Having these messages in = the debug ringbuffer is annyoing for sure, but seeing it make its way into your syslog is what really drove me a bit mad (esp. as Proxmox seems to poll blo= ck devices in a weird way, which generated such messages at a rate of several dozen entries per minute...). I made rsyslog (on Debian Squeeze) discard the kind of message by introduci= ng a regex filter to its chain of rules by creating a file "/etc/rsyslog.d/zz-local.conf" with the following lines as its content: :msg, regex, ".*sending ioctl [0-9][0-9]* to a partition.*" ~ :msg, regex, ".*scsi_verify_blk_ioctl: [0-9][0-9]* callbacks suppressed.*" ~ Maybe that's helpful for someone who doesn't like getting their logs spammed with pretty meaningless noise, too. --=20 with best regards: - Johannes Truschnigg ( johannes@truschnigg.info ) www: http://johannes.truschnigg.info/ phone: +43 650 2 133337 xmpp: johannes@truschnigg.info Please do not bother me with HTML-email or attachments.
