** Summary changed: - Promise TX4310 Raid Controller without raid functionality + Promise TX4310 FakeRaid Controller without raid 5 functionality
** Description changed: - This controller is recognized and its disks can be listed but not - accessed; no raid functionality is given. The Linux Kernel version - 2.6.17 officially supports this raid controller. The Partial Open Source - Driver by Promise doesn't work with Linux 2.6 and later - maybe this - driver could be ported to Linux 2.6.17? + This fake-raid controller (software raid with HW XOR-engine) is + recognized and its disks are listed as /dev/sda to /dev/sdd. Raid 0 and + raid 1 setups are functional, but it's not possible to run a raid 5 + array. The official drivers by Promise don't work, the program "dmraid" + cannot activate the array, altough it finds the controller and the + disks: + + $ sudo dmraid -r + ERROR: pdc: identifying /dev/sda, magic_0: 0x52b33485/0x410522, magic_1: 0x52b33485/0x10680522, total_disks: 4 + ERROR: pdc: identifying /dev/sdb, magic_0: 0x52b33485/0x400522, magic_1: 0x52b33485/0x10680522, total_disks: 4 + ERROR: pdc: identifying /dev/sdc, magic_0: 0x52b33485/0x420522, magic_1: 0x52b33485/0x10680522, total_disks: 4 + ERROR: pdc: identifying /dev/sdd, magic_0: 0x52b33485/0x64d0522, magic_1: 0x52b33485/0x10680522, total_disks: 4 -- Promise TX4310 FakeRaid Controller without raid 5 functionality https://launchpad.net/bugs/67468 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
