  • Configure nginx for multiple node.js apps with own domains

    - by udo
    I have a node webapp up and running with my nginx on debian squeeze. Now I want to add another one with an own domain but when I do so, only the first app is served and even if I go to the second domain I simply get redirected to the first webapp. Hope you see what I did wrong here: example1.conf: upstream example1.com { server 127.0.0.1:3000; } server { listen 80; server_name www.example1.com; rewrite ^/(.*) http://example1.com/$1 permanent; } # the nginx server instance server { listen 80; server_name example1.com; access_log /var/log/nginx/example1.com/access.log; # pass the request to the node.js server with the correct headers and much more can be added, see nginx config options location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_set_header X-NginX-Proxy true; proxy_pass http://example1.com; proxy_redirect off; } } example2.conf: upstream example2.com { server 127.0.0.1:1111; } server { listen 80; server_name www.example2.com; rewrite ^/(.*) http://example2.com/$1 permanent; } # the nginx server instance server { listen 80; server_name example2.com; access_log /var/log/nginx/example2.com/access.log; # pass the request to the node.js server with the correct headers and much more can be added, see nginx config options location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_set_header X-NginX-Proxy true; proxy_pass http://example2.com; proxy_redirect off; } } curl simply does this: zazzl:Desktop udo$ curl -I http://example2.com/ HTTP/1.1 301 Moved Permanently Server: nginx/1.2.2 Date: Sat, 04 Aug 2012 13:46:30 GMT Content-Type: text/html Content-Length: 184 Connection: keep-alive Location: http://example1.com/ Thanks :)

  • My Western Digital 500GB Passport disk says "not formatted" when I plug it in Windows

    - by learnerforever
    Hi, When I plug my Western Digital 500 GB Passport disk in my Windows machine, it says "not formatted, do you want to format it" something. I started having this problem after I put it in an old desktop at home. I don't exactly know what went wrong. May be partition table is corrupted etc. Questions: Some quick search on internet tells me there are partition fixing utilities, which can fix corrupted partition table. testdisk being one of such utiities. I can understand how to use this to copy files from the disk to some other location, but I would like to fix the partition table in-place so that I don't have to temporary move around my data of approx size 300GB, then format passport disk and then again bring back the data. Is there any way I can fix the partition table in-place? Also, how to know which file system was there originally in the disk? Can I only keep the same file system? My current laptop is running Windows 7. Earlier I used to use Windows Vista. My other laptop has Windows XP. So I have access to Windows 7 and Windows XP. Please help! Thanks,

  • How to HIDE "client denied by server configuration:" error in log

    - by Keith

  • Networking Problem MrxSmb event 50 "Delayed Write Failed" errors occurring all of the sudden

    - by Johnny Musso
    JUST THIS MONTH, we have started getting reports from a number of very stable clients that MrxSmb event id 50 errors keep appearing in their system event logs. Otherwise, they do not appear to have any networking problems except that there is a critical legacy application which seems to either be generating the MrxSmb errors or having errors occur because of them. The legacy application is comprised of 16 bit and 32 bit code and has not been changed or recompiled in many years. It has always been stable on Windows XP systems. The customers that have the problem usually have a small (5 clients or less) peer to peer network with all Windows XP systems. All service packs are loaded on the XP machines. Note: The only thing that seems to correct the problem is disabling opportunistic locking. I don't like this solution because it seems to slow down the network and sometimes causes record locking issues between users (on some networks). Also, this seems to have just started happening - as if a Windows update for XP has caused it? However, I have removed recent updates and it did not correct the issue. Thanks in advance for any help you can provide.

  • Bugzilla email issue

    - by xian
    My bugzilla system keep hit the following error: There was an error sending mail from '[email protected]' to '[email protected]':Can't send data I think that is some problem with my setting and configuration. First is the urlbase I have tried setting it to bugzilla.example.com, and http://127.0.0.1:81/, and http://10.0.0.236/ (My laptop IP address, I use this laptop to set up bugzilla) but the error still persists. Actually what should I put in the urlbase field? Parameter = Email Under mail_delivery_method, i choose SMTP. Under mailfrom, I put bugzilla-daemon. smtpserver, I tried leaving it blank, or setting it to 220.181.12.12 before, but could not solve my problem For my sql, the following is the data and command I used: C:\mysql\bin>mysql --user=root -p mysql Enter password: 1234 (When I install mysql into my laptop, it ask me to key an username and password, i have key in username as 'cvuser' and password as '1234', but here never ask me to key in any username) Welcome to the MySQL monitor.

