Re: [HPDD-discuss] [Lustre-discuss] strange symbolic link behavior on mdt?

I am testing symbolic link behaviour and not getting the expected results. In the simplest case, I create one valid and one invalid link: -rw-r--r-- 1 root root 0 Oct 13 11:17 exist lrwxrwxrwx 1 root root 5 Oct 13 11:17 lexist -> exist lrwxrwxrwx 1 root root 7 Oct 13 11:17 lnoexist -> noexist When I look at the meta data through the ldiskfs mounted mdt the link paths are not shown: -rw-r--r-- 1 root root 0 Oct 13 11:17 exist lrwxrwxrwx 1 root root 5 Oct 13 11:17 lexist lrwxrwxrwx 1 root root 7 Oct 13 11:17 lnoexist

And trying to get a bit more info: # file * exist: empty lexist: unreadable symlink `lexist' (Invalid argument) lnoexist: unreadable symlink `lnoexist' (Invalid argument) If I restart lustre by unmounting and re-mounting all the lustre mount points (MDT, ODT's, client) the link paths show up in the ldiskfs mounted mdt: -rw-r--r-- 1 root root 0 Oct 13 11:17 exist lrwxrwxrwx 1 root root 5 Oct 13 11:17 lexist -> exist lrwxrwxrwx 1 root root 7 Oct 13 11:17 lnoexist -> noexist file * exist: empty lexist: symbolic link to `exist' lnoexist: broken symbolic link to `noexist' I've also just tried just re-mounting the ldiskfs mount point but that did not help. Is there any way to correct this without having to restart lustre? I experimented with running lfsck w/o restart all of lustre but I could not see that it was running or had done anything useful yet.
