I have a system with a failed OST. Resolved any hardware issues and e2fsck the OST before mounting. e2fsck seem to have quite of bit of repair done. I remounted the OST and everything looked fine. I did not run lfsck yet. Would lfsck restore any files that were in the OST''s /lost&found to the lustre''s fs /lfs/lost&found? Also after the system was restored, another OST went in to a read only mode because the fibre connection to the disk died. Currently the disk is down. Users started reporting files that some of the files were 0byte size. I checked them out and while some were the downed disk, there were files NOT mapped to the failed OST. Files that were 0byte size are now coming back with a "No such file or directory". I''m really worried now that I might be losing data or the MDS is starting to disconnect the inodes. Can anyone help? What can I do about this situation other then bring back the disconnected OST... Thanks, -Alex
