5. Verify that the stripe count on the file system has been changed, as shown in the following
example:
sfs> show filesystem scratch
Name: scratch
OSTs: ost[1-4]
State: stopped
Mountpoint: /mnt/scratch/
Stripe size: 4194304
Stripe count: 4
.

.
6. Start the file system, as shown in the following example:
sfs> start filesystem scratch
You must then recreate the existing files to change their striping pattern (see Section 9.27.2.1).
9.27.2.1 Recreating files
You cannot change the striping configuration on an existing file; however, you can recreate a file and
change the striping configuration on the new file.
To recreate a file with a new striping configuration, perform the following steps:
1. Use the
cp
command to copy the incorrectly striped file to a new file name, as shown in the following
example, where the incorrectly striped file is called
data.1
:
# lfs getstripe data.1
0: ost1_UUID
1: ost2_UUID
2: ost3_UUID
3: ost4_UUID
./data.1
obdidx objid objid group
2 1886 0x75e 0
# cp data.1 data.new
# lfs getstripe data.new
OBDS:
0: ost1_UUID
1: ost2_UUID
2: ost3_UUID
3: ost4_UUID
./data.new
obdidx objid objid group
0 1860 0x744 0
1 1856 0x740 0
2 1887 0x75f 0
3 1887 0x75f 0
