  • JQUERY Ajax form, page refreshs & isn't supposed to in Safari, doesn't refresh in FF (works fine)

    - by nobosh
    I'm working on a AJAX form which lives in a JQUERY UI Dialog. It works great in FireFox, but for some reason, in safari it refreshes the page to: /? Please let me know if somethings wrong here? Thanks <div class="modal-container"> <form onsubmit="" action="" id="list-dialog-form" name="list-dialog-form"> <div id="modal-wrapper"> <br><br> <div class="modal-inputbar"> <span style="width: 100px;" class="inputbar-label"> <label>Edit List Name:</label> </span> <span style="width: 200px;" class="inputbar-input"> <input type="text" style="padding-right: 25px;" autocomplete="off" maxlength="140" id="listname" value="Untitled"> </span> </div> </div> <div id="modal-submit" class="modal-submit"> <span class="left delete-wrap"> <span onclick="deleteThisList(15);" class="delete"> </span> </span> <span style="line-height: 2em;" class="right"> <input type="hidden" value="15" id="tasklistID"> <input type="submit" value="update" id="dialogcloser"> <input type="button" onclick="$('#listeditdialog').dialog('close');" value="close" id="dialogcloser"> </span> </div> </form> </div> // Handles Updating the List Title $("#list-dialog-form").submit(function(){ // Ajax Spinner $("#listname").css("background", "url('/images/ajax-loader.gif') no-repeat scroll 98% center #FFF"); $.ajax({ url: '/ajax/listname-update/index.cfm', data: ({listname: $("#listname").val().trim(), tasklistID: $("#tasklistID").val()}), dataType: 'json', type: 'post', success: function( result ) { // Update the name in the top, project list $("#list-" + $("#tasklistID").val()).find('a').html($("#listname").val().trim()); $("#list-" + $("#tasklistID").val()).effect('highlight', {color: '#BDC1C7'}, 500); //Remove the Ajax Spinner $("#listname").css("background", "#FFF"); $("#listname").effect('highlight', {color: '#BDC1C7'}, 500); //close the dialog $('#listeditdialog').dialog('close'); } }); return false; });

  • How to select an element by Class instead of ID in ASP.NET?

    - by firedrawndagger
    I have a few scatter elements which I am grouping together using a class like so - . In my code behind, using C# I want to hide these elements, using something like instructions.Visible = false;. However I realize I can only do this in codebehind if I use ID but this will result in invalid HTML/CSS Selector since you can't have multiple ID's with the same ID name... Alternatively is there another way to group the controls if not by class?

  • Included php file calling Javascript function

    - by Illes Peter
    Hi there! Here's the deal. I've got index.php which links to an internal JS file in it's header. index.php then includes another .php file, which outputs this: + add file. addFile() is a Javascript function defined in the external JS file. By doing this nothing happens, the included php does not "see" the JS function. Encapsulating the JS in the included PHP makes it all work. But I don't want to do it that way. Any ideas? EDIT: here's the source <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Archie</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <link rel="stylesheet" href="/screen.css" type="text/css" media="screen"/> <script src="/lib/js/archie.js" type="text/javascript"></script> </head> <body> ... ... //included php starts here <form action="/lib/course.php" method="post"> <fieldset> <div id="addFileLocation"></div> <a href="#" onClick="addFile()">+ add file</a> <input type="hidden" id="addFileCount" value="0"/> </fieldset> </form> //ends here ... ... </body> </html> and the js: <script type="text/javascript"> //Dynamically add form fields //add file browser function addFile() { var location = document.getElementById('addFileLocation'); var num = document.getElementById('addFileCount'); var newnum = (document.getElementById('addFileCount').value -1)+ 2; num.value = newnum; var newname = 'addFile_'+newnum; var newelement = document.createElement('input'); newelement.setAttribute('name',newname); newelement.setAttribute('type','file'); location.appendChild(newelement); } </script>

