HPUX/LINUX : NFS STALE HANDLE AT NFS CLIENT

     The VG minor number in the prod server and the QA server are inconsistent – this would result in NFS stale handle errors for the NFS clients after  a package failover

FFile system /sapmnt/DC1 exported to linux server, when package failover to SYSTEMP12.

Eexport file system on the linux show NFS stale handle.

Iissue:

MMinor number for volume group, /dev/vg_DC1_bin is different on both the node.

RRecommendations:

NNeed to adapt same minor number on both nodes.

F
fFor DC1 minor number is not same, Resulting in  NFS stale handle for exported FS.
