Re: [Xen-users] Xen with LVM
Quoting "IDAGroup - R.W.Muller" <robin@xxxxxxxxxxx>:
Hello Errol, I tried that and get a little weird partition table:
sfdisk -l -uS /dev/vms/centos5_data
Disk /dev/vms/centos5_data: 0 cylinders, 0 heads, 0 sectors/track
Warning: The partition table looks like it was made
for C/H/S=*/255/63 (instead of 0/0/0).
For this listing I'll assume that geometry.
Units = sectors of 512 bytes, counting from 0
Device Boot Start End #sectors Id System
/dev/vms/centos5_data1 * 63 3068414 3068352 83 Linux
/dev/vms/centos5_data2 0 - 0 0 Empty
/dev/vms/centos5_data3 0 - 0 0 Empty
/dev/vms/centos5_data4 0 - 0 0 Empty
I wouldn't worry too much about that. sfdisk is probably just
confused. Since the file doesn't have a ioctl, that would be my guess
Now I just have to find out, how I can get ride of the Empty partitions
and how to use snapshot for backup and I'm getting closer
to a usable result :)
lvcreate -L1G -n vmsnap /dev/vms/centos5_data
Then mount it as above. Keep in mind that for snapshots, all changes
to the live volume are written to the COW table on the snapshot
volume. Make sure you allocate enough space for this.
