#103darcs hub is generating too many files, causing hosting problems
Darcs repos are accumulating duplicate patch files due to http://bugs.darcs.net/issue1987 . With a large number of darcs repositories collected in one place, this means eg right darcs hub is consuming over a million inodes (of 6 million allowed by the file system) which is too much for Linode's nightly backup system to handle. Currently the only workaround is to get fresh copies of all repos, which I did two months ago, but that's a tedious and risky procedure and two months later the problem is back in full force. http://bugs.darcs.net/patch1134 has just arrived and may help.
Update: it did help, and now darcs hub optimizes all repos nightly to garbage-collect junk files, and backups were re-enabled. But there are still too many files (2m) and the nightly backups are still taking too long (5-6h) so more work is needed here.
Update: this has been under control for a few months. Also, we migrated to newer SSD-based linode hardware. Currently we have 1M files and backups take 1.5h.
