  • Using the same local folder for Dropbox and Skydrive

    - by roryok
    Ever since I switched to windows phone I've sorely missed having an official dropbox app. Recently I've toyed with the idea of moving all my crucial files to SkyDrive instead. I have more storage on SkyDrive and the WP SkyDrive integration is very handy. I'm thinking about having both cloud sync services point to the same local folder for the first few weeks. That way if I want to go back its an easy task (and I can keep using dropbox's superior public folder) Has anyone else done this? Are there any potential issues (permissions, conflicts etc)

  • Moving software RAID to Linux

    - by terman
    I'm using a RAID 1 (mirrored pair) configuration in my Media Center/ NAS system. Currently it's running Windows 8 (yeah, big mistake I know) and I'm regretting it (did it for the games, not worth it). Currently I'm having two software RAID 1s (3TB + 2TB) configured with Storage Spaces and unfortunately formatted with NTFS. Now I would like to switch to Fedora (or maybe Ubuntu if there are advantages) for good. Is there a way that I could continue using the disks as they are without the need to format them with ext or something? I'm glad for every tip. Oh, the system disk is of cause not in a raid configuration.

  • Build Advise for Home Web/NAS Server with Ubuntu Server 12.04 [closed]

    - by razor7
    I need to have a personal Webserver with NAS capabilities. The Webserver to test some LAMP projects I develop for clients, and also NAS to be able to stream media to local network. I want to have full control of the box, so I'm planning to build it with some spare parts and Ubuntu Server. The services/software that will run are (remember, is for personal and testing use only): SAMBA/CIFS SSH Server Apache 2 MySQL 5 Mercurial Repo PHP 5.3 Ruby on Rails OwnCloud Dovecot Webmin Postfix PureFTPd ClamAV The Hardware: Intel Dual Core E2180 2.0 GHz MSI P35 Neo Kinkston 1GB DDR2, 667 MSI Nvidia 7300le PCIe x16 256mb RAM HDD SATA WD Green 2TB x2 (RAID-1 with MDADM RAID Controller) 16 GB USB Pendrive (For server system installation) My idea is to build this system, using the pendrive for the Ubuntu Server software, and packages, and the RAID-1 for gross data storage. What do you think? Thanks a lot!

  • Does the Dell Inspiron 1501 handle more than 4 Gb of RAM?

    - by zillion
    After the following comment on my last question, I'm thinking about upgrading my RAM: I got a 160 GB Scorpio Blue a couple months ago for my 1501. It's nice. That + 2 GB Crucial RAM have rather revived my notebook (meaning a very nice speed and storage boost). I was outgrowing it... – Nathaniel What would be the best choice to add more RAM? I've already got 2 GB, but I'm not sure what their speed is. What are the size, type and speed limitations for RAM on my particular laptop?

  • Type 1 Hypervisor on the desktop

    - by Blazemore
    I have a powerful home PC, and I've used VirtualBox to run Linux distros in Windows (and vice versa). I'm interested in trying out a lightweight type 1 hypervisor to run all my operating systems (Windows 7, Debian, Arch) and was looking for suggestions of which to pick and how to implement this. From what I gather, a type 1 hypervisor is a lightweight OS which simply provides VM management functionality. Will I get reasonable performance under each guest OS? Can all the guest OSs have access to a shared data drive, or is is best to have a storage server in another guest OS and mount it over the virtual network? What about gaming, is this feasible, or will I realistically need to run Win7 on bare metal? I'd appreciate any input.

