Hi, I have a following problem with LVM2. When I try to create snapshot logical volume, command
crashes with segmentation fault. Logic volume is somehow created, but I am not able to
mount it, because it complains that the device does not exist. >vgdisplay vol0 #
shows hom many PEs are available . . Free PE/ Size 6400
/ 100.00 GB >lvcreate –L 1280 –c 1024k –s –n
vol0.1 /dev/vol0/prj # produces: Segmentation fault >lvdisplay ---

created, BUT I am not able to mount it >mount /dev/vol0/vol0.1 /mnt Mount: special device /dev/vol0/vol0.1 does not exist #Well, I have removed the snapshot volume and created
just another logical volume in the same group >lvremove –f /dev/vol/vol0.1 Logical volume “vol0.1” successfully
removed >lvcreate –L 1280 –n vol0.1 vol0 Logical volume “vol0.1” created >mkfs.ext3 /dev/vol/vol0.1 >mount –t ext3 –o ro /dev/vol/vol0.1
/export/prj.1 # mounts the system >df –k . . /dev/mapper/vol0-vol0.1 ….. What am I doing wrong ? Any hints to follow ? I have following configuration: SuSE 9.2 ( 2.6.8-24-smp ) 3ware Raid controller lvm2-2.00.25-2 best regards premysl.vaclavik@ondemand.co.at |
