• stored as array understanding mongoid

  - by Gagan

  Hello frens, This is not a problem, but I just want to know stored as array of Mongoid better. I have following code in my model. class Company include Mongoid::Document include Mongoid::Timestamps references_many :people, :stored_as => :array, :inverse_of => :companies end class Person include Mongoid::Document include Sunspot::Mongoid references_many :companies, :stored_as => :array, :inverse_of => :people end Now in Company object we get person_ids as a result of stored_as array and company_ids in Person object. Now initially I inserted lots of person in company and the ids in person_ids fields is huge. Now I deleted most of person from company down to 8 people. Now I don't get why person_ids fields of Company object storing all the deleted ids of person. My console snapshot is follwing ruby-1.9.2-head Company.first.person_ids = [BSON::ObjectId('4d12d2907adf350695000025'), BSON::ObjectId('4d12d2907adf35069500002c'), BSON::ObjectId('4d12d2907adf350695000035'), BSON::ObjectId('4d12d2907adf35069500003f'), BSON::ObjectId('4d12d2907adf350695000048'), BSON::ObjectId('4d12d2907adf350695000052'), BSON::ObjectId('4d12d2907adf350695000059'), BSON::ObjectId('4d12d2907adf350695000062'), BSON::ObjectId('4d12d4017adf35069500008d'), BSON::ObjectId('4d12d4017adf350695000094'), BSON::ObjectId('4d12d4017adf35069500009d'), BSON::ObjectId('4d12d4017adf3506950000a7'), BSON::ObjectId('4d12d4017adf3506950000b0'), BSON::ObjectId('4d12d4017adf3506950000ba'), BSON::ObjectId('4d12d4017adf3506950000c1'), BSON::ObjectId('4d12d4017adf3506950000ca'), BSON::ObjectId('4d12d48a7adf3506950000f5'), BSON::ObjectId('4d12d48a7adf3506950000fc'), BSON::ObjectId('4d12d48a7adf350695000108'), BSON::ObjectId('4d12d48b7adf350695000115'), BSON::ObjectId('4d12d48b7adf350695000121'), BSON::ObjectId('4d12d48b7adf35069500012e'), BSON::ObjectId('4d12d48b7adf350695000135'), BSON::ObjectId('4d12d48b7adf350695000141'), BSON::ObjectId('4d12d53e7adf35069500016f'), BSON::ObjectId('4d12d53e7adf350695000176'), BSON::ObjectId('4d12d53e7adf350695000182'), BSON::ObjectId('4d12d53e7adf35069500018f'), BSON::ObjectId('4d12d53e7adf35069500019b'), BSON::ObjectId('4d12d53f7adf3506950001a8'), BSON::ObjectId('4d12d53f7adf3506950001af'), BSON::ObjectId('4d12d53f7adf3506950001bb'), BSON::ObjectId('4d12d8587adf3506950001e9'), BSON::ObjectId('4d12d8587adf3506950001f0'), BSON::ObjectId('4d12d8587adf3506950001ff'), BSON::ObjectId('4d12d8597adf35069500020f'), BSON::ObjectId('4d12d8597adf35069500021e'), BSON::ObjectId('4d12d8597adf35069500022e'), BSON::ObjectId('4d12d8597adf350695000235'), BSON::ObjectId('4d12d85a7adf350695000244'), BSON::ObjectId('4d12d9587adf35069500025b'), BSON::ObjectId('4d12db8b7adf35069500026a'), BSON::ObjectId('4d12de6f7adf3509c9000024'), BSON::ObjectId('4d12de6f7adf3509c900002b'), BSON::ObjectId('4d12de6f7adf3509c900003a'), BSON::ObjectId('4d12de707adf3509c900004a'), BSON::ObjectId('4d12de707adf3509c9000059'), BSON::ObjectId('4d12de707adf3509c9000069'), BSON::ObjectId('4d12de707adf3509c9000070'), BSON::ObjectId('4d12de717adf3509c900007f'), BSON::ObjectId('4d12e7f27adf350bd2000009'), BSON::ObjectId('4d12e81f7adf350bd2000015'), BSON::ObjectId('4d12e87f7adf350bd2000024'), BSON::ObjectId('4d12e8b87adf350bd200004c'), BSON::ObjectId('4d12e8b97adf350bd2000053'), BSON::ObjectId('4d12e8b97adf350bd200005c'), BSON::ObjectId('4d12e8b97adf350bd2000066'), BSON::ObjectId('4d12e8b97adf350bd200006f'), BSON::ObjectId('4d12e8b97adf350bd2000079'), BSON::ObjectId('4d12e8ba7adf350bd2000080'), BSON::ObjectId('4d12e8ba7adf350bd2000089'), BSON::ObjectId('4d12ee6b7adf350bd2000198'), BSON::ObjectId('4d12ee6b7adf350bd200019f'), BSON::ObjectId('4d12ee6c7adf350bd20001a5'), BSON::ObjectId('4d12ee6c7adf350bd20001ac'), BSON::ObjectId('4d12ee6c7adf350bd20001b2'), BSON::ObjectId('4d12ee6c7adf350bd20001b9'), BSON::ObjectId('4d12ee6c7adf350bd20001c0'), BSON::ObjectId('4d12ee6c7adf350bd20001c6'), BSON::ObjectId('4d141ca57adf35033e00006e'), BSON::ObjectId('4d141ca57adf35033e000075'), BSON::ObjectId('4d1420aa7adf350705000003'), BSON::ObjectId('4d1420aa7adf35070500000a'), BSON::ObjectId('4d1420f47adf350705000011'), BSON::ObjectId('4d1420f57adf350705000015'), BSON::ObjectId('4d1420f57adf350705000018'), BSON::ObjectId('4d1420f57adf35070500001c'), BSON::ObjectId('4d1420f57adf350705000023'), BSON::ObjectId('4d1420f57adf350705000026'), BSON::ObjectId('4d14215f7adf35070500004b'), BSON::ObjectId('4d14215f7adf350705000052'), BSON::ObjectId('4d14215f7adf350705000055'), BSON::ObjectId('4d14215f7adf350705000059'), BSON::ObjectId('4d14215f7adf35070500005c'), BSON::ObjectId('4d14215f7adf350705000060'), BSON::ObjectId('4d14215f7adf350705000067'), BSON::ObjectId('4d14215f7adf35070500006a')] Company.first.people.collect(&:id) = [BSON::ObjectId('4d14215f7adf35070500004b'), BSON::ObjectId('4d14215f7adf350705000052'), BSON::ObjectId('4d14215f7adf350705000055'), BSON::ObjectId('4d14215f7adf350705000059'), BSON::ObjectId('4d14215f7adf35070500005c'), BSON::ObjectId('4d14215f7adf350705000060'), BSON::ObjectId('4d14215f7adf350705000067'), BSON::ObjectId('4d14215f7adf35070500006a')] Isn't the Company.first.person_ids array be only storing the ids shown by Company.first.people.collect(&:id) It would be helpful if some one tell me when to best use stored_as = :array method. Do stored_as = :array increase querying performance? Thanks

