Hello list,
lvm autogrow grows more than allowed virtual size.
Kernel: 3.5-rc7
lvm/dmeventd: up2date git version 186a2772
I created my thin disk like this:
lvcreate --poolmetadatasize 5G -L 10G -T thinvol/pool1 -V 100G --name disk1
After some autoresizing lvs looks like this:
# lvs
LV VG Attr LSize Pool Origin Data% Move Log Copy% Convert
disk1 thinvol Vwi-a-tz 100,00g pool1 22,95
pool1 thinvol twi-a-tz 33,77g 67,97
When i copy constantly data to my device - i end up here:
# lvs
LV VG Attr LSize Pool Origin Data% Move Log Copy%
Convert
disk1 thinvol Vwi-aotz 100,00g pool1 99,96
pool1 thinvol twi-a-tz 123,86g 80,71
So the pool is bigger than disk1 and the 23,86GB will never get used as
the disk is FULL.
Is this expected?
