While booting /dev/hdg is recognised and even used by RAID: # dmesg |grep hdg ide3: BM-DMA at 0xdf98-0xdf9f, BIOS settings: hdg:pio, hdh:pio hdg: WDC WD2000JB-00EVA0, ATA DISK drive hdg: max request size: 1024KiB hdg: 390721968 sectors (200049 MB) w/8192KiB Cache, CHS=24321/255/63, UDMA(100) hdg: cache flushes supported md: adding hdg1 ... md: bind md: running: raid5: device hdg1 operational as raid disk 2 disk 2, o:1, dev:hdg1 As soon as the system had booted hdg has completely vanished, even in single user mode: # ls /dev/hd* /dev/sd* /dev/hda /dev/hda3 /dev/hdc1 /dev/hde /dev/hde3 /dev/sda2 /dev/sdb1 /dev/hda1 /dev/hda4 /dev/hdc2 /dev/hde1 /dev/sda /dev/sda3 /dev/sdb2 /dev/hda2 /dev/hdc /dev/hdc3 /dev/hde2 /dev/sda1 /dev/sdb /dev/sdb3 But the RAID is working just fine: # cat /proc/mdstat Personalities : [raid5] md0 : active raid5 sdb1[4] sda1[3] hdg1[2] hdc1[1] hda1[0] 97674240 blocks level 5, 256k chunk, algorithm 2 [5/5] [UUUUU] When I boot this same system with the same kernel without LVM appears just fine. As soon as I compile LVM in (even as not-yet-activated module) hdg is gone after booting. This beheavure also happens if I add this particular or a different drive to a different controller like /dev/hdb My full kernel config can be found at: http://www.morgana.net/~jasper/config-2.6.9 Any ideas how I can use LVM and this 6th drive? hda: 320173056 sectors (163928 MB) w/7936KiB Cache, CHS=19929/255/63, UDMA(100) hdc: 312581808 sectors (160041 MB) w/8192KiB Cache, CHS=19457/255/63, UDMA(100) hde: 398297088 sectors (203928 MB) w/8192KiB Cache, CHS=24792/255/63, UDMA(100) hdg: 390721968 sectors (200049 MB) w/8192KiB Cache, CHS=24321/255/63, UDMA(100) ata1: dev 0 ATA, max UDMA/100, 488397168 sectors: lba48 ata2: dev 0 ATA, max UDMA/100, 488397168 sectors: lba48 Kind regards, Jasper. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
