I just ran scap and saw the following for a lot of hosts:
srv285: rsync: write failed on "/usr/local/apache/common-local/php-1.19/cache/l10n/l10n_cache-ab.cdb": No space left on device (28)
srv285: rsync error: error in file IO (code 11) at receiver.c(302) [receiver=3.0.7]
srv285: rsync: connection unexpectedly closed (2051 bytes received so far) [generator]
srv285: rsync error: error in rsync protocol data stream (code 12) at io.c(601) [generator=3.0.7]
Also, on configchange:
mw21: rsync: write failed on "/apache/common-local/wmf-config/CommonSettings.php": No space left on device (28)
mw21: rsync error: error in file IO (code 11) at receiver.c(302) [receiver=3.0.7]
mw21: rsync: connection unexpectedly closed (37 bytes received so far) [generator]
mw21: rsync error: error in rsync protocol data stream (code 12) at io.c(601) [generator=3.0.7]
Not sure if this is a problem and/or if others are aware/working on it, but thought I'd mention it.
