Hi system : RH7.2, all erratas installed (like raidtools-0.90-24 and kernel-2.4.9-31) I got a RAID5, initially on hde1, hdg1, hdh1. Now I want to move the raid to another computer and use hdb1, hdc1 and hdd1 instead. I have browsed the mailinglist archive (http://marc.theaimsgroup.com/?l=linux-raid) and seen others with simular problems but I have still not solved the problem. I have altered /etc/raidtab to reflect the device changes and run the command # raidstart -c /etc/raidtab /dev/md0 My log then gives me messages like : kernel: (read) hdb1's sb offset: 22073152 [events: 00000023] modprobe: modprobe: Can't locate module block-major-33 kernel: md: could not lock [dev 21:01], zero-size? Marking faulty. It's obvious that linux still tries to access hde (block-major-33), hdg and hdh. Do I have to install mdadm and perform some magic stunts ? If so, does mdadm require any particular version of kernel/raidtools ? -- vidar - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
