  • MicroSD card getting corrupted for no good reason

    - by ChaosR
    I recently bought an MicroSD card online. It's a Sandisk 16GB class 2. However, it has a nasty problem. Every time I fill it with my data, the fat tables get corrupted. I've tried reformatting it, blanking it, doesn't seem to solve the problem. I have tried windows and linux (ubuntu), both have the problem. I've used my usb microsd readers, and even tried putting it in my phone and putting data on it from there. All have this problem. Now the really odd thing is, besides the corrupted file tables, no programs can find anything wrong with the hardware. I've tried both chkdisk and "badblocks -w", neither give any type of error. Now I don't know if the actual data gets corrupted, or if its just filesystem tables. What happens is that one or more folders start showing a load of chinese-charred (random UTF8 symbols I suppose) folders and files, and it is impossible to do anything with those. All the other data (outside of the corrupted folders) seems fine. I've tried to test it, and the problem doesn't seem to show up until I fill the disk upto about 3~4GB. After that I can still access the data. But as soon as I eject/safely remove/unmount it, the bad things happen somehow. Next time I plug it in, the folders I most recently wrote to (but sometimes also the folders I wrote the time before last time to) are all gibberish. Does anybody have any clue what might be going on here? EDIT: It seems I can't even put ext3 or ext4 on it, they both complain about a corrupted journal. Gheh, guess something is really broken here.

  • Correct MySQL username/password, but getting Access Denied error when run from script

    - by Nick
    I'm currently trying to run the following command from within a shell script. /usr/bin/mysql -u username -ppassword -h localhost database It works perfectly fine when executed manually, and not from within a script. When I try to execute a script that contains that command, I get the following error: ERROR 1045 (28000) at line 3: Access denied for user 'username'@'localhost' (using password: YES) I literally copied and pasted the working command into the script. Why the error? As a sidenote: the ultimate intent is to run the script with cron. EDIT: Here is a stripped down version of my script that I'm trying to run. You can ignore most of it up until the point where it connects to MySQL around line 19. #!/bin/sh #Run download script to download product data cd /home/dir/Scripts/Linux /bin/sh script1.sh #Run import script to import product data to MySQL cd /home/dir/Mysql /bin/sh script2.sh #Download inventory stats spreadsheet and rename it cd /home/dir /usr/bin/wget http://www.url.com/file1.txt mv file1.txt sheet1.csv #Remove existing export spreadsheet rm /tmp/sheet2.csv #Run MySQL queries in "here document" format /usr/bin/mysql -u username -ppassword -h localhost database << EOF --Drop old inventory stats table truncate table table_name1; --Load new inventory stats into table Load data local infile '/home/dir/sheet1.csv' into table table_name1 fields terminated by ',' optionally enclosed by '"' lines terminated by '\r\n'; --MySQL queries to combine product data and inventory stats here --Export combined data in spreadsheet format group by p.value into outfile '/tmp/sheet2.csv' fields terminated by ',' optionally enclosed by '"' lines terminated by '\r\n'; EOF EDIT 2: After some more testing, the issue is with the << EOF that is at the end of the command. This is there for the "here document". When removed, the command works fine. The problem is that I need << EOF there so that the MySQL queries will run.

  • VBA + Polymorphism: Override worksheet functions from 3rd party

    - by phi
    my company makes extensive use of a data provider using a (closed source) VBA plugin. In principal, every query follows follows a certain structure: Fill one cell with a formula, where arguments to the formula specify the query the range of that formula is extended (not an arrray formula!) and cells below/right are filled with data For this to work, however, a user has to have a terminal program installed on the machine, as well as a com-plugin referenced in VBA/Excel. My Problem These Excelsheets are used and extended by multiple users, and not all of them have access to the data provider. While they can open the sheet, it will recalculate and the data will be gone. However, frequent recalculation is required. I would like every user to be able to use the sheets, without executing a very specific set of formulas. Attempts remove the reference on those computers where I do not have terminal access. This generates a NAME error i the cell containing the query (acceptable), but this query overrides parts of the data (not acceptable) If you allow the program to refresh, all data will be gone after a failed query Replace all formulas with the plain-text result in the respective cells (press a button and loop over every cell...). Obviously destroys any refresh-capabilities the querys offer for all subsequent users, so pretty bad, too. A theoretical idea, and I'm not sure how to implement it: Replace the functions offered by the plugin with something that will be called either first (and relay the query through to the original function, if thats available) or instead of the original function (by only deploying the solution on non-terminal machines), which just returns the original value. More specifically, if my query function is used like this: =GETALLDATA(Startdate, Enddate, Stockticker, etc) I would like to transparently swap the function behind the call. Do you see any hope, or am I lost? I appreciate your help. PS: Of course I'm talking about Bloomberg... Some additional points to clarify issues raise by Frank: The formula in the sheets may not be changed. This is mission-critical software, and its way too complex for any sane person to try and touch it. Only excel and VBA may be used (which is the reason for the previous point...) It would be sufficient to prevent execution of these few specific formulas/functions on a specific machine for all excel sheets to come This looks more and more like a problem for stackoverflow ;-)

  • Does RAID 1 protect against corruption?

    - by Shaun
    Does Raid 1 protect against data corruption? For example, let's say that I am keeping all of my important files on a NAS that uses 2 disks in a RAID 1. If one hard drive has some kind of internal problem and the data becomes corrupted, does the RAID recognize this automatically and correct it using data from the other good disk? Could it even know which copy is the good one? Does RAID 5 protect against corruption? I know that RAID is not a backup solution. I am trying to figure out how to make sure that I am not backing up corrupt data!

  • How to configure 1080p HDTV as a monitor

    - by Robot
    I've read several posts that almost answer my question, but not quite. I have a Samsung LN32C530 1080p HDTV I'd like to use as a monitor. I was reasonably successful getting the prior 720p model to work ok using SwitchResX, but I think I just got lucky with the parameters (1360x768@60Hz). I tried the expected (1920x1080@60Hz) values and "nearby" ones, with no luck. Older 720p params actually work, but I get the same small real estate as the older model TV. Trying values near 1080p always displays an image that doesn't match the screen size and is very jagged which makes me think interpolation is making things worse. Also, SwitchResX has a bunch of parameters other than H x W ("porch" etc), and I don't know how they all work together. Any help?

  • USB Wireless keyboards not registering Ctrl Alt Delete when computer boots

    - by Donovan
    I've recently installed a new PC at work. Its a Dell Optiplex 9010. I bought a USB wireless keyboard and mouse from Dell and subsequently from Logitech to use with this PC. The Dell keyboard is a model KM632 and the logitech is an mk260. Both units work properly and have decent range. The issue is when the PC boots they keyboard (neither model) will register a Ctrl+Alt+Delete to the PC. I can say for sure the keyboards are still functional as the media keys will still produce a result (notably the sleep key on the mk260). My gut reaction is I'm dealing with an issue in the PC or Windows. I'm not sure where to start though. If I unplug and reinsert the USB dongle both units will work. Also, I don't use both they keyboards at the same time I bought the Logitech fearing the Dell unit was bad. Any ideas would be appreciated.

  • Trigger ZFS dedup one-off scan/rededup

    - by Jake Wharton
    I have a ZFS filesystems which has been running for some time and I recently had the opportunity to upgrade it (finally!) to the latest ZSF version. Our data doesn't scream dedup but I firmly believe based on small tests that we could gain anywhere from 5-10% of our space back for free by utilizing it. I have enabled dedup on the filesystem and new files are slowly being dedupified but the majority (95%+) of our data already exists on the filesystem. Short of moving the data off-pool and then recopying it back, is there any way to trigger a dedup scan of existing data? It doesn't have to be asynchronous or live. (And FYI there isn't enough room on the pool to copy the entire filesystem to another and then just switch the mounts.)

  • Very High Network out in ec2 instance

    - by Jatin
    I launched an ubuntu-14.04-64bit instance in Amazon EC2 two days back. And I started Tomcat 7.0.54 in that instance and deployed my application war files. It has no other software installed other than tomcat and the default ones. In the past 2 days, its shows 858 GB of Data Transfer(Network Out) from that instance. I have attached a graph of Amazon CloudWatch Metric "Network Out" My application does not do any data download/upload. Its a Java Spring application and the front end is in HTML&Javascript. My application traffic was very low (less than 20 hits) in those 2 days. Is there a way to find out why these data transfers happened and also to find what data has been transferred. If you can see in graph, network out was 20gb per minute. Some more info: Network in was negligible CPU Utilization was very high Everything else was low