  • Which database to use and system/db administration by layman [closed]

    - by blah
    So my friend and I got briliant ;) idea for a business. Since it is not predictable whether it will work out or not, we decided to keep cost as low as possible to start with, in particular not to hire anyone. If it will work out as expected it will generate enough profit to hire professionals in few months. But for the first few months we'll be doing everything by ourselfs. He's a business/finance major, and I'm a software developer, so obviously I have to take care of IT :) It will be a webapp, written in python/django. My questions regarding this project: 1) What database should I choose? I'm experienced with oracle, and have been working with SQL Server for a while, but both of them are too expensive(at least now). It's a developer experience, I've never done any dba stuff. I'm looking for something free(as in beer). Looks like MySql or PostgreSQL are most popular in this sector. I would appreciate any comments on which db to choose. I'm open to any suggestions(it doesn't have to be MySql or Postgre). Here's what I know about data: It will be almost dates and numbers, a little bit of text. Searched mainly by dates. Data will almost never be updated, mostly inserted and browsed. From 30k to 300k new records/month. 2) Servers. My idea is to rent two dedicated servers. During normal operation one would be a web server(debian/apache), other would be a db server(debian/?). My recovery plan is to install everything on both, and in case of trouble with one of machines just run everything on the other one. Does it even makes sense? Any other tips appreciated. Thanks.

  • How to find out which program a default beep is coming from in Windows 7?

    - by leeand00
    There's a "default beep" (as defined in System Sounds) that emanates from my computer every so often. It kind of goes like this (where each number is a "default beep" sound): 1, 2, 3, 4, 5. So there's a distinct pattern to it. I thought I had this figured out a way to figure out what was happening by going to Control Panel-Ease of Access-Ease of Access Center-Replace sounds with visual cues But that just isn't the case. Whichever window I click on, that one displays the visual queue when this happens. It's driving me crazy, and I can't figure out which program is causing this. Update: it appears to only happen on one user profile on the computer...does that help? Update 2: Discovered that this sound was coming from a utility on my laptop called ASUS NB Probe; I'm certain that it is emanating from this program because the error message displayed by it changes in sync with the sound playing. Apparently the S.M.A.R.T. feature of my hard drive was reporting an issue. It displays the issue for a brief second and then makes it disappear, I'll have to keep watching it to see what it says, but I believe is says something about a read. I have an external hdd connected with eSATA to a container of sorts (BlacX) that you can plug two hdds into. I have one hdd attached and it's a Western Digital WD1001FALS - 00E8B0 Thanks again! Now I'm off to go around the Internet and report on this...since I posted it so many places!

  • Permissions on mac for itunes library with multiple users - idea

    - by John
    I currently have a lot of music on an external drive and my itunes set up from there. However, periodically, when the external drive isn't connected, itunes will default back to the library location of my home directory user path. I don't want to mess with an external drive, as my mac HD is large enough to house the music collection. However, I have 4 family members - all with their own logins - using this same gob of music. I don't want 4 copies of the library, only one with all libraries referencing it. So, what I want to do is: 1 - move all music files to a shared directory at /Macintosh HD/users/music. I created this directory and adjusted permissions, so all four users can read and write to this directory. 2 - get all four accounts to reference this library instead of the external or local home locations I am hoping I can just check the box to keep library organized in my account, which is the admin and let itunes move it all. Then delete current libraries for each account and re-add from the new shared location. Will the itunes organization process cause permissions issues either by setting permissions to all the files access to my account only or write permissions or any other 'gotcha'? I am having a hard time coming up with a smooth solution that won't break everything and cause me to have mega duplicates or access issues. I would prefer not to do any xml library file editing if possible. Am I dreaming? Thanks for help.

