It would be good to add the tests for tool itself, sometimes we see something like :

# mount | grep ldiskfs
/dev/vdb on /mnt/lustre-mgs type lustre (ro,svname=MGS,nosvc,mgs,osd=osd-ldiskfs,user_xattr,errors=remount-ro)
/dev/vdc on /mnt/lustre-mds1 type lustre (ro,svname=lustre-MDT0000,mgsnode=192.168.101.5@tcp,osd=osd-ldiskfs,user_xattr,errors=remount-ro,user_xattr)
