Hi HPT374 controller with four disks attached. Two disks are in RAID0, two are in RAID1. Works fine under Windows, but dmraid gets something wrong, linux reports error and doesn't see partitions on mirrored set. Both disks have a standard DOS partition table, and all partitions are FAT32 or ext2fs partitions. An error is shown when running dmraid: ERROR: dos: reading /dev/mapper/hpt45x_bbdfhdjicg[2] Following is output from dmraid, I've tried to snip out irrelevant parts. # dmraid -a y -vvv -ddd <snip> NOTICE: skipping removable device /dev/hdc NOTICE: /dev/hde: hpt37x discovering NOTICE: /dev/hde: hpt37x metadata discovered NOTICE: /dev/hde: hpt45x discovering <snip> NOTICE: /dev/hdg: hpt37x discovering NOTICE: /dev/hdg: hpt45x discovering NOTICE: /dev/hdg: hpt45x metadata discovered <snip> NOTICE: /dev/hdi: hpt37x discovering NOTICE: /dev/hdi: hpt37x metadata discovered NOTICE: /dev/hdi: hpt45x discovering <snip> NOTICE: /dev/hdk: hpt37x discovering NOTICE: /dev/hdk: hpt45x discovering NOTICE: /dev/hdk: hpt45x metadata discovered <snip> DEBUG: _find_set: searching hpt37x_ehgjaggaf DEBUG: _find_set: not found hpt37x_ehgjaggaf DEBUG: _find_set: searching hpt37x_ehgjaggaf DEBUG: _find_set: not found hpt37x_ehgjaggaf NOTICE: added /dev/hde to RAID set "hpt37x_ehgjaggaf" DEBUG: _find_set: searching hpt45x_bbdfhdjicg DEBUG: _find_set: searching hpt45x_bbdfhdjicg DEBUG: _find_set: not found hpt45x_bbdfhdjicg DEBUG: _find_set: not found hpt45x_bbdfhdjicg DEBUG: _find_set: searching hpt45x_bbdfhdjicg DEBUG: _find_set: not found hpt45x_bbdfhdjicg NOTICE: added /dev/hdg to RAID set "hpt45x_bbdfhdjicg" DEBUG: _find_set: searching hpt37x_ehgjaggaf DEBUG: _find_set: found hpt37x_ehgjaggaf DEBUG: _find_set: searching hpt37x_ehgjaggaf DEBUG: _find_set: found hpt37x_ehgjaggaf NOTICE: added /dev/hdi to RAID set "hpt37x_ehgjaggaf" DEBUG: _find_set: searching hpt45x_bbdfhdjicg DEBUG: _find_set: found hpt45x_bbdfhdjicg DEBUG: _find_set: searching hpt45x_bbdfhdjicg DEBUG: _find_set: found hpt45x_bbdfhdjicg NOTICE: added /dev/hdk to RAID set "hpt45x_bbdfhdjicg" DEBUG: checking hpt37x device "/dev/hdi" DEBUG: checking hpt37x device "/dev/hde" DEBUG: set status of set "hpt37x_ehgjaggaf" to 16 DEBUG: checking hpt45x device "/dev/hdg" DEBUG: checking hpt45x device "/dev/hdk" DEBUG: set status of set "hpt45x_bbdfhdjicg" to 16 INFO: Activated striped RAID set "hpt37x_ehgjaggaf" NOTICE: discovering partitions on "hpt37x_ehgjaggaf" NOTICE: /dev/mapper/hpt37x_ehgjaggaf: dos discovering NOTICE: /dev/mapper/hpt37x_ehgjaggaf: dos metadata discovered DEBUG: _find_set: searching hpt37x_ehgjaggaf1 DEBUG: _find_set: not found hpt37x_ehgjaggaf1 DEBUG: _find_set: searching hpt37x_ehgjaggaf5 DEBUG: _find_set: not found hpt37x_ehgjaggaf5 DEBUG: _find_set: searching hpt37x_ehgjaggaf6 DEBUG: _find_set: not found hpt37x_ehgjaggaf6 DEBUG: _find_set: searching hpt37x_ehgjaggaf7 DEBUG: _find_set: not found hpt37x_ehgjaggaf7 NOTICE: created partitioned RAID set(s) for /dev/mapper/hpt37x_ehgjaggaf NOTICE: discovering partitions on "hpt45x_bbdfhdjicg" NOTICE: /dev/mapper/hpt45x_bbdfhdjicg: dos discovering ERROR: dos: reading /dev/mapper/hpt45x_bbdfhdjicg[2] INFO: Activated partition RAID set "hpt37x_ehgjaggaf1" INFO: Activated partition RAID set "hpt37x_ehgjaggaf5" INFO: Activated partition RAID set "hpt37x_ehgjaggaf6" INFO: Activated partition RAID set "hpt37x_ehgjaggaf7" <snip> DEBUG: freeing devices of RAID set "hpt37x_ehgjaggaf" DEBUG: freeing device "hpt37x_ehgjaggaf", path "/dev/hdi" DEBUG: freeing device "hpt37x_ehgjaggaf", path "/dev/hde" DEBUG: freeing devices of RAID set "hpt45x_bbdfhdjicg" DEBUG: freeing device "hpt45x_bbdfhdjicg", path "/dev/hdg" DEBUG: freeing device "hpt45x_bbdfhdjicg", path "/dev/hdk" DEBUG: freeing devices of RAID set "hpt37x_ehgjaggaf1" DEBUG: freeing device "hpt37x_ehgjaggaf1", path "/dev/mapper/hpt37x_ehgjaggaf" DEBUG: freeing devices of RAID set "hpt37x_ehgjaggaf5" DEBUG: freeing device "hpt37x_ehgjaggaf5", path "/dev/mapper/hpt37x_ehgjaggaf" DEBUG: freeing devices of RAID set "hpt37x_ehgjaggaf6" DEBUG: freeing device "hpt37x_ehgjaggaf6", path "/dev/mapper/hpt37x_ehgjaggaf" DEBUG: freeing devices of RAID set "hpt37x_ehgjaggaf7" DEBUG: freeing device "hpt37x_ehgjaggaf7", path "/dev/mapper/hpt37x_ehgjaggaf" # dmraid -s *** Set name : hpt37x_ehgjaggaf size : 312710912 stride : 128 type : striped status : ok subsets: 0 devs : 2 spares : 0 *** Set name : hpt45x_bbdfhdjicg size : 78150739 stride : 0 type : mirror status : ok subsets: 0 devs : 2 spares : 0 # ls -1 /dev/mapper # Notice no partitions from RAID1 control hpt37x_ehgjaggaf hpt37x_ehgjaggaf1 hpt37x_ehgjaggaf5 hpt37x_ehgjaggaf6 hpt37x_ehgjaggaf7 hpt45x_bbdfhdjicg Stuff displayed during POST: HPT374 BIOS Setting Utility v3.01 Channel Device Name Array Name Capacity (GB) Mode 1:Master MAXTOR 6L080L4 System 80.05 ATA/133 1:Slave No Device 2:Master ST380021A Data 80.02 ATA/100 2:Slave No Device 3:Master MAXTOR 6L080L4 System 80.05 ATA/133 3:Slave No Device 4:Master MAXTOR 6L080L4 Data 80.05 ATA/133 4:Slave No Device
