hi ya patrick
yeah... raidhotadd .... i just am too lazy to go look up
the latest commands... keeps changing :-)
and new ones added each year ...
( nope, i dont use them commands too often so far )
if you can do your raidhotadd and it works ??
cat /proc/mdstat --> what does it say
write a huge 3GB file to the raid array, take it down
and see if the 3GB is corrupt etc..
- lots o testing ...
- donno why it wont "stick" -- maybe something
wrong with /etc/raidtab or wrong partition type
for /dev/hdg ??? ( should be fd ( raid autodetect )
or something like it ( fdisk, cfdsisk, ... )
- if its based on bios, hw raid.... ignore everything
in here ... bios hw raid doesnt work ... and doesnt
need any of these commands/files
- reboot with only one disk for a good test..
