can't read data store meta-data: Input/output error

[Manoj Dahal]

Hi,

If I run the s3backer command as following:

s3backer --accessFile=passwd-s3fs --baseURL=http://s3.amazonaws.com/ --blockSize=4K --size=2G --debug --listBlocks --vhost bucket s3backmnt

or even
s3backer --accessFile=passwd-s3fs --blockSize=4K --size=2G --debug --listBlocks --vhost bucket s3backmnt

then I get the following error:

s3backer: auto-detecting block size and total file size...
s3backer: can't read data store meta-data: Input/output error


The followings are the debug logs:

I looked at the previous posts, but was not able to identify the problem. The bucket permissions have listing/upload/delete/view permission to everyone.
I can operate on the bucket from the AWS management console without any problems.

Here in the command and the logs the original bucket name is replaced with the word 'bucket'.

Please let me know if you have any clue about this issue.

Thanks in advance,

~Manoj

Try adding the --debug-http and -f flags to run in the foreground and show the HTTP traffic. There should be an error message embedded in the 400 response that may give you a hint to what the problem is.

Also, why are you using --baseURL ? Perhaps Amazon is rejecting this because its not HTTPS.

Specifying the bucket location with "region" option works fine for me.

Thanks,
