[linux-lvm] 2.4.0-test8 LVM(vgscan) on SCSI problems (report)

[iafilius]

Hello,

With 2.4.0-test8 (test8-pre6 seems to be OK) vgscan (at
boottime) "sees" al my volumegroups which are on IDE disk, but not those
on SCSI disk.
I had no problems mounting a "plain" ext2 scsi partition on same disk.


After some "research" i found sd.c is patched, but not yet in test8-pre6.

vgscan version:
sjoerd:~ # vgscan -h
Logical Volume Manager 0.8 by Heinz Mauelshagen  04/11/1999  (IOP 6)

lvm,scsi-disk compiled into the kernel, but mostly as modules.

Yes, if you look at /proc/partitions, you'll find that all scsi disks are
duplicated. This confuses LVM and it doesn't activate any VG that contains
partitons on SCSI drives. 

If you comment out the last two lines of sd.c (module_init....) LVM works
again. I don't know if this may cause other problems, but I'm just running
such a patched -test8 kernel.