  • .htaccess authorization requiring username/password for every resource

    - by webworm
    I am using Apache2 on Ubuntu and I have having some "weird" user authorization issues. I am using .htaccess to control access to my directories. I have many users and have grouped them into user groups which are defined in a "group" file. I then use .htaccess within each directory to define which users have access to the directory and which do not. Here is an example .htaccess file. AuthUserFile /var/local/.htpasswd AuthGroupFile /var/local/groups AuthName "Username and Password Required" AuthType Basic require group design admin Everything is working with one exception. I added a new user to one of my groups and though they can gain access to the directory they are prompted for a username and password for every resource (i.e. image, CSS). After a while I can just keep selecting "cancel" and I will get a page with just html with no images or CSS. I would think the browser would just cache the username/password. It seems to be working well for other users. Any thoughts?

  • How do I find funny pictures?

    - by Hanno Fietz
    No, not lolcats. And I'm not really looking for a specific site, either. I have often wished that I had some funny picture to illustrate a presentation, a website, a post, an email, or something else. Google image search and stock photo services have hardly ever helped me, although that may be because I'm doing something wrong. Jeff Atwood seems to have no problem to find funny pictures for his codinghorror and stackoverflow blogs, as well as for the error messages on the trilogy sites. One of my favourites was this elephant. Other bloggers also seem to be quite good at it. I'm wondering if I simply lack the creativity or if there's sources or methods I don't know about. I could think of the following ways to get pictures, but I'm not sure whether this is really "how they do it". keep a collection of pictures that you stumbled upon and liked (takes quite some time to build up to a proper library), when you need a picture, there's one in there maybe have pictures on paper, too, like from magazines or ads. when you are looking for a picture, search online (Flickr, Google, stock photos). This has never really worked for me, I don't know why. produce the pictures yourself, i. e. have a good library of source material or find some online and apply some creativity and suitable software. I could imagine that this could work well once you have the practice.

  • How to re-join an AD2003 domain with Samba after deleting the machine account?

    - by Guss
    During some troubleshooting I deleted the machine account for a Linux server running samba from our AD 2003 domain. We are using Kerberos for authentication, and after I deleted the machine account I tried to join the domain again using net ads join -U Administrator But I keep getting Kerberos errors like these: [2009/08/18 16:14:36, 0] libads/kerberos.c:ads_kinit_password(228) kerberos_kinit_password [email protected] failed: Client not found in Kerberos database Failed to join domain: Improperly formed account name It appears as if samba remembers that it once had an account with the AD and keeps trying to reconnect to it, but I want to create a new account from scratch. I tried to delete all the .tdb files I could find as well as everything under /var/cache/samba but to no avail - it still behaves the same. I also tried to create the machine account on the AD side, but then I get a similar error when I try to join, about failure to authenticate with the machine account - it looks like samba tries the previous machine account password and I don't know how to reset it, or even if I could figure out what samba uses - how to set it in the AD. Any help would be greatly appreciated, as at this point the only thing I can think about is to reformat and reinstall the machine, and I would really REALLY love to not do that. Thanks in advance.

  • Thunderbird alerts when expected email does not arrive

    - by user871199
    I am on Ubuntu 12.04 using Thunderbird as email client. Both are up to date in terms of updates. I have bunch of nightly jobs that do the work and send a status mail. It gets tedious if you keep getting same/similar mails every day so I ended up writing a mail filter rule which causes emails to end up in their respective folders automatically. If things are going ok, I really don't need to read emails. Failure emails are sent to different alias - if the job runs. We recently discovered that one of the job had not run for few days as someone accidentally disabled it. In order to avoid such problems in future, I would like to setup thunderbird in such a way that if I don't get email from given address within given duration, it should alert me. My dream solution is to set up frequency - some jobs do run every 4 hours. Is this possible? Can I setup Thunderbird (preferred) or other email client for reminding me when expected email does not show up. Based on comments and answer I received, here are the reasons why I would like to use Thunderbird. We are already using Thunderbird. It has calender support via plugin, so I suppose someone is already watching time to remind us about the event. May be this another type of event. Additional job is one more failure point, may complicate life if it has to monitor multiple hosts. Additional tools - same thing, one more failure point. Thunderbird can be run across all the platforms we are using - Windows and Ubuntu. It sort of becomes platform independent solution.

  • Why is Mac supposedly better than Windows for graphics?

