Troubleshooting High NFS OPS
by drew.odonnell＠americas.bnpparibas.com 10 Jun '03

10 Jun '03

We are experiencing high NFS ops, I am trying to find out who the high offenders are, however I am not sure if there is a better or more conclusive way. Basically: I am doing the following nfs.per_client_stats.enable on nfsstat -z nfsstat -h nfs.per_client_stats.enable off At the end of the mail I have attached a copy of the results of the nfsstat -h command (for 1 system). I just look for which systems have the highest percentage of reads and writes. My question is how do determine who the main users are based on the results of this command? Also is there a better way to do this? Are there other commands?

BUSINESS PROPOSAL
by KATURA BANGA 10 Jun '03

10 Jun '03

Dear Friend, Difficulties encountered in efforts to establish a business abroad necessitate this search for someone to assist me in securing and investing the sum of USD21,000.000 (twenty one million dollars)inherited from my father's business reserve. I am the heir of a Zimbabwean family; my father was an agriculturist. He became rich from his old-aged investment in agriculture and later was victimized by President Robert Mugabe's land reform policy. He was assassinated by unknown gunmen for defending his land ownership and siding the minority white farmers. Before his death, my father foresaw the insecurity of both our lives and property then decided to deposit the above sum with a private finance and security firm in Europe. This money has become the only inherited property of our family since our home was burnt,and the farmlands and machines seized; yet the government and it's loyalists are bent on making life difficult for us. To summarise this traumatic story, my mother and I have decided to offer 15% of the above sum to anyone who assists us to secure this funds overseas or 25% share for possible help on investing in any reliable venture. there are however some minimal cost involved in securing the release of this deposit from the present holding company.i do not intend to overburden you with these cost.but you must know beforehand that we will be sharing whatever cost involved in retrieving this deposit and putting it to beneficial use. if you would want to proceed under these terms,please reply for detailed information. if you do not accept my offer,please in good fate treat with utmost confidentiality . A quick reply with your name,telephone and fax numbers for more confidential communication will be highly appreciated. Sincerely yours, KATURA BANGA

NFS/snapshot activity log
by Brian Tao 10 Jun '03

10 Jun '03

What do people do to track NFS activity on their filers? Basically a real-time audit log on the filer showing NFS calls, file sizes, pathname info, uid, etc. I often run into situations where I can see a filer filling up very quickly (or the snapshot reserve doing the same thing), but no way of figuring who/what is doing it. I could sniff the network for NFS packets and decode them, but it seems the best place to look for this information is on the filer. It can probably make better sense of NFS streams than picking off individual packets. On a related note, are there any utilities available for more granular reporting on snapshot usage? Like being able to tell which file or directory or uid is occupying what percentage of the snapshot reserve? This wasn't possible a few years ago, but I figure the smart Netapp engineers would have thought of something since then. ;-) -- Brian Tao (BT300, taob(a)risc.org) "Though this be madness, yet there is method in't"

This gives NFS calls - anyone know anything that counts lock/unlock calls too?

You can use nfsstat like this: options nfs.per_client_stats.enable on nfsstat -z This causes the filer to accumulate per client nfs statistics and nfsstat -z zeroes all counters. Now let the filer run for a little while and run nfsstat -l This will give you a summary of total nfs ops by each client since the nfsstat -z. This will allow you to determine which clients are "hot". To see detailed counts for a particular client, use nfsstat -h hostname This will show if the client is doing any writes. You still won't know which files are being written, though. Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

venture proposition.
by solomonsavinbi＠tiscali.co.uk 09 Jun '03

Good day, I have to first of all apologise for taking unawares by the contents of this message. I had to send the message straightaway because of the short time involved in what I demand of you. Please treat this message with utmost seriousness and swiftness. Apart from the fact that you will be adequately rewarded, I will forever show my gratitude. I am Mr. Solomon Savimbi, son of the late Angolan Leader Jonas Savimbi who was killed last year. I got your contact details from the internet because I really have no time and I needed an anonymous person abroad whom I hope I can trust. I pray I am not making wrong judgement by coming to you. Jonas Savimbi deposited a large sum of money with a security vault in Europe and America that is my late father. The movement of members of his family (including me) is restricted. Our movement are monitored but I have managed to enter Italy where I intend to lie very low until I complete this transaction with you. Other members of my family and I do not have access to any of these deposits with banks in Angola,America and Europe so you can see how desperately we need your assistance. Both government officials and fraudulent relatives are trying to get their hands on my father's wealth by claiming that the wealth was gotten through arms smuggling and illegal sale of diamonds. You can find out more about my late father by checking this profile at URL below: http://www.rte.ie/news/2002/0223/angola.html http://www.rnw.nl/humanrights/html/vitoria1020814.html http://www.zzam.org/Full/Africa/Angola/History/Angola_History_Leaders. His wealth is estimated to be over US$1billion and my mother, being the only one with some of the documents has aided me to sneak into Italy refugee Camp and conclude this transaction with any one I choose. I have spoken with the security company and the operations manager has agreed to release the two trunk boxes in their possession to whomever's name I issue a power of attorney as the new beneficiary of the deposit. This security company has US$50,000,000.00 each and precious materials which my father lodged in their safe keep in Europe and U.S.A. before his death so I will give you their contact and relevant documents including power of attorney to allow you access to the two trunk boxes of money. The whole idea is for you to receive this money physically, set up bank accounts in U.S.A and Europe and transfer in bits into your home bank accounts before my government even knows what is happening. My father was a rebel leader in Angola before his death. You must follow my instructions as stated above the transfer of the funds because it will be difficult for the Angolan government to trace my father's money to an individuals account moreso, when you have no prior relationship with us. I am currently and temporarily living in Italy refugee camp and I will be communicating with you on a cell phone to avoid intervention by the authorities. We have to keep this transaction very secret because of the political situation in Angola at the moment. I shall send you a password and information that will include power of attorney and the contact of the security company as soon as you are ready to proceed. Could you please send your full names, address, confidential telephone and fax number to enable me issue a power of attorney to you and refer you to the security company in Atlanta/Amsterdam for immediate payment. Yours sincerely, Solomon Saimbi N:B. Reply to solosavimbi(a)netscape.net
