Mount NFS error

ndtatlive · 09-20-2018, 04:02 AM

Dear all,

I have a NFS server (AIX, IP: 10.86.28.3)

Code:

bash-4.2# cat /etc/exports 
/bk_devbi -sec=sys:krb5p:krb5i:krb5:dh,rw
/bk_prdbi -sec=sys:krb5p:krb5i:krb5:dh,rw

on AIX client, mount NFS successfully by this cmd

Code:

mount 10.86.28.3:/bk_devbi /svt_tmp

but on SUSE client, the errors are:

Code:

devbidb:/soft # showmount -e 10.86.28.3
Export list for 10.86.28.3:
/bk_devbi (everyone)
/bk_prdbi (everyone)

devbidb:/soft # mount 10.86.28.3:/bk_devbi /devbi_todr/
mount.nfs: Remote I/O error

devbidb:/soft # mount -vvvv 10.86.28.3:/bk_devbi /devbi_todr/

Please help.

Thank you.

What does

Code:

showmount -e 10.86.28.3

from the SUSE box report? Same as from the other AIX client?

Could this be a version parsing mixup or bug? Try adding explicit -t nfs to your mount command, and if that doesn't work, try -t nfs4 instead.
