RAID 5 System Hard drive size problems.
Posted on 2006-11-06
Im having some slight issues with a RAID 5 system.
ive got 3 hardrives, all of them Hitachi 72.8 Gb running on a RAID 5, now one of them went down the other day. No problem i thought as ive got another 3 spare for just an emergency.
So i grab another brand new, unopened, HP Nec 72.8 Gb Hd, pop it in the server and prepare to select rebuild.
But then when i try the software gives me an error saying the HD isnt the same size, ie 72 and reports it as a 69Gb in the software. Whereas the current Hitachi 72 ones report theyre at 70 Gb.
i know theres always some size loss depending on HD size but this is stopping me from rebuilding my RAID 5 system when i know that the HD sizes are identical.
Does anyone know a way around this if any? I know if i put a 147 Gb HD in there it'll rebuild fine.
