Path issue Filesystem mounted with NFS(v4?)

[Heinz Junkes]

Hallo,

I am observing a strange problem with an NFS(v4) mounted filesystem and path usage.

I have mounted a filesystem via NFSv4 (/Volumes):

loc = 0x00820a20
    node_access = 0x007c2378, node_access_2 = 0x00000000, handler = 0x005c3474
type = nfs, mounted, read-write, target = /Volumes, dev = 141.14.131.192, root loc = 0x00913468

In the shell I can change there into a directory:

SHLL [/] # cd /Volumes/Epics/LogDir/Database
SHLL [/Volumes/Epics/LogDir/Database] # pwd
/Volumes/Epics/LogDir/Database

SHLL [/Volumes/Epics/LogDir/Database] # ls -l
total 20
-rw-r--r--  1 1001  1001  10694 Mar 23  2021 iocvmeIOC3.dbhcr
-rw-r--r--  1 1001  1001      0 Mar 23  2021 iocvmeIOC3.dbior
-rw-r--r--  1 1001  1001   5451 Mar 23  2021 iocvmeIOC3.dbl

I can now copy a file to here:

SHLL [/Volumes/Epics/LogDir/Database] # cp /etc/passwd .
SHLL [/Volumes/Epics/LogDir/Database] # ls -l
total 24
-rw-r--r--  1 1001   1001   10694 Mar 23  2021 iocvmeIOC3.dbhcr
-rw-r--r--  1 1001   1001       0 Mar 23  2021 iocvmeIOC3.dbior
-rw-r--r--  1 1001   1001    5451 Mar 23  2021 iocvmeIOC3.dbl
-rwxrwxrwt  1 65534  65534     14 Jul 11 11:28 passwd
SHLL [/Volumes/Epics/LogDir/Database] # cat passwd
root::0:0::::
SHLL [/Volumes/Epics/LogDir/Database] # rm passwd
SHLL [/Volumes/Epics/LogDir/Database] # ls -l
total 20
-rw-r--r--  1 1001  1001  10694 Mar 23  2021 iocvmeIOC3.dbhcr
-rw-r--r--  1 1001  1001      0 Mar 23  2021 iocvmeIOC3.dbior
-rw-r--r--  1 1001  1001   5451 Mar 23  2021 iocvmeIOC3.dbl

If I now specify the path instead of “.”, the file appears one dir up ????

SHLL [/Volumes/Epics/LogDir/Database] # cp /etc/passwd /Volumes/Epics/LogDir/Database/passwd
SHLL [/Volumes/Epics/LogDir/Database] # ls -l
total 20
-rw-r--r--  1 1001  1001  10694 Mar 23  2021 iocvmeIOC3.dbhcr
-rw-r--r--  1 1001  1001      0 Mar 23  2021 iocvmeIOC3.dbior
-rw-r--r--  1 1001  1001   5451 Mar 23  2021 iocvmeIOC3.dbl
SHLL [/Volumes/Epics/LogDir/Database] # ls -l ..

SHLL [/Volumes/Epics/LogDir/Database] # cat ../passwd

Any Idea what might go wrong? Any fix?