• PHP Session Class and $_SESSION Array

  - by Gianluca Bargelli

  Hello, i've implemented this custom PHP Session Class for storing sessions into a MySQL database: class Session { private $_session; public $maxTime; private $database; public function __construct(mysqli $database) { $this->database=$database; $this->maxTime['access'] = time(); $this->maxTime['gc'] = get_cfg_var('session.gc_maxlifetime'); session_set_save_handler(array($this,'_open'), array($this,'_close'), array($this,'_read'), array($this,'_write'), array($this,'_destroy'), array($this,'_clean') ); register_shutdown_function('session_write_close'); session_start();//SESSION START } public function _open() { return true; } public function _close() { $this->_clean($this->maxTime['gc']); } public function _read($id) { $getData= $this->database->prepare("SELECT data FROM Sessions AS Session WHERE Session.id = ?"); $getData->bind_param('s',$id); $getData->execute(); $allData= $getData->fetch(); $totalData = count($allData); $hasData=(bool) $totalData >=1; return $hasData ? $allData['data'] : ''; } public function _write($id, $data) { $getData = $this->database->prepare("REPLACE INTO Sessions VALUES (?, ?, ?)"); $getData->bind_param('sss', $id, $this->maxTime['access'], $data); return $getData->execute(); } public function _destroy($id) { $getData=$this->database->prepare("DELETE FROM Sessions WHERE id = ?"); $getData->bind_param('S', $id); return $getData->execute(); } public function _clean($max) { $old=($this->maxTime['access'] - $max); $getData = $this->database->prepare("DELETE FROM Sessions WHERE access < ?"); $getData->bind_param('s', $old); return $getData->execute(); } } It works well but i don't really know how to properly access the $_SESSION array: For example: $db=new DBClass();//This is a custom database class $session=new Session($db->getConnection()); if (isset($_SESSION['user'])) { echo($_SESSION['user']);//THIS IS NEVER EXECUTED! } else { $_SESSION['user']="test"; Echo("Session created!"); } At every page refresh it seems that $_SESSION['user'] is somehow "resetted", what methods can i apply to prevent such behaviour?

