[linux-lvm] Adding to vg broke it :-(

[lvmlist@spltd.f9.co.uk]

Hi all,

It seems I'm up to my neck in it again :-(

Briefly, I ran out of space on my LVM mounted /home partition but as I
have 1.5GB space free on another disk I thought I'd add that to my
volume group and increase the size of /home. All seemed to go OK until
reboot upon which my system can only mount / (which is independent of
LVM). It appears that /etc/lvmtab /etc/lvmtab.d have all been deleted
hence why it can't find LVG "system".
/etc/lvmtab exists but is empty.
/etc/lvmtab.d/ exists but is empty.
/etc/lvmconf/ exists & contains system.conf.1.old and system.conf
(newest).

System is SuSE 8.0 Pro. on i386
Harddisks: 2 scsi mounted as

/dev/sdb1        swap
/dev/sdb2        /
/dev/sdb3        LVM

/dev/system/home /home
/dev/system/usr  /usr
/dev/system/var  /var

sda had an old installation of SuSE on it is
 presently unused (and half the size of sdb).

Any guidance as to where to go from here would
be appreciated pls.

Thanks,

Mark Pearson.
