[HPDD-discuss] lfs find stuck

Dear All, I have deactivated an OST, so that I can migrate data off of it. For some strange reason when I try to run the migration script against this one OST, I do not see it doing anything for almost eternity. When I the same process with strace, I see it is trying to open files and move to next file. But I do not see it moving any files at all, this OST is 60% full, so I know for sure file exists. Can anybody help me understand this. Q) Do you think it can take hours together to find the first file to move? Any tips to debug this issue? Thank you, Amit