  • Suggestions for hosted file sharing services

    - by Jon
    Before I pose my question, I will give some insight as per my scenario: I work for a small business (cost is an important factor) Our bandwidth is limited and would not support an in-house FTP server We need to share files (mostly pdf, inDesign, Illustrator documents) to our clients, and as we expand, we are finding that our current locally-hosted FTP solution is too slow and is becoming a detriment to our sales team. What we need is a remotely hosted solution to share files with our clients, specifically with the following features: Greater than 100gb of secure storage The Ability to distribute unique log in credentials to clients, granting access to a personalized directory or folder, while limiting access to other files on the server. A relatively simple web-based UI for clients with limited computer knowledge We have considered a dedicated remote server, and web-based services (box.net, yousendit.com, onehub.com, filesanywhere.com) but I am unsure as per the direction we should be taking - have I left another solution out? What would you suggest? Thanks in advance.

  • Raid-3 like software backup tool

    - by Chronial
    I have a lot of data (about 7 TB), stored across multiple hard-drives with varying sizes. I would like to have a backup of that data to be safe against drive failure. A RAID is not a good option for me, as I want to keep my cost low and be able to easily extend the storage capacity of my setup by buying an additional HD. I remember seeing a piece of software that generates parity data over all drives and stores that on an extra drive. That solution protects the setup from hard drive failure and works with varying drive sizes (as long as the parity drive is the biggest one). But I can’t seem to find that software again. Does anybody now what I’m talking about or have any other solution for my situation?

  • Why hasn't anyone made a way for TimeMachine to wirelessly backup to Amazon S3?

    - by Jordan
    Seriously. I'm looking at you, Apple. If TimeMachine is supposed to be 'simple backup that just works' why is it impossible to backup into my S3 filespace? Why hasn't some 3rd party developer (JungleDrive???) made it so that TimeMachine will be OK with backing up to amazon s3 storage? It just seems like the most convenient, robust answer. I'd gladly pay the $20-25 a month for complete, unlosable backups that I can sync with wirelessly on a proper scheme.

  • Unable to format/add a partition to Windows XP

    - by sma
    I recently add a 1T disk to an XP machine. I found the disk in the "disk management", I click "initialize" to init it, then creates a primary partition with size 950G, then select quick format to format the disk, the "disk management" will then complains: The disk configuration operation did not complete. Check the system event log for more information on the error. Verify the status of your storage devices before retrying. If that does not solve the problem, close the disk management console, then restart disk management or restart the computer. What could be the reason?

  • Detach Disk from deleted virtual machine

    - by user1628043
    I had an Virtual Machine running in Azure for a couple of weeks and suddenly it stopped responding. I shut it down and tried to restart it but that failed saying the VM faulted. I then deleted the VM which leaves the VHD file intact on my storage account. I was intending to try recreating a new VM using thie VHD from the first VM however, the OS disk and Data disk are both still marked as being attached to the original VM which no longer exists. Is there any way to detach these disks so I can use them to create a new VM?

  • RoR routing problem. Calling custom action, but getting redirected to show action

    - by conorgil
    I am working on a project in ruby on rails and I am having a very difficult time with a basic problem.

  • I have a 21TB array but only 16TB is visible from Windows

    - by Relentim
    CONTROLLER Raid Controller: 3Ware 9650SE-24M8 Disks: 21 x 1TB RAID5 Stripe 64KB WINDOWS OS: Windows Server 2003 SP2 32x Disk: Dynamic 19557.44GB Volume: Capacity 15832.19GB I guess my array must have a 4KB block size which is limiting it to 16TB. I think I would have to switch to a 64KB block size to be able to see a maximum of 256TB. Or create another unit on my controller to go above 16TB of storage. Unfortunately I have already added over 16TB, ideally I would like to shrink the array and reclaim the 5 disks that aren't doing anything. I don't think this is possible. More likely, can I change the block size so 20TB becomes visible in windows?

  • Linux virtual disk stripping or multi-path samba share?

    - by wachpwnski
    I am trying to build a file storage box for media. It needs to span two or more directories or partitions as one share. There are a few solutions but reasons why I want to avoid them, among these are: Using LVM2 for stripping. I don't really have the resources to back up everything on the volumes incase one HDD goes south. I would end up loosing everything. Maybe there is a better option for this to prevent data loss with hot swappable drives or some kind of raid. Using symbolic links in the share. This will get tedious every time a new sub-directory is added. Is there some kind of software raid I can use to merge two directories virtually? I am aware of the issue where /dev/hda1/media/file.1 and /dev/hdb1/media/file.1 both exist. But I'm sure there are some creative solutions for this.

