I'm having trouble creating a striped logical volume across all 52 disks
in a volume group. This is what happens when I try to create the
logical volume:
# lvcreate -i52 -I4 -l450996 -n mydata data_volume
device-mapper ioctl cmd 9 failed: Invalid argument
Couldn't load device 'data_volume-mydata'.
Failed to activate new LV.
I see these two lines echoed to the console:
device-mapper: couldn't split parameters
device-mapper: error adding target to table
Here's the output for vgdisplay:
--- Volume group ---
VG Name data_volume
System ID
Format lvm2
Metadata Areas 52
Metadata Sequence No 1
VG Access read/write
VG Status resizable
MAX LV 256
Cur LV 0
Open LV 0
Max PV 256
Cur PV 52
Act PV 52
VG Size 1.72 TB
PE Size 4.00 MB
Total PE 450996
Alloc PE / Size 0 / 0
Free PE / Size 450996 / 1.72 TB
VG UUID kKlfs8-CWAA-zMg5-ELOm-GmI7-zOhx-KsXyAA
I reduced the number of disks in the stipe set by 4 drives (and the
logical volume size appropriately) until I could create a logical
volume with these parameters:
lvcreate -i12 -I4 -l104076 -n mydata data_volume
Any suggestions?
Thanks!
