Hi, Here is the config, before I exchanged da0 with a raw disk. # Vinum configuration of , saved at Fri Jan 25 09:44:32 2002 drive vinumdrive0 device /dev/da0e drive vinumdrive1 device /dev/da1e drive vinumdrive2 device /dev/da0f drive vinumdrive3 device /dev/da1f drive vinumdrive4 device /dev/da0g drive vinumdrive5 device /dev/da1g volume var volume docsis volume docsisvar plex name var.p0 org concat vol var plex name var.p1 org concat vol var plex name docsis.p0 org concat vol docsis plex name docsis.p1 org concat vol docsis plex name docsisvar.p0 org concat vol docsisvar plex name docsisvar.p1 org concat vol docsisvar sd name var.p0.s0 drive vinumdrive0 plex var.p0 len 2096887s driveoffset 265s plexoffset 0s sd name var.p1.s0 drive vinumdrive1 plex var.p1 len 2096887s driveoffset 265s plexoffset 0s sd name docsis.p0.s0 drive vinumdrive2 plex docsis.p0 len 12582647s driveoffset 265s plexoffset 0s sd name docsis.p1.s0 drive vinumdrive3 plex docsis.p1 len 12582647s driveoffset 265s plexoffset 0s sd name docsisvar.p0.s0 drive vinumdrive4 plex docsisvar.p0 len 46515878s driveoffset 265s plexoffset 0s sd name docsisvar.p1.s0 drive vinumdrive5 plex docsisvar.p1 len 46515878s driveoffset 265s plexoffset 0s I guess I know what makes the trouble. To be able to boot ! from da0, which also has a root partition on it, I changed SCSI ID's, so my old da1 got da0. And vinum cannot deal with this. I really should be able to tell vinum that vinumdrive1 is indead vinumdrive2, since the device ordering has changed. But I really do not want to restore my root partition from backup, if I still have a working cold mirror. That is nonsense. > vinum list? eblcom# vinum list 3 drives: D vinumdrive1 State: up Device /dev/da0s1e Avail: 0/1024 MB D vinumdrive3 State: up Device /dev/da0s1f Avail: 0/6144 MB D vinumdrive5 State: up Device /dev/da0s1g Avail: 0/22712 MB D vinumdrive0 State: referenced Device Avail: 0/0 MB D vinumdrive2 State: referenced Device Avail: 0/0 MB D vinumdrive4 State: referenced Device Avail: 0/0 MB 3 volumes: V var State: up Plexes: 2 Size: 1023 MB V docsis State: up Plexes: 2 Size: 6143 MB V docsisvar State: up Plexes: 2 Size: 22 GB 6 plexes: P var.p0 C State: faulty Subdisks: 1 Size: 1023 MB P var.p1 C State: up Subdisks: 1 Size: 1023 MB P docsis.p0 C State: faulty Subdisks: 1 Size: 6143 MB P docsis.p1 C State: up Subdisks: 1 Size: 6143 MB P docsisvar.p0 C State: faulty Subdisks: 1 Size: 22 GB P docsisvar.p1 C State: up Subdisks: 1 Size: 22 GB 6 subdisks: S var.p0.s0 State: crashed PO: 0 B Size: 1023 MB S var.p1.s0 State: up PO: 0 B Size: 1023 MB S docsis.p0.s0 State: crashed PO: 0 B Size: 6143 MB S docsis.p1.s0 State: up PO: 0 B Size: 6143 MB S docsisvar.p0.s0 State: crashed PO: 0 B Size: 22 GB S docsisvar.p1.s0 State: up PO: 0 B Size: 22 GB It seems to me that reviveing the mirrors does not work as supposed. By the way. I found the command which made such problems: have a configfile like such: # cat /root/configfile drive vinumdrive0 device /dev/da1e drive vinumdrive2 device /dev/da1f drive vinumdrive4 device /dev/da1g and execute vinum create /root/configfile twice ! makes STABLE 4.5RC3 crashing with a double fault. I guess we should fix that. I'm makeing now a debug kernel. If I try to take the configfile as described above, from the original creation, I get vinum hanging and get unkillable, or I get a segfault from vinum.