    - by Svish
    Ok, people just keep telling me that if you're going to be working with graphics and design and stuff, you should get a Mac. And I just don't get the logic. Because most of these people would be working with Adobe software, which are for both Windows and Mac. To me it seems like their whole argument is based on that "everyone else does". Like, Mac had some graphics software that Windows didn't earlier in history, so most people were using Mac. And since most people were using Mac, new people also started using Mac. And since most people were using Mac, schools and universities used Mac. Which taught new people to use Mac. So they were using Mac. And told everyone they met that everyone they knew were using Mac. And so on. Anyways... What is the deal really? Is there actually any advantage in using Mac for graphics and design and such things? My take is that you pretty much have the same software and both Mac and Windows are powerful enough, support enough RAM, are stable (as long as you don't install lot's of junk or faulty drivers), et cetera. So, can anyone give me a good explanation on this? Is there a real difference or are people just brainwashed?

  • Running DNS locally for home network

    - by Roy Rico
    I have a small home network that just got larger ( New roommate, My existing roommate got a laptop (on top of her computer)j, my friends coming over with laptop, etc ). I'd like to run a local DNS server for lookups of my local network stuff (fileserver.local, windowsTV.local, machineA.local, machineB.local, appletv.local). I used to have a business line with a static IP, and run bind/named internally. However, now, I have a normal account. My ISP's DNS servers are constantly changing (for whatever reasons my ISP doesn't like to keep the same IP range for long). I need my local DNS to be automatically updated to use my ISP's DNS for external traffic, but be able to maintain an internal DNS server (getting to update the hosts file is being a hassle with every new machine on top of rebuilding existing machines with win7 or Ubuntu 9.04). Additionally, My ISP's DNS servers often crash or become unresponsive. Are there any open DNS servers that are reliable (i don't want to reconfig every day) that I could use as my primary, then if those fail, then use my ISP's? UPDATE: Also looking for each workstation to be able to use dhcp to connect, but instead of getting ISP dns servers, getting my internal one.... Thanks

  • Is basing storage requirements based on IOPS sufficient?

    - by Boden
    The current system in question is running SBS 2003, and is going to be migrated on new hardware to SBS 2008. Currently I'm seeing on average 200-300 disk transfers per second total across all the arrays in the system. The array seeing the bulk of activity is a 6 disk 7200RPM RAID 6 and it struggles to keep up during high traffic times (idle time often only 10-20%; response times peaking 20-50+ ms). Based on some rough calculations this makes sense (avg ~245 IOPS on this array at 70/30 read to write ratio). I'm considering using a much simpler disk configuration using a single RAID 10 array of 10K disks. Using the same parameters for my calculations above, I'm getting 583 average random IOPS / sec. Granted SBS 2008 is not the same beast as 2003, but I'd like to make the assumption that it'll be similar in terms of disk performance, if not better (Exchange 2007 is easier on the disk and there's no ISA server). Am I correct in believing that the proposed system will be sufficient in terms of performance, or am I missing something? I've read so much about recommended disk configurations for various products like Exchange, and they often mention things like dedicating spindles to logs, etc. I understand the reasoning behind this, but if I've got more than enough random I/O overhead, does it really matter? I've always at the very least had separate spindles for the OS, but I could really reduce cost and complexity if I just had a single, good performing array. So as not to make you guys do my job for me, the generic version of this question is: if I have a projected IOPS figure for a new system, is it sufficient to use this value alone to spec the storage, ignoring "best practice" configurations? (given similar technology, not going from DAS to SAN or anything)

  • Copying email with qmail and Plesk

    - by Greg
    I need to keep a copy of all outgoing and incoming email (for a single domain if possible) using qmail or Plesk. I can't recompile qmail, so qmailtap is out of the question, as is setting QUEUE_EXTRA in extra.h. I'm pretty sure it should be possible with Plesk's mailmng utility, aka Mail Handlers but I'm having trouble getting them to work. I've registered 2 hooks: incoming hook ./mailmng --add-handler --handler-name=incoming --recipient-domain=example.com --executable=/xxx/incoming.sh --context=/xxx/incoming/ --hook=before-local incoming.sh #!/bin/bash # The email is passed on stdin - grab it to a variable e=`cat -` # $1 = context (/xxx/incoming) # $3 = recipient ([email protected]) # Create /xxx/incoming/[email protected] mkdir -p $1$3 # Save the email to /xxx/incoming/[email protected]/0123456789.txt echo "$e" > $1$3/`date +%s%N`.txt # Echo PASS to stderr echo 'PASS' >&2 # Echo the email to stdout echo "$e" outgoing hook # ./mailmng --add-handler --handler-name=outgoing --sender-domain=holidaysplease.com --executable=/xxx/outgoing.sh --context=/xxx/outgoing/ --hook=before-remote The outgoing.sh file is the same as incoming.sh, except replace $3 (recipient) with $2 (sender). The incoming hook does work, but saves 2 copies of each email - one before and one after SpamAssassin has run. The outgoing hook doesn't seem to get called at all. So finally, my questions are: How can I make the incoming hook save only a single copy (preferably after SpamAssassin has run)? How can I get the outgoing hook to work?

