I'm having an odd problem with a poweredge 1850, and it's driving me mad - google's not helped me, I've tried a few mailing lists, and I've run out of places to look, so any help would be greatly appreciated. Basically, I can't use fdisk on /dev/sda. I can however boot off this array, and everything is working fine - I'm having no issues using this array for anything else. A live, and apparently healthy system is running from it. # fdisk -l Unable to seek on /dev/sda # sfdisk /dev/sda --no-reread Disk /dev/sda: 35669 cylinders, 255 heads, 63 sectors/track llseek: Bad file descriptor sfdisk: seek error on /dev/sda - cannot seek to 0 /dev/sda: unrecognized partition table type Old situation: No partitions found The odd thing is, if I boot off a gentoo liveCD, everything's ok. I've tried various kernel versions of the 2.6 series. I've tried using config's found on google. I've tried configuing a kernel from scratch countless times. I've tried repartitioning and reinstalling from scratch. last bit of juice out of my CPUs or anything silly like that. make.conf CHOST="i686-pc-linux-gnu" CFLAGS="-march=nocona -O2 -fomit-frame-pointer -fforce-addr -ftracer -pipe" The array is configured as a single RAID 5 array with 3 disks. No dell software is installed yet. No dell patches (if there are any?) have been applied to the kernel. I've tried gentoo-sources, hardened-sources and standard kernel versions. extra info: # zcat /proc/config.gz | grep MEG CONFIG_MEGARAID_NEWGEN=y CONFIG_MEGARAID_MM=y CONFIG_MEGARAID_MAILBOX=y # CONFIG_MEGARAID_LEGACY is not set # CONFIG_MEGARAID_SAS is not set # lspci | grep RAID 02:0e.0 RAID bus controller: Dell PowerEdge Expandable RAID controller 4 (rev 06) Kind Regards, -- Ian P.