  • Lightweight use of Enterprise Library TraceListeners

    - by gWiz
    Is it possible to use the Enterprise Library 4.1 TraceListeners without using the entire Enterprise Library Logging AB? I'd prefer to simply use .NET Diagnostics Tracing, but would like to setup a listener that sends emails on Error events. I figured I could use the Enterprise Library EmailTraceListener. However, my initial attempts to configure it have failed. Here's what I hoped would work: <system.diagnostics> <trace autoflush="false" /> <sources> <source name="SampleSource" switchValue="Verbose" > <listeners> <add name="textFileListener" /> <add name="emailListener" /> </listeners> </source> </sources> <sharedListeners> <add name="textFileListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="..\trace.log" traceOutputOptions="DateTime"> <filter type="System.Diagnostics.EventTypeFilter" initializeData="Verbose" /> </add> <add name="emailListener" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.EmailTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging" toAddress="[email protected]" fromAddress="[email protected]" smtpServer="mail.example.com" > <filter type="System.Diagnostics.EventTypeFilter" initializeData="Verbose" /> </add> </sharedListeners> </system.diagnostics> However I get [ArgumentException: The parameter 'address' cannot be an empty string. Parameter name: address] System.Net.Mail.MailAddress..ctor(String address, String displayName, Encoding displayNameEncoding) +1098157 System.Net.Mail.MailAddress..ctor(String address) +8 Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.EmailMessage.CreateMailMessage() +256 Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.EmailMessage.Send() +39 Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.EmailTraceListener.Write(String message) +96 System.Diagnostics.TraceListener.WriteHeader(String source, TraceEventType eventType, Int32 id) +184 System.Diagnostics.TraceListener.TraceEvent(TraceEventCache eventCache, String source, TraceEventType eventType, Int32 id, String format, Object[] args) +63 System.Diagnostics.TraceSource.TraceEvent(TraceEventType eventType, Int32 id, String format, Object[] args) +198 System.Diagnostics.TraceSource.TraceInformation(String message) +14 Which leads me to believe the .NET Tracing code does not care about the "non-standard" config attributes I've supplied for emailListener. I also tried adding the appropriate LAB configSection declaration and: <loggingConfiguration> <listeners> <add toAddress="[email protected]" fromAddress="[email protected]" smtpServer="mail.example.com" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.EmailTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging" name="emailListener" /> </listeners> </loggingConfiguration> This also results in the same exception. I figure it's possible to programmatically configure the EmailTraceListener, but I prefer this to be config-driven. I also understand I can implement my own derivative of TraceListener. So, is it possible to use the Ent Lib TraceListeners, without using the whole Ent Lib LAB, and configure them from the config file? Update: After examining the code, I have discovered it is not possible. The Ent Lib TraceListeners do not actually utilize the config attributes they specify in overriding TraceListener.GetSupportedAttributes(), despite the recommendations in the .NET TraceListener documentation. Bug filed.

  • How do I compete the transformation matrix needed to transform a rectangle into a trapezium?

    - by Rich Bradshaw
    I'm playing around with css transforms and the equivalent filters in IE, and want to simulate perspective by transforming a 2d rectangle into a trapezium. Specifically, I want the right hand side of the rectangle to stay the same height, and the left hand side to be say 80% of the height, so that the mid points of both sides are horizontally in line with each other. I'm familiar with matrix algebra, but can't think how to determine what matrix will do that.

  • Learning PHP: Good examples of "build-this" based lessons?

    - by DavidR
    Last summer I learned HTML and CSS for a job, mainly through tutorials and a sort of "build this" method, that is, I'm given a goal and have to try to figure out how to build it myself. Is there a place with some examples to teach someone with this method? My boss wants to get me going on PHP this summer, and I need to refamiliarize myself with it over the next week. Most people send me to Php.net to follow the documentation, is there another good method out there?

  • Is Prince the best way to PDF in Ruby on Rails?

    - by Angela
    After several Google searches, it appears that the way to create PDF's in Rails from HTML and CSS (versus a new markup language) is to use Prince. With licensing at $3800 for my non-big-commercial app, I'm wondering if this is, in fact, consensus or people have an alternative they can share the what's and how's.

