Use the

utility to translate the primary inode ID into the file name.
Removing a node from a cluster
In the following procedure, the cluster contains four nodes:
FSN1
,
FSN2
,
FSN3
, and
FSN4
.
FSN4
is the node being removed. The user NIC for
FSN4
is
bond0:1
. The file system name is
ibfs1
,
which is mounted on
/ibfs1
and shared as
ibfs1
through NFS and SMB .
FSN3
and
FSN4
are
the failover pair, and
bond0:2
is configured as the stand-by interface.
1.
Stop High Availability:
ibrix_server -m –U
2.
Verify that the Active Fusion Manager is on a server other than
FSN4
. Run the following
command from
FSN4
:
ibrix_fm -i
If the Active Fusion Manager is on FSN4, move the Fusion Manager to nofmfailover mode:
ibrix_fm -m nofmfailover
3.
Migrate all segments from
FSN4
to its failover partner (
FSN3
):
ibrix_fs -m -f ibfs1 -h FSN4,FSN3
NOTE:
If there is a large number of segments to be migrated and/or segments can be
migrated to several FSNs (in SAN environments), run the following command instead:
ibrix_fs -m -f ibfs1 -s LVLIST -h FSN_name
4.
Remove the High Availability configuration between
FSN4
and
FSN3
:
a.
Stop NIC monitoring for the user NICs:
ibrix_nic -m -h FSN3 -D FSN4/bond0:1
ibrix_nic -m -h FSN4 -D FSN3/bond0:1
b.
Remove the backup NICs:
ibrix_nic -b -u FSN4/bond0:2
ibrix_nic -b -u FSN3/bond0:2
c.
Remove the backup server:
ibrix_server -b -U -h FSN4
ibrix_server -b -U -h FSN3
5.
If
FSN4
is configured for DNS round robin or there are NFS/SMB clients mounting file systems
directly from
FSN4
, you must migrate the user NIC IP address to another FSN. Continue with
step 6 if the
FSN4
NIC IP address has been removed and there are no clients accessing data
from
FSN4
.
a.
Create a new placeholder NIC on
FSN3
you will be migrating IP address to:
ibrix_nic -a -n bond0:3 -h FSN3
b.
Migrate NIC
bond0:1
from
FSN4
to
bond0:3
on
FSN3
:
ibrix_nic -s -H bond0:1/FSN4,bond0:3/FSN3
6.
Stop NFS and SMB services on
FSN4
:
ibrix_server -t -s NFS -c stop
ibrix_server –t –s cifs –c stop
