Print this reportReproduction of cache filesI reproduced cache files on Kashiwa cluster with missed GWF files due to the data transfer trouble reported in klog#34729 and klog#34741.
Reproduced files are 14382.ffl, 14382.cache, 14383.ffl, and 14383.cache in Cache_GPS and CacheSecond_GPS. There is no missed GWF files in Minute trend. Old cache files are still kept as *.bak in the same directory. Difference between old and new files are shown in the attachment files. Now all GWF files since resuming O4c can be accessed via cache files at Kashiwa.
By the way, current cache generation process cannot serve correct cache when unordered data transfer is occurred due to a delay on the data transfer process and a manual recovery operation is required. So I started to test a new code to provide cache files including a function to recover automatically in the case of instability of the data transfer in the personal space (kmst2:/home/takahiro.yamamoto/work/makeCache). After testing, this new code will be merged to the product version of cache generation. This new function can automatically respond to instability on the data transfer and/or on network itself in the case that the resend process works well like this time, but manual operation is still required for problems such as long term disconnections e.g. klog#14712. This new code can probably mitigate also a duplication issue such as klog#34595.
