[Lustre-discuss] lfsck reports ''Failed to get path for fid''
Our system consists of 1 MDS and 3 OST. One of OST crashed, so I use e2fsck to check and repair the local error first , then I use lfsck to check the whole system , but lfsck reports nearly 3 millions of error : ''Failed to get path for fid [0x7018bd:0x772726b6:0x0]'' with Hex number variates . Anyone have any idea about what is this?

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,