• How to loop an array with strings as indexes in PHP

  - by Axel Lambregts

  I had to make an array with as indexes A-Z (the alphabet). Each index had to have a value 0. So i made this array: $alfabet = array( 'A' => 0, 'B' => 0, 'C' => 0, 'D' => 0, 'E' => 0, 'F' => 0, 'G' => 0, 'H' => 0, 'I' => 0, 'J' => 0, 'K' => 0, 'L' => 0, 'M' => 0, 'N' => 0, 'O' => 0, 'P' => 0, 'Q' => 0, 'R' => 0, 'S' => 0, 'T' => 0, 'U' => 0, 'V' => 0, 'W' => 0, 'X' => 0, 'Y' => 0, 'Z' => 0 ); I also have got text from a file ($text = file_get_contents('tekst15.txt');) I have putted the chars in that file to an array: $textChars = str_split ($text); and sorted it from A-Z: sort($textChars); What i want is that (with a for loop) when he finds an A in the textChars array, the value of the other array with index A, goes up by one (so like: $alfabet[A]++; Can anyone help me with this loop? I have this atm: for($i = 0; $i <= count($textChars); $i++){ while($textChars[$i] == $alfabet[A]){ $alfabet[A]++; } } echo $alfabet[A]; Problem 1: i want to loop the alfabet array to, so now i only check for A but i want to check all indexes. Problem2: this now returns 7 for each alphabet index i try so its totally wrong :) I'm sorry about my english but thanks for your time.

• Sort array by two specifics values in PHP

  - by Roger

  The folks have already showed me how to sort an array by a specific value using usort and a fallback function in PHP. What if this specifc value doesn't exist and we have to use two values? in the example bellow the values [4] and [5]... In other words, I want to do this: order all objects numericaly by the fith value of each object from the highest to the lowest, and addicionally, for those objects that have the fifht value is empty (in the examplem '-'), order them by the fourth value. Array( [0] => Array( [0] => links-patrocinados [1] => adwords [2] => 0,5 [3] => R$92,34 [4] => 823000 [5] => 49500 ) [1] => Array( [0] => adwords [1] => google adwords como funciona [2] => 0,38 [3] => R$0,20 [4] => 480 [5] => 480 ) [2] => Array( [0] => links-patrocinados [1] => adword [2] => 0,39 [3] => R$58,77 [4] => 49500 [5] => 2900 ) [3] => Array( [0] => agencia [1] => agencias viagens espanholas [2] => - [3] => R$0,20 [4] => 58 [5] => - ) [4] => Array( [0] => agencia [1] => era agencia imobiliaria [2] => - [3] => R$0,20 [4] => 73 [5] => - ) )

• C# Type Casting at Runtimefor Array.SetValue

  - by sprocketonline

  I'm trying to create an array using reflection, and insert values into it. I'm trying to do this for many different types so would like a createAndFillArray function capable of this : Type t1 = typeof(A); Type t2 = typeof(B); double exampleA = 22.5; int exampleB = 43; Array arrA = createAndFillArray(t1, exampleA); Array arrB = createAndFillArray(t2, exampleB); private Array createAndFillArray(Type t, object val){ Array arr = Array.CreateInstance( t, 1); //length 1 in this example only, real-world is of variable length. arr.SetValue( val, 0 ); //this causes the following error: "System.InvalidCastException : Object cannot be stored in an array of this type." return arr; } with the class A being as follows: public class A{ public A(){} private double val; public double Value{ get{ return val; } set{ this.val = value; } } public static implicit operator A(double d){ A a = new A(); a.Value = d; return a; } } and class B being very similar, but with int: public class B{ public B(){} private double val; public double Value{ get{ return val; } set{ this.val = value; } } public static implicit operator B(double d){ B b = new B(); b.Value = d; return b; } } I hoped that the implicit operator would have ensured that the double be converted to class A, or the int to class B, and the error avoided; but this is obviously not so. The above is used in a custom deserialization class, which takes data from a custom data format and fills in the corresponding .Net object properties. I'm doing this via reflection and at runtime, so I think both are unavoidable. I'm targeting the C# 2.0 framework. I've dozens, if not hundreds, of classes similar to A and B, so would prefer to find a solution which improved on the createAndFillArray method rather than a solution which altered these classes.

