make_net_recovery question

[Brent DeGennaro]

I just started tinkering with Ignite and attempted to make a network recovery archive and I'm getting this error.


Unable to mount or write host:/var/opt/ignite/recovery/archive/host2
On host you may need to:
mkdir -p /var/opt/ignite/recovery/archives/host2
chown bin:bin /var/opt/ignite/recovery/archives/host2
vi /etc/exports (add or modify an entry)
exportfs -av



I've done all of these things so I'm not sure where my problem is. Any help would be greatly appreciated.

Thanks

is NFS running?

check /etc/rc.config.d/nfsconf
NFS_CLIENT=
NFS_SERVER=

set both to 1 on the server, and set NFS_CLIENT to 1 on the client.

run
/sbin/inti.d/nfs.core start
/sbin/init.d/nfs.client start
/sbin/init.d/nfs.server start

on host2, run rpcinfo to see if you have all the required rpc stuff needed for nfs, then run the following on host2 to verify the processes:

UNIX95= ps -efH|head -1; UNIX95= ps -efH|egrep "inetd|rpc|mount|nfs"|grep -v grep; rpcinfo -p|egrep "service|nfs"; showmount -e; mount -p

the last two commands in that string should show you the exported and mounted file systems for host2.

Bernhard,

On my ignite server:

NFS_CLIENT=1
NFS_SERVER=1


On the client:

NFS_CLIENT=1
NFS_SERVER=1

try if you can maunally mount and umount an exported filesystem.

Also use nslookup to verify hostname resolution and reverse lookup of ip adress match.

Bernhard

Mark,

Looks like everything is there.

host:/var/opt/ignite/clients /var/opt/ignite/recovery/client_mnt nfs defaults,NFSv3 0 0

Brent,

How your /etc/exports file looks like on the Ignite server? On my Ignite server I have:

more /etc/exports

/var/opt/ignite/clients -anon=2
/var/opt/ignite/recovery/archives/clienthostname -anon=2,access=clienthostname

HTH,

Elena.

[Brent DeGennaro]

Elena,

I have the same thing.

$ more /etc/exports
/var/opt/ignite/clients -anon=2
/var/opt/ignite/recovery/archives/host2 -anon=2,access=host2

[Francesco Campalastri]

It should work!

Try to mount it manually from host2
On host2
# mount \
host:/var/opt/ignite/recovery/archives/host2 \
/mnt/

# touch /mnt/test

What happens?


Where /var/opt/ignite/recovery/archives/host2 stays? What logical volume on?

On host:
# exportfs
# mount

[Brent DeGennaro]

This is from the recovery.log

Ok, on ej:

# mount
# exportfs


and give us the output please,

[Elena Leontieva]

Brent,

I wonder if you have a problem with the /etc/lvmtab? Do strings /etc/lvmtab and vgdisplay -v vg00. Do your Cur PV and Act Pv are consistent and lvmtab looks as you expect?

Just a thought,
Elena.

[Marvin Strong]

hmm just a wild guess,

are sure certain the ownership is bin:bin for /var/opt/ignite/recovery on both sides? And the permissions are set correctly 755.

[Brent DeGennaro]

755 on both hosts

[Bernhard Mueller · Accepted solution]

Brent,

this looks like you have an exported directory /var/opt/ignite/recovery/archives/earl.morris.com on ej

but earl wants to mount
ej:/var/opt/ignite/recovery/archives/earl

....

So you should check /etc/hosts and /etc/nsswitch.conf plus your DNS servers to get things straight.

For your current issue it *might* help to
run exportfs -ua cd /var/opt/ignite/recovery/archives
mv earl.morris.com earl
edit /etc/exports and remove .morris.com
run exportfs -va

Regards,
Bernhard

[Francesco Campalastri]

I totally agree with Bernhard,
probably the servers have two different name resolution.

Probably
/etc/hosts differ between two servers or
/etc/resolv.conf differs or
/etc/nsswitch.conf differ.
