Re: Error with RTEMS on MVME5500

[Heinz Junkes <junkes@fhi-berlin.mpg.de>]

Bhavna,

on host 100.100.100.110 there must be a nfs server running.

Please check that host for nfs.server processes:

$ ps -ef | grep nfsd

rtems     5536  5516  0 18:01 pts/14   00:00:00 grep --color=auto nfsd

root     19606     2  0 Aug30 ?        00:00:00 [nfsd4]

root     19607     2  0 Aug30 ?        00:00:00 [nfsd4_callbacks]

root     19611     2  0 Aug30 ?        00:00:00 [nfsd]

root     19614     2  0 Aug30 ?        00:00:00 [nfsd]

root     19617     2  0 Aug30 ?        00:00:00 [nfsd]

root     19618     2  0 Aug30 ?        00:00:00 [nfsd]

and /etc/exports

that there is an entry for /tftpboot/rt_test3 like this:

$ more /etc/exports

# /etc/exports: the access control list for filesystems which may be exported

# to NFS clients.  See exports(5).

#

/tftpboot/rt_test3       100.100.100.0/24(rw,sync,no_subtree_check)

HTH,

Heinz
