Top UNIX (Solaris/AIX/HP-UX) Issues/Workarounds/Best Practices for NFS v3/v4.0
This article lists the top known issues, workarounds and best practices for UNIX clients (Solaris/AIX/HP-UX), when used with NetApp FAS controllers running Data ONTAP 7-Mode or clustered Data ONTAP.
Known Issues and Workarounds:
Solaris:
- Issue:
Solaris 11:nfs-kerberos
fails with thepermission denied
error ifallow_weak_crypto
is disabled.
Description: Withkinit
enabled on these clients,nfs-kerberos authentication
will fail and displays:kinit: No supported encryption types (config file error?)
.
Workaround: Addallow_weak_crypto=yes
in/etc/krb5/krb5.conf
to getnfs-kerberos
working. - Issue:
Solaris 10/11:Error=5
seen while server SFO/unplaned reboot.
Description: When the server goes through an unplanned SFO or reboot, the client side application might see anError=5
.
Workaround: For Solaris 11.2 this is fixed in following SRU. Oracle Solaris 11.2.6.4.0 Support Repository Update (Oracle Solaris 11.2 SRU6.4) ( Doc ID 1962769.1 ). For Solaris 10, this if fixed by patch 150401-21.So we need to have patch 150401-21 OR above.
AIX:
- Issue:
AIX 7.1 TL0 SP4:nfsv4
mount with clustered Data ONTAP fails with the error 'data IP is not in hosts database
'.
Description: Mount fails with NFS v4.0 displaying the error 'data IP is not present in host database
'.
Workaround: Add data LIF IP in the/etc/hosts
file on the client to resolve the issue.
HP-UX:
- Issue:
HP-UX 11i v3: Creating a directory on thenfsv4
mount might result in permission denied.
Description: Unable to create directories on an NFS v4 mount since the default UID/GID for root user must be 0/0; however, it is in this version of HPUX OS 0/3 (root/sys), so the storage system responds with the error message:NFS4ERR_BADOWNER
.
Workaround: Addsys entry
in theetc/group
file on the storage system (Data ONTAP 7-Mode). In the case of clustered Data ONTAP, create Unix-group for sys to resolve the issue.
Best Practices:
