Description

LU-12514 (utils: add "lustre_tgt" filesystem type) breaks scripts that used 'mount -t lustre' and expected to see targets.

In 2.12.*:

# mount -t lustre
/dev/mapper/mds1_flakey on /mnt/lustre-mds1 type lustre (ro,svname=lustre-MDT0000,mgs,osd=osd-ldiskfs,user_xattr,errors=remount-ro)
/dev/mapper/ost1_flakey on /mnt/lustre-ost1 type lustre (ro,svname=lustre-OST0000,mgsnode=192.168.122.75@tcp,osd=osd-ldiskfs,errors=remount-ro)
/dev/mapper/ost2_flakey on /mnt/lustre-ost2 type lustre (ro,svname=lustre-OST0001,mgsnode=192.168.122.75@tcp,osd=osd-ldiskfs,errors=remount-ro)
/dev/mapper/ost3_flakey on /mnt/lustre-ost3 type lustre (ro,svname=lustre-OST0002,mgsnode=192.168.122.75@tcp,osd=osd-ldiskfs,errors=remount-ro)
/dev/mapper/ost4_flakey on /mnt/lustre-ost4 type lustre (ro,svname=lustre-OST0003,mgsnode=192.168.122.75@tcp,osd=osd-ldiskfs,errors=remount-ro)
192.168.122.75@tcp:/lustre on /mnt/lustre type lustre (rw,flock,user_xattr,lazystatfs)
# mount -t lustre_tgt
# 

In 2.13 and on:

# mount -t lustre
192.168.122.75@tcp:/lustre on /mnt/lustre type lustre (rw,flock,user_xattr,lazystatfs,noencrypt)
# mount -t lustre_tgt
/dev/mapper/ost1_flakey on /mnt/lustre-ost1 type lustre_tgt (ro,svname=lustre-OST0000,mgsnode=192.168.122.75@tcp,osd=osd-ldiskfs,errors=remount-ro)
/dev/mapper/ost2_flakey on /mnt/lustre-ost2 type lustre_tgt (ro,svname=lustre-OST0001,mgsnode=192.168.122.75@tcp,osd=osd-ldiskfs,errors=remount-ro)
/dev/mapper/ost3_flakey on /mnt/lustre-ost3 type lustre_tgt (ro,svname=lustre-OST0002,mgsnode=192.168.122.75@tcp,osd=osd-ldiskfs,errors=remount-ro)
/dev/mapper/ost4_flakey on /mnt/lustre-ost4 type lustre_tgt (ro,svname=lustre-OST0003,mgsnode=192.168.122.75@tcp,osd=osd-ldiskfs,errors=remount-ro)
/dev/mapper/mds1_flakey on /mnt/lustre-mds1 type lustre_tgt (ro,svname=lustre-MDT0000,mgs,osd=osd-ldiskfs,user_xattr,errors=remount-ro)
