The kernel on this amd64-based computer is now 2.6.16.20. LVM is version 2.02.05 (versions from Gentoo packages). Device mapper is 1.02.07 and udev is 090.) Since I'm shooting in the dark, cc'd to the gentoo ml since this system is gentoo-based (2005.0 profile). >/ 2006-06-12 01:06:30 -0400 >\ Maurice Volaski: >> Spontaneously and for no apparent reason, two computers displayed >>the following message in their logs several times at the same time: >> > > [55419.446442] Buffer I/O error on device hda, logical block 0 > > [55419.447381] hda: command error: status=0x51 { DriveReady >SeekComplete Error } >> [55419.447386] hda: command error: error=0x54 { AbortedCommand >>LastFailedSense=0x05 } >> [55419.447389] ide: failed opcode was: unknown >> [55419.447391] end_request: I/O error, dev hda, sector 0 >> >... >> drbd could at least theoretically triggered this somehow. >no. > >much more likely some program scanning ("discovering") devices. > >just a wild guess: >man lvm.conf >/filter -- Maurice Volaski, mvolaski@aecom.yu.edu Computing Support, Rose F.
