I=20 really shouldn=B4t do that, because Linux crashed and after a hard reboot= =20 it could not boot any more. It stopped during the execution of the=20 init-scripts and i was not able to do anything, thus: 2nd hard reboot. I=20 have another(old) gentoo installation on my computer and this time I=20 booted into that one. By accident I realized that one of the discs of my=20 raid system has been marked as faulty and it was syncing in the=20 background. /proc/mdstat said that it would need 20min or so, but after=20 15min it said 200min! After another 10min it was sth >300min (and a lot=20 of IO errors). So I rebooted again, this time it synced successfully in=20 12min. Then it was possible to boot and work with my normal system=20 without any further difficulties or IO errors. Summing up, I can say: + I successfully wrecked my file system, but software raid was able to=20 repair it - without a second Linux-installation on another partition, you=B4re lost - restoring of a faulty raid disk is not reliable - it seems that it is not possible to boot or work with a system, whose=20 system disk is being restored at the same time (Linux-2.6.12.6) --=20 gentoo-amd64@gentoo.org mailing list
