tests: lowering disc usage
Correction for aux test result ([] -> if;then;fi)
Use issue_discard to lower memory demands on discardable test devices Use large devices directly through prepare_pvs
I'm still observing more then 0.5G of data usage through.
Particullary:
'lvcreate' followed by 'lvconvert' (which doesn't yet support --nosync option) is quite demanging, and resume returns quite 'late' when a lot of data has been already written on PV. --- test/shell/lvcreate-large-raid.sh | 59 ++++++++++++++++-------------------- 1 files changed, 26 insertions(+), 33 deletions(-)