  • Meraki's Accounting-Requests to RADIUS server

    - by PachinSV
    I'm running a RADIUS server with some Meraki APs, the process of Authentications is fine... But it seems that the Meraki Cloud Controller is just sending the authentication packets and not the accounting requests. I've tested the RADIUS sending accounting requests with the radclient tool (locally) and it worked. I think that maybe my RADIUS server is ignoring the accounting requests from the MCC because there are some Vendor Specific Attributes that my RADIUS doesn't know. should I add a Meraki's dictionary to my RADIUS configurations? I'm kind of desperate, any idea?

  • How to tell when an HTML textarea has been changed by Javascript

    - by at
    A widget I'm using modifies an HTML textarea element. I need to know when that element has been modified and preferably I'd like to actually hide that element as well. I'm using jQuery, so I naturally tried the $('#textarea_id').change() event. But it's never triggered because I guess the textarea never loses focus. What's the best way to monitor that textarea, preferably hidden (css has display:none)? Please don't tell me setInterval...

  • MVC3/Razor Client Validation Not firing

    - by Jason Gerstorff
    I am trying to get client validation working in MVC3 using data annotations. I have looked at similar posts including this MVC3 Client side validation not working for the answer. I'm using an EF data model. I created a partial class like this for my validations. [MetadataType(typeof(Post_Validation))] public partial class Post { } public class Post_Validation { [Required(ErrorMessage = "Title is required")] [StringLength(5, ErrorMessage = "Title may not be longer than 5 characters")] public string Title { get; set; } [Required(ErrorMessage = "Text is required")] [DataType(DataType.MultilineText)] public string Text { get; set; } [Required(ErrorMessage = "Publish Date is required")] [DataType(DataType.DateTime)] public DateTime PublishDate { get; set; } } My cshtml page includes the following. <h2>Create</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @using (Html.BeginForm()) { @Html.ValidationSummary(true) Post <div class="editor-label"> @Html.LabelFor(model => model.Title) </div> <div class="editor-field"> @Html.EditorFor(model => model.Title) @Html.ValidationMessageFor(model => model.Title) </div> <div class="editor-label"> @Html.LabelFor(model => model.Text) </div> <div class="editor-field"> @Html.EditorFor(model => model.Text) @Html.ValidationMessageFor(model => model.Text) Web Config: <appSettings> <add key="ClientValidationEnabled" value="true" /> <add key="UnobtrusiveJavaScriptEnabled" value="true" /> Layout: <head> <title>@ViewBag.Title</title> <link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" /> <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> So, the Multiline Text annotation works and creates a text area. But none of the validations work client side. I don't know what i might be missing. Any ideas?? i can post more information if needed. Thanks!

