Hello All , In an attempt to verify that the system would continue to function with only one drive in a 2 drive raid1 I removed a drive while the system was up . The system had no problem continuing to function . I shutdown and powered off in order to re-insert the drive (no need tempting fate another time) . Though on reboot the kernel would hang just after printing out: 'CPU0: Intel Pentium III (Coppermine) stepping 0a' and some odd CPU0 ... values on the next line . This is an SMP board , but no second cpu & the kernel is not smp . So I booted into a standalone CD with some tools , ie: mdadm . I then manually hotadded the missing partition back into the array and made sure it had completed the rebuild for both md's . I even fsck'd the md's which were flawless . Now when I boot the kernel it hangs -hard- at: Partition check: sda: There is no keyboard response on the screen for even sysrq . If I then again boot into the standalone CD I find that the array's need to resync . But we have never gotten anywhere near re-mounting the md's or even checking them afaics . Help . (please see email 'subject: linux-raid fatal: duplicate geometry' for hard details) Tia , JimL +------------------------------------------------------------------+ | James W.
