[Lustre-discuss] ll_recover_lost_found_objs in Lustre 1.6.x?

[Jason Hill]

Yemi,

Yes you can use ll_recover_lost_found_objs, we have had very recent experience
here with using it against a 1.6.5 filesystem. We did however go get the newest
version from the Lustre 1.8 branch.

If the O directory doesn't exist you'll need to run it twice, and you will need
to specify the full path to the lost+found directory otherwise the tool will
complain quite a bit.

The manual describes the 'll_recover_lost_found_objs' command which sounds like it will restore the directory structure. Is this utility available for 1.6.5? Where can I find it?