• Dirty Cache Dell Equallogic Storage Array

  - by Jermal Smith

  has anyone ever run into a dirty cache issue with a Equallogic SAN. Even after replacement of the controller cards in the Equallogic Storage Array fails offline with a dirty cache. I have listed steps here on my blog to bring the SAN online again, however this is not the best solution as it continues to fail. http://jermsmit.com/dirty-cache-dell-equallogic-storage-array/ If you have any info on this please share.

• Mysteriously empty $_POST array

  - by Lex

  Hi all! I have the following HTML/PHP page: <?php if(empty($_SERVER['CONTENT_TYPE'])) { $type = "application/x-www-form-urlencoded"; $_SERVER['CONTENT_TYPE'] = $type; } echo "<pre>"; var_dump($_POST); var_dump(file_get_contents("php://input")); echo "</pre>"; ?> <form method="post" action="test.php"> <input type="text" name="test[1]" /> <input type="text" name="test[2]" /> <input type="text" name="test[3]" /> <input type="submit" name="action" value="Go" /> </form> As you can see, the form will submit and the expected output is a POST array with one array in it containing the filled in values and one entry "action" with the value "Go" (the button). However, no matter what values I enter in the fields; the result is always: array(2) { ["test"]=> string(0) "" ["action"]=> string(2) "Go" } string(16) "test=&action=Go&" Somehow, the array named test is emptied, the "action" variable does make it through. I've used the Live HTTP Headers extension for Firefox to check whether the POST fields get submitted, and they do. The relevant information from Live HTTP Headers (with a, b and c filled in as values in the textboxes): Content-Type: application/x-www-form-urlencoded Content-Length: 51 test%5B1%5D=a&test%5B2%5D=b&test%5B3%5D=c&action=Go Does anybody have any idea as to why this is happening? I'm freaking out on this one, it has cost me so much time already... EDIT: We've tried this on different servers, on Windows boxes it does work, on the Ubuntu server with PHP version 5.2.4 (with Suhosin), it doesn't. It even works on a different server, also with Ubuntu and the same PHP version, also with Suhosin installed.

• Server restarted while rebuilding array, what to do?

  - by user239054

  It's a HP ProLiant DL380 Generation 7, that has four hard drives, one is dead, I suppose that another one is dead too, but is there any way to force the array to rebuild again? The server has restarted while it was rebuilding an array. My windows server(2008) that is on it won't boot, it goes directly to system recovery screen. I have an image backup, would restoring it be my only option?If I restore, it will get back to regular automatically or will I have to configure something?

• HP Smart Array p400i with Intel X25-M 160 SSD

  - by user67304

  I have a pair of x25-M 160 Intel SSD's in an HP DL360 G5 with a p400i Smart Array running 512 BBWC. The disk performance I am getting on this box and another identical one does not come close to matching the same two drives running through a cheap 3ware RAID card. Any idea? I have played with the cache settings, but nothing allows me to get the same results. It seems like the Smart Array controller is the bottleneck.

• convert full-disk RAID5 array to partition-based array?

  - by Delan Azabani

  I have a RAID 5 array, md0, with three full-disk (non-partitioned) members, sdb, sdc, and sdd. My computer will hang during the AHCI BIOS if AHCI is enabled instead of IDE, if these drives are plugged in. I believe it may be because I'm using the whole disk, and the AHCI BIOS expects an MBR to be on the drive (I don't know why it would care). Is there a way to convert the array to use members sdb1, sdc1 and sdd1, partitioned MBR with 0xFD RAID partitions?

