Hi,
The following command creates a logical volume in vgtest with EXTENT-BASED MIRRORED STRIPES:
lvcreate -D y -s g -m 1 -l 5 /dev/vgtest
The distributed allocation proceeds as follows:
├В┬╖ A free extent is allocated from the 1st pvol in pvg1.
├В┬╖ A free extent is allocated from the 2nd pvol in pvg1.
├В┬╖ A free extent is allocated from the 1st pvol in pvg1.
├В┬╖ A free extent is allocated from the 2nd pvol in pvg1.
├В┬╖ A free extent is allocated from the 1st pvol in pvg1.
├В┬╖ Mirrors for the five extents are then allocated from the free extents in pvg2 in a similar manner.
Create a logical volume of size 90 MB striped across 3 disks with a stripe size of 64 KB:
lvcreate -L 90 -i 3 -I 64 /dev/vg03
Create a logical volume of size 90 MB striped across 3 disks with one mirror copy and a stripe size of 64
KB:
lvcreate -L 90 -i 3 -I 64 -m 1 /dev/vg03
