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/rssmessag...

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

[critke]

Was using XFS on Ubuntu...

[SwellJoe]

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.

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!

That thread talks about XFS problems, not about EBS.

[critke]

Yes, but the problems seem to have to do with XFS and EBS.

[moe]

Wrong. According to the thread it's a kernel issue. Maybe read your own links before spreading FUD?

[critke]

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.
