Anyone have any idea about what is this?
lfsck is not supported on Lustre 2.x filesystems as it hasn't been migrated to the new fid code. There is a project which I believe is sponsored by OpenSFS to implement an on-line equivalent but it's not due until sometime next year. There is some data available on the Whamcloud wiki site, I just found this via a quick search so there may well be better documentation elsewhere. http://wiki.whamcloud.com/display/PUB/OI+Scrub+and+inode+Iterator +Solution+Architecture Ashley, _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