  • jQuery post request is not sent until first post request is compleated

    - by Champ
    I have a function which have a long execution time. public void updateCampaign() { context.Session[processId] = "0|Fetching Lead360 Campaign"; Lead360 objLead360 = new Lead360(); string campaignXML = objLead360.getCampaigns(); string todayDate = DateTime.Now.ToString("dd-MMMM-yyyy"); context.Session[processId] = "1|Creating File for Lead360 Campaign on " + todayDate; string fileName = HttpContext.Current.Server.MapPath("campaigns") + todayDate + ".xml"; objLead360.createFile(fileName, campaignXML); context.Session[processId] = "2|Reading The latest Lead360 Campaign"; string file = File.ReadAllText(fileName); context.Session[processId] = "3|Updating Lead360 Campaign"; string updateStatus = objLead360.updateCampaign(fileName); string[] statusArr = updateStatus.Split('|'); context.Session[processId] = "99|" + statusArr[0] + " New Inserted , " + statusArr[1] + " Updated , With " + statusArr[2] + " Error , "; } So to track the Progress of the function I wrote a another function public void getProgress() { if (context.Session[processId] == null) { string json = "{\"error\":true}"; Response.Write(json); Response.End(); }else{ string[] status = context.Session[processId].ToString().Split('|'); if (status[0] == "99") context.Session.Remove(processId); string json = "{\"error\":false,\"statuscode\":" + status[0] + ",\"statusmsz\":\"" + status[1] + "\" }"; Response.Write(json); Response.End(); } } To call this by jQuery post request is used reqUrl = "AjaxPages/lead360Campaign.aspx?processid=" + progressID + "&action=updatecampaign"; $.post(reqUrl); setTimeout(getProgress, 500); get getProgress is : function getProgress() { reqUrl = "AjaxPages/lead360Campaign.aspx?processid=" + progressID + "&action=getProgress"; $.post(reqUrl, function (response) { var progress = jQuery.parseJSON(response); console.log(progress) if (progress.error) { $("#fetchedCampaign .waitingMsz").html("Some error occured. Please try again later."); $("#fetchedCampaign .waitingMsz").css({ "background": "url(common/images/ajax_error.jpg) no-repeat center 6px" }); return; } if (progress.statuscode == 99) { $("#fetchedCampaign .waitingMsz").html("Update Status :"+ progress.statusmsz ); $("#fetchedCampaign .waitingMsz").css({ "background": "url(common/images/ajax_loded.jpg) no-repeat center 6px" }); return; } $("#fetchedCampaign .waitingMsz").html("Please Wait... " + progress.statusmsz); setTimeout(getProgress, 500); }); } But the problem is that I can't see the intermediate message. Only the last message is been displayed after a long lime of ajax loading message Also on the browser console I just see that after a long time first requested is completed and after that the second request is completed. but there should be for getProgress ? I have checked jquery.doc and it says that $post is an asynchronous request. Can anyone please explain what is wrong with the code or logic?

  • Sporadic disk clicking sound

    - by Abdó
    Hi, I'm having some unusual and sporadic hard disk clicking issues. Here is a cronological description of the facts. I'm using an ASUS P6T-SE with Intel Core i7, 6Gb RAM 600W Power supply and ATI4670 graphics, running Ubuntu 10.10. About one month ago my hard disk (SATA II Seagate Barracuda 1Tb 7200 rpm) started making a clicking sound: a sort of loud tic-tac, every second or so, when involved in disk activity. The system was clearly slower than before at disk access, but it was functional and I could not find any signal of trouble on the linux logs. I disconnected the disk and tried an older SATA drive I had around: no problem with it. Then I