Ignite backup problem ?
Found Ignite backup failed, from the logfile.
While re-running getting this error message continously :
"NFS server srv-abc not responding still trying."
details:
* bdf hangs
* bdf -l : works fine ,all local filesystems shows.
* tried to ping the server srv-abc , its pingable.
* found someone earlier mounted one nfs filesystem , from srv-abc server : ( using this command : # mount -F nfs srv-abc:/mnt/fs1 /remotefs ) , and now this filesystem is no longer available , causing bdf to hang. Even # cd /remotefs hangs.
Whats wrong. What can be done , to unmount that filesystem.
I have tried :
# umount /remotefs
nfs umount: nfs_unmount: /remotefs: is busy
umount: return error 1.
Pls suggest.
Thanks ,

Re: Ignite backup problem ?
Just like what you said, the remote file system is not longer available and that is why bdf hangs.
Have you tried to stop/restart nfs.server and nfs.client ?
Are you doing an ignite backup cross the network ?
Have a look at ignite's man page, there may be an option to by pass that directory.
thanks

Re: Ignite backup problem ?
use fuser to kill the processes using files in this file system if any.
#fuser -ck /remotefs
The try unmounting it. If do not succed then if there are no other NFS file systems exported/imported from this server do
#/sbin/init.d/nfs.client stop
#/sbin/init.d/nfs.server stop
#/sbin/init.d/nfs.core stop
If the issue gets resolved by this then restart the services again.

Re: Ignite backup problem ?
The earlier post actually concerned about the bdf problem only. So for the ignite problem I think you should specify to backup only vg00 using -x switch.
Still it may give problem as it will use bdf and fstab to find out the currently unmounted file systems without which it can not proceed.

Re: Ignite backup problem ?
This is the command I am using for Ignite backup :
* /opt/ignite/bin/make_tape_recovery -A -v -a /dev/rmt/0mn -x inc_entire=vg00 -n 2
* Also this is a adoptive node of a 2 node cluster . Will be there any impact , if the nfs.client stop , nfs.server stop & nfs.core stop , executes.
Please suggest.
Thanks.

Re: Ignite backup problem ?
If it is part of cluster, then I would recommend to reboot it as the other node will take care of applications. The impact may there if some of the packages require NFS services.

Re: Ignite backup problem ?
do a nfs.server stop/start and nfs.client stop/start on the adoptive node should not have any impact on the packages as long as the package is not running on the adoptive node.
do a showmount -e first on that node to see if any file system being exported.
thanks

Re: Ignite backup problem ?
showmount shows the following error:
# showmount -e
showmount: infsrv12: RPC: Program not registered.
What could be the problem.
Thanks.

Re: Ignite backup problem ?
Some body is trying to use /remotefs.
Check as,
# fuser -k /remotefs
It will release that file system usage.
# cd /
# umount /remotefs
It is unmounted now.
Try to restart NFS as,
# /sbin/init.d/nfs.server stop
# /sbin/init.d/nfs.server start
# /sbin/init.d/nfs.core stop
# /sbin/init.d/nfs.core start
# /sbin/init.d/nfs.client stop
# /sbin/init.d/nfs.client start
Check rpcinfo status for debugging.
