What I want to do is to reduce /home from 50G and extend /srv of 50G.
Are the following operations safe for this ? :

#> lvreduce -L-50G /dev/mapper/vg0-home
#> lvextend -L+50G /dev/mapper/vg0-srv
#> resize2fs /dev/mapper/vg0-srv
#> mount /home
#> mount /srv

assuming that /dev/mapper/vg0-home is 100G yes, else the option to
resize2fs should be the size of /dev/mapper/vg0-home minus 50G.
and you would probably have to fsck vg0-home and vg0-srv after
unmounting.

Another question I wondered is : what's the difference between lvreduce/lvextend and lvresize ?

i think these are 2 interfaces to the same funcrionality.
