Hello All , I am having a dickens of a time with preparing this system
to replace my present one .
I created a raid6 array over 6 147GB scsi drives .
steps I followed were .
fdisk /dev/sd[c-h] ( one at a time of course )
created a partition starting at cyl 2 & -10 Cyls from the end of the drive .
typed the partion FD
w
repeat until all six drives partitioned .
mdadm --create /dev/md3 --chunk=64 --metadata=1.2 --verbose --bitmap=internal --level=6 --raid-devices=6 --spare-devices=0 /dev/sd[cdefgh]1
Built just fine .
mkfs.ext3 -c -b 4096 -j -L HOME -R stride=96 /dev/md3
Again no problems noted .
reboot .
Array does not get reassembled , Here is the snippit out of a reboot .
