I have been trying to setup a series of mirrors of disk partitions
with mixed results. I have multiple ide disks on multiple ide
controllers. Each controller has only a master drive no slaves.
Ultimately I want to end up with something like:
gmroota -> ad0s1, ad0s2 [ mirrored ]
M1 -> ad0s2, ad2s2 [ mirrored ]
M2 -> ad4s1, ad6s1 [ mirrored ]
M3 -> ad8s1, ad10s1 [ mirrored ]
M4 -> ad12s1, ad14s1 [ mirrored ]
gmdata -> M1, M2, M3, M4 [ concat ]
ad0 and ad2 same size disks sliced into two parts. ad0s1 and ad2s1 are
mirrored as gmroot. gmroot is bsdlabel partitioned: /, swap, var, tmp,
usr with the last partion 1 sector smaller then size of partition c: .
System boots fine.
ad0s2 and ad2s2 are bsdlabeled as one partition a: that is 1 sector
smaller then c:.
bsdlabel -w ad0s2
bsdlabel -w ad2s2
bsdlabel -e ad0s2
bsdlabel -e ad2s2
gmirror label -v -b round-robin M1 ad0s2
gmirror configure -a M1
gmirror insert M1 ad2s2
This appears to work fine.
So then I move on to ad4 and ad6.
fdisk -I ad4
fdisk -I ad6
bsdlabel -w ad4s1
bsdlabel -w ad6s1
bsdlabel -e ad6s1
bsdlabel -e ad4s1
gmirror label -v -b round-robin M2 ad4s1
gmirror configure -a M2
gmirror insert M2 ad6s1
gmirror picks up ad6 as the provider instead of ad6s1.
I have also tried
fdisk -I ad4; fdisk -I ad6
gmirror label -v -b round-robin M2 ad4s1
bsdlabel -w /dev/mirror/M2
bsdlabel -e /dev/mirror/M2 # make a: on sector smaller then c:
gmirror configure -a M2
gmirror insert M2 ad6s1
Same results. ad6 is picked up a provider instead of ad6s1. What am I doing=
?
Seems like a meta-data problem. If I hardcode providers name with -h it wor=
ks
as expected.
Please enlighten me to my errorrs!