reconnected the Seagate disk, and the problem was mysteriously gone. Ubuntu booted normally, usual speed, no clicking. A couple of weeks later, the problem reappeared. I tried disconnecting reconnecting (as it somehow solved the problem before) without luck. So, despite it was a rather new drive, I assumed it was a hardware issue, made backups and bought a new drive. The new drive is a SATA II Seagate Barracuda 1.5 Tb 7200 rpm. I installed both drives at the same time, with the intention of transferring my files from on to the other. To my surprise, when I booted the computer with both drives, both started making the clicking sound !! Even worse, I removed the old drive, leaving the unformated new drive connected, and booted from a LiveCD. It kept clicking ! Puzzled by this, I tried both drives on my laptop with a SATA to USB cable. At the moment I connected any of them, they made one or two unusual clicks and immediately stopped doing that and worked normally. The old drive I thought almost dead, was working like a charm as if nothing happened. Then I thought: "ok, it must be the motherboard. Let's try again". So, I reconnected the old drive to the ASUS P6T motherboard (the same cables and SATA port as before), and it worked as if nothing happened ! The problem was gone again. The new 1.5 Tb drive was also working ok: No clicking nor slowdown. So I left the old 1Tb disk connected and kept using the computer daily during 3 weeks, until today it happened again. Now I don't really know what to do or check. I'm not even sure if it is a hardware issue any more ! This is rather annoying as it seems it happens with a period of 2 or 3 weeks and I have no means of forcing it to happen. Does anyone have a clue of what can causes this behaviour or have any suggestions of things I should check when it happens again ? What I did today is checking some SMART parameters Error log: smartctl -l error /dev/sda. No errors Short selftest: smartctl -t short /dev/sda. No errors Disk Health check: smartctl -H /dev/sda. passed And here are the vendor specific parameters (smartctl -A /dev/sda) Which I'm not quite sure how to interpret. === START OF READ SMART DATA SECTION === SMART Attributes Data Structure revision number: 10 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x000f 120 099 006 Pre-fail Always - 235962588 3 Spin_Up_Time 0x0003 095 095 000 Pre-fail Always - 0 4 Start_Stop_Count 0x0032 100 100 020 Old_age Always - 187 5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 0 7 Seek_Error_Rate 0x000f 072 060 030 Pre-fail Always - 16348045 9 Power_On_Hours 0x0032 096 096 000 Old_age Always - 3590 10 Spin_Retry_Count 0x0013 100 100 097 Pre-fail Always - 0 12 Power_Cycle_Count 0x0032 100 100 020 Old_age Always - 94 183 Runtime_Bad_Block 0x0032 100 100 000 Old_age Always - 0 184 End-to-End_Error 0x0032 100 100 099 Old_age Always - 0 187 Reported_Uncorrect 0x0032 100 100 000 Old_age Always - 0 188 Command_Timeout 0x0032 100 097 000 Old_age Always - 4295164029 189 High_Fly_Writes 0x003a 100 100 000 Old_age Always - 0 190 Airflow_Temperature_Cel 0x0022 070 057 045 Old_age Always - 30 (Lifetime Min/Max 19/31) 194 Temperature_Celsius 0x0022 030 043 000 Old_age Always - 30 (0 18 0 0) 195 Hardware_ECC_Recovered 0x001a 037 026 000 Old_age Always - 235962588 197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 0 198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age Always - 0 240 Head_Flying_Hours 0x0000 100 253 000 Old_age Offline - 73950746906346 241 Total_LBAs_Written 0x0000 100 253 000 Old_age Offline - 1832967731 242 Total_LBAs_Read 0x0000 100 253 000 Old_age Offline - 3294986902 Any clue to this mystery will be really welcome.

