Hi,
I'm unable to create a new LV on an existing VG with LVs.
I'm on
uname -rm
3.19.3-1.gf10e7fc-default x86_64
lvm version
LVM version: 2.02.98(2) (2012-10-15)
Library version: 1.03.01 (2011-10-15)
Driver version: 4.29.0
I have a VG with lots ov available space
vgs
VG #PV #LV #SN Attr VSize VFree
VG0 1 7 0 wz--n- 930.19g 855.19g
It's already got LVs on it
lvs
LV VG Attr LSize Pool Origin Data% Move Log Cpy%Sync Convert
LV_ROOT VG0 -wi-ao--- 20.00g
LV_HOME VG0 -wi-ao--- 40.00g
LV_SWAP VG0 -wi-ao--- 2.00g
...
Time's passed. Now, when I attempt to create a new LV on the VG, if fails with
lvcreate -L 30G -n LV_TEST /dev/VG0
/dev/md1: lseek 18446744071795900416 failed: Invalid argument
and in syslog I see

The VG's on a RAID1 array.

The RAID's healthy, the system boots, and I can see/use all the existing LVs on the VG/PV.
I just can't create new LVs anymore.
Any suggestions at to problem & fix?
