Subject: Drive missing only with LVM kernel
Date: Tue, 25 Jan 2005 21:30:09 +0100 [thread overview]
Message-ID: <1106685009.8968.15.camel@localhost> (raw)
Hiya,
I run a Linux 2.6.9 kernel with RAID and LVM on a combined total of six
ATA and SATA harddisks. 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<hdg1>
md: running: <sdb1><sda1><hdg1><hdc1><hda1>
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,

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.
