Hi all, I'm trying to migrate a RAID 1+0 array on a Promise S150 TX4 card with 2.4.x kernel and the ft3xx.o module to a 2.6 kernel based system. Unfortunately, it seems that dmraid supports only either RAID 1 or RAID 0, but not the combination (RAID 10) on this card. The ft3xx module gives the following information on the array: # cat /proc/scsi/ft3xx/0 PROMISE FastTrak TX4000/376/378/S150 TX Series Linux Driver Version 1.00.0.18 Adapter1 - FastTrak S150 TX4 Array - Array[1] : 2X2 Mirror/Stripe (OK-Gigabyte Boundary) Drive - 1 : Maxtor 6Y200M0 IDE1/Master 203928MB IRQ(17) UDMA6 Array[1] 3 : Maxtor 6Y200M0 IDE2/Master 203928MB IRQ(17) UDMA6 Array[1] 5 : Maxtor 6Y200M0 IDE3/Master 203928MB IRQ(17) UDMA6 Array[1] 7 : Maxtor 6Y200M0 IDE4/Master 203928MB IRQ(17) UDMA6 Array[1] Dmraid tells the following: # dmraid -tay pdc_cebbhcjedc: 0 792968704 mirror core 2 512 nosync 4 /dev/sdc 0 /dev/sdd 0 /dev/sde 0 /dev/sdf 0 ERROR: dos: reading /dev/mapper/pdc_cebbhcjedc[No such file or directory] Contratry to above the device file /dev/mapper/pdc_cebbhcjedc exists, but mounting it fails. Is there anything I could do to help get the RAID 10 support on TX4 to work with dmraid? All the best, Teemu _______________________________________________ Ataraid-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ataraid-list
