We are converting from using devicemapper to thinpool on the last of our Docker Servers. I just cannot quiet confirm if we have sufficient disk space so that I may shrink the Logical Volume enough.
We have as follows :
# df -h
/dev/mapper/vgData-lvData1 187G 119G 68G 64% /data1
This contains generic data and all of the docker data … for docker it is as follows :
# du -hs
… more specifically :
Do I need a thinpool larger than 55G to be safe since devicemappper is 55G ?
