Ultra slow disc access with software raid
I have a problem with Mandriva 2007 free as well as all other distributions (Red hat based, CentOS 4.4, Fedora 6 etc).
Setup I have tried
AMD XP 2600+ (32 bit)
2 * 200 Gb Sata discs
AMD XP 3200+ (64 bit)
2 * 250 GB Samsung SATA discs
The setup on both machines has been
sda1 /boot 100mb
sda2 Swap 2 Gb
sda3/md0 / 16 Gb
sda4/md1 /mnt/share 170Gb (larger on the 250 gb)
sdb1/md0 / 16 Gb
sdb2/md1 /mnt/share 170 Gb (larger on the 250 gb)
md0 is raid1 mirror
md1 is raid0
Installation often goes well all discs formatted etc. system installed.
But after reboot the system is so slow so after 4-5 hours the system has not finished booting. This error has occured on all distributions and two different machines and different discs.
No logs available of course since booting would take a week.
Does anyone know what's causing this?