  • IF commands in a batch file

    - by Rossaluss
    I'm writing a small batch file to replace users' themes and charts in Office and I have the below batch file that works just fine. cd c:\documents and settings\%username%\application data\microsoft\templates echo Y|rmdir charts /s mkdir charts echo Y|del "c:\documents and settings\%username%\application data\microsoft\templates\document themes\*.*" net use o: \\servername\sms copy "o:\ppt themes\charts\*.*" "c:\documents and settings\%username%\application data\microsoft\templates\charts" copy "o:\ppt themes\Document Themes\*.*" "c:\documents and settings\%username%\application data\microsoft\templates\document themes" c: net use o: /delete Now what I want is the above to only run if it hasn't run before as we'll be pushing this out to all users for around 2 weeks to catch people that aren't in every day. Is there any way to begin the command with something to look for one of the new themes/charts already pushed down, and if it's present, then have it not run? Any help on this would be greatly appreciated as I'm pretty new to these batch files.

  • Apache permission Problems

    - by swg1cor14
    Ok all my files and folders are set as owner of vsftpd:nogroup. FTP program can upload and create and do everything. But when I use the PHP command mkdir, I get a Permission Denied even though the folder its creating it in is set to chmod 777. IF i set the base folder to user www-data and group www-data, PHP mkdir will work. However, I can't use FTP to delete or upload to that folder. /uploads is base folder. I use PHP mkdir to create a directory in there: if (!is_dir($_SERVER['DOCUMENT_ROOT'] . "/uploads/" . $_REQUEST['clientID'] . '/video/')) { @mkdir($_SERVER['DOCUMENT_ROOT'] . "/uploads/" . $_REQUEST['clientID'] . '/video/', 0777); } If /uploads is vsftpd:nogroup then PHP mkdir will give a Permission Denied error. If /uploads is www-data:www-data then PHP mkdir WILL work, but I cant continue to FTP anything in that folder that was just created. If /uploads is vsftpd:www-data then PHP mkdir will give a Permission Denied error. How can I create a directory with PHP and still be able to access it via FTP?

  • Preparing laptops for theft

    - by ccook
    With a number of laptops out there the likelihood of one being stolen is high. What methods, preferably free, can be used to secure the data on the computers? The laptops do not have any special hardware on them, and generally keep their user data in a dropbox folder. One small step taken is to have the the dropbox folder encrypted by Windows 7. Any additional suggestions are greatly appreciated. The data in the dropbox folder is sensitive.

  • Having Troubles Getting My Apache Server Online(NodeJS and Apache)

    - by Jeff Armingol
    I am new here. This is my situation. I am using nodejs modules, serialport2 and socket.io, because I am trying to forward the data from my arduino hardware through serialports. In my server side script, I read the data then forward it to the client side. Now I am using Apache to serve the html page,which is the client side. I am running Nodejs on port 8000 and Apache on port 80. It is running OKAY when I view it in my browser typing localhost:80. The data is appearing and seems fine. Now when I tried to get my Apache server online using a Free DDNS provider(http://www.noip.com/) and my port80, it loaded the webpage but there are no data appearing on the page. What seems to be the problem here? Really need your expertise and advice. Thanks in advanced!

  • How can I set up conditional formatting to highlight a range only if all its cells are empty?

    - by Jennifer
    I am new to conditional formatting and having a hard time. I have 6 columns with 100 rows. What I would like to have happen is to highlight the row in one color if there is no data in it at all. If there is data in one cell within the row, however, I would like for the highlighting to be removed from the row completely. Currently I have it set up to highlight the entire row if there is no data in it and if there is data in one cell, only that cell has no highlighting....I can't seem to make the entire row's highlighting disappear. I have used the formula to determine which cells to format: =I16:N16="" formatting color is yellow. I know I have to add a second conditional format but I have tried numerous different formulas and cant seem to get it to work.

