Hi all,
one of our ((Lustre 2.5.3, ZFS 0.6.3) OSTs got filled up to >90%, so I deactivated it and am now
migrating files off of that OST.
Checking the list of files I am currently using, I can verify that the migration is working: Lustre
tells me that the top of the list is already on some other OSTs, the bottom of the list still resides
on the OST in question.
But when I do either 'lfs df' or 'df' on the OSS, and don't see any change in terms of bytes, while
the migrated files already sum up to several GB.
Is this a special feature of ZFS, or just a symptom of a broken OST?
I think I have seen this behavior before, and the "df" result shrank to an expected value after the
server had been rebooted. In that case, this seems more like a too persistent caching effect -?
Cheers,
Thomas
