LVM cant find harddisk

[chris911]

Hi,
I got the following issue with lvm2 on debian sarge:
I reinstalled my OS, and now I can't recreate my volumegroup. The BIOS can see both IDE drives, as can the kernel(messages in kern.log). Also, entering a:
>>pvdisplay /dev/hda
gives the following output:
PV Name /dev/hda
VG Name media_volume
PV Size 189.92 GB / not usable 0
Allocatable yes (but full)
PE Size (KByte) 4096
Total PE 48620
Free PE 0
Allocated PE 48620
PV UUID TV7Agb-qt5j-7nEv-JiQc-cMFD-6z5O-7oxg41

But - a single pvdisplay command shows:
Couldn't find device with uuid 'TV7Agb-qt5j-7nEv-JiQc-cMFD-6z5O-7oxg41'.
--- Physical volume ---
PV Name unknown device
VG Name media_volume
PV Size 189.92 GB / not usable 0
Allocatable yes (but full)
PE Size (KByte) 4096
Total PE 48620
Free PE 0
Allocated PE 48620
PV UUID TV7Agb-qt5j-7nEv-JiQc-cMFD-6z5O-7oxg41

--- Physical volume ---
PV Name /dev/hdb
VG Name media_volume
PV Size 233.76 GB / not usable 0
Allocatable yes
PE Size (KByte) 4096
Total PE 59843
Free PE 236
Allocated PE 59607
PV UUID oEwnmJ-uOqG-tzmQ-7Qu2-pMio-6NmT-BVvY2y

...but this "unknown device" is /dev/hda, which exists and is accessible. when I try to create the volume, it fails with the error that the drive with the device id of hda is not found

Any help appreciated!!!
Thanks in advance,
Chris

Hello
Linux uses /dev/hda or /dev/sda is stead of volume names like windows
windows has C:/ for the root dir
linux has / for the root
If you are looking to give a volume name it is not going to work.

here is a common fstab file
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/hda1 / ext3 defaults,errors=remount-ro 0 1
/dev/hda6 /home ext3 defaults 0 2
/dev/hda5 none swap sw 0 0
/dev/hdc /media/cdrom0 udf,iso9660 user,noauto 0 0
/dev/sda1 /media/usb0 vfat rw,user, 0 0
hope this helps.
