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?
