(although with each block being transfered > synchronously with writes, I'm not sure if that number would actually > show useful information, now that I think about it) we have "ns nr dw dr", which are network send, read disk write, read ns may be higher than dw, since it inlcudes resync data blocks. unit is sectors (512 Byte). counters are only reset to zero when drbd is newly initialized, so when you (re)configure the drbd network, the network counters are reset, when you (re)configure the drbd disk, the disk counters are reset. you can easily "strategically monitor" using e.g. rrd-tools. if you equally monitor /proc/diskstats (obviously the lower level devices, drbd does not do any statistics there), and rrd-graph the results, thats about as good as it gets. or am I still missing something? -- : Lars Ellenberg Tel +43-1-8178292-0 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Schoenbrunner Str. 244, A-1120 Vienna/Europe http://www.linbit.com : __ please use the "List-Reply" function of your email client.
