Hello all, I'm new to the list. I'm having trouble installing RH7.2 on my 4-disk 0+1 array, with almost identical issues as Vincent Wu's. Here is a link to his article, for comparison: https://listman.redhat.com/pipermail/ataraid-list/2002-May/000791.html The main difference between my situation and his is that I'm trying to make my array bootable, whereas I don't think he was. In either case, the FastTrack BIOS is working properly, since it used to run a mirrored set on another server I had. Basically, when I try to write partitions to the /dev/ataraid/d0 array (which is properly recognised by modprobe and fdisk), I get the following error message: =================================== Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. WARNING: Re-reading the partition table failed with error 22: Invalid argument. The kernel still uses the old table. The new table will be used at the next reboot. Syncing disks. ================================= What does error 22 signify? I haven't found any information on this particular error code in a solid hour of searching man pages and search engines. I doubt that my partition structure is too complex, as I even tried to set the whole thing up in one primary partition. Any help is appreciated. TIA. -Marc --------------------------- Here is hardware information about my system: 4U RM case w/337W PS ASUS CUV4X MB Celeron 667MHz S370 CPU 256MB PC133 SDRAM (x1) 52X ATAPI CD-ROM 1.44 FDD 3COM 3C905TX-M NIC ATI 3D Rage IIC 4MB AGP Video Card Promise FastTrack66 ATA RAID Controller (configured for 0+1) Maxtor ATA133 7200RPM 80GB HDD (x4) (tested and working)