• Recover RAID 5 data after created new array instead of re-using

  - by Brigadieren

  Folks please help - I am a newb with a major headache at hand (perfect storm situation). I have a 3 1tb hdd on my ubuntu 11.04 configured as software raid 5. The data had been copied weekly onto another separate off the computer hard drive until that completely failed and was thrown away. A few days back we had a power outage and after rebooting my box wouldn't mount the raid. In my infinite wisdom I entered mdadm --create -f... command instead of mdadm --assemble and didn't notice the travesty that I had done until after. It started the array degraded and proceeded with building and syncing it which took ~10 hours. After I was back I saw that that the array is successfully up and running but the raid is not I mean the individual drives are partitioned (partition type f8 ) but the md0 device is not. Realizing in horror what I have done I am trying to find some solutions. I just pray that --create didn't overwrite entire content of the hard driver. Could someone PLEASE help me out with this - the data that's on the drive is very important and unique ~10 years of photos, docs, etc. Is it possible that by specifying the participating hard drives in wrong order can make mdadm overwrite them? when I do mdadm --examine --scan I get something like ARRAY /dev/md/0 metadata=1.2 UUID=f1b4084a:720b5712:6d03b9e9:43afe51b name=<hostname>:0 Interestingly enough name used to be 'raid' and not the host hame with :0 appended.

