Raid 0+1 is currently unsupported by the pdcraid driver; Raid 0 should work though. Could you please attach the output of "dmesg" so that I perhaps see what is wrong ? Also please try the 2.4.9-7 security update kernel as that has a newer version of the pdcraid driver... Have installed 2.4.9-7 and testing as follows 4 hdds's now available under the following configs test 1 raid 0+1 test 2 raid 0 for the first drive pair ide0 master, ide1 master raid 0 for the second drive pair ide1 slave, ide1 slave results test 1 mounting of raid 0+1 array correctly performed /dev/ataraid/d0p1 test 2 mounting of first raid 0 array correctly performed /dev/ataraid/d0p1 mounting of second raid 0 array correctly performd /dev/ataraid/d1p1 error testing test 1 loss of any disk in the raid 0+1 array results in entire array being offline test 2 loss of a single disk in the raid 0 array results in the array being offline yet still accessable by mounting through /dev/hd[e-h]* I'm suprised raid1+0 works as I didn't add any code for it. The "raid0 fails when you loose a drive" is hardly surprising.... Sorry brain slip Test 2 should read raid 1 array not raid 0 array with loss of one diskk in the mirror for error testing we are trying to install a number of rack mounted, 1U systems. on-board Promise FastTrack100, 2 disks. chosen raid1 over both HDs. no further HDs, so we'd like to make root part on the raid1. using bootnet.img+updates-disk-20020117.img, the kernel sees 2 HDs AND 1 raid1, but anaconda don't propose the raid as an option for partitioning/installation. I suppose that I have somehow to tell anaconda to use /dev/ataraid/dXpY I forgot to mention that of course bootnet.img comes from redhat-updates/7.2/en/os/images/i386/: -rw-rw-r-- 1 731 1474560 Jan 18 00:57 bootnet.img -rw-rw-r-- 1 731 1474560 Jan 18 00:57 pcmcia.img -rw-rw-r-- 1 731 1474560 Jan 18 00:57 update-disk-20020117.img -rw-rw-r-- 1 731 1474560 Oct 22 03:29 update-disk-20011009.img best regards Thanks for the bug report.
