I did my test on my custom 2.6.16-rc4-mm1 kernel, in which I compiled my silicon image 680 raid card driver as a module, and moved it out of the /lib/modules/... tree so that I can # insmod siimage.ko at will after booting. (You can't rmmod it at will, once inserted, that driver is marked [permanant] in lsmod (have to reboot to get rid of it). That way, I can avoid the seek errors in the initrd. Another way to avoid them is the kernel command line parameter hde=noprobe, however, dmraid will not work after that because /sys/block/hde is not created. I agree with you that it would be nice if the kernel initialization of the hard disk driver caused only the creation of /sys/block/hde, and didn't mention anything about partitions. However, that does not generate an annoying repetative error like a normal partition scan would. Why would the internal nash mount command be scanning if not using a volume label or when using a filesystem type of proc or ext3? > > -- > Peter > > _______________________________________________ > Ataraid-list mailing list > [email protected] > https://www.redhat.com/mailman/listinfo/ataraid-list > -- _______________________________________________ Search for businesses by name, location, or phone number. -Lycos Yellow Pages http://r.lycos.com/r/yp_emailfooter/http://yellowpages.lycos.com/default.asp?SRC=lycos10
