Save yourself from Gal Bladder (Kidney Stone)
by Citizen Welfare Organisation 01 Mar '05

Following is the article extracted from dawn (28/02/05) KARACHI: Reduction in tea urged to check stone formation - Urolithiasis symposium concludes KARACHI, Feb 27: Health experts at a symposium on Sunday recommended that tea and coffee should be reduced and dark-coloured soft drinks, aerated drinks and alcohol should be avoided to prevent formation of urinary stones. They were speaking at the concluding session of three-day urolithiasis symposium, organized by the Sindh Institute of Urology Transplant in association with the European Urolithiasis Society. During the panel discussion on "Are urinary stones preventable?" health professional said that excess oxalates in diet, less fluid intake particularly in hot climate, and warm working environment were common risk factors for stone formation in the urinary tract. Panellists of the session were Dr S.R. Khan from the USA, Dr A. Rodgers from S. Africa, Dr P.N. Rao from the United Kingdom, Dr A. Hesse from Germany, Dr K. Sarica from Turkey, Dr F. Marickar from India, Dr D. Gohel from Hong Kong, Dr N. Laube from Germany, Dr P. Shrivastav from India and Dr Adibul Hasan Rizvi. Dr A. Naqvi was the moderator. The joint consensus was that recurrence of stones in a person having had stone disease could be decreased. "General recommendations are that fluid intake should be sufficient to make the urine of a light colour. Plain water, barley water and rice water are beneficial. Yoghurt is also beneficial as it helps to disintegrate bacteria," they said. Earlier, describing the history of urinary tract stone disease, Dr F.A. Khan from Lahore stated that Andersen in 1932 had described southern Punjab as the hot spot for kidney stones. Reporting the results of a survey on bladder stone among children in Punjab, he said that the age at onset was as low as one year, while it was also observed that in Northern Punjab upper tract stones were higher in incidence, whereas in Southern Punjab bladder stones were more common. "Bladder stones in children are closely linked with poverty and diarrhoeal disease," he added. Dr M.D.I. Gohel from Hong Kong discussed whether kidney stones be eradicated by herbal medicines. He delivered an interesting talk on Chinese kampou medicine, being used to inhibit calcium oxalate crystallization. He said that experimental studies had proved that herbal medicines contained substances, which could prevent calcium oxalate aggregation and growth. This could prevent renal stone formation and help to expel the crystal easily, he added. Dr Fazil Marickar from India said that plant extracts, especially scoparia dulcis, had proved very successful in clearing renal injuries produced by oxalate crystals. "Substances as tamarind, plantain stem and horse gram help in passage, reduction of size and movement of stones," he added. Talking on ethnobotanic approaches towards treatment of stone disease, Dr I. Chaudhry said that it was conversion of a natural product into a useful substance. He predicted that in future food fossils would be consumed in larger quantities and research on them would help in using them as therapy for many diseases. Discussing the metabolic aspects of stone disease, Dr Shrivastav from India said that low urinary volume, low citrate and high uric acid levels in urine had been observed in significantly large number of patients with renal stones. "These factors could be taken as predictors for stone formation in the future," he added. -PPI This is a public welfare message and sent one time any ways if u want to unsubscribe then send an email with a subject remove to removemefromlist(a)gawab.com If you want to send your offer to 500,000 peoples then email at khimarketing(a)gawab.com

RE: Quick access to quota information
by barrie_spence＠agilent.com 28 Feb '05

28 Feb '05

I've just been busy writing a script to manage and enforce quotas the "UNIX way" (i.e. lock down the quota at the soft limit if the user doesn't cleanup within 14 days of exceeding it). The CPAN Perl "Quota" module works a treat: use Quota; $host='filer'; $volume_path = '/vol/vol1/users'; $uid = 501; ($block_curr, $block_soft, $block_hard, $block_timelimit, $inode_soft, $inode_hard, $inode_timelimit) = Quota::rpcquery($host, $volume_path, $uid); It's pretty fast and appears to work on HP-UX, Solaris and Linux. The only thing you have to watch for is that the results are low while the quotas are resizing (easy to check with a SNMP query).

