Does how to know OST to have data when mount lustre OST? My disk is FCSAN. Thank you! [root at OSS2_MASTER ~]# uname -a Linux OSS2_MASTER 2.6.9-67.0.7.EL_lustre.1.6.5smp #1 SMP Mon May 12 22:02:50 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux
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

Hi Klaus, Thank you! Sorry, I take a mistake. Does how to know OST to have data when doesn''t start lustre OST? OSS1 and OSS2 share the OST(/dev/sdd1), now OSS1 is working. I want to know /dev/sdd1 have data in OSS2 machine. Thank you!

Hi Klaus, Thank you! I have found a way to check the raw disk by the command "tune2fs -l / dev/sdd". Thank you answer!
