lvm und promise fasttrack
Hallo Heinz,
ich hab schon wieder ein "Problem".
Auf meinem Mainboard ist ein Promise Fasttrack 100 Controller. Die Festplatten kann ich �ber /dev/hd[e-h] ansprechen.
Es gibt aber auch die M�glichkeit das Hardware Raid anzuspechen �ber /dev/ataraid/d[0-2]px , mit x als Partitionsnummer.
Beim Aufruf von vgcreate passiert folgendes :
vgcreate gl_lvm /dev/ataraid/d0p1
vgcreate -- physical volume name "/dev/ataraid/d0p1" is invalid
Gr��e,
Jens

My mainboard features a Promise Fasttrack 100 Controller, and I can access my harddrives as /dev/hd[e-h]

But there is also the option to use the hardware raid as /dev/ataraid/d[0-2]px, with x beeing the partition number

when calling vgcreate like this:
vgcreategl_lvm/dev/ataraid/d0p1
vgcreate -- physical volume name "/dev/ataraid/d0p1" is invalid
For this to work, you must first use pvcreate to add the LVM's PV information to your device:
pvcreate /dev/ataraid/d0p1
But this will not help you, as pvcreate checls the device name against a list of valid devices, and /dev/ataraid is not port of this (at last not in the way outdated 0.9.1beta5 src I've on this system)
OOTH you should not trust the bios based softraid of any of the consumer raid devices, it is no hardware raid (not just MHO). If you want to do raid with IDE devices, I'd suggest using the kernel based MD drivers, and putting every IDE disk on it's own channel.

Yes, but if Jens still wants it, "atatraid" needs to be added to the _devdir array in lvm_dir_cache.c.
In future LVM you just change/add an entry to a central config file.
