Ontap 9.3 Nblade.nfsV4PoolExhaust File-ID Reverse Search

Hi all,


we had a big outtage on the weekend,

an application farm took down the NFS Service on a shared Metrocluster for 3rd party customers.


EMS Message:

My question is, I can use the volume file show-filehandle if I have the past, the application developer need the reverese way,
I have the file-ID and need the path inc. file name,
could please anyone assist?
cluster1::> volume file show-filehandle -vserver vs0 -path /vol/vol1/file1.txt
             Vserver                    Path
             ----------------------     ---------------------------
             vs0                         /vol/vol1/file1.txt

             flags   snapid  fileid     generation  fsid        msid          dsid
             ------- ------  ---------  ----------  ----------  ------------  ------------
             0x0     0       0x60       0x206b6     0x402       0x80000402    0x402

Hi all,


solved it with a third party software which we use for indexing our file service, so the paths are available,
