how to access the data in a given OST directly
by jyizheng
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.

lfs_migrate failure
by Arman Khalatyan
Hello,
I wondered is lfs_migrate is only for striped files?
when I run on non striped one on lustre 2.4.1 I get following error:
lfs_migrate /lustre/arm2arm/tileimg_vis.png
lfs_migrate is currently NOT SAFE for moving in-use files.
Use it only when you are sure migrated files are unused.
If emptying OST(s) that are not disabled on the MDS, new
files may use them. To prevent MDS allocating any files on
OSTNNNN run 'lctl --device %{fsname}-OSTNNNN-osc deactivate'
on the MDS.
Continue? (y/n) y
/lustre/arm2arm/tileimg_vis.png: cannot swap layouts between
/lustre/arm2arm/tileimg_vis.png and a volatile file (Operation not
permitted)
error: migrate: migrate stripe file '/lustre/arm2arm/tileimg_vis.png' failed
Thanks,
Arman.