  • Various problems with software raid1 array built with Samsung 840 Pro SSDs

    - by Andy B
    I am bringing to ServerFault a problem that is tormenting me for 6+ months. I have a CentOS 6 (64bit) server with an md software raid-1 array with 2 x Samsung 840 Pro SSDs (512GB). Problems: Serious write speed problems: root [~]# time dd if=arch.tar.gz of=test4 bs=2M oflag=sync 146+1 records in 146+1 records out 307191761 bytes (307 MB) copied, 23.6788 s, 13.0 MB/s real 0m23.680s user 0m0.000s sys 0m0.932s When doing the above (or any other larger copy) the load spikes to unbelievable values (even over 100) going up from ~ 1. When doing the above I've also noticed very weird iostat results: Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 0.00 1589.50 0.00 54.00 0.00 13148.00 243.48 0.60 11.17 0.46 2.50 sdb 0.00 1627.50 0.00 16.50 0.00 9524.00 577.21 144.25 1439.33 60.61 100.00 md1 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 md2 0.00 0.00 0.00 1602.00 0.00 12816.00 8.00 0.00 0.00 0.00 0.00 md0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 And it keeps it this way until it actually writes the file to the device (out from swap/cache/memory). The problem is that the second SSD in the array has svctm and await roughly 100 times larger than the second. For some reason the wear is different between the 2 members of the array root [~]# smartctl --attributes /dev/sda | grep -i wear 177 Wear_Leveling_Count 0x0013 094% 094 000 Pre-fail Always - 180 root [~]# smartctl --attributes /dev/sdb | grep -i wear 177 Wear_Leveling_Count 0x0013 070% 070 000 Pre-fail Always - 1005 The first SSD has a wear of 6% while the second SSD has a wear of 30%!! It's like the second SSD in the array works at least 5 times as hard as the first one as proven by the first iteration of iostat (the averages since reboot): Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 10.44 51.06 790.39 125.41 8803.98 1633.11 11.40 0.33 0.37 0.06 5.64 sdb 9.53 58.35 322.37 118.11 4835.59 1633.11 14.69 0.33 0.76 0.29 12.97 md1 0.00 0.00 1.88 1.33 15.07 10.68 8.00 0.00 0.00 0.00 0.00 md2 0.00 0.00 1109.02 173.12 10881.59 1620.39 9.75 0.00 0.00 0.00 0.00 md0 0.00 0.00 0.41 0.01 3.10 0.02 7.42 0.00 0.00 0.00 0.00 What I've tried: I've updated the firmware to DXM05B0Q (following reports of dramatic improvements for 840Ps after this update). I have looked for "hard resetting link" in dmesg to check for cable/backplane issues but nothing. I have checked the alignment and I believe they are aligned correctly (1MB boundary, listing below) I have checked /proc/mdstat and the array is Optimal (second listing below). root [~]# fdisk -ul /dev/sda Disk /dev/sda: 512.1 GB, 512110190592 bytes 255 heads, 63 sectors/track, 62260 cylinders, total 1000215216 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00026d59 Device Boot Start End Blocks Id System /dev/sda1 2048 4196351 2097152 fd Linux raid autodetect Partition 1 does not end on cylinder boundary. /dev/sda2 * 4196352 4605951 204800 fd Linux raid autodetect Partition 2 does not end on cylinder boundary. /dev/sda3 4605952 814106623 404750336 fd Linux raid autodetect root [~]# fdisk -ul /dev/sdb Disk /dev/sdb: 512.1 GB, 512110190592 bytes 255 heads, 63 sectors/track, 62260 cylinders, total 1000215216 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0003dede Device Boot Start End Blocks Id System /dev/sdb1 2048 4196351 2097152 fd Linux raid autodetect Partition 1 does not end on cylinder boundary. /dev/sdb2 * 4196352 4605951 204800 fd Linux raid autodetect Partition 2 does not end on cylinder boundary. /dev/sdb3 4605952 814106623 404750336 fd Linux raid autodetect /proc/mdstat root # cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sdb2[1] sda2[0] 204736 blocks super 1.0 [2/2] [UU] md2 : active raid1 sdb3[1] sda3[0] 404750144 blocks super 1.0 [2/2] [UU] md1 : active raid1 sdb1[1] sda1[0] 2096064 blocks super 1.1 [2/2] [UU] unused devices: Running a read test with hdparm root [~]# hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 664 MB in 3.00 seconds = 221.33 MB/sec root [~]# hdparm -t /dev/sdb /dev/sdb: Timing buffered disk reads: 288 MB in 3.01 seconds = 95.77 MB/sec But look what happens if I add --direct root [~]# hdparm --direct -t /dev/sda /dev/sda: Timing O_DIRECT disk reads: 788 MB in 3.01 seconds = 262.08 MB/sec root [~]# hdparm --direct -t /dev/sdb /dev/sdb: Timing O_DIRECT disk reads: 534 MB in 3.02 seconds = 176.90 MB/sec Both tests increase but /dev/sdb doubles while /dev/sda increases maybe 20%. I just don't know what to make of this. As suggested by Mr. Wagner I've done another read test with dd this time and it confirms the hdparm test: root [/home2]# dd if=/dev/sda of=/dev/null bs=1G count=10 10+0 records in 10+0 records out 10737418240 bytes (11 GB) copied, 38.0855 s, 282 MB/s root [/home2]# dd if=/dev/sdb of=/dev/null bs=1G count=10 10+0 records in 10+0 records out 10737418240 bytes (11 GB) copied, 115.24 s, 93.2 MB/s So sda is 3 times faster than sdb. Or maybe sdb is doing also something else besides what sda does. Is there some way to find out if sdb is doing more than what sda does? UPDATE Again, as suggested by Mr. Wagner, I have swapped the 2 SSDs. And as he thought it would happen, the problem moved from sdb to sda. So I guess I'll RMA one of the SSDs. I wonder if the cage might be problematic. What is wrong with this array? Please help!