  • redirect temporarily STDOUT to another file descriptor, but still to screen

    - by Carlos Campderrós
    I'm making a script that executes some commands inside, and these commands show some output on STDOUT (and STDERR as well, but that's no problem). I need that my script generates a .tar.gz file to STDOUT, so the output of some commands executed in the script also go to STDOUT and this ends with a not valid .tar.gz file in the output. So, in short, it's possible to output the first commands to the screen (as I still want to see the output) but not via STDOUT? Also I would like to keep the STDERR untouched so only error messages appear there. A simple example of what I mean. This would be my script: #!/bin/bash # the output of these commands shouldn't go to STDOUT, but still appear on screen some_cmd foo bar other_cmd baz #the following command creates a tar.gz of the "whatever" folder, #and outputs the result to STDOUT tar zc whatever/ I've tried messing with exec and the file descriptors, but I still can't get it to work: #!/bin/bash # save STDOUT to #3 exec 3>&1 # the output of these commands should go to #3 and screen, but not STDOUT some_cmd foo bar other_cmd baz # restore STDOUT exec 1>&3 # the output of this command should be the only one that goes to STDOUT tar zc whatever/ I guess I'm lacking closing STDOUT after the first exec and reopen it again or something, but I can't find the right way to do it (right now the result is the same as if I didn't add the execs

  • Installation of gearmand fails on libevent dependency

  • Color Printer: Laser vs Inkjet

    I am about to buy a color printer. I had a B&W Laserjet printer in the past but since then I've used inkjets for decades. I need a printer that can deliver high quality as these photo inkjet printers, but I'm tired of paying for ink that costs $9,000 per gallon (1 gallon = 3.785 liters = 300 cartridges = $9,000). So, I was thinking about buying a color laser printer, but I'm not sure these printers can deliver the same quality and are worth the investment in terms of toner consumption. I remembered that my old Laserjet printer was able to print 1100 pages per toner cartridge. The inkjet printers I have can print 500 pages per cartridge. Price by price, 2 inkjet cartridges have more or less the same cost as one toner cartridge and in theory prints almost the same. I am not sure if this is true for color lasers. What can you guys tell me about quality, toner cost and cost per page for laser or inkjet printer? Is it worth the change? (Keep in mind that an inkjet printer costs $50 and a laser printer costs $200.) Thanks.

  • Postfix Relay to Office365

    - by woodsbw
    I am trying to setup a Postfix server on a Linux box to relay all mail to our Office365 (Exchange, hosted by Microsoft) mail server, but, I keep getting an error regarding the sending address: BB338140DC1: to= relay=pod51010.outlook.com[157.56.234.118]:587, delay=7.6, delays=0.01/0/2.5/5.1, dsn=5.7.1, status=bounced (host pod51010.outlook.com[157.56.234.118] said: 550 5.7.1 Client does not have permissions to send as this sender (in reply to end of DATA command)) Office 365 requires that the sending address in the MAIL FROM and From: header be the same as the address used to authenticate. I have tried everything I can think of in the config to get this working. My postconf -n: append_dot_mydomain = no biff = no config_directory = /etc/postfix debug_peer_list = 127.0.0.1 inet_interfaces = loopback-only inet_protocols = all mailbox_size_limit = 0 mydestination = xxxxx, localhost.localdomain, localhost myhostname = localhost mynetworks = 127.0.0.0/8 recipient_delimiter = + relay_domains = our.doamin relayhost = [pod51010.outlook.com]:587 sender_canonical_classes = envelope_sender sender_canonical_maps = hash:/etc/postfix/sender_canonical smtp_always_send_ehlo = yes smtp_sasl_auth_enable = yes smtp_sasl_mechanism_filter = login smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = smtp_tls_CAfile = /etc/postfix/cacert.pem smtp_tls_loglevel = 1 smtp_tls_security_level = may smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_use_tls = yes sender_canonical: www-data [email protected] root [email protected] www-data@localhost [email protected] root@localhost [email protected] Also, sasl_passwd is set to the correct credentials (tested them using swaks multiple times.) Authentication works, and sends the message when the from headers are correct (also tested using swaks....which works) The emails are coming from PHP, so I have also tried altering the sendmail path in php.ini to use pass the correct from address via -f So, for some reason, mail coming from www-data and root are not having the from fields rewritten to Office 365's satisfaction, and it won't send the message. Any postfix gurus out there that can help me setup this relay?

