Hello, We have some problems with the newest Lustre version. After upgrading from 1.8.1.1 to 1.8.2 stripping over OST pools seems to stop working: [ymmagrys at ui ymmagrys]$ lfs pool_list scratch Pools from scratch: scratch.pool1 scratch.pool0 [ymmagrys at ui ymmagrys]$ mkdir test [ymmagrys at ui ymmagrys]$ lfs setstripe -p scratch.pool0 test can''t find fs root for ''test'': -19 ''test'' is not on a Lustre filesystem error: setstripe: create stripe file ''test'' failed Of course I am on a mounted Lustre fs. I wonder if anyone else has the same problem? Is there any known solution/workaround for this problem? Cheers, Marek -- Marek Magrys Systems Administrator ACC Cyfronet AGH-UST

Can you please file a bug with details (including relevant /var/log/messages output on the client and servers).

Still, it''s strange, because there was absolutely nothing suspicious in the logs on the clients and servers. Thanks for help. Cheers, Marek -- Marek Magrys Systems Administrator ACC Cyfronet AGH-UST

Thanks for help.Actually, i can easily reproduce the same problem on 1.8.2 by passing a relative path to setstripe -p. This seems to be due to the patch from bug 19919 which was landed for 1.8.2.
