I stopped using EBS after the EC2 instance just stopped responding - twice - each time after a few weeks. I was using an EBS volume for MySQL data storage. I am not satisfied that this problem has been fixed. I suggest you look at this thread before using EBS for production: http://developer.amazonwebservices.com/connect/rss/rssmessages.jspa?threadID=28968 http://developer.amazonwebservices.com/connect/rss/rssmessag...

That thread appears to be related to Debian (Lenny) and XFS only. Were you using XFS or ext3?

  Was using XFS on Ubuntu...

    I'm just curious...what sort of workload are you dealing with that makes XFS a rational choice? It's dramatically less well-tested than ext3, or even ReiserFS, on Linux, and its performance characteristics are not particularly compelling except for a few pretty specific cases. I have a history of tinkering with odd filesystems, but I wouldn't deploy anything other than ext3 to a production Linux server at this point in time.

That thread talks about XFS problems, not about EBS.
- critke 17y ago
  Yes, but the problems seem to have to do with XFS and EBS.

    Wrong. According to the thread it's a kernel issue. Maybe read your own links before spreading FUD?
    - critke 17y ago
      I don't care if it's the kernel or whatever else. I just know that the dang thing blew up on me twice. So you go and think about kernels and stuff - and have fun with EBS - I'm not using it anymore.

        So we have the classical PEBCAK here. You got bitten by technology that you don't understand. Don't blame the machine, blame yourself.

hm. I've been having the same problems when I try to do large postgres operations like index on my Ubuntu instance. I'd figured my configuration was messed up somehow. I'm really glad I came across this information!
