[lustre-discuss] problems to mount MDS and MDT

Mon May 17 10:33:03 PDT 2021

Hello

i have a problem to mount the mds/mdt luster, it wont mount at all and
there is no message errors at the console

-it does not show errors or messages while mounting it

here are some debug file logs

i specify it is a new project that i am doing.

the version and packages of luter installed:
kmod-lustre-2.12.5-1.el7.x86_64
kernel-devel-3.10.0-1127.8.2.el7_lustre.x86_64
lustre-2.12.5-1.el7.x86_64
lustre-resource-agents-2.12.5-1.el7.x86_64
kernel-3.10.0-1160.2.1.el7_lustre.x86_64
kernel-debuginfo-common-x86_64-3.10.0-1160.2.1.el7_lustre.x86_64
kmod-lustre-osd-ldiskfs-2.12.5-1.el7.x86_64
kernel-3.10.0-1127.8.2.el7_lustre.x86_64
lustre-osd-ldiskfs-mount-2.12.5-1.el7.x86_64

the system(os) Centos 7

the kernel
Linux lustre-mds1 3.10.0-1127.8.2.el7_lustre.x86_64
 cat /etc/redhat-release

when i mount the luster file-system it wont show up and no errors

mount -t lustre /dev/sda /mds

lctl dl  does not show up

df -h   no mount point for /dev/sda

lctl dl

shows this:
lctl dl
  0 UP osd-ldiskfs lustre-MDT0000-osd lustre-MDT0000-osd_UUID 3
  2 UP mgc MGC10.0.1.70 at tcp 57e06c2d-5294-f034-fd95-460cee4f92b7 4
  3 UP mds MDS MDS_uuid 2

but unfortunately it disappears after 03 seconds

lctl  dl shows nothing

lctl dk

shows this debug output