  • Sql database dumps failing every night

    - by chaseman36
    Hey guys, I have sql05 and my maintenance plan which backs up a database to an external storage SAN, has been failing every night. Here is my error: Executing the query "BACKUP DATABASE [master] TO DISK = N'\\192.168.x.x\vmbackup\server\dbbackup\master_backup_201004222300.bak' WITH NOFORMAT, NOINIT, NAME = N'master_backup_20100422230002', SKIP, REWIND, NOUNLOAD, STATS = 10 " failed with the following error: "Cannot open backup device '\\192.168.x.x\vmbackup\server\dbbackup\master_backup_201004222300.bak'. Operating system error 5(Access is denied.). BACKUP DATABASE is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly. I googled this error and tried adding permissions to the backup device for network service as recommended at experts exchange, no dice. Does anyone have any ideas?

  • Excel - Variable number of leading zeros in variable length numbers?

    - by daltec
    The format of our member numbers has changed several times over the years, such that 00008, 9538, 746, 0746, 00746, 100125, and various other permutations are valid, unique and need to be retained. Exporting from our database into the custom Excel template needed for a mass update strips the leading zeros, such that 00746 and 0746 are all truncated to 746. Inserting the apostrophe trick, or formatting as text, does not work in our case, since the data seems to be already altered by the time we open it in Excel. Formatting as zip won't work since we have valid numbers less than five digits in length that cannot have zeros added to them. And I am not having any luck with "custom" formatting as that seems to require either adding the same number of leading zeros to a number, or adding enough zeros to every number to make them all the same length. Any clues? I wish there was some way to set Excel to just take what it's given and leave it alone, but that does not seem to be the case! I would appreciate any suggestions or advice. Thank you all very much in advance!

  • Image is not displaying in email template on 2nd time forward

    - by Don
    Good day Friends, I've a mass mailing program with simple mail templates (HTML and few Images). I've a problem with image display. My clients are not getting images in the mail. Sometimes they get a mail with all the images, But if they forward the same email to someone else, they can’t get the images in forwarded mail. I really don’t know what’s happening with the approach., most of the cases the 2nd time forwarded mail is not showing the images properly. For example, consider I send a mail to client A, Here, Client A will get a mail with Images. Further, If Client A forward the same message to Person B then Person B is not getting Images in the Forwarded email. I’m using the following Approach to Embed an image in the mail template: StringBuilder sb = new StringBuilder(" <some html content> <img src=\"cid:main.png\" alt=\"\" border=\"0\" usemap=\"#Map\"> </html content ends here>"); Attachment imgMain = new Attachment(Server.MapPath("main.png")); imgMain.ContentId = "main.png"; MailMessageObject.Attachments.Add(imgMain); Instead of attachment, I tried bypassing the Image path from server directly. Something like as follows: StringBuilder sb = new StringBuilder(" <some html content> <img src=\"www.mydomain.com/images/main.png\" alt=\"\" border=\"0\" usemap=\"#Map\"> </html content ends here>"); But, result is same, Please help to resolve this problem

  • Hyper-V: determine the guest's name given the GUID

    - by syneticon-dj
    How would I go about determining the guest's name given its GUID or vice-versa, preferably with only the Hyper-V/Server Core stock install at hands? Rationale: I am in favor of having a repository of dirty tricks to revert to when in great need. To immediately quiesce all (storage) operations of a VM guest without losing the state, I used to run kill 17 <all VM's virtual processes> (signaling SIGSTOP) and resumed afterwards using kill 19 <all VM's virtual processes> (signaling SIGCONT) in ESXi/vSphere shell. I tried the same technique with Hyper-V using Process Explorer's "Suspend" functionality on the vmwp.exe processes and it seemed to work. I have yet to find a way for easily identifying the processes to suspend, though - the vmwp command line is only listing a GUID.

