Native mounts of Taiga using the Lustre client are greatly preferred for superior performance and increased stability, however sub-directories of Taiga can be mounted via NFS in cases where that is necessary.  The NFS service is accessed via the HA taiga-nfs.ncsa.illinois.edu endpoint.  The NFS endpoint is currently comprised of 4 servers that are directly connected to the 100GbE public-facing storage network and via redundant links to Taiga's HDR Infiniband core fabric.   If you need an NFS export please file a ticket with the STO: Taiga component flag and the storage team will assist in getting the exported provisioned.  

Taiga Allocation Access Guidelines

Access to data on Taiga is ultimately governed by normal POSIX permissions and more specifically so, group membership.  Some common scenario's are below:

Direct Investment

If you/your team has a direct investment on the Taiga system, access to your area is governed by an LDAP group that was created during the allocation onboarding; this group name often (but not always) looks like taiga_prj_XXXXX.  Your group's PI (and whomever they've designated) are able to add you to the LDAP group that controls access to your allocation via NCSA's Identity portal.  Once you are a member of this group, you should have access to the data.

HPC System Project Directory Access

Many NCSA compute environments leverage Taiga for their project space.  For example, Delta's /projects mount maps to the full path /taiga/nsf/delta.  Accessing data that is within project areas requires membership to the compute/system allocation for the system in question (be it Delta, HOLL-I, etc.).  The compute allocation PI should be able to get you added to that group which will gain you access to this data.  

Radiant Allocation

Radiant allocations on Taiga live underneath the full path, /taiga/ncsa/radiant/ and are by default only available via NFS mount within Radiant instances associated with that allocation.  If access of this data outside of Radiant is needed, please speak with the storage team by opening a ticket with the STO: Taiga component flag and someone from the storage team will assist you with your needs.