• Search multiple datepicker on same grid

  - by DHF

  I'm using multiple datepicker on same grid and I face the problem to get a proper result. I used 3 datepicker in 1 grid. Only the first datepicker (Order Date)is able to output proper result while the other 2 datepicker (Start Date & End Date) are not able to generate proper result. There is no problem with the query, so could you find out what's going on here? Thanks in advance! php wrapper <?php ob_start(); require_once 'config.php'; // include the jqGrid Class require_once "php/jqGrid.php"; // include the PDO driver class require_once "php/jqGridPdo.php"; // include the datepicker require_once "php/jqCalendar.php"; // Connection to the server $conn = new PDO(DB_DSN,DB_USER,DB_PASSWORD); // Tell the db that we use utf-8 $conn->query("SET NAMES utf8"); // Create the jqGrid instance $grid = new jqGridRender($conn); // Write the SQL Query $grid->SelectCommand = "SELECT c.CompanyID, c.CompanyCode, c.CompanyName, c.Area, o.OrderCode, o.Date, m.maID ,m.System, m.Status, m.StartDate, m.EndDate, m.Type FROM company c, orders o, maintenance_agreement m WHERE c.CompanyID = o.CompanyID AND o.OrderID = m.OrderID "; // Set the table to where you update the data $grid->table = 'maintenance_agreement'; // set the ouput format to json $grid->dataType = 'json'; // Let the grid create the model $grid->setPrimaryKeyId('maID'); // Let the grid create the model $grid->setColModel(); // Set the url from where we obtain the data $grid->setUrl('grouping_ma_details.php'); // Set grid caption using the option caption $grid->setGridOptions(array( "sortable"=>true, "rownumbers"=>true, "caption"=>"Group by Maintenance Agreement", "rowNum"=>20, "height"=>'auto', "width"=>1300, "sortname"=>"maID", "hoverrows"=>true, "rowList"=>array(10,20,50), "footerrow"=>false, "userDataOnFooter"=>false, "grouping"=>true, "groupingView"=>array( "groupField" => array('CompanyName'), "groupColumnShow" => array(true), //show or hide area column "groupText" =>array('<b> Company Name: {0}</b>',), "groupDataSorted" => true, "groupSummary" => array(true) ) )); if(isset($_SESSION['login_admin'])) { $grid->addCol(array( "name"=>"Action", "formatter"=>"actions", "editable"=>false, "sortable"=>false, "resizable"=>false, "fixed"=>true, "width"=>60, "formatoptions"=>array("keys"=>true), "search"=>false ), "first"); } // Change some property of the field(s) $grid->setColProperty("CompanyID", array("label"=>"ID","hidden"=>true,"width"=>30,"editable"=>false,"editoptions"=>array("readonly"=>"readonly"))); $grid->setColProperty("CompanyName", array("label"=>"Company Name","hidden"=>true,"editable"=>false,"width"=>150,"align"=>"center","fixed"=>true)); $grid->setColProperty("CompanyCode", array("label"=>"Company Code","hidden"=>true,"width"=>50,"align"=>"center")); $grid->setColProperty("OrderCode", array("label"=>"Order Code","width"=>110,"editable"=>false,"align"=>"center","fixed"=>true)); $grid->setColProperty("maID", array("hidden"=>true)); $grid->setColProperty("System", array("width"=>150,"fixed"=>true,"align"=>"center")); $grid->setColProperty("Type", array("width"=>280,"fixed"=>true)); $grid->setColProperty("Status", array("width"=>70,"align"=>"center","edittype"=>"select","editoptions"=>array("value"=>"Yes:Yes;No:No"),"fixed"=>true)); $grid->setSelect('System', "SELECT DISTINCT System, System AS System FROM master_ma_system ORDER BY System", false, true, true, array(""=>"All")); $grid->setSelect('Type', "SELECT DISTINCT Type, Type AS Type FROM master_ma_type ORDER BY Type", false, true, true, array(""=>"All")); $grid->setColProperty("StartDate", array("label"=>"Start Date","width"=>120,"align"=>"center","fixed"=>true, "formatter"=>"date", "formatoptions"=>array("srcformat"=>"Y-m-d H:i:s","newformat"=>"d M Y") )); // this is only in this case since the orderdate is set as date time $grid->setUserTime("d M Y"); $grid->setUserDate("d M Y"); $grid->setDatepicker("StartDate",array("buttonOnly"=>false)); $grid->datearray = array('StartDate'); $grid->setColProperty("EndDate", array("label"=>"End Date","width"=>120,"align"=>"center","fixed"=>true, "formatter"=>"date", "formatoptions"=>array("srcformat"=>"Y-m-d H:i:s","newformat"=>"d M Y") )); // this is only in this case since the orderdate is set as date time $grid->setUserTime("d M Y"); $grid->setUserDate("d M Y"); $grid->setDatepicker("EndDate",array("buttonOnly"=>false)); $grid->datearray = array('EndDate'); $grid->setColProperty("Date", array("label"=>"Order Date","width"=>100,"editable"=>false,"align"=>"center","fixed"=>true, "formatter"=>"date", "formatoptions"=>array("srcformat"=>"Y-m-d H:i:s","newformat"=>"d M Y") )); // this is only in this case since the orderdate is set as date time $grid->setUserTime("d M Y"); $grid->setUserDate("d M Y"); $grid->setDatepicker("Date",array("buttonOnly"=>false)); $grid->datearray = array('Date'); // This command is executed after edit $maID = jqGridUtils::GetParam('maID'); $Status = jqGridUtils::GetParam('Status'); $StartDate = jqGridUtils::GetParam('StartDate'); $EndDate = jqGridUtils::GetParam('EndDate'); $Type = jqGridUtils::GetParam('Type'); // This command is executed immediatley after edit occur. $grid->setAfterCrudAction('edit', "UPDATE maintenance_agreement SET m.Status=?, m.StartDate=?, m.EndDate=?, m.Type=?

• Drupal: Exposing a module's data to Views2 using its API

  - by Sepehr Lajevardi

  I'm forking the filefield_stats module to provide it with the ability of exposing data into the Views module via the API. The filefield_stats module db table schema is as follow: <?php function filefield_stats_schema() { $schema['filefield_stats'] = array( 'fields' => array( 'fid' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'Primary Key: the {files}.fid'), 'vid' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'Primary Key: the {node}.vid'), 'uid' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'The {users}.uid of the downloader'), 'timestamp' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE, 'description' => 'The timestamp of the download'), 'hostname' => array('type' => 'varchar', 'length' => 128, 'not null' => TRUE, 'default' => '', 'description' => 'The hostname downloading the file (usually IP)'), 'referer' => array('type' => 'text', 'not null' => FALSE, 'description' => 'Referer for the download'), ), 'indexes' => array('fid_vid' => array('fid', 'vid')), ); return $schema; } ?> Well, so I implemented the hook_views_api() in filefield_stats.module & added a filefield_stats.views.inc file in the module's root directory, here it is: <?php // $Id$ /** * @file * Provide the ability of exposing data to Views2, for filefield_stats module. */ function filefield_stats_views_data() { $data = array(); $data['filefield_stats']['table']['group'] = t('FilefieldStats'); // Referencing the {node_revisions} table. $data['filefield_stats']['table']['join'] = array( 'node_revisions' => array( 'left_field' => 'vid', 'field' => 'vid', ), /*'files' => array( 'left_field' => 'fid', 'field' => 'fid', ), 'users' => array( 'left_field' => 'uid', 'field' => 'uid', ),*/ ); // Introducing filefield_stats table fields to Views2. // vid: The node's revision ID which wrapped the downloaded file $data['filefield_stats']['vid'] = array( 'title' => t('Node revision ID'), 'help' => t('The node\'s revision ID which wrapped the downloaded file'), 'relationship' => array( 'base' => 'node_revisions', 'field' => 'vid', 'handler' => 'views_handler_relationship', 'label' => t('Node Revision Reference.'), ), ); // uid: The ID of the user who downloaded the file. $data['filefield_stats']['uid'] = array( 'title' => t('User ID'), 'help' => t('The ID of the user who downloaded the file.'), 'relationship' => array( 'base' => 'users', 'field' => 'uid', 'handler' => 'views_handler_relationship', 'label' => t('User Reference.'), ), ); // fid: The ID of the downloaded file. $data['filefield_stats']['fid'] = array( 'title' => t('File ID'), 'help' => t('The ID of the downloaded file.'), 'relationship' => array( 'base' => 'files', 'field' => 'fid', 'handler' => 'views_handler_relationship', 'label' => t('File Reference.'), ), ); // hostname: The hostname which the file has been downloaded from. $data['filefield_stats']['hostname'] = array( 'title' => t('The Hostname'), 'help' => t('The hostname which the file has been downloaded from.'), 'field' => array( 'handler' => 'views_handler_field', 'click sortable' => TRUE, ), 'sort' => array( 'handler' => 'views_handler_sort', ), 'filter' => array( 'handler' => 'views_handler_filter_string', ), 'argument' => array( 'handler' => 'views_handler_argument_string', ), ); // referer: The referer address which the file download link has been triggered from. $data['filefield_stats']['referer'] = array( 'title' => t('The Referer'), 'help' => t('The referer which the file download link has been triggered from.'), 'field' => array( 'handler' => 'views_handler_field', 'click sortable' => TRUE, ), 'sort' => array( 'handler' => 'views_handler_sort', ), 'filter' => array( 'handler' => 'views_handler_filter_string', ), 'argument' => array( 'handler' => 'views_handler_argument_string', ), ); // timestamp: The time of the download. $data['filefield_stats']['timestamp'] = array( 'title' => t('Download Time'), 'help' => t('The time of the download.'), 'field' => array( 'handler' => 'views_handler_field_date', 'click sortable' => TRUE, ), 'sort' => array( 'handler' => 'views_handler_sort_date', ), 'filter' => array( 'handler' => 'views_handler_filter_date', ), ); return $data; } // filefield_stats_views_data() ?> According to the Views2 documentations this should work as a minimum, I think. But it doesn't! Also there is no error of any kind, when I come through the views UI, there's nothing about filefield_stats data. Any idea?

• [Ubuntu 10.04] mdadm - Can't get RAID5 Array To Start

  - by Matthew Hodgkins

  Hello, after a power failure my RAID array refuses to start. When I boot I have to sudo mdadm --assemble --force /dev/md0 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1 /dev/sdg1 to get mdadm to notice the array.

