If this isn't working, something else is wrong so you should open a case with netapp customer support.

what disks can i use in an F330?
by Brian Hechinger 17 Feb '02

17 Feb '02

i've got an F330 that i'd like to get online one of these days, and i'd like to get the most storage onto it that i possibly can. it's got 5 narrow SCSI channels on it, and i have a whole slew of DEC BA350 StorageWorks shelves to hook up to it. what is the largest size drives i can put on this thing? is there a particular model of drive that i am limited to? also, what are my options for a wide scsi controller or two in this thing? several of the BA350 shelves have 16-bit personality cards in them, and i'd love to be able to take advantage of that rather than downgrade them to 8-bit personality cards. i think that's all the questions i have for now. next step after getting disks on it, find a copy of the OS for it. -brian

ASYLUM CAMP Abidjan COTE D'IVOIRE Tel : 225-07-82-23-21 Attn: President/CEO CONFIDENTIAL I am well confident of your capability of executing this business for the mutual benefit of our both families, believing that you will not expose or betray the trust and confident I am about to repose on you. I am contacting you with the greatest delight and personal respect. I am Stella Kamara, the first daugther of Chief Kamara Raymond former minister of Mineral Resources of the Republic of Sierra-Leone who was recently murdered by the Forces Loyal to Corporal Foday Sankoh, due to his support to the incumbent elected President Tejan Kabbah to remain in the office as reported on the cable Network News (CNN) and by the British Broadcasting Corporation (BBC). Two days before my father was assassinated, he confided in me and ordered me to go to his underground safe and moved out immediately with the deposit agreement and cash receipt he made with a Security Company in Abidjan where he deposited one trunk box which contains cash sum of US$30,000,000 (Thirty million United States Dollars). I successfully smuggled out of the country to Abidjan, Côte d'Ivoire with the help of some rebels loyal to My father and have gone to the Security Company with the deposit agreement to confirm the deposit myself and also I have been granted political stay by the government of Côte d'Ivoire. Unknown to the Security company my father declared the contents of the trunk as African Artworks belonging to his foreign partner, that the keys are with him in order to prevent them from knowing the real content. I am now seeking for your direct assistance to front you as the owner of the consignment and lift the fund out of this country to your base for onward profitable investment which necessitated my contacting you and you will have 13% out of the money. We are to open a non residential bank account here in Abidjan in your name through which the fund will be remitting from to your bank account abroad and your reward for this noble assistance is under negotiable. Further detail will be made known to you on confirmation of your interest to assist me towards this project. Contact me through the above telephone and fax numbers .

What is the wafl command to check the layout of data, etc. thanks art -----Original Message----- From: Jeff Kennedy [mailto:jlkennedy@amcc.com] Sent: Wednesday, February 06, 2002 6:21 AM To: EH(a)dataconnection.com Cc: Mike Ball; Toasters (E-mail) Subject: Re: Slow write performance This was an issue for sure, I've been through it myself. However, you can use the wafl commands to check the layout of data and, if necessary, re-stripe it.

However, if the length of a file is 64 bytes or less, then the file data is stored in the inode and no data blocks are consumed. WAFL uses the space in the inode that otherwise holds the data block list. This is nice because most symbolic links are small enough to fit in the inode.

Block sizes
by Edward Hibbert 14 Feb '02

14 Feb '02

A question about block sizes on NetApp disks. My impression is that disk access occurs in blocks. So if I write 1 byte to a disk, at some level the OS has a block in cache, updates the block, then writes that block out to disk. If I write 20K, then it probably affects multiple blocks. If this is true, then it might be useful to know the underlying block size - because if I could ensure that my application wasn't spanning multiple blocks when I didn't need to be, I could give the physical disks a bit less of a hard time. Does anyone know how to find this out? Or is this all wrong, and the access doesn't occur in blocks? Thanks, Edward.

FW: microsoft dfs and cifs.homedir
by Uren, Jim 14 Feb '02

14 Feb '02

most of the old-timers already know this, but Colin points out that this is hard to find in the documentation...for scripting and such, using the share-name CIFS.HOMEDIR will cause the filer to connect "you" with "your" CIFS home directory (if such a homedir exists and if no actual share named CIFS.HOMEDIR exists). for Ontap 6.0 or above, the share name ~ (tilde) also works. for example, net use * \\filer\cifs.homedir will connect me to \\filer\joe-user if I am logged on as joe-user, or will connect me to \\filer\Administrator if I am logged on as Administrator, and so on. > in your place, I would create a Dfs > entry like this > \\DfsServer\Dfsroot\filerHome --> \\filer\cifs.homedir > or like this (if using Ontap 6.0 or above) > \\DfsServer\Dfsroot\filerhome --> \\filer\~ > > "cifs.homedir" and "~" are mapped by the filer to > "my CIFS homedir" (if such a homedir exists). > > Jim Uren, who hasn't tried this himself.

Edward, What do your Solaris systems look like? There are a number of things that can be done to get Sun systems, and especially their NICs, to coexist with Filers. I'm currently having a lot of fun getting some temperamental SBUS Gigabit NICs to perform up to spec (same problem - writes take FOREVER) Michael edward valencia <edjv(a)corp.earthlink.net> Sent by: owner-toasters(a)mathworks.com 02/13/02 05:14 AM To: "toasters(a)mathworks.com" <toasters(a)mathworks.com> cc: Subject: Slow writes Hi all, I hope that someone has gone through this as I have been trying to figure this out and its making me go nuts. On our solaris(2.8, 2.6) we usually do small file writes, our users do cvs checkouts to thier home directories and compile software that they are working on in that directory also. The problems is not the reads but the writes, I have changed the client machines to nfs3/tcp with rsize and wsize or 32k. The avg time todo a cvs checkout has been about 24 seconds, if this is done to local disk we are seeing the avg. of 4 seconds. The size of the module they are checking out is 4mb, this is what I have been doing tests with, but other cvs modules are also slow while being written to the nfs mount home directory. The filers also have the nfs.tcp.xfersize of 32k. Here are the configs of the filer: F760 NetApp Release 6.0.1R3: Fri Feb 16 02:42:49 PST 2001 e0: flags=8042<BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.174.32.67 netmask 0xffffff80 broadcast 10.174.32.127 ether 00:a0:98:00:56:a3 (auto-100tx-down) e4: flags=900042<BROADCAST,RUNNING,TCPCKSUM> mtu 1500 inet 10.174.32.126 netmask 0xffffff80 broadcast 10.174.32.127 ether 00:60:cf:20:31:fb (1000fx) e6: flags=848043<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.174.32.7 netmask 0xffffff80 broadcast 10.174.32.127 ether 00:90:27:f4:5b:0e (auto-1000sx-fd-up) flowcontrol full lo: flags=948049<UP,LOOPBACK,RUNNING,MULTICAST,TCPCKSUM> mtu 9188 inet 127.0.0.1 netmask 0xff000000 broadcast 127.0.0.1 We currently only use e6. nfs.mount_rootonly on nfs.per_client_stats.enable off nfs.tcp.enable on nfs.tcp.xfersize 32768 nfs.udp.xfersize 8192 nfs.v2.df_2gb_lim off nfs.v3.enable on nfs.webnfs.enable off nfs.webnfs.rootdir XXX nfs.webnfs.rootdir.set off I hope you all can help. cheers, edwardv-
