[Lustre-discuss] Does how to know OST to have data?

[Klaus Steden]

Hi Johnyla,

Use 'lfs getstripe <file>', i.e.

root# lfs getstripe /mnt/lustre/testfile1
OBDS:
0: lustre-OST0000_UUID ACTIVE
1: lustre-OST0001_UUID ACTIVE
/mnt/lustre/testfile1
        obdidx           objid          objid            group
             0          315726        0x4d14e                0
root#

This tells me that 'testfile1' is stored entirely on OST0.

good luck,
Klaus
