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.