  • Why can't I see installed AIR applications in /Applications on Mac OS Lion?

    - by Damir Zekic
    Yesterday I did a clean install of Mac OS Lion, and installed bunch of apps, including HipChat Desktop Application (an Adobe AIR app). I used it for some time and eventually closed it. Today I wanted to start it again, but couldn't find it in Launchpad. I looked in /Applications folder, but I couldn't find it there either (I still don't have ~/Applications). I went back to HipChat website (from where I installed) and a Flash plugin allowed me to run the app immediately. It shows up in my Dock and if I "keep it" there, I can launch it again (it still doesn't appear in my /Applications dir). However, it asks me for confirmation about launching an app that has been downloaded from the Internet (every time I start it, it's annoying). I also see the app in Adobe AIR uninstaller. I then went to my old Snow Leopard installation and found HipChat in my /Applications folder there. Copied it to the Lion disk and it works. Now I have two HipChat entries in Adobe AIR uninstaller. I guess I solved the issue at hand, but I still don't understand where the original app is located and how I can access it and move it to Applications. I couldn't find it anywhere with both Finder search nor find command in terminal (I used $find / -name "HipChat*" -print). So, how does Adobe AIR store the installed applications (on OSX Lion) and is there any way to get them to show up in Launchpad?

  • How do I know what hardware to buy to meet my needs?

    - by Darth Android
    While Stack Exchange does not permit shopping recommendations, it doesn't provide any general advice to consider when buying hardware. So, instead of just telling those that ask what to buy that it's not allowed, let's tell them how to figure out what they need. When looking forward to build a computer, how do I know what to buy? How do I find out if a given CPU will be enough for a certain game or application that I want to run? How do I find out if a given graphics card will be enough for a certain game or application? What is important when looking at motherboards? How much memory do I need? How do I know how much wattage I need for a power supply? What size case do I need? What relevant standards do I need to read up on and be aware of? PCI, PCIe, SATA, USB 2.0, USB 3.0, etc... What "gotchas" do I need to be on the lookout for? Please keep responses generation-agnostic to ensure they will be helpful to our future users. :)

  • PostgreSQL failover cluster on Windows Server

    - by user36997
    We are looking for advice on how to setup a basic failover cluster for our application: We will be using 4 machines running Microsoft Windows Server (most probably 2003). All four will always run our application, which is essentially a web service. Load balancing is "outsourced" - somebody else handles the distribution of the web requests among the servers. Only one of the servers will be running the PostgreSQL server actively at any given time. Another server (of the four) also has the DB installed, but is on standby/passive. The DB data is stored on shared storage. No copying data between servers. Reads are done very frequently by many end-users, and in rather small chunks of data. Writes are done much less frequently, by less users, and in very large bulks of data. Now, how can one configure Microsoft Cluster Service to keep only one instance of the DB server and 4 instances (1 per server) of our application at all times? And does PostgreSQL integrate neatly with MSCS at all? Update: Instead of keeping the data on shared storage, I also consider using log shipping to replicate data on a couple of DB servers. There are two issues with this option: Log shipping only makes sure that I have a second server that gets all of the data and is ready to take over. How do I implement the actual failure detection and failover switch? Switching back: Suppose the master fails and the system automatically fails over to the slave, and later the master comes back online. I understand that with WAL shipping this will require to reconfigure the log shipping once again, and that switching back is far from seamless. Is that so?
