Создаю РАМ диск. Создаю на нём ЛВМ. Начинаю создавать файловую систему.
Ext4 - создаёт успешно.
mkfs.xfs -f /dev/... - несоздаёт, и код возврата ноль!!Что неправильно делаю? Куда копать? Под ЦентОС 7 тоже самое работало, под Убунту 16.04 - нет.
Спасибо!
Вот как создаю ФС:
me: ~ $ sudo mkfs.ext4 /dev/developGRP/developVLM
me: ~ $ sudo mkfs.xfs -f /dev/developGRP/developVLM
meta-data=/dev/developGRP/developVLM isize=512 agcount=2, agsize=7680 blks
= sectsz=4096 attr=2, projid32bit=1

data = bsize=4096 blocks=15360, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0 ftype=1
log =internal log bsize=4096 blocks=1605, version=2
= sectsz=4096 sunit=1 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
me: ~ $ echo $?
0
me: ~ $ sudo mount /dev/developGRP/developVLM /mnt
mount: wrong fs type, bad option, bad superblock on /dev/mapper/developGRP-developVLM,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.

Вот скрипт создания RAM диска и LVM:
#!/bin/bashset -x
set -e
declare -r blckDev="/dev/ram0"
declare -r name_vg="developGRP"
declare -r name_lv="developVLM"
if ! egrep "^brd[[:space:]]" /proc/modules ; then
modprobe brd max_part=10 rd_size=128000 # Size is in kb by default.
fi
test -b "${blckDev}"
if ! pvs "${blckDev}" ; then
pvcreate "${blckDev}"
fi
if ! vgs "${name_vg}" ; then
vgcreate "${name_vg}" "${blckDev}"
fi
if ! lvs "${name_vg}/${name_lv}" ; then
lvcreate --extents "50%FREE" --name "${name_lv}" "${name_vg}" "${blckDev}"
fi
vgscan --mknodes --cache
Вот логи из консоли, как всё запускалось, коды возврата:
