Linux-LVM-Bug at sistina.com, as told in the README, doesn't work so I send
it here instead.
I'm not on the list so please CC wigren at home.se!
I created a VG with only /dev/hdd1. Then I try to extend that VG with
/dev/hdc1, but lvextend segfaults.
Still, vgdisplay says it's there, but "VG Size: 42.95 GB", which is the
size of /dev/hdd1 ONLY.... /dev/hdc1 is 29 GB so it should say "72
GB"...
They trying to remove /dev/hdc1 from the VG it says it doesn't belong to
VG??!!!
Please help!
I think this is best explained with an example:
stormie:/usr/src/temp/LVM/0.9.1_beta3# vgextend -v vg02 /dev/hdc1
vgextend -- locking logical volume manager
vgextend -- checking volume group name "vg02"
vgextend -- checking volume group "vg02" existence
vgextend -- checking for inactivity of volume group
vgextend -- reading data of volume group "vg02" from lvmtab
vgextend -- INFO: maximum logical volume size is 255.99 Gigabyte
vgextend -- reading data for all physical volumes from disk(s)
vgextend -- extending VGDA structures of volume group "vg02"
vgextend -- volume group "vg02" will be extended by 1 new physical
volumes
vgextend -- extending volume group "vg02" by physical volume "/dev/hdc1"

I use kernel 2.4.0ac12 and 0.9.1beta3 of the lvm-tools.
