write fails with read-only error

Robeen

Red Hat Enterprise Linux Server release 7.4 (Maipo)

Hello Team,

kindly advise why I am unable to write on NFS.

mkdir: cannot create directory ‘test’: Read-only file system

os5500.mtg.local:/NFS/DWARE /backupdw nfs rw,hard,rsize=65536,wsize=32768,proto=tcp,vers=4,timeo=600,actimeo=0 0 0

Thanks,

Hi.

Show result for command:

   showmount -e os5500.mtg.local

Also check how mount /NFS/DWARE on os5500.

FS can be shared as read-only.

FS on NFS server can be mounted as read-only.

Regards,

Nik

How do I share the NFS as write also?

I have mounted NFS as write permission also.

os5500.mtg.local:/NFS/DWARE /backupdw nfs rw,hard,rsize=32768,wsize=32768,proto=tcp,vers=4,timeo=600,actimeo=0 0 0

Hi.

This problem may be on NFS-server side or on NFS-client side.

Do You have other system that mount os5500.mtg.local:/NFS/DWARE and can write it?

NFS client have ip from this list: 10.215.227.28,10.215.227.29,10.10.105.103,10.10.104.104,10.124.0.70,10.124.0.88 ?

Is os5500.mtg.local general server or some NAS storage ? Do You know options how this FS shared ?

Hi,

I checked the share option.. it is read-write. Other servers (10.215.227.28,10.215.227.29) can write to it. I have no idea if it is on some NAS storage.
