[LU-9059] mount.lustre FATAL: unhandled/unloaded fs type 0 'ext3'

• Type: Bug

Description

This new error started appearing recently:
mount.lustre FATAL: unhandled/unloaded fs type 0 'ext3'

Pretty sure it's a side effect of the following mod recently landed:

commit a6e430e81669a6ab40ecae9b416dd2cdee45908c
LU-7481 utils: label lustre device correctly
https://review.whamcloud.com/24845

Backing out that one mod makes the problem go away.
In spite of the very alarming wording of the error, the mount seems to succeed just fine.

I am seeing this error message when I mount a ZFS OST on a system without ldiskfs installed.

{{# mount -t lustre ost02/ost02 /mnt/ost02
mount.lustre FATAL: unhandled/unloaded fs type 0 'ext3'

1. rpm -q lustre
   lustre-2.9.59_32_g62bc3af-1.el7.centos.x86_64
   }}

This is today's multi-rail branch, which was just synced with master.

re-open, new ticket, or is this a feature of my not having an entry in ldev.conf?

Hi Hongchao,

Can you please have a look at this issue when you return from the holiday? The mounts are succeeding and does not seem to be interrupting testing at the moment.

Thanks.
Joe