  • ISCSI sessions appear from nowhere

    - by Maraca
    Hi, I am using Win2008 32bit Ent. running in Hyper-V with 2 LUNs over ISCSI connection (this is a MS cluster with one LUN being quorum and second as a storage). In ISCSI - target - details I see multiple sessions from same target (currently 7), however I am not sure where they are coming from as I have only one virtual NIC on this server. Sure enough 2 LUNs appear 7 times each in device manager or in disk manager. On the cluster partner however, I do not see that problem. There is only one session per target. Installing MPIO makes only difference - I am getting 8 sessions instead of 7 once I reboot. Does any one know what can cause this behavior?

  • Sharing RAM resources between 2 or more computers

    - by davee44
    I know there was a somewhat similar question before: How to share CPU or RAM? But, let me just specify it a little more... When Microsoft Windows requires more RAM capacity than available it uses a swap-file to temporarily store the data there, this is actually something like a hard-drive-based RAM. This technology is used for many years. Theoretically, it shouldn't be too hard to implement a similar technology that uses the RAM of different computer(s) in the network for temporary data storage. This just requires a software that runs on computers in the network that accepts and returns data from/to the main computer and keep that data in the RAM; plus the operation system of the main computer must have the ability to use computers in the network instead of (or in addition to) the swap-file. I wonder, are there any implementations of this idea? This would allow users to build RAM clusters using all of their home or office computers, that will boost the performance of a single computer for some development/gaming/video tasks, etc.

  • New Servers Active Directory and Exchange

    - by user3164638
    I have 3 Dell PowerEdge server, each with 2 quad-core processors. I am going to bring this office out of the stone-age network (P2P, share files on a flash drive, emails through Google, etc) and set up Active Directory and Exchange 2013. Our needs are not that great at the moment - our staff consists of approximately 40 people, and our network may eventually be managed by an external company. We need only one domain for our emails (though we may serve emails for a few other partners domains as well). I was thinking of setting something up like this: Server 1: Primary DC. Active Directory and Exchange on separate virtual machines. Server 2: Redundant of server 1. Server 3: Shared resources, storage, backups, etc. How would you utilize 3 servers for an Active Directory / Exchange setup for a small/medium office? We do have plans to grow, so my solution must be scalable, though I'm not sure that I want to split permissions, though I'd consider it if that was something that could be changed on down the road.

  • How can I add two models in one form, where one model is a has_many :through?

    - by Angela
    How do I model having multiple Addresses for a Company and assign a single Address to a Contact? Contacts belong_to a Company. A Company has_many Contacts. A Company also has_many Addresses. And each Contact has_one Address. I want to be able, whenever I create a New Contact, to access all the addresses in all Contacts that belong to the Company. Here is are my Models: class Company < ActiveRecord::Base attr_accessible :name, :phone, :addresses has_many :contacts has_many :addresses, :through => :contacts end class Contact < ActiveRecord::Base attr_accessible :first_name, :last_name, :title, :phone, :fax, :email, :company, :date_entered, :campaign_id, :company_name, :address belongs_to :company has_one :address accepts_nested_attributes_for :address end class Address < ActiveRecord::Base attr_accessible :street1 has_many :contacts end How do I create the View in the _form for Contacts so that I can 1) Add an Address when creating a Contact; 2) Display the options of the Address. Here is how I am doing step 1, which is just to add a new address for a new contact: <% f.fields_for :addresses do |builder| %> <p> <%= builder.label :street1, "Street 1" %> </br> <%= builder.text_field :street1 %> <p> Right now, what I have doesn't work. The console says I cannot mass-assign addresses when I hit "submit" on this New contact form.