• Move an existing RAID 5 array from Ubuntu to Gentoo

  - by Cocoabean

  I have a 64-bit Ubuntu machine with a 4-disk RAID 5 using software raid (md). I've been able to boot an Ubuntu LiveCD and recognize the array with a simple mdadm -A /dev/md0. It was easy to mount after that and nothing had to rebuild. I'm installing Gentoo on this box now (multi-boot, non-RAID root partition) and I have md auto-detect turned on in the kernel. When I boot Gentoo I get: "invalid superblock magic on sdd" for each of the drives in the array. I boot back to Ubuntu and they mount no problem. I tried copying the mdadm.conf that works in Ubuntu to Gentoo, and then ran mdadm -A /dev/md0 but it reports that there is no array named md0. I don't want to lose data (obviously) and I don't want to have to let the RAID rebuild every time I switch between OSes. Any help is appreciated. Both are using mdadm 3.1.4 Both are running 64-bit kernels. mdadm -D /dev/md0 from Ubuntu yields: http://pastebin.com/5gj2QNkV UPDATE: After rebooting I noticed that it still complains about invalid blocks, but cat /proc/mdstat shows an inactive /dev/md127 with the same disks as my raid. I want to mount it but I don't want to get stuck waiting for a rebuild or destroying it inadvertently. mdadm -D /dev/md127 Here is pastebin of mdadm -D /dev/md127 on gentoo: http://pastebin.com/gDCWn0Rn UPDATE II: dmesg output about 'invalid raid superblocks' http://paste.ubuntu.com/885471/ fdisk -l from Ubuntu, /dev/md0 does not have any partitions but I do have it mounted and accessible: http://paste.ubuntu.com/885475/

• Can one build a single disk RAID 1 array?

  - by Core Xii

  I have an Nvidia hardware RAID 1 array and need to reformat. But I don't have any spare storage media, so I need to get along with the 2 disks in the array. I figured I'd do as follows: Delete the array, so I have 2 separate but identical disks, A and B, with my files Put disk B aside Reformat disk A, build RAID 1 array with it, install Windows XP Put disk B back in Boot to Windows on disk A, copy my files from disk B to disk A Add disk B to the RAID 1 array, rebuild array And now I'd have a new RAID 1 array, fresh install and all my files intact (the ones I copied). Here are the parts I'm unsure about: Can I build a RAID 1 array using just one disk, then add the other one later? Can Windows on disk A see disk B and allow me to copy my files over?

• Move OS from RAID5 array to RAID 1 arrays

  - by Antoine

  I want to give a last boost to my old ProLiant ML350 G5 server which just needs to be reliable for a few more year only ! With a defined budget of about 1500$ (I do not have more), i plan to replace the CPU (+ adding a second one), the battery cache of my raid controller (E200i), double the RAM, and change all hard drives. I have 7 HDD (SAS 10krpm, 72Gb) + 1 spare in RAID5, and my system is all FULL (no empty tray, full disks). in my current RAID5 array, I have 2 partitions: - 1 OS partition, 20Gb - 1 data partition, 350 Gb I plan to replace these 8 disks with : - 2 x 300Gb SAS 15krpm in RAID 1 (= 1 partition for OS) - 2 x 2Tb SATA 7.2krpm in RAID 1 (= 1 partition for DATA) My biggest constraint is that I have only 01 day to upgrade my server. Therefore, I'm looking for cloning all my files (OS + data partition) to my new arrays, i.e : - the OS partition shall be cloned to the RAID1 "2x300Gb array" - the data partition shall be cloned to the RAID1 "2x2Tb array" My second problem is that I need to physically remove all the old hard drives before inserting the new ones. I'm running Windows Server 2003 R2, and even if MS support will expire soon, I cannot buy a new licence and spent time in configuration. Obviously, with 1500$, I cannot also buy a new server that I could start configuring from now ! Thought about ASR (NTBackup), but I have no floppy drive (and do not really want to invest in one !) Thought about a clonezilla clone, and read this interesting link : Windows Server 2003 - move C: partition to a new SAS disk , but i'm not so confident in using Clonezilla with RAID5. What should be the best option to quickly and easily (if possible!) "copy/paste" my OS (so no need to reinstall and reconfigure all) and DATA / programs / services, etc... ? Thanks for your comments

• mdadm: Replacing array with entirely new drives

  - by hellfur

  I have a server with three 500GB drives, with most of my data in a RAID5 configuration spanning the three of them. I just purchased and installed four 1TB drives, and the intention is to move off of the old drives and onto the new ones. I have enough SATA ports and power connectors to power all seven of my drives at once, so I've kept the old RAID running while I figure out what to do with the new drives. My question is: Should I create a whole new array on the 1TB drives, then move everything over and reconfigure linux to boot from the new md arrays? Or should I just expand the array, swapping out each of the three 500GBs with the 1TB, then adding the final drive? I've read up on the mdadm extending drive setup, and it makes sense, but I imagine I would use one of the drives as a full backup while I move things over, then add that drive back into the array once things are up and running on three of the 1TB drives, so there's some complication in going that route as well... I'm just not sure which is safer/recommended.
