Hi,

we are using a VMWare guest SLES11.3 x86\_64 and try to use LVM with ext3 as a datastore.

The problem is that the LVM VolGroup do not show up in /dev

We can see the vm devices in fdisk and created a volgroup to add the disks.

But the VolGoup will not be mapped to /dev/ORAPOOL but we do not understand why

lboptb01:/dev # pvs  
PV VG Fmt Attr PSize PFree  
/dev/sdb1 ORAPOOL lvm2 a-- 60.00g 0  
/dev/sdc1 ORAPOOL lvm2 a-- 20.00g 0  
/dev/sdd1 ORAPOOL lvm2 a-- 10.00g 0

lboptb01:/dev # lvs  
LV VG Attr LSize Pool Origin Data% Move Log Copy% Convert  
u01 ORAPOOL -wi------ 89.99g

lboptb01:/dev # lvdisplay  
— Logical volume —  
LV Name /dev/ORAPOOL/u01  
VG Name ORAPOOL  
LV UUID Y0Bwrl-i410-7cEn-nUK2-nu4G-Nqqr-ZUNzhy  
LV Write Access read/write  
LV Creation host, time lboptb01, 2014-04-24 14:17:40 +0200  
LV Status NOT available  
LV Size 89.99 GiB  
Current LE 23037  
Segments 3  
Allocation inherit  
Read ahead sectors auto

Thanks for advice

Did you try “vgchange -ay ORAPOOL”?

Re,

thank´s that solve my problem but why I do have to activate the pool by hand or script after every reboot ?

Does LVM or DM can do it on reboot ?
