I am running kernel 2.4.9-64, but this problem also occurs with 2.4.17-64-smp and non-smp, and 2.4.18-64-smp and non-smp. When I attempt to make a software RAID0 array on 3 1Gb partitions on 3 18.2gb internal SCSI disks, I get this error: hypo:~# mkraid /dev/md0 handling MD device /dev/md0 analyzing super-block disk 0: /dev/sdb1, 976880kB, raid superblock at 976768kB disk 1: /dev/sdc1, 976880kB, raid superblock at 976768kB disk 2: /dev/sdd1, 976880kB, raid superblock at 976768kB mkraid: aborted, see the syslog and /proc/mdstat for potential clues. Syslog says: hypo:~# tail /var/log/syslog Apr 30 05:36:34 hypo kernel: sys32_ioctl: Unknown cmd fd(3) cmd(400c0910) arg(00028a44) Apr 30 05:36:34 hypo kernel: sys32_ioctl: Unknown cmd fd(4) cmd(400c0910) arg(bff00350) Apr 30 05:36:34 hypo kernel: sys32_ioctl: Unknown cmd fd(4) cmd(80480923) arg(00029390) /proc/mdstat says: hypo:~# cat /proc/mdstat Personalities : [raid0] read_ahead not set unused devices: I've had a look through the archives and found a few posts about 32-bit to 64-bit IOCTLs but nothing seemed to specifically mention the RAID stuff. I also had a look in arch/parisc/kernel/ioctl32.c and there were a couple of lines commented out with comments like "new RAID code is half merged". Is RAID on 64-bit PA-RISC a work in progress? Also, I have noticed that the 2nd CPU in the L2000 is always disabled when I boot with a SMP kernel, errors like SMP: CPU3 is stuck appear near the start of bootup. (Sorry I don't have any more detail on these, but I can provide it if needed) Any ideas/help would be greatly appreciated. I can provide more details if needed. Cheers, James BTW: Great job on the port to PA-RISC :) -----BEGIN PGP SIGNATURE----- Version: PGP 7.1.1 iQA/AwUBPM4yo1W+bhIOiSqWEQJSZQCguc5h0mrXQ7pD352VuLeZDeSJ7PkAnjdl P8k6Y/oUEcFa8kS95ISO+xQz =2axk -----END PGP SIGNATURE-----
