I have seen an experimental linux box where
lvreduce -rL -10G /dev/main/repository
worked without unmounting (i.e. even on root,home dir etc), but it does not on my server install
- debian squeeze
- LVM version: 2.02.111(2) (2014-09-01)
- Library version: 1.02.90 (2014-09-01)
- Driver version: 4.27.0
- Linux kernel: 3.16.0-4-amd64
- filesystem: ext3
what it the version combination which allows it?
PS: I tried to browse release notes of lvm but to no avail.
