Hi folks,
I want to create a new RAID5-Volume on 4 new disks.
The Server is running with Solaris9 and all rec. Patches.
The Boot disk is setup as a Mirror without a second disk.
bash-2.05# metastat -p
d60 -m d61 1
d61 1 1 c0t0d0s6
d30 -m d31 1
d31 1 1 c0t0d0s3
d10 -m d11 1
d11 1 1 c0t0d0s1
d0 -m d1 1
d1 1 1 c0t0d0s0
bash-2.05# metadb
flags first blk block count
a m p luo 16 8192 /dev/dsk/c0t0d0s7
a p luo 8208 8192 /dev/dsk/c0t0d0s7
a p luo 16400 8192 /dev/dsk/c0t0d0s7
bash-2.05# more /etc/lvm/mddb.cf
#metadevice database location file do not hand edit
#driver minor_t daddr_t device id checksum
dad 7 16 id1,dad@AST320414A=3EC1942E/h -2212
dad 7 8208 id1,dad@AST320414A=3EC1942E/h -10404
dad 7 16400 id1,dad@AST320414A=3EC1942E/h -18596
bash-2.05# more /kernel/drv/md.conf
#
#pragma ident "@(#)md.conf 2.1 00/07/07 SMI"

# Begin MDD database info (do not edit)
mddb_bootlist1="dad:7:16:id1,dad@AST320414A=3EC1942E/h
dad:7:8208:id1,dad@AST320
414A=3EC1942E/h dad:7:16400:id1,dad@AST320414A=3EC1942E/h;
# End MDD database info (do not edit)
bash-2.05# grep md /etc/vfstab
/dev/md/dsk/d30 - - swap - no -
/dev/md/dsk/d0 /dev/md/rdsk/d0 / ufs 1 no -
/dev/md/dsk/d10 /dev/md/rdsk/d10 /var ufs 1 no -
/dev/md/dsk/d60 /dev/md/rdsk/d60 /export/home ufs 2 yes -
everything is fine
But now:
All new disks have a Layout like:
* /dev/rdsk/c3t0d0s2 partition map
*
* First Sector Last
* Partition Tag Flags Sector Count Sector Mount Directory
2 5 01 0 241246208 241246207
6 0 00 69632 241176576 241246207
7 0 00 0 69632 69631
If I want to create additional database replicas
the first is o.k.
bash-2.05# metadb -a -c 1 /dev/dsk/c3t2d0s7
# metadb
flags first blk block count
a m p luo 16 8192 /dev/dsk/c0t0d0s7
a p luo 8208 8192 /dev/dsk/c0t0d0s7
a p luo 16400 8192 /dev/dsk/c0t0d0s7
a u 16 8192 /dev/dsk/c3t2d0s7
but the second failed:
bash-2.05# metadb -a -c 1 /dev/dsk/c3t3d0s7
metadb: sun1: c3t3d0s7: overlaps with device in metadevice state database
or if I want to create the RAID-Volume:
bash-2.05# metainit d101 -r /dev/dsk/c3t0d0s6 /dev/dsk/c3t2d0s6
/dev/dsk/c3t3d0s6 /dev/dsk/c3t4d0s6
metainit: sun1: c3t2d0s6: overlaps with device in d101
But the disks are available, as single Volumes, without Problems!
Any hints?
TIA
Tobias