  • Amazon - install a complete server on EBS

    - by user1169575
    is it possible to install a full working OS with a webserver, db, and all needed stuff on an EBS storage? If so, would I immediatly gain benefits by mounting this EBS on a better instance? Otherwise (if I cannot install a complete image, or if you don't think it's reasonable) can I install the software so that I only need to mount the EBS on a new instance to have it working? I purchased a Medium Reserved Instance, but when there will be the need to get a better instance I'd like to move the whole db/website, I'd simply buy a better instance and then attach the EBS. Is it possibile? I'm imaging about it like an hard drive that would be mounted on a better server. Of course, more RAM would allow me to increase caching limits, and that's ok, but I don't want to reinstall anything (the main website is a magentocommerce and it's pretty painful to move it). P.S. is the Standard EBS (100 IOPS) valid or do I need to choose a Provisioned IOPS (up to 1000 IOPS)?

  • Hooking up many different external HDs simultaneously

    - by cbizz
    I need a large amount of external storage for an upcoming project. I'm planning on purchasing 10 2TB external drives. I need them all hooked up to a single machine at the same time. What issues will I run into? I plan on using 2 power strips and having them all externally powered from the wall. I will use a USB hub to plug in all the drives. I need drive access time to be as fast as possible. I am using Ubuntu Linux(64 bit). Will I be able to mount 10 drives?

  • Keeping video viewing statistics breakdown by video time in a database

    - by Septagram
    I need to keep a number of statistics about the videos being watched, and one of them is what parts of the video are being watched most. The design I came up with is to split the video into 256 intervals and keep the floating-point number of views for each of them. I receive the data as a number of intervals the user watched continuously. The problem is how to store them. There are two solutions I see. Row per every video segment Let's have a database table like this: CREATE TABLE `video_heatmap` ( `id` int(11) NOT NULL AUTO_INCREMENT, `video_id` int(11) NOT NULL, `position` tinyint(3) unsigned NOT NULL, `views` float NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `idx_lookup` (`video_id`,`position`) ) ENGINE=MyISAM Then, whenever we have to process a number of views, make sure there are the respective database rows and add appropriate values to the views column. I found out it's a lot faster if the existence of rows is taken care of first (SELECT COUNT(*) of rows for a given video and INSERT IGNORE if they are lacking), and then a number of update queries is used like this: UPDATE video_heatmap SET views = views + ? WHERE video_id = ? AND position >= ? AND position < ? This seems, however, a little bloated. The other solution I came up with is Row per video, update in transactions A table will look (sort of) like this: CREATE TABLE video ( id INT NOT NULL AUTO_INCREMENT, heatmap BINARY (4 * 256) NOT NULL, ... ) ENGINE=InnoDB Then, upon every time a view needs to be stored, it will be done in a transaction with consistent snapshot, in a sequence like this: If the video doesn't exist in the database, it is created. A row is retrieved, heatmap, an array of floats stored in the binary form, is converted into a form more friendly for processing (in PHP). Values in the array are increased appropriately and the array is converted back. Row is changed via UPDATE query. So far the advantages can be summed up like this: First approach Stores data as floats, not as some magical binary array. Doesn't require transaction support, so doesn't require InnoDB, and we're using MyISAM for everything at the moment, so there won't be any need to mix storage engines. (only applies in my specific situation) Doesn't require a transaction WITH CONSISTENT SNAPSHOT. I don't know what are the performance penalties of those. I already implemented it and it works. (only applies in my specific situation) Second approach Is using a lot less storage space (the first approach is storing video ID 256 times and stores position for every segment of the video, not to mention primary key). Should scale better, because of InnoDB's per-row locking as opposed to MyISAM's table locking. Might generally work faster because there are a lot less requests being made. Easier to implement in code (although the other one is already implemented). So, what should I do? If it wasn't for the rest of our system using MyISAM consistently, I'd go with the second approach, but currently I'm leaning to the first one. But maybe there are some reasons to favour one approach or another?