  • Unusually high dentry cache usage

    - by Wolfgang Stengel
    Problem A CentOS machine with kernel 2.6.32 and 128 GB physical RAM ran into trouble a few days ago. The responsible system administrator tells me that the PHP-FPM application was not responding to requests in a timely manner anymore due to swapping, and having seen in free that almost no memory was left, he chose to reboot the machine. I know that free memory can be a confusing concept on Linux and a reboot perhaps was the wrong thing to do. However, the mentioned administrator blames the PHP application (which I am responsible for) and refuses to investigate further. What I could find out on my own is this: Before the restart, the free memory (incl. buffers and cache) was only a couple of hundred MB. Before the restart, /proc/meminfo reported a Slab memory usage of around 90 GB (yes, GB). After the restart, the free memory was 119 GB, going down to around 100 GB within an hour, as the PHP-FPM workers (about 600 of them) were coming back to life, each of them showing between 30 and 40 MB in the RES column in top (which has been this way for months and is perfectly reasonable given the nature of the PHP application). There is nothing else in the process list that consumes an unusual or noteworthy amount of RAM. After the restart, Slab memory was around 300 MB If have been monitoring the system ever since, and most notably the Slab memory is increasing in a straight line with a rate of about 5 GB per day. Free memory as reported by free and /proc/meminfo decreases at the same rate. Slab is currently at 46 GB. According to slabtop most of it is used for dentry entries: Free memory: free -m total used free shared buffers cached Mem: 129048 76435 52612 0 144 7675 -/+ buffers/cache: 68615 60432 Swap: 8191 0 8191 Meminfo: cat /proc/meminfo MemTotal: 132145324 kB MemFree: 53620068 kB Buffers: 147760 kB Cached: 8239072 kB SwapCached: 0 kB Active: 20300940 kB Inactive: 6512716 kB Active(anon): 18408460 kB Inactive(anon): 24736 kB Active(file): 1892480 kB Inactive(file): 6487980 kB Unevictable: 8608 kB Mlocked: 8608 kB SwapTotal: 8388600 kB SwapFree: 8388600 kB Dirty: 11416 kB Writeback: 0 kB AnonPages: 18436224 kB Mapped: 94536 kB Shmem: 6364 kB Slab: 46240380 kB SReclaimable: 44561644 kB SUnreclaim: 1678736 kB KernelStack: 9336 kB PageTables: 457516 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 72364108 kB Committed_AS: 22305444 kB VmallocTotal: 34359738367 kB VmallocUsed: 480164 kB VmallocChunk: 34290830848 kB HardwareCorrupted: 0 kB AnonHugePages: 12216320 kB HugePages_Total: 2048 HugePages_Free: 2048 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 5604 kB DirectMap2M: 2078720 kB DirectMap1G: 132120576 kB Slabtop: slabtop --once Active / Total Objects (% used) : 225920064 / 226193412 (99.9%) Active / Total Slabs (% used) : 11556364 / 11556415 (100.0%) Active / Total Caches (% used) : 110 / 194 (56.7%) Active / Total Size (% used) : 43278793.73K / 43315465.42K (99.9%) Minimum / Average / Maximum Object : 0.02K / 0.19K / 4096.00K OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME 221416340 221416039 3% 0.19K 11070817 20 44283268K dentry 1123443 1122739 99% 0.41K 124827 9 499308K fuse_request 1122320 1122180 99% 0.75K 224464 5 897856K fuse_inode 761539 754272 99% 0.20K 40081 19 160324K vm_area_struct 437858 223259 50% 0.10K 11834 37 47336K buffer_head 353353 347519 98% 0.05K 4589 77 18356K anon_vma_chain 325090 324190 99% 0.06K 5510 59 22040K size-64 146272 145422 99% 0.03K 1306 112 5224K size-32 137625 137614 99% 1.02K 45875 3 183500K nfs_inode_cache 128800 118407 91% 0.04K 1400 92 5600K anon_vma 59101 46853 79% 0.55K 8443 7 33772K radix_tree_node 52620 52009 98% 0.12K 1754 30 7016K size-128 19359 19253 99% 0.14K 717 27 2868K sysfs_dir_cache 10240 7746 75% 0.19K 512 20 2048K filp VFS cache pressure: cat /proc/sys/vm/vfs_cache_pressure 125 Swappiness: cat /proc/sys/vm/swappiness 0 I know that unused memory is wasted memory, so this should not necessarily be a bad thing (especially given that 44 GB are shown as SReclaimable). However, apparently the machine experienced problems nonetheless, and I'm afraid the same will happen again in a few days when Slab surpasses 90 GB. Questions I have these questions: Am I correct in thinking that the Slab memory is always physical RAM, and the number is already subtracted from the MemFree value? Is such a high number of dentry entries normal? The PHP application has access to around 1.5 M files, however most of them are archives and not being accessed at all for regular web traffic. What could be an explanation for the fact that the number of cached inodes is much lower than the number of cached dentries, should they not be related somehow? If the system runs into memory trouble, should the kernel not free some of the dentries automatically? What could be a reason that this does not happen? Is there any way to "look into" the dentry cache to see what all this memory is (i.e. what are the paths that are being cached)? Perhaps this points to some kind of memory leak, symlink loop, or indeed to something the PHP application is doing wrong. The PHP application code as well as all asset files are mounted via GlusterFS network file system, could that have something to do with it? Please keep in mind that I can not investigate as root, only as a regular user, and that the administrator refuses to help. He won't even run the typical echo 2 > /proc/sys/vm/drop_caches test to see if the Slab memory is indeed reclaimable.

