NFS mounted as readonly, why?
I have an NFS share that I export myself and then want to mount as readwrite. But for some reason it's mounted as readonly.
$ mount | grep test
127.0.0.1:/var/sharepath on /test type nfs4 (rw,relatime,vers=4.1,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=127.0.0.1,local_lock=none,addr=127.0.0.1)
$ cat /etc/exports | grep sharepath
/var/sharepath *(rw,sync,no_root_squash,no_subtree_check)
Until here it looks good. right?
However: touch: cannot touch ‘/test/asdf’: Read-only file system
What might be the reason?
PS: var itself is also read write:
$ mount | grep lvol0
/dev/mapper/vg01r5-lvol0 on /var type xfs (rw,relatime,seclabel,attr2,inode64,noquota)
mount nfs

The "rw" in our output means it's mounted (and exported) as read-write. What makes you think that it's mounted read only?

/test/<name>will cause it to try from root directory, try from./test/asdfor/var/sharepath/test/asdf(unless it's a spelling mistake, we all make those)

/testis a directory in root. That's correct. It is not~/testor something.

I'm aware this problem can have multiple sources. In our case it was really tricky.
In /etc/exports there was also a line that only said /var without any options etc. And that took precedence over /var/sharepath with all its options. After deleting that /var line it works. Probably a copy&paste error.
Another solution to similar problems might be setting priorities via export configuration.