The most convenient way would be short series of SNMP queries for specific UID / GID. Any suggestions other than "make and parse quota report" are welcome. Best regards, Jacek

full volume performance
by Charles Bartels 28 Feb '05

28 Feb '05

Hi Folks, It is pretty well know that disk performance start to suffer when the partition begins to fill up. So I am wondering if you would see the same effect with a full volume (traditional or flexible) in a relatively empty aggregate, or a full qtree in a relatively empty volume? Any thoughts on the matter would be appreciated. -C.

RE: F720 head upgrade?

You have some NFS tuning to do in TCP, UDP is fine. This isnt your root problem, but it cant help. Check the output regarding TCP receive buffer sizes. Client vancouver has network problems, NFS retransmits. Check output. Doesnt harm the system, but that client is impacted. Youre fighting performance -vs- storage space. You have a number of 18 and 36G drives. Vol0 is laid out properly given this mix, you dont mix sizes within a given raid group. However disks 16, 18, and 19 are on their own as the raid group of 36G drives for this volume. They are also being beat on pretty hard. I see that your cache hits are 100%, this would cause you to wonder if you need a larger filer, more cache RAM..but that might not be it. You have 100% disk utilization as a fact of life on the system, but you are only doing disk reads for the most part, and NOT heavy ones. Nine to 12Mb/sec max. Thats danged odd. Heres your problem. Vol0. The 18G drives are about 65% busy, 95% reads. The 36G drives are 83% bush, again mostly reads. Vol1 is quiet as a church on bowling night. Solutions: Move data being accessed from vol0 to vol1, make use of the untilized performance you have there if this 60 seconds of history is a normal data activity. Likewise, move some of that date from vol1 to vol0, because you never want over 80% full volumes. ;) Rebuild your volumes. Make vol0 all of the 18G drives, 11data-1parity. Raw about 204Mb. Make vol1 all of the 36G drives, 6data-1parity. Raw about 207Mb. If you did this, your volume sizes would be larger than they are today, because youre not wasting space on mixed sized raid groups of 18 and 36G drives (vol1 is like this), and you end up with a LARGER number of spindles to parellelize your data access across in vol0 with a single volume of more 18G drives. Guaranteed, 100% of your performance problem is that itty bitty second raid group in volume 1. Unfortunately you will have to destroy the village to save it, but once you take the downtime to do so, you might find years of worthwhile performance out of your 720. Of course, you get to play God at work, and save a ton of cash while making thing better with no money spent. Yes, a larger system might reduce the missed cache hits, but 12Mb/sec is WAY less than a properly configured F720 can dish out. Id say you could triple that output easy if you did this. Is a 12drive raid group ok?? Id say YES. ONTAP is wayyyy more resilient than it used to be. You have plenty of drives left if you like, to enable raid_dp as well, which will give a 10data-2parity the basic reliability of two separate 5-1 raid groups, cept you have a larger stripe to make your reads against which seems to be your largest type of data activity according to this perfstat. What size Tshirt do I wear? XXL. :)

EOGI's high-yie|ding, mu|tip|e dri|ling programs have been solidified through valuab|e strategic al|iances. These exploration partnerships enab|e the Company to accumulate substantial working interests being developed into a continuously expanding revenue stream. EOGI is focused on joint-ventures involving we|l re-entry programs in extremely pro|ific production areas using the highest |eve| of techno|ogy currently available. Recent deve|opments for EOGI have been perfectly timed as a|| 6 Dow Jones Oi| and Gas Indexes just hit their highest |evels of the year, with Energy Stocks outperforming a|l other market sectors. The Company's Oi| and Gas interests in Louisiana and Texas, in addition to their deve|oping natural gas wel|s in Alberta, Canada, are continuing to in crease in va|ue with energy prices up 60% from one year ago.

Run a perfstat..or at least tell us what its been up to. Has the file system been full or over 80% for any period of time? A perfstat will shed a TON of light.

Spare Drive Assignment
by Jeff Mohler 27 Feb '05

27 Feb '05

My customer had to replace a drive, and they asked if a filer can be told (non clustered system) to automagically assign a new drive to the only head in the system? Just seems odd to have to tell the system the ownership of a drive, with only one head in the mix.

Ohh..those shelves. I -think- theyre FC7s and FC8s. Should work with any head thru the 800 series of filers, I dont recall the official answer on using those with 900s.
