After a reboot on 4.8 I ended up with a degraded raid 5 partition...=20 The only thing special about my setup is.... 4944 drives spread over 3 = channels, running SMP kernel..... One sub disk was down and the and the drive was referenced... in = scouring the=20 mailing lists I saw where a referenced disk means you have referenced a = non-existent drive - I read this as one vinum didn't think was = defined.. in my=20 case it was drive29 --> /dev/da29s1e I don't know how this got referenced !!! It's been reboot many times = and this has not happened. =20 So I boldly created a config file for vinum and re-created the = drive..... --- config file ---- drive drvie29 device /dev/da29e --- end ---- but I still can not start the sub disk.....=20 (root@jammin) /home/staff/mikej# vinum start raid5-1.p0.s15 Can't start raid5-1.p0.s15: Drive is down (5) (root@jammin) /home/staff/mikej#=20 Here is what vinum thinks...... Do I rm the sub disk and re-create = it????? Will this kill my raid-5 partition ?? Thanks !!
