As you may remember I had a RH 7.2 NFS server (i686) running the 2.4.9-21smp kernel, exporting an ext2 directory (~70GB). Sometimes I discovered problems when linking together a large static library on two clients which had different architecture (ia32 ia64), both running RedHat but with different kernels (ia32 was running 2.2.19-6.2.7 and ia64 was running a stock 2.4.18 with ia64 patchset). The error message I got on the ia32 client was : ar: Linux2.i86pc.gnu.dbg/libmpi.a: Input/output error gmake[4]: *** [Linux2.i86pc.gnu.dbg/libmpi.a] Error 1 and on the ia64 client it was : ar: Linux2.ia64.gnu.dbg/libmpi.a: Stale NFS file handle gmake[4]: *** [Linux2.ia64.gnu.dbg/libmpi.a] Error 1 Now, since both these clients got almost the same problem (ok the 2.2.19 client reported -EIO, and the 2.4.18 client -ESTALE), I tried upgrading my server to a stock 2.4.18 kernel and that actually helped ... Can you give me any more details to why it helped upgrading my NFS server to 2.4.18 ?