  • Freebsd 7.2: View firmware version for disks?

    - by Stefan Lasiewski
    I'm running FreeBSD 7.2, with Seagate Cheetah (Model ST####) drives. We are having some problems with the SCSI drives on these machines. Our vendor says that updating the firmware on the drives may fix the problems, and a firmware update did seem to fix some SCSI problems on another FreeBSD host. How can I view the firmware version of these drives? I tried some tips from nixCraft, but nothing has worked so far. In dmesg, I see the Make and Model, but In Linux, this information is often in /var/log/dmesg (Although /var/log/dmesg is sometimes out of date), or I often find this information with something like sudo lshw -class disk, lshal or dmidecode.

  • Ubuntu 12.04 Server: permissions on /var/www for newly copied files

    - by Abe
    I ran the following commands to set up ACL on the /var/www folder in my Ubuntu 12.04 Server: sudo usermod -g www-data abe sudo chown -R www-data:www-data /var/www sudo chmod -R 775 /var/www I downloaded Wordpress using wget in my /var/www folder and unzipped the downloaded file: cd /var/www wget http://wordpress.org/latest.zip mv latest.zip wordpress.zip unzip wordpress.zip I created a new database and user in mysql and attempted to run the setup process through the web interface. When I enter the configuration info in wordpress I run into the following error message: Sorry, but I can't write the wp-config.php file. When I run ls -la, I see that the files are owned by my user abe, but they are part of the group www-data. Would I have to run the chmod command every time I copy new files to /var/www? sudo chmod -R 775 /var/www

  • Insertion of rows without changing formulas on anohter sheets

    - by julie
    I have two separate spreadsheets which feed each other (one person completes the main one so all others autofill). I have set up formulas so it autofills but when I insert new lines into the main spreadsheet the other spreadsheet takes information from the wrong line, even though the new data was put in the place of the old data. (The new inserted lines were put in where the data was before). can anyone help me to "protect" the formulas from movement? I will appreciate any help.

  • High disk time on sql-server

    - by Patrik
    Hi We have a dedicated sql-server 2008 r2 enterprise edition. The setup is: D: (data files) - stored on local ssd disks (not the same disks as log files) (raid 10) E: (log files) - stored on local ssd disks (not the same disks as data files) (raid 1) F: (transaction log backup) - stored remote on a SAN Today we moved our log files to new disks (from F: to E:). From a shared volume ( F:(SAN)) to dedicated local disks (E:). What then happend was that the "disk time", "avg. transfer time" and "avg disk write queue length" increased on the volume where we have the data files (D:) (not on the volume where the log files are located). The data volume and log volume does not share disks, however they share the same controller card. "Disk idle time" is low for all volumes. One thought is ofcourse that the controller card might be overloaded. But, we need more ideas on where the problem might be.

  • Windows Event Viewer - XML Custom Filter

    - by Frank
    <QueryList> <Query Id="0" Path="Application"> <Select Path="Application"> *[EventData[Data and (Data="Error")]] </Select> </Query> </QueryList> I believe the above XML custom filter would work if I wanted to check for Events where "Data" equals the word "Error". However, what I want to express is that I want the Events where Data CONTAINS the word "Error" . . . how do I express that? I've Goggled around, but I can find no references to Regular Expression like pattern matching in the Event Viewer. XPath has "contains", but if Event Viewer will support it, I cannot seem to figure out the syntax for invoking it.
