Today Andreas Maus wrote: > A file handles point to an inode not to a path, so I think rrdcached > is still able to write data to the file handle. as far as I underrstand the inner workings of rrdcached it only access the file once it writes to it (aka flushes) this means that it can not know if the file exist or not at update time. After all the whole puropse of rrdcached is to minimize IO. Checking for rrd validity at update time would negate that purpose. if you work with rrdcached and modify the 'database' directly, I would suggest to stop cached first and then restart it. Same stories with all databases. cheers tobi -- Tobi Oetiker, OETIKER+PARTNER AG, Aarweg 15 CH-4600 Olten, Switzerland http://it.oetiker.ch [email protected] ++41 62 775 9902 / sb: -9900 _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
