Re: [HPDD-discuss] how to access the data in a given OST directly
A method for doing this with an ldiskfs backend is covered in the Lustre
manual:
http://build.whamcloud.com/job/lustre-manual/lastSuccessfulBuild/artifact...
This method is suitable for debugging or exceptional situations, but not
for routine access.
In short:
1. Use lfs getstripe to obtain the obd index and object number.
2. Use debugfs to access the data on disk (e.g. stat, dump).

Hi,
If I have known a piece of data resides in a given OSS/OST. Is it possible to
access it directly with using lustre client ?
To be specific, the problem is when I am on an OSS/OST, I want to access the
local data of this OSS/OST without referring to lustre client.
Is it possible, how can I achieve that ?
Thanks in advance.
