I started this morning with RAID :-) 20 minutes later I had a raid device running as nitwit, compliments,compliments. I got greedy, and wanted to create a 3-disk raid0 device to install redhat on, and the first problems turned up. 1 I started by modifying redhat bootdisk with a MD0 capable 2.2.5 kernel. 2 Booted from it (bootdisk, the rescue-root disk) 3 mounted the only partition in the machine not to become part of the raid (the future swap part.), installed some raid tools on them. 0.9 btw. 4 mknod /dev/md0 b 9 0 5 chmod 600 /dev/md0 6 raidttab to /etc/raidtab, containing the standard raid0 example expanded to 3 disks. (p.s. the errormessage if you try to create a three disc array with number 0,1,1 is a bit cryptic, took me 30 minutes before I figured it out) 7 /mnt/image/mkraid /dev/md0 --really.force 5 sec warning message, and then the following message (which I couldn't pipe, because of bootdisk bash?) roughly retyped: Handling md device md0 analysing superblock disk 0: /dev/hda1 xxxk superblock at (xxx-12)k disk 1: /dev/hdc1 disk 2: /dev/hdd1 bind<hda1,1> bind<hdc1,2> bind<hdd1,3> hdd1's event counter 00000000 hdd1's event counter 00000000 hdd1's event counter 00000000 md: md0: raid array is not clean -- starting background reconstruction: unbind (hda1,1) export_rdev(hda1) unbind (hdc1,2) export_rdev(hda1) unbind (hdd1,3) export_rdev(hda1) md0 stopped /dev/md0 no such device --- Remarks: 1 hdc1 and hdd1 were used to create the first experimental raiddevice. Both partitions were removed, recreated and mke2fs'ed to avoid problems. 2 Watch the bind and unbind calls. This is no typo. The numbers for the unbind calls are 1 higher than the bind calls. Any suggestions????? (p.s. mail to me directly, or how does subscribing work for this list?) Marco van de Voort ([EMAIL PROTECTED]) <http://www.stack.nl/~marcov/xtdlib.htm>
