Due to periodically running out of space on EBS volumes on AWS EC2, and looking to make the setup more fault resistant in case of server/volume failure, I'm considering moving a Dovecot maildir installation over to S3QL.
- Would there be any problem(s) with such a setup? If so, what would they be?
- I notice at https://code.google.com/p/s3ql/wiki/other_s3_filesystems that it doesn't support multiple mounts from different computers. The other filesystems that, according to the table, do support multiple mounts, don't seem to be in existence/maintained any more. Are there any suitable alternatives that do support being mounted from multiple servers at the same time? If the filesystem supported this, would Dovecot essentially support the simultaneous access to the same maildirs from multiple servers?
- Are there any other, better, ways of handling the issue of maildir space & reliability?
