LVM problem creating a raid 5 logical volume
 

Hi, im really new with all LVM stuff, and im trying to execute this command "lvcreate --type raid5 -i 2 -L 100M -n raid_lv grupo3"
but the output is

Using default stripesize 64,00 KiB.
Rounding size 100,00 MiB (25 extents) up to stripe boundary size 104,00 MiB (26 extents).
Insufficient suitable allocatable extents for logical volume raid_lv: 28 more required

I cant figure it out how to fix it, i have checked the alloc of the volume group and every group of logical volumes are "normal"

I could use a hand, i really need it for a school project.

Have you, in your class, studied how many devices are required for RAID 5 creation? Have you really looked at that output and considered if the extents it is attempting are actually available? Have you tried adjusting the command in any way?

Thank you

You are welcome, but I would like to know what you tried and if it worked or not. Can you illuminate us?

Im doing a final project from school, and all i wanted to do was to show how this command works. I just created a raid5 logical volume to show the syntaxis reflected on my virtual machine.
