[Lustre-discuss] lfsck reports 'Failed to get path for fid'

[bob lin]

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?
