And is there anything in your logfiles saying something like " > Device: /dev/sdb [SAT], 98 Currently unreadable (pending) sectors"? Interesting, I have this in /etc/smartd.conf DEVICESCAN -n standby -a -m root -s (L/../../6/00|S/../.././00) but according to the selftest logs it seems it is only checking sdb but *not* sda. I'll have to check this out. A manual short test succeeded. However, a failing disk should not affect LVM, should it? -- Markus
